哈囉各位聽眾大家好 02:15
歡迎收聽最新一集的博音 02:16
不知道你現在收聽的時候 02:17
是早上還是晚上 02:19
是不是正準備要入眠 02:20
或是剛剛才起床 02:21
但是感覺沒有睡飽呢 02:22
今天要聊這集主題呢 02:24
是我個人非常感興趣 02:25
也深受其困擾 02:27
幾乎是一輩子的主題 02:29
那就是睡眠 02:30
那我們請來就是哇賽心理學的站長 02:31
我們來歡迎的是蔡宇哲老師 02:33
博恩好 02:35
各位聽眾朋友大家好 02:36
我是宇哲 02:37
很開心在這裡 02:38
又可以來跟大家聊聊睡覺這件事 02:39
其實今天這集是不是要聊的話 02:42
可以聊非常非常非常久 02:43
對 因為基本上我們在睡眠這個主題 02:45
我們開過36小時的工作坊 02:48
02:51
看我們想要聊多久 02:51
都可以聊多久 02:54
好 那我就先 02:55
針對一些我個人的疑問 02:56
然後可能會有一些天馬行空的問題 02:58
然後再請教一下 03:01
學術上面到底有沒有看過類似的現象 03:02
我第一個非常困惑的事情是 03:06
我們到底為什麼需要睡覺 03:08
為什麼會需要睡覺 03:09
如果從生物體來講的話 03:11
最簡化的講法就是 03:12
你不睡覺就會死 03:14
對 這個第一個 03:17
我們從動物研究裡面 03:17
其實也發現 03:19
因為一剛開始做研究的睡眠學者 03:19
他也非常想知道這個問題 03:22
可是你不能拿人做實驗 03:24
怎麼辦 03:26
就是用老鼠 03:26
所以就讓老鼠 03:27
一直處於不睡覺的狀態 03:28
那研究發現如果正常情況底下 03:30
他大概經過四到六個禮拜 03:33
老鼠就會死亡 03:35
那另外 死亡 03:37
到底是因為什麼原因死亡呢 03:38
一剛開始 研究者也覺得說 03:40
如果是因為心臟的關係 03:42
心臟會出現病變嘛 03:43
那其他地方會出現病變 03:45
所以他們很想知道 03:47
到底 03:48
沒有睡眠會導致哪個地方出問題 03:48
那結果發現呢 03:51
沒有一致性的答案 03:52
也就是說呢 03:54
有一些可能心血管有問題 03:54
有一些可能其他的地方問題 03:56
但是都不會統一指向哪裡 03:58
那最後的一個研究 04:01
他發現最終 04:02
你可以有比較明確解答的是 04:04
他們到後期 04:07
他的熱量的調節出現失衡的情況 04:09
簡單地講這些老鼠 04:14
他吃的會比平常的多一倍 04:15
就是他吃很多 04:18
可是他的體重變成是本來的一半 04:19
所以大家想像你吃很多 04:23
可是你又越來越瘦 04:24
這個是我們剛剛講的 04:26
他整個能量系統的失衡 04:27
那能量系統的失衡 04:29
連帶的我們身體的整個系統 04:30
他都會出狀況 04:33
好那這個是動物研究 04:34
那我們有提到 04:35
其實人類身上 04:36
你不能做這種研究 04:38
只有老鼠做過嗎 04:39
有其他動物嗎 04:40
我想知道 04:41
其他動物其實比老鼠更高階的 04:42
通常不太能做 04:46
你也知道會有 IRP 的問題 04:47
更何況在現在 04:49
它其實是越來越嚴格 04:50
但是在人類史上 04:52
它其實曾經出現一種 04:53
非常特別的一種腦部的疾病 04:55
我要講這個疾病之前 04:58
我要先問博恩一個問題 04:59
假設 05:01
假設你知道了 05:02
你有一種家族性的遺傳疾病 05:03
那這種家族性遺傳疾病 05:06
有可能在你四五十歲的時候發病 05:08
那萬一發病 05:11
最後一定會在大約 05:12
幾十個禮拜當中會死亡 05:15
但不一定會發病 05:17
就有可能會發病 05:19
但不一定會發病 05:20
那現在 在你年輕的時候 05:21
有一種檢測方法 05:23
檢測你有沒有帶有這種基因 05:24
你會去檢測嗎 05:27
會啊 05:27
真的 05:28
會啊 05:29
但是檢測出來如果有 05:29
最後 05:31
要麼發病 05:32
要麼不發病 05:33
那只要發病就一定會out 05:34
對啊 05:36
在這種情況你決定 05:36
一定會 05:38
一定會檢測 05:38
要知道啊 05:39
你實在太有勇氣了 05:40
什麼意思啊 05:41
我真的不懂 05:42
為什麼 05:43
會有那個鴕鳥心態 05:44
沒有 其實在這個故事當中 05:45
其實有不少人 05:48
他是選擇不檢測 05:49
為什麼 05:51
因為他會出現一種壓力 05:52
就是我有可能會出現一種 05:54
類似絕症這種情況 05:57
那到底會不會出現不知道 05:59
所以他們就會覺得 06:01
我從年輕 06:03
我就要活得非常的兢兢業業 06:03
好 那我為什麼要問這個問題呢 06:06
在大概一百多年前吧 06:08
曾經有一種疾病叫 06:10
致死性家族失眠症 06:12
它是一種遺傳疾病 06:15
然後它是一種大腦當中的 06:16
蛋白的突變 06:18
那這種蛋白的突變呢 06:21
因為帶有基因 06:22
然後一直傳下去 06:23
那它最典型的就是 06:25
等到他大概40到60歲的時候 06:26
有可能會發病 06:29
那一旦發病 06:30
最後他就會越來越難睡 06:31
到後期他就整個都沒有辦法睡覺 06:34
然後他整個都沒有辦法睡覺的時候 06:37
他也會呈現一種盜汗 06:39
就是一直流汗 06:41
然後體重一直變瘦的情況 06:42
那最終呢 06:44
就是一直直到他死亡 06:45
所以 06:47
我們就從這種 06:48
家族性致死失眠症 06:48
你就可以看到 06:50
跟我們剛剛講的動物實驗 06:51
會有很類似的情況 06:53
就是你沒有睡覺 06:54
到最後 06:55
你就會呈現一個熱量失衡的情況 06:56
好 那這就是為什麼 06:59
我會跟你說 07:00
為什麼要睡覺 07:01
因為我們白天 07:03
其實是做非常非常多的工作 07:04
那當你做了這麼多工作以後 07:07
你總要有時間 07:09
讓你整個系統 07:10
然後讓它做一個重整 07:11
那健康 07:13
或者是我們剛剛講的熱量平衡 07:14
這個大概是 07:15
最基本的 07:17
就是跟生存相關的 07:18
那其他 07:20
其實也有一些比較細部的 07:21
比如說我們大腦在白天的時候 07:23
你不斷地在動腦 07:26
我們大腦用掉能量 07:27
會產生一些代謝物 07:29
那代謝物累積在你的大腦當中 07:30
久了以後 07:32
你的大腦就越來越髒 07:32
所以我們在睡眠當中 07:34
你就會最有效率的 07:37
把你白天產生的這些代謝物 07:38
把它清掉 07:40
所以想像起來 07:41
它就很像是 07:43
你在很忙的時候 07:44
你的工作室 07:45
你的房間 07:46
你的辦公室就會很亂 07:47
那等到這段時間終於忙完了 07:48
那就好好的把它打掃 07:50
打掃得乾淨一點 07:52
那乾淨一點 07:53
你的工作效率就會好 07:54
那我們的大腦 07:56
其實就類似這種機制 07:56
你白天就是把它弄亂 07:58
那晚上的時候 08:00
好好的把它打掃 08:01
那打掃乾淨以後 08:02
你隔天 08:03
你才能夠最有效率的啟動 08:04
所以剛剛講的這兩個 08:07
大概就是 08:08
我們可以用來理解 08:09
為什麼一定要睡眠的一個主要原因 08:11
就生存的機制來講 08:14
它是一個幫助我們維生 08:16
必要的一個條件 08:18
就是一個行為 08:20
那就我們的 08:22
比如說高效能 08:23
就我們的認知 08:24
就我們的情緒來講 08:25
它都有助於讓我們白天的 08:26
這一些所有的行為 08:29
做一個重整 08:30
我通常都會說 08:32
你就想像以前 08:33
你用以前舊的那個Windows 08:35
用久了以後 08:37
你是不是會變得越來越慢 08:37
系統會越來越卡 08:39
那這個時候怎麼辦 08:40
你就重開機 08:42
不是要什麼磁碟重組嗎 08:43
我記得以前都 08:44
這個也類似 08:45
磁碟重組通常是 08:46
什麼清理 08:48
反正就是把一些什麼 08:49
Cookie那些清掉 08:50
08:51
那這個就有一點類似 08:52
我們在談記憶系統 08:53
我們在睡覺的時候 08:55
大腦就會把白天的記憶 08:57
它判斷需要的記憶留下來 08:59
不要的記憶刪掉 09:01
然後再跟過往的記憶去做結合 09:03
那這個就有一點類似 09:06
你講的磁碟重組 09:07
雖然一剛開始我回答你說 09:09
不睡覺會怎麼樣 09:11
會死 09:12
聽起來好像很嚴重 09:12
但確實 09:14
如果我們從演化學來看 09:15
你就會發現 09:16
所有的生物都會睡覺 09:17
所有 09:19
連單細胞 09:20
不好意思 09:21
我必須要修正 09:22
植物 09:23
你知道嗎 09:25
我以前啊 09:25
我在寫論文的時候 09:26
我就曾經寫過這一句 09:28
那一樣 09:30
你就很像是我的指導教授 09:30
我的指導教授就盯我說 09:32
所有 09:33
你能證明所有嗎 09:34
好啦 大部分 09:36
我剛剛自己就一直非常想要問 09:37
是多原始的生物開始 09:40
感覺是比較複雜的才會睡覺 09:43
這個我們又要提到 09:46
蟲會睡覺嗎 09:47
睡覺它是什麼概念 09:48
比方說果蠅好了 09:50
你覺得果蠅會睡覺嗎 09:52
這個問法聽起來就是會 09:54
但是果蠅的睡覺 09:57
其實跟我們 09:58
現在所認知的睡覺不太一樣 09:59
因為我們現在在談 10:01
比較核心在談睡眠功能 10:03
是從哺乳類以後 10:05
那在這之前 10:07
我們會說它有接近睡眠的行為 10:09
比方說我們怎麼知道 10:12
這隻果蠅在睡覺 10:13
好那理想上 10:14
果蠅如果停在一個地方 10:16
那你稍微震動 10:18
如果牠清醒 稍微震動 10:20
牠應該會趕快飛走 10:22
那正常情況來講 10:23
果蠅不會停在一個地方停很久 10:25
所以研究者就會判斷說 10:27
在一天24小時紀錄當中 10:29
牠在白天的時候 10:32
那牠如果明顯的就是活動量比較多 10:33
晚上的時候活動量比較少 10:36
那稍微震動 牠都不太動 10:38
好 那我們就判斷 10:40
牠不太動的那個時期 10:41
就類似是睡眠的狀態 10:43
你剛剛提到比如說藍綠藻 10:46
10:48
藍綠藻這種會不會睡覺 10:48
這又牽涉到我們剛剛講 10:50
其實果蠅那種行為 10:52
我們可以把它理解成是一種生理時鐘 10:54
就是生物體 10:57
大部分的生物體 10:58
都必須要有這一種 11:00
它固定要活動的週期 11:01
跟它比較不活動的週期 11:04
那藍綠藻那些原生的藻類 11:06
它其實也有一天24小時 11:08
這樣子的週期 11:10
其實不要講藍綠藻 11:11
在好像2019吧 11:12
諾貝爾生醫獎 11:14
他所探討出來 11:15
在我們的分子層次 11:18
它其實就帶有這種 11:20
一天24小時的循環 11:21
在我們人類的細胞當中 11:23
在我們現存 11:25
可見的大部分的生物 11:26
它多半都帶有這種 11:28
24小時一個週期變化的一個現象 11:31
而這個現象的背後 11:34
多半是有一部分是活動 11:35
有一部分是休息 11:38
那休息的部分呢 11:39
很明顯的大休息那一種 11:41
我們就會把它理解成 11:43
類似人類睡眠的行為 11:44
那我想問一下 11:47
因為剛剛講說 11:48
大休息的那種 11:50
可是 11:51
我人生中有兩次的事件 11:52
讓我去接觸到了一種 11:55
就是比較奇怪的睡眠心態 11:56
一個是我大學的時候 11:59
因為我那時候就覺得說 12:00
睡眠很煩 12:01
我是一個超級需要睡眠的人 12:03
我怎麼樣睡都睡不飽 12:05
然後我覺得 12:06
它有點在浪費我的時間 12:08
因為我想要有更多的時間 12:09
可以做更多的事情 12:11
所以那個時候 12:12
有個學長他就跟我講說 12:13
有個東西叫超人睡眠法 12:14
超人睡眠法就是說 12:16
我們平常不是午休那樣趴15分鐘 12:17
就會覺得超有精神嗎 12:19
它就是把 12:21
你一日所需要的睡眠 12:22
拆成15分鐘15分鐘15分鐘 12:24
然後 12:26
變成一種 12:27
沒有一段超長時間的睡眠 12:29
但是 12:31
好像我記得是 12:32
整天你只要睡兩個小時吧 12:33
你只要固定時間睡15分鐘 12:35
然後再起來 12:37
然後再睡15分鐘 12:38
因為它的道理是說 12:38
有些生物也是這樣 12:40
並不是每個生物都是晚上 12:42
睡很長一段時間 12:44
然後我想問的是 12:46
真的是這樣嗎 12:47
因為我人生第二次碰到 12:48
非常類似的經驗 12:51
就是在我生小孩之後 12:52
小孩的週期就是 12:54
三四個小時喝一次奶加睡覺嘛 12:56
然後你就等到他下一次起來 12:58
喝奶睡覺 13:00
所以那個時候不只是小孩 13:00
是按照這個週期 13:02
父母也會跟著變成這個週期 13:04
有點類似 13:07
父母不會變成這個週期 13:08
父母只會很痛苦 13:10
13:11
父母只會很痛苦 13:12
好 那其實你講的就是 13:13
睡眠的另外一個 13:16
很容易被錯誤理解的一個概念 13:17
這個通常都忽略了睡眠 13:20
另外一個特性 13:21
就是我們剛剛講的生理時鐘 13:22
在我們的生物體當中 13:24
睡眠這件事情 13:26
是由兩個主要因素來決定 13:27
第一個就是你的睡眠壓力 13:30
我們通常會說睡眠債務 13:32
比方說你如果24小時沒睡覺 13:34
你的債務就很大 13:36
你壓力就很大 13:37
那大家都會覺得說 13:38
好 那我只要把壓力清除掉就好了 13:40
你剛剛講的這種分階段的睡眠 13:42
它就是著重在壓力這個部分 13:44
但是另外生理時鐘的意思是說 13:47
我們的生物體 13:50
你要在對的時間 13:51
做符合那個時段的行為 13:53
它才會最佳效率 13:55
以人類來講 13:56
因為人類是日行性動物 13:57
那日行性動物 13:59
牠的型態就是白天活動 14:00
晚上休息 14:02
也就是說如果我們人類 14:04
以這樣子的形式 14:05
去進行你的行為 14:07
它的效率會最好 14:08
如果我們從這個角度 14:11
演化的角度去思考的話 14:13
你就可以理解 14:15
睡覺這件事情放在晚上 14:16
它的執行會最有效率 14:18
那假設今天有一個作息正常的人 14:20
比方說你 14:22
你的作息還是大部分 14:24
你的生理時鐘還是晚上應該要睡覺 14:25
但是你在某一天 14:28
你就強制 14:30
你在白天的時候睡八個小時 14:31
那這樣子白天的八個小時 14:34
可以抵掉你晚上的八個小時嗎 14:35
不行 14:37
因為生理時鐘的關係 14:38
你在白天雖然同樣睡八個小時 14:40
可是你的睡眠結構 14:42
會跟晚上做這件事情不太一樣 14:44
你白天小睡一下 14:47
可以幫你恢復精神嗎 14:49
可以 14:51
但是長期下來 14:51
它可以讓你維持這樣子的一個狀態 14:53
然後你的大腦跟你的身心 14:56
不會受到影響嗎 14:58
目前的結論是不行 15:00
就如果你是一般人 15:02
目前的結論不行 15:03
你剛剛講的那一種 15:05
其實還有一些 15:06
在特殊情境的 15:08
比方說國外他們有一些在做 15:09
他要單人帆船 15:12
然後可能跨越大西洋 15:14
他們可能要一個人 15:16
然後開著船 15:18
然後可能開 15:19
可能要上百天 15:20
他必須要時時的醒著 15:22
不然他什麼時候撞上冰山不知道 15:24
那在這種比賽當中 15:26
他們就有過 15:28
有曾經採用你剛剛講那種方法 15:29
他就是把一天分成二十分鐘 15:32
二十分鐘當中 15:34
他可能小睡個一段時間 15:35
然後再醒來 15:37
那這個的確可以幫助他撐過比賽 15:38
但不適合一輩子都這樣 15:41
15:43
那上岸以後他可以繼續這樣嗎 15:43
不行 15:45
因為從那一些相關的研究發現 15:45
他的睡眠壓力一直持續在累積 15:48
所以他仍然需要補眠 15:50
那我可以問說 15:52
就是為什麼會講說 15:53
我們白天的時候醒著 15:56
跟晚上的時候睡覺是最有效率的 15:57
15:59
就是單純因為太陽本身 15:59
16:02
如果最核心來講 16:02
應該是我們日行性動物設計的機制 16:04
它本來就這樣 16:07
太陽這件事情 16:08
它對我們人類來講 16:09
對日行性動物來講 16:11
有一種促醒的效果 16:12
也就是說 16:14
只要你早上起來 16:15
你有照到太陽 16:16
它就可以幫你變得比較清醒 16:17
而這個主觀上的比較清醒 16:19
會讓你認知功能執行上會比較好 16:20
所以比方說你前一天晚上熬夜 16:23
那你早上起來昏昏沉沉的 16:26
但是你又要立刻工作怎麼辦 16:27
你就出去曬太陽 16:29
曬太陽可以讓你立刻醒過來 16:31
然後讓你的注意力趕快的回復 16:33
這個是 16:36
陽光對我們人類直接的效果 16:37
因為我周遭有一些人 16:40
他們就會日夜顛倒 16:43
通常比較藝術 16:44
就是那種創作家 16:45
或是表演類型的人 16:46
都是晚上表演嘛 16:48
所以他白天大概都在睡覺 16:48
然後晚上起來工作 16:50
這些人他們長久以來 16:51
這樣子的作息 16:53
會對他們的身體造成什麼影響 16:55
這個其實又要連結到 16:57
我們在談生理時鐘的時候 16:59
原則上在目前的研究裡面 17:01
生理時鐘的結論是 17:03
你如果可以維持穩定的作息的話 17:06
那基本上就是OK的 17:08
因為 17:11
工業革命以來 17:12
電燈普及了 17:13
然後現在所有的科技 17:15
都讓我們的環境 17:16
沒有那麼的絕對的白天跟晚上 17:18
所以在這種情況底下 17:21
現在的研究者主要 17:23
你可以把它想成退而求其次 17:25
就至少你要達到穩定 17:28
穩定就像你剛剛講的 17:30
如果他是一個長期是晚睡晚起 17:31
那他只要維持這樣子的節奏 17:35
就是比如說他可能三天晚睡晚起 17:37
然後三天變成一般的狀態 17:40
這樣就混亂 17:43
就有點像輪班工作 17:44
所以只要穩定的話 17:45
基本上 17:47
目前的共識是 17:47
對身體不會有太大的影響 17:49
但老實說在真實的情況底下 17:52
你要維持這樣子的一個作息 17:55
不容易啦 17:57
持續夜班的 17:58
就很像是你剛剛講的那種情況 17:59
但是他們仍然會碰到一種情況就是 18:01
我的家庭生活要顧啊 18:03
我的小孩是白天活動的啊 18:05
那我要不要帶小孩出去 18:07
那我要不要跟親友聯繫 18:09
所以他還是會需要跟那一些一般 18:11
就是白天醒來 18:14
晚上睡覺的人互動嘛 18:16
所以他還是會有幾天是不符合 18:18
他所謂的晚睡晚起的情況 18:21
我剛剛想到還有另外一個例子 18:24
可能就是像那種航空人員 18:26
然後他們要一直調時差 18:29
一直調時差 18:30
所以這個是一個 18:31
對身體不太好的作息吧 18:33
不用吧 18:36
一定是 18:36
一定是 18:37
我的博士論文就是研究生理時鐘 18:39
那我博士論文研究完之後的結論就是 18:42
盡可能不要做輪班工作 18:45
但是也不是這樣啊 18:48
因為我們現在的社會啊 18:49
你說沒有輪班工作已經不可能了 18:51
所以通常我會跟大家講 18:53
輪班工作不要一直做太久 18:55
研究的數據大概是這樣 18:58
如果你現在處於輪班工作的狀態 19:00
就是你生理時鐘混亂嘛 19:03
那麼你罹患各種疾病 19:04
這裡各種疾病 19:06
你想像到的疾病都有 19:07
高血壓 糖尿病 心血管疾病 19:09
中風等等通通有 19:11
那你罹患這些疾病的風險會上升 19:12
但是 19:16
如果你做了二十年 19:17
做二十年輪班 19:19
那接下來而我不輪班了 19:20
我變成正常的情況 19:22
那麼它的風險會再降低 19:24
也就是說人類至少 19:25
在比較年輕的時候 19:28
我們對於這種 19:29
違反我們天性的情況 19:31
有一定程度的耐受性啦 19:33
但是請記得 19:36
它畢竟是違反我們的基因的設計 19:37
所以你持續下去的話 19:41
風險會持續地上升 19:42
你有觀察到有什麼樣的年紀 19:44
就差不多可以開始停了嗎 19:45
像博恩你年輕的時候 19:49
你也可以很長時間 19:51
熬夜不睡覺 19:53
沒錯 19:54
不會怎麼樣 19:54
我已經不行了啊 19:55
對啊 19:56
我以前也可以啊 19:56
但是現在不行啊 19:57
所以 19:59
大概依照我這種耐受的感覺 20:00
我覺得大概三十五歲以後 20:03
它會明顯的 20:05
沒有辦法承受的情況會明顯的增加 20:06
所以我多半也會說 20:09
好啦 20:11
那你如果真的要輪班的話 20:11
還是切一段時間 20:13
那至少之後你真的要做的話 20:15
盡量去找固定的某一個班次 20:18
比較好 20:21
對 國外研究其實也發現 20:22
固定大夜班會比那種照三班輪的 20:24
他們的身體的健康 20:27
還是有比較好一點 20:28
20:30
我為什麼會那麼清楚知道 20:31
我現在已經沒有辦法那樣做 20:33
就是因為我以前在做夜夜秀的時候 20:34
我那時候的確是養成了另外一個 20:36
還算穩定的規則 20:39
對 但是它跟一般人不太一樣 20:41
我那時候四十八小時只睡一次 20:44
所以就是 20:46
因為我寫不完 20:49
東西太多 20:50
要看的東西太多 20:51
然後寫的東西太多 20:52
所以就每兩天睡一次 20:53
然後我那個時候有意外的 20:55
我想要確認這件事情 20:58
就是我突然發現說 20:59
我長期睡眠剝奪之後 21:02
不知道為什麼 21:04
我的心情變得比較愉悅 21:05
很奇怪 21:08
因為很反直覺 21:08
我都會 21:09
以前學的全部都是 21:10
睡眠剝奪一定會心情越來越不好 21:11
但我那時候有一個 21:13
好像置之死地而後生的一種愉悅 21:15
那我就去查 21:17
我那時候Google 21:18
sleep deprivation induced euphoria 21:19
然後還真的有查到結果 21:22
21:23
然後我那時候嚇死 21:24
可是像 21:25
最近幾年 21:27
那種健身啊 21:28
或是他們族群 21:29
比較流行的一種 21:32
長時間斷食 21:33
就是過往大家也覺得 21:35
每天都要吃東西 21:36
沒有人可以連續五天七天以上 21:37
不吃東西的 21:40
可是後來有研究說 21:41
喔你如果有一個長時間的斷食 21:42
它之後對於恢復身體機能這些 21:45
是有幫助的 21:47
所以我想要問的問題是 21:48
會不會其實也有這種 21:50
就是你長時間睡眠剝奪 21:52
然後你之後身體反而知道 21:54
我可以更有效率的利用睡眠 21:56
有這種現象嗎 21:59
欸我覺得這個想法很好欸 22:00
對嘛 22:02
22:04
我先補充你剛剛講的 22:04
就是 22:06
缺乏睡眠會不會讓你比較愉悅 22:07
有一種 22:10
對特定重度憂鬱症的治療法 22:11
就是睡眠剝奪 22:13
就是有一群那種重度憂鬱症 22:15
他吃藥也沒有效 22:17
做什麼東西也沒有效 22:18
那叫他不要睡覺 22:19
他就會產生類似的效果 22:21
但是 22:23
他只要再睡回去 22:24
他的憂鬱的程度又會回來 22:25
那至於長時間不睡覺 22:27
為什麼會有這種情況呢 22:28
第一個他不是每一個人都會這樣 22:30
就是有一類 22:33
有一類的情況他會這樣 22:34
一個可能的原因是你的大腦會 22:36
越來越 arousal 22:38
就是他會越來越清醒 22:39
而這個越來越清醒 22:41
就會讓你更多的控制感 22:43
然後你可以做越來越多的事 22:45
特別是那些事也會給你正向感受 22:47
比方說你那個時候在寫劇本 22:50
那你長時間不睡覺 22:53
然後越寫越起勁 22:54
要進入心流狀態 22:55
然後他寫完又有成就感 22:57
22:59
整個你就覺得爽 23:00
這個其實也是在一些藝術家 23:02
他們特有 23:05
為什麼晚上會處於這種 23:06
就是一直要熬夜這種情況 23:08
那我以前我在做研究的時候 23:10
我曾經想過一種假設是 23:12
當你一定程度的熬夜之後 23:14
你的大腦有沒有可能會變得比較有創意呢 23:17
這個其實是其中一種 23:20
其中一種觀點 23:22
因為 23:23
我們在研究創意這件事情上 23:24
它核心就是你要離開 23:26
你原本的框架 23:28
你要打破它 23:30
可是當你的大腦長時間不睡覺的話 23:31
它是 23:34
生理上已經在failing 23:35
23:37
所以你不得不離開框架 23:37
這個叫崩解 23:39
然後你就會處於一種 23:40
23:42
天馬行空 23:42
甚至如果你更長時間的話 23:43
其實是有可能會產生一些妄想或幻覺 23:46
妄想或幻覺聽起來是比較嚴重 23:49
但是你可以把它理解成 23:51
你會比較容易出現 23:53
一些原本不會有的 23:55
那種想法或感覺 23:57
但我要再次強調 23:59
這不是每個人都會有 24:00
就是有一些人會有這種情況 24:01
所以你就可以把它理解成 24:03
像你剛剛講的 24:05
好 那我晚上我不睡覺 24:06
我可以不受打擾 24:08
我會進入心流 24:10
而且我寫劇本又會特別來勁 24:11
所以它就會成為很多人說 24:15
我必須要熬夜才能完成 24:17
的其中一個可能性 24:19
大家應該都有個經驗 24:21
假如說期末考週 24:22
然後我們就熬夜念很多書 24:23
然後一考完所有科目的那一刻 24:24
睡特別沉 24:27
不是忘了 24:28
哈哈哈哈 24:29
就忘了 24:30
好老師喔 24:31
這是老師才有的 24:33
學生 我們才不在乎忘了或是記得 24:34
反正考完了嘛 24:36
對對對 24:37
就是睡 24:37
之後睡的那一覺很舒服 24:39
對啊 24:42
這個就是睡眠壓力 24:43
對啊 24:44
因為你長時間沒有睡覺 24:45
我們身體會累積睡眠壓力 24:47
睡眠壓力在我們大腦當中 24:49
我們有一個指標叫 24:51
adenosine 24:52
我們中文大概叫腺苷 24:53
也就是說 24:55
如果你持續不睡覺 24:55
你的腺苷的累積會越來越多 24:57
那當你腺苷累積越來越多 24:59
就會形成你的睡眠壓力 25:01
而你睡眠壓力越高的話 25:02
你進入睡眠當中 25:04
所謂的深層睡眠 25:05
它就會越長 25:07
而且會越深 25:08
通常我們在評估深層睡眠 25:09
會有兩個指標 25:11
一個指標就是 25:12
你的深層睡眠持續時間多久 25:13
就是量 25:15
那另外一個指標 25:16
就是我們可以去測量他的腦波 25:17
如果他那個腦波 慢波的 25:19
N amplitude 25:22
就是他的振幅越大 25:22
那也表示他的品質 25:24
深層睡眠的品質就會越好 25:26
所以當你的睡眠壓力越大的話 25:28
通常質跟量 25:31
他都會展現出 25:33
比較偏向深層睡眠 25:35
所以睡不好的人就是不夠累嗎 25:37
這個 25:39
也可以算是 25:40
他其中一個可能性 25:42
對 但是就像我們剛剛講的 25:45
其實影響睡眠的因素 25:47
他其實蠻多的 25:48
對 我剛剛 25:50
這個其實是我最在乎的一個點 25:51
我覺得啦 25:53
我好像 25:54
一直以來都有一種 25:56
我不管睡多久 25:57
都會有一種沒充好電的感覺 25:58
就像那個手機 26:00
然後插了一整晚 26:01
沒充到電 26:02
然後 26:04
我最近有個小故事 26:05
就是我最近動了一個手術 26:07
所以我需要全身麻醉 26:09
然後全身麻醉的時候 26:11
我睡得好爽哦 26:12
從來沒有 26:14
好久沒有睡得那麼爽 26:14
然後反正我在動手術的時候 26:16
我好像還在打呼 26:17
邊動手術 26:19
因為我太太有在旁邊幫我錄影 26:19
然後 26:22
打呼超大聲這樣 26:23
因為的確有錄影 26:26
所以 26:27
我聽得到醫生 26:27
跟我老婆在那邊碎嘴 26:28
醫生就說 26:30
他平常就這樣 26:31
然後我老婆說對啊吵死了 26:32
這個應該是 26:33
那個 可以去買一個 26:35
那個鎮壓呼吸器 26:36
感覺他平常睡眠 26:38
應該是都沒有到品質很好 26:39
然後 26:41
以前其實我一直在講說 26:42
我睡不好睡不好 26:44
其他人給我的建議 26:45
也是好像可以去測試一下 26:47
有沒有呼吸中止 26:48
這個其實 26:50
就是現在我們最多人 26:51
會有的一個問題 26:53
就是你睡覺的時候如果會打呼 26:55
而且很大聲 26:56
然後偶爾還會出現 26:58
好像他打呼打到一半中斷這種 26:59
這種我們通常都會建議 27:01
要去做一些診斷 27:03
但是你剛剛講的那個麻醉的部分 27:05
我想要再補充一下 27:07
其實有一些研究 27:09
他其實就透過深度麻醉 27:10
來模擬我們的深層睡眠 27:12
因為適當 27:15
這個跟麻醉藥的劑量 27:16
還有它的成分有關係 27:18
就是特定的麻醉藥的劑量跟成分 27:19
可以造成我們的腦波 27:22
類似 slow wave 的狀態 27:24
所以有一些動物實驗 27:27
他是用這個 麻醉來替代說 27:28
如果生物體進入睡眠狀態的話 27:32
牠會是什麼樣子 27:34
像曾經有一個研究 27:36
你可能應該聽過 27:38
他會說側睡對我們睡眠比較好 27:39
我只有聽說側睡不會打呼 27:43
對側睡比較不會打呼沒有錯 27:45
好那側睡對睡眠比較好 27:47
他背後的理論是用動物實驗 27:49
讓動物進入麻醉狀態 27:52
然後他去測量牠大腦清洗的狀態 27:54
就是把那些代謝物清掉的狀態 27:57
然後發現側睡的麻醉狀態底下 27:59
牠的清除的效率會比較好 28:03
所以就有一些說法說 28:05
好啦 那這樣子我們人都應該要側睡 28:07
但其實不是這樣 28:10
28:11
那回來一點就是 28:11
有一些人會誤以為把麻醉當成是睡眠 28:14
像是有一些人會去一些醫美診所 28:18
然後叫他幫他打那種 28:23
那種安眠 28:25
可以這樣喔 28:26
當然不行啊 28:27
但是你也知道這個世界就是 28:29
有一些不行但是有一些人行 28:30
實際上是不合法的 28:34
但是確實有人會這麼做 28:35
國外其實也有 28:37
好那這種情況他就會出現 28:39
一來他會有一種成癮性 28:41
因為那些麻醉藥 28:43
都是我們的神經類的藥物 28:44
那二來那一些會讓你造成那種 28:46
深度失去意識的狀態 28:49
其實你剛描述的又有一種 28:52
我們對睡眠很有趣的感覺 28:55
你想想看 28:57
其實人類真的並不知道 28:58
睡覺以後是什麼感覺 29:00
對是醒來之後的評估 29:02
所以我們總是覺得 29:04
如果我失去意識 29:05
我完全失去意識 29:06
那表示我睡得很好 29:08
對啊 29:10
對吧所以你剛講了 29:11
你進入麻醉狀態 29:12
雖然你的腦波也有slow wave 29:14
但是你就覺得 29:16
我有一段時間完全失去意識 29:16
好爽 29:18
他很像睡覺的感覺 29:19
但其實不是 29:21
我只是要跟大家說明 29:22
千萬不要用這種手法 29:24
以為你好像真的有睡覺 29:26
其實真的真的不是 29:27
可是我再舉手問一下 29:30
就是 29:31
一開始講到的那個家族 29:33
然後致命 29:35
對 致死失眠症 29:36
他們難道不能借助藥物 29:37
來讓他們睡著嗎 29:40
目前的情況是 29:41
因為他是大腦當中 29:43
掌管他睡眠清醒的系統 29:45
整個被破壞掉了 29:48
所以他就算是透過藥物 29:50
他大腦他仍然沒有辦法正常的運作 29:52
當然也可以 29:55
你剛講的那種情況 29:56
就有點像是緩解啦 29:57
但是他的損害的情況 29:59
一定會越來越嚴重 30:01
所以他後面走向同樣結局 30:03
其實是一樣的 30:06
就像我們做動物實驗 30:07
動物實驗比如說老鼠不睡覺 30:08
我們有沒有辦法讓牠延後 30:10
可以 30:12
我們讓牠吃高熱量的食物 30:12
高熱量的食物老鼠可以活久一點 30:14
因為我們剛剛講牠熱量會失衡 30:16
會一直變瘦 30:18
所以你只要給牠吃高熱量的食物 30:19
他會活得比較久 30:21
這個也很有趣 30:21
因為跟大家熬夜的經驗超像的 30:22
就是熬夜到一半就會肚子超餓 30:24
會很想吃東西 30:27
其實我們一定程度 30:28
你也可以把睡眠 30:29
或是沒有睡覺這件事情 30:30
看成是一種壓力 30:32
我們演化上 30:34
當你承受壓力的時候 30:35
你會做幾個動作 30:36
第一個當然就是你要累積能量 30:38
所以你晚上本來應該要休息了 30:40
可是你卻沒有在休息 30:42
就有一定程度會警覺說 30:44
是不是有敵人要打過來 30:46
所以我要儲備能量 30:48
所以可以吃的時候 30:49
我當然盡量吃 30:50
研究也發現你在吃宵夜的時候 30:51
你會特別喜歡選高熱量的 30:53
跟平常相比 30:56
30:57
這個如果我們從剛剛講 30:58
那種演化上會判斷 30:59
這是處於壓力狀態 31:01
所以你要去選擇高熱量的 31:03
這樣聽起來就非常合理 31:05
所以我都會盡量讓自己不要太晚睡 31:07
因為你不要讓自己的大腦 31:10
陷入那一種錯誤的認知 31:13
對啊 31:15
你這樣子挑戰你的大腦 31:16
實在是太辛苦了 31:18
瞭解 31:19
因為剛剛講到腺苷 31:19
然後深層睡眠這些東西 31:21
我想要問的問題是 31:23
有哪些原因會讓我們 31:24
沒有辦法進入深層睡眠 31:26
像呼吸中止 31:28
它就是一個 31:30
肇因是什麼 31:31
就是 31:31
為什麼有些人會這樣 31:32
我們可以理解 31:34
我們睡眠還是有從淺到深 31:35
那從淺到深 31:38
除了你的大腦以外 31:39
你的肌肉會越來越放鬆 31:40
呼吸中止它的核心的原因 31:42
就是你的呼吸道會塞住 31:44
你仰躺的時候 31:47
你可能脖子這邊 31:48
或者是你呼吸道哪邊比較狹窄 31:50
因為你的肌肉張力放鬆了 31:52
所以它會塌下來 31:54
所以你可以想像我們的呼吸道 31:56
它本來是一個比較有彈性的管子 31:58
那等到晚上睡覺以後 32:02
它彈性可能變得比較差了 32:03
那上面會有一些重量 32:05
然後壓下來 32:07
因為你肌肉放鬆了 32:08
那壓下來 32:09
然後它就塞住了 32:10
我們的大腦 32:11
它比如說你剛開始睡覺的時候 32:13
還行 32:15
還沒有被塞住 32:16
慢慢越來越塞住 32:17
那一旦塞住了 32:19
你的血氧濃度會下降 32:20
那血氧濃度下降會死掉 32:22
所以你的大腦會把你喚醒 32:23
所以它就會形成是 32:25
你本來由淺到深 32:27
可是你深的時候就會塞住 32:28
所以你還沒到深的時候 32:30
大腦就會把你喚醒 32:31
那喚醒你就會再回到淺 32:33
然後淺再深 32:34
然後再喚醒 32:35
所以那些嚴重的 32:37
睡眠呼吸中止的 32:38
他就會幾乎沒有深層睡眠 32:40
那幾乎沒有深層睡眠 32:43
所造成的影響會非常非常的大 32:45
所以在臨床研究也發現 32:48
如果那一種睡眠呼吸中止的個案 32:50
他在罹患各種慢性疾病的風險 32:54
我要再重述一次 32:57
中風 心血管疾病 糖尿病 高血壓 32:58
只要你想像得到的那些慢性的疾病 33:01
它在睡眠呼吸中止的個案 33:04
都會明顯地上升 33:05
所以我們通常 33:07
如果我去演講的對象 33:09
是40歲以上 男性 肥胖 33:11
只要綜合這三個 33:14
我們就會說 33:16
你評估一下晚上會不會打呼 33:16
會不會很大聲 33:18
等一下 肥胖跟 33:19
是因為剛剛講的所有的熱量調節 33:21
所以他逐漸地會開始變胖 33:24
因為有一種塞住的 33:26
是因為比如說他的脖子 33:28
他可能比較多脂肪 33:30
那躺著你也可以想像 33:33
他就整個壓下去 33:34
然後就會塞住 33:36
在面對男性的場合 33:37
我們比較會談這件事情 33:39
等一下 33:41
我剛剛聽到一個關鍵 33:42
那女性呢 33:43
女性不打呼的 33:44
她在睡眠呼吸中止的風險上 33:45
她確實是明顯的比較低 33:48
是老天性別歧視還是什麼原因 33:50
曾經有一些說法是 33:52
雌性素的關係啦 33:55
但這個我之後沒有update 33:57
所以不太確定 34:00
我當時讀書的時候 34:02
我看到一種說法 34:03
雌性素在身體 34:04
確實在很多的層面上 34:06
對女性有一些保護 34:08
那也看到了 34:09
女性的更年期過後 34:11
她的很多的風險 34:14
其實也會提高 34:16
這個是當時我所理解到的一個說法 34:18
但現在的研究走到那裡 34:20
我不太知道 34:22
因為關於性別的荷爾蒙 34:23
我只有在讀書的時候有研究而已 34:25
瞭解瞭解 34:27
那我剛還有聽到一個關鍵詞是 34:28
腺苷 34:29
我對這個詞的印象呢 34:30
跟咖啡有關 34:33
對對對對 34:34
果然是學Neuroscience的 34:35
我今天很想問 34:39
就是 34:40
各個會影響到睡眠的某些物質 34:41
像是咖啡 34:44
然後 34:46
其實以前 34:47
我對鎂沒有那麼 34:48
就是沒有看到那麼多的鎂 34:50
然後最近幾年 34:52
一大堆人叫我們要吃鎂 34:53
是什麼東西啊 34:56
為什麼啊 34:58
我也覺得現在好像每個人 34:59
都需要吃很多東西 35:02
除了鎂以外 35:04
還有什麼魚油啊 35:04
很多東西 35:06
好那第一個 35:07
腺苷這種東西 35:09
它是我們身體 35:10
你清醒的時候 35:12
大腦它就會自然產生 35:13
你可以把它看成一種代謝物 35:14
所以我們大腦在醒著的時候 35:16
它因為不斷的在運作嘛 35:19
所以它確實各種代謝物都有 35:21
而腺苷這種比較特別的是 35:24
它累積的越多 35:25
它就會促使你的大腦不想工作 35:27
促使你大腦罷工 35:29
就會想睡覺 35:30
而咖啡因 35:31
咖啡因本身它的結構式 35:32
就是跟腺苷很像 35:35
所以你如果喝咖啡下去 35:37
比方說你可能24小時沒有睡覺 35:39
所以你腺苷很多 35:41
那腺苷很多 35:43
腺苷必須要跟接受器結合 35:43
它才會產生睏睡的效果 35:45
那咖啡因你吃進去呢 35:48
它就會佔著毛坑不拉屎 35:49
它會跟腺苷的接收器結合 35:51
可是它不會產生作用 35:53
這就是為什麼咖啡因你喝下去 35:55
可以有一段時間讓你保持清醒的關係 35:57
這是最核心的要素啦 36:00
但是呢 36:03
你 咖啡因佔著毛坑不拉屎 36:04
可是腺苷還是一直在產生 36:06
一直在累積 36:08
所以如果你持續不睡覺的話 36:09
你的咖啡因必須要一直補一直補 36:11
因為咖啡因的半衰期 36:13
以正常人類來講的話 36:15
大概4到6小時 36:17
那它那個耐受性是怎樣 36:18
就是我們的受器會一直增加是嗎 36:20
腺苷的受器 36:22
腺苷會不斷地累積啦 36:24
那受器是固定的啊 36:25
可是 36:28
咖啡因佔住它的時間是固定的啊 36:28
它沒有辦法一直佔著 36:31
因為一段時間它就會消失 36:32
對 它有半衰期 36:35
它會被代謝掉 36:37
那為什麼大家會講說那種喝咖啡 36:38
然後會越喝越沒有效果 36:41
這個就跟耐受性有關 36:43
可是這個部分可能要牽涉到 36:45
咖啡因的學問 36:47
我以前啊 36:49
我在去一個就是在談咖啡的場合 36:50
談我們剛剛講的事情 36:54
那就有一位非常懂咖啡的人告訴我說 36:55
如果它是真正的好咖啡的話 36:59
它是不會影響睡眠的 37:03
那我當時就非常不能夠理解 37:05
什麼叫做真正的好咖啡 37:07
就我們剛剛理解的是 37:10
咖啡因本身的結構跟腺苷很像嘛 37:11
對不對 37:14
所以只要它是這種咖啡因的結構 37:15
它必然會產生影響 37:18
所以它的差別就是 37:19
這個咖啡的咖啡因的程度 37:21
37:24
多跟少的差別 37:25
那也的確不同的咖啡豆 37:26
然後它烘焙的不同的方法 37:28
它會影響到它的成分 37:30
所以我的理解是 37:32
有一些咖啡如果你適當地把它 37:33
把它煮出來的話 37:37
它的咖啡因可以比較少啦 37:38
這個是我的理解 37:40
那就是爛咖啡啊 37:41
我喝咖啡是為了醒的 37:43
而不是為了喝味道的 37:44
對 那這個就是看你需要咖啡 37:46
到底是需要咖啡因 37:49
還是需要咖啡的味道 37:50
那我如果為了睡得更沉 37:52
然後白天一直喝咖啡 37:56
來讓我在睡前剛好可以crash 37:57
就是身體垮掉 38:01
全部的腺苷湧進去 38:02
我是不是比較容易可以進入深層睡眠 38:04
其實我覺得這種方法沒有那麼 40:12
沒有那麼有效 40:15
就理論上 40:16
就理論上來講 40:17
還以為是沒有不行 40:18
其實與其這樣 40:20
不如你可以去做一些更簡單的 40:21
比如說你白天多一些活動 40:23
那另外一個就是你白天多一些照光 40:25
其實現代人很常忽略了陽光 40:28
對我們睡眠產生的效果 40:31
好那陽光的效果 40:34
第一個它可以讓我們的生理時鐘 40:36
比較穩定 40:37
剛剛我們講嘛 40:38
我們生物體它就是一個穩定 40:39
白天醒 晚上睡覺的這種型態 40:41
所以這種型態你只要越明顯 40:44
越明顯的意思是 40:47
比如說有一些上班族 40:48
他們在白天的時候都在建築物裡面 40:50
那他中午可能叫外送 40:53
那他下班的時候可能已經 40:55
天黑了或黃昏了 40:57
所以他 40:58
你就可以想像他一天 40:59
真的曬到陽光的時間就很短 41:00
像比如說我們現在攝影棚就很暗 41:02
只有這種攝影燈 41:05
所以你一天 41:07
如果都在這裡面拍攝的話 41:08
你今天照光就非常非常少 41:10
那相對的如果有人都是一天 41:13
比如說至少他在外面的時間 41:15
可能兩個小時以上 41:17
那這兩種人 41:19
他在白天所接受到的光線 41:20
陽光就不一樣 41:22
而不一樣就會影響到 41:24
他夜晚的褪黑激素的分泌 41:25
那褪黑激素你也可以理解 41:28
它就是幫助你比較容易啟動睡眠 41:29
的一種我們的神經激素 41:32
套用我們剛剛的說法 41:35
你白天只要有適度的照光 41:37
那幫助你的褪黑激素在晚上 41:39
比較容易分泌 41:41
那比較容易分泌 41:43
你就比較容易可以進入 41:44
我們剛剛講的 41:46
進入睡眠也好 41:47
或是進入比較深層的睡眠 41:48
所以我才會說與其你要用咖啡 41:50
那種方法 41:53
你不如去照光 41:54
它其實是一個更簡便的方法 41:56
褪黑激素我也是蠻好奇的 41:58
就是 42:00
因為臺灣沒有賣 42:00
臺灣有賣嗎 42:02
臺灣是處方箋 42:03
你必須要去找醫生 42:04
OK 42:05
可是如果從國外帶回來是OK的 42:06
好像是 42:10
我記得是 42:11
42:12
因為 42:13
基本上每次去美國 42:14
我就會買褪黑激素 42:15
42:17
那你吃了有效嗎 42:17
我吃了有效 42:18
很有效 42:19
可是我老婆吃了沒效 42:20
那你大概都什麼時候吃 42:21
就是睡前嗎 42:22
睡前吃嗎 42:24
其實一般來講 42:25
如果我們在 42:27
真的你在使用褪黑激素的話 42:29
多半是睡前的一個小時 42:30
它的使用時間會比 42:33
一般吃安眠藥更前面一點 42:34
對 因為褪黑激素 42:37
我們會把它看成是 42:38
它是讓你的身體知道現在是晚上了 42:40
所以它等於是一種間接的效果 42:43
它不是直接促進你睡眠 42:45
我們就可以想像 42:48
生物體 42:49
日行性動物睡覺是這樣 42:50
你要先知道現在是晚上了 42:51
那先知道現在是晚上了 42:53
慢慢慢慢放鬆 42:54
然後進入睡眠狀態 42:56
所以褪黑激素是讓你知道 42:57
現在是晚上了 42:59
就等於是睡眠的前奏曲 43:00
那安眠藥 43:03
它是直接作用在你大腦 43:04
跟入睡相關的那些機制 43:06
所以它就是睡覺前吃 43:08
所以這個也是我們不太會說 43:10
如果你失眠 43:13
除非你是那種 43:14
跟生理時鐘 時差等等的 43:16
這些有影響的人 43:18
不然不會直接建議吃褪黑激素 43:20
那另外沒有效的原因 43:23
比方說很多人 43:25
他可能是因為壓力的關係 43:26
這裡的壓力 43:28
沒有 我老婆應該沒有什麼壓力 43:29
但是另外一種就 43:30
那請問一下 43:33
老婆是會想太多的人嗎 43:35
應該不是 43:40
應該不是 43:41
那你觀察她最有可能是什麼 43:42
我覺得她動太少 43:45
那她晚上會使用3C嗎 43:46
43:49
電腦 電視 手機 43:49
對 電視 43:51
那這個我們可以再連結一下 43:53
剛剛我們談的生理時鐘跟照光 43:55
剛剛我們談白天照光 43:57
可以讓你的生理時鐘比較穩定 43:59
那另外還有一個就是白天照光 44:01
如果你照的時間比較長 44:04
然後強度比較高的話 44:07
它還有一個效果 44:08
它可以抵消你晚上使用3C 44:09
對褪黑激素抑制的效果 44:12
對 你也知道你晚上使用3C 44:15
這個光線會抑制你的褪黑激素 44:17
這個是本來就存在的一個抑制作用 44:19
而這個抑制作用 44:22
在人體上 44:23
它有一點是比較級的概念 44:24
也就是說如果你白天你照很強 44:28
而且相對時間比較多的光線的話 44:31
那你晚上受到這個手機的影響 44:35
就會比較小 44:38
因為你可以想像 44:38
你在戶外都是1萬 lux 以上 44:39
那你手機或者是室內的光線 44:42
大約是300到500 44:45
所以在這種情況底下 44:47
你整個人的生理時鐘 44:48
就會呈現相對穩定的狀態 44:50
你的褪黑激素抑制就會比較少 44:52
但是假設有一些人 44:55
他白天不太出門 44:56
所以不太照到光 44:57
那也不太活動 44:58
那他的生理時鐘 45:00
我們會說他是處於一種比較 45:01
不明顯 45:05
我們正常就是 45:06
你白天越活動越好 45:07
晚上越不活動越好 45:09
可是如果你白天跟晚上的活動 45:11
都差不多 45:13
那他生理時鐘不明顯 45:14
他的褪黑激素的分泌 45:15
就會比較平緩 45:17
所以這也是為什麼我們會推薦 45:19
就那一些長輩 45:22
因為有一些長輩 45:23
他可能也行動也不方便 45:24
但是就算你行動不方便 45:27
你在白天的時候 45:28
還是要出去照光 45:29
還是要有一些活動 45:31
因為這樣子讓你生理時鐘 45:32
呈現一個穩定的狀態 45:34
你晚上的睡眠 45:35
褪黑激素的分泌才會穩定 45:36
那照光有說照多久 45:38
或是 45:42
陰天怎麼辦 45:43
或是大太陽的話 45:44
我可以只照五分鐘嗎 45:45
對於生理時鐘穩定的建議的話 45:46
大概至少30分鐘 45:49
很久欸 45:51
30分鐘的光 45:52
你不用在太陽底下曝曬 45:53
比如說你可以撐傘 45:56
你可以在樹蔭底下 45:57
你可以在騎樓底下 45:58
接受到的光線 45:59
閃射嘛 46:00
因為光會閃射 46:01
你接受到的光 46:01
大概也都有上千至少上萬 lux 46:02
我們一般的辦公室的光線 46:05
如果我們辦公室有開日光燈的話 46:08
那大概也只有300-500 lux 而已 46:10
所以你就可以對比 46:13
它的強度的差異 46:14
其實非常大的 46:15
可是我們人類 46:17
其實對於500跟5000 lux的光強度 46:18
你沒有那麼明顯 46:22
你是 喔比較亮 46:23
但是你不會覺得它是十倍亮 46:24
所以現代人很多失眠的 46:26
其中一個要素就是 46:29
反正我一整天都有光 46:30
可是它的光是室內的這種人造光源 46:32
那人造光源跟太陽光源的頻段 46:35
又不太一樣 46:38
所以它對我們生理時鐘穩定的效果 46:39
就又會不太一樣 46:42
這個其實在之前 46:43
2020年疫情的時候比較明顯 46:45
因為疫情不能出門 46:47
就會變成是整天都關在家 46:49
然後那個時候疫情又有壓力 46:50
那又有這種生理時鐘的問題 46:53
所以當時睡不好的人 46:54
就非常非常多 46:56
運動對於睡眠來講是好的吧 46:57
非常好 47:01
截至目前為止 47:03
如果我出去外面講座 47:05
如果有人問說老師我睡不好 47:07
怎麼樣可以幫我睡好一點 47:09
那你也知道 47:11
其實睡不好的原因百百種 47:11
那目前為止 47:13
大概可以推薦的有兩種 47:15
一種就是運動 47:17
運動在各個項目上它的統合分析 47:18
然後各個 47:22
它大概的效果都是正面的 47:22
但是 47:24
它有一個前提 47:25
就最好是白天運動 47:26
套用我們剛剛講的 47:29
人類是自行性動物 47:30
所以你在白天運動是可以 47:32
剛好可以讓你的生理時鐘 47:34
變得更穩定更強健 47:36
那如果說 47:39
可是不行啊 47:40
我白天要上班啊 47:41
我只能晚上運動怎麼辦 47:42
那通常我們的建議是 47:44
有運動總比沒運動好 47:46
所以第一個 47:48
如果你真的只能晚上運動 47:48
還是要去運動 47:50
那第二個 47:51
最好可以讓你運動的時間 47:51
在你入睡時間前面的三小時 47:54
這個是來自於 47:57
因為我們運動 47:58
你會交感神經會運作 47:59
那你交感神經運作 48:01
變比較arousal的狀態 48:02
你需要有時間讓它降下來 48:03
所以這段時間距離你入睡時間越近 48:05
它對你睡眠的影響其實就會越大 48:08
那當然這又會跟年紀有關係 48:11
博恩你的聽眾應該比較多是年輕的 48:14
不見得 48:16
就是以我為中間的一個常態分佈 48:17
對對對 48:21
對 那比較年輕的 48:22
他們受這種影響 48:23
其實確實就會比較小 48:25
因為其實大家都年輕過 48:27
我以前念大學的時候 48:29
我們晚上十點才來練系隊 48:30
我們練完 48:32
我回去還可以睡覺 48:33
然後有很多人的說法是 48:35
你睡不著就不夠累 48:36
你趕快去運動 48:37
對 所以運動讓你比較疲累 48:38
然後你就會好睡 48:41
這樣子的一個觀點 48:43
如果要完全成立的話 48:45
它必須要在白天 48:46
如果它在晚上的話 48:48
它又會有其他的 48:49
比如說年齡的因素 48:51
你運動的強度 48:52
運動的時間等等 48:54
又會有其他的因素加進來 48:55
瞭解 48:57
我覺得有點連帶著 48:58
那個超人睡眠法 48:59
我超級在乎的是個體差異 49:00
因為我就會很忌妒 49:03
不太需要睡眠的人 49:04
然後 49:05
對啊 49:06
不是 49:07
我在這個世界上的時間已經夠短 49:08
為什麼要花三分之一的時間 49:10
在模擬死亡 49:12
就是 49:13
你有沒有想像過 49:14
如果有一天 49:15
我真的有一些科技的方法 49:16
讓你可以都不用睡覺 49:17
你覺得你很高興嗎 49:20
很高興啊 49:21
我要引用 49:23
名著 49:24
鋼之鍊金術師裡面 49:25
OK 49:26
等價交換 49:27
阿爾馮斯·愛力克 49:28
他所說的一句話 49:30
你有看過那一部嗎 49:31
49:32
因為他變成盔甲 49:33
不用睡覺嘛 49:34
他說 49:35
眾人皆睡我獨醒的時候 49:36
是非常悲傷 49:38
是非常孤獨 49:39
就是他晚上不用睡覺的時候 49:40
其實他是非常孤獨的 49:42
那真的是他的問題 49:43
很多事情可以做 49:46
好 他沒有短影音可以滑 49:48
所以你這麼說也是 49:51
49:54
那可不可以不用睡覺呢 49:54
其實這件事情 49:56
一直以來都有非常多的說法 49:57
我最近 49:59
我最近去一個地方演講的時候 50:00
那就有一位聽眾 50:03
那位聽眾 50:04
目視看起來好像是七十來歲 50:05
他跟我說 50:08
他一天只要睡十五分鐘 50:08
然後我說 50:10
真的嗎 50:11
你從小就這樣 50:12
對 他說他從小就睡得非常少 50:13
那其他認識他的人 50:15
也都現場附和 50:17
說他真的睡得很少 50:19
這個因為沒有辦法做實驗 50:21
所以不曉得 50:23
好 這是第一個例子 50:24
那第二個呢 50:25
那有沒有可能 50:26
有人真的睡得很少 50:27
那最接近有科學實證的是 50:29
有一些人 50:32
他擁有短眠基因 50:34
就是他真的不用睡那麼多 50:36
因為我們一般人 50:38
一天我們成年人 50:39
我們建議睡七到九小時 50:41
平均值八嘛 50:43
可是那一些擁有短眠基因的人 50:44
他們的平均值大約是五 50:46
也就是說他們的range 50:48
是從四到六 50:49
跟睡眠相關 50:51
有一個DEC2 50:52
這個基因呢 50:53
他就發現他們家族 50:54
如果遺傳在這個基因上 50:55
帶有變異的話 50:57
他們就真的不用睡很多 50:58
另外一個呢 51:01
這個基因一剛開始被發現的時候 51:02
有一些媒體稱它為 51:04
菁英基因 51:07
51:08
51:09
因為帶有這個基因變異 51:10
除了不用睡覺以外 51:11
除了不用睡覺以外 51:12
還有一個特色 51:13
就是他對於多工 51:15
會比較容易適應 51:17
就是你一方面講電話 51:19
一方面做別的事情 51:21
他在attention 的 switch上 51:22
就可能做得比較快 51:24
這是當時媒體的說法 51:26
那這種短眠基因 51:28
他後來的研究到目前為止 51:29
大概有四到五個不同的基因 51:32
都可以有類似的效果 51:34
可是呢 51:36
有沒有更短 51:36
到目前為止 51:38
科學實踐還沒有發現更短 51:39
就是真正從研究上操作出來的 51:40
在人類身上大約就是四到六 51:43
那這一些短眠基因的人 51:47
他們也都是從小 51:49
就是他都是睡得很少 51:50
那短眠基因的研究 51:53
目前以科技來講 51:54
它其實是非常重要的一環 51:56
因為第一個 51:58
我們人類隨著年紀的增加 51:59
我們的睡眠的效率會變差 52:03
那短眠基因 52:05
它可以呈現一種特色 52:06
就是 52:08
這一類的人 52:09
他的睡眠的效率 52:10
比一般的人還要更好 52:11
所以現在科學家就想要知道 52:13
那他到底整個的機制 52:15
是怎麼運作的 52:17
有沒有可能複製 52:19
現在動物實驗上可以複製 52:20
那如果可以的話 52:22
人類身上可不可以複製 52:23
對 所以這個是目前短眠基因 52:25
最想要操作的 52:27
我剛剛很想問一個問題 52:28
因為剛剛不是說 52:30
有個七十幾歲的老人 52:30
他一天只睡十五分鐘 52:32
可是我們 52:33
一般印象對老人 52:34
就是他們都沒有在睡覺 52:35
不是 52:38
因為老人 52:39
還是很早睡很早起 52:40
反正就是老人 52:43
有人活到越老 52:44
然後睡得越少的趨勢嗎 52:46
正常人來看的話 52:48
目前為止認為 52:50
老化對他睡眠時數 52:52
就是要睡多久這件事情 52:54
影響力也不大 52:55
現在國際的共識認為 52:57
就算你六十五歲以上 52:59
你一天至少也是要睡 53:01
七個小時左右 53:03
那為什麼會形成那種印象 53:04
第一個 53:06
因為當我們老化之後 53:07
我們夜晚的睡眠會提前 53:08
就是生理時鐘會往前跑一點 53:11
那第二個 53:14
我要修正一個說法 53:14
就是年紀比較大的人 53:16
那他維持長段睡眠的能力 53:18
會比較差 53:21
因為膀胱 53:22
53:23
應該說會有很多人會有聽過 53:23
就是 53:26
比如說 53:27
他可能十點睡 53:27
那他可能半夜 53:28
可能三點就會醒過來 53:29
就他不再像年輕的時候 53:32
可以一次睡滿八個小時 53:33
好 那這個其實是我們年老之後 53:35
對於睡眠長時間的這個能力變差了 53:39
但不是因為他不需要 53:42
所以也有一些研究會發現 53:44
你看那一些長輩 53:46
他雖然晚上可能睡很少 53:48
可是白天坐在那邊看電視 53:50
很容易就睡著 53:52
那白天坐在那邊看電視 53:53
很容易睡著 53:54
代表什麼 53:55
代表他睏睡度 53:55
他睡眠壓力是高的 53:56
我們以為長輩不用睡覺 53:59
可是他們是處於一種高度睏睡 54:00
就靜止下來容易睡著的狀態 54:03
所以並不是他們不需要 54:05
只是他們沒有辦法睡得那麼長而已 54:07
這個是我比較偏向是能力的衰減 54:11
因為我自己現在也是類似這種情況 54:14
我以前年輕的時候 54:18
也是可以一次睡上十個小時 54:19
可是現在我大概睡七個小時 54:21
甚至更短就會醒 54:23
我剛剛只是在想 54:26
會不會有可能是 54:27
因為年紀大了之後 54:29
睡眠自然減少 54:31
導致他們的能量失衡 54:33
然後人類才會慢慢的 54:34
邁向 54:36
但聽起來不是這樣 54:36
OK 54:38
那再回去問一下好了 54:38
就是研究那個短眠基因的人 54:40
然後他們身體 54:42
說不定有某一種機制 54:43
或他特別會合成某一種蛋白質 54:45
讓他可以清除廢物的效率比較高一點 54:48
那到時候如果我們發現 54:51
那個東西是什麼的話 54:52
會怎麼實際應用出來 54:53
該不會是吃某個補品 54:55
基因程式其實最有可能的是 54:57
透過基因編輯 55:00
去做調整 55:03
這個是我目前的想像 55:04
因為你也知道 55:07
現在有一些基因編輯的技術 55:08
所以如果假設 55:10
就是一百年後 55:11
我們真的定位了有哪幾個基因 55:12
是這個樣子 55:14
然後我們也真的可以 55:15
透過基因編輯去做的話 55:16
那麼這樣子的操作 55:18
也許是有可能 55:19
可是已經出生的人已經沒救 55:21
對不對 是只能那個受精卵 55:22
那就要看到時候 55:25
基因編輯的技術做到哪個程度了 55:26
我對基因的理解就是 55:29
你在成長過程當中 55:30
你仍然可以對基因 55:32
有一定程度的修改 55:34
這是目前表觀遺傳學的觀點 55:35
那到底這個修改可以到什麼程度 55:39
或者是我們那個基因編輯 55:42
可以到什麼程度 55:44
這個我就不清楚了 55:45
但照目前人類 55:47
我超想要的 55:49
不過我還是要說明 55:50
其實現在短眠基因的研究 55:51
其實還算很新 55:53
因為 55:54
我記得當時第一個研究 55:55
好像是2019年吧 55:57
那真的 55:59
也進展得很快 56:01
可是其實我們人類的科技 56:02
通常是這樣 56:04
你前面你會看見它的正面的效果 56:05
可是負面的效果 56:09
通常是一段時間以後才出現 56:10
所以到底它這樣修改了 56:13
那對我們人類個體的影響 56:15
或者是整體的影響 56:18
它會是什麼樣子 56:20
不知道 56:22
那我想要最後來聊一下夢好了 56:22
因為感覺夢是 56:26
睡眠裡面也會發生 56:27
但是另外一整個大分支 56:29
56:33
我們剛剛開錄前有閒聊一下 56:34
夢是有意義的嗎 56:36
這句話非常引戰 56:40
夢到底有沒有意義 56:43
這件事情 56:45
就我身為一個比較偏 56:45
腦科學家的觀點的話 56:48
啊就放電嘛 56:51
它可以有意義的方式在於 56:52
你對它的解讀 56:53
而不在於夢的本身 56:56
因為我們大腦本來就會對我們內在 56:58
過往的記憶 57:01
現在的記憶 57:03
它會有一些weighting 57:04
就是有一些對你比較重要的東西 57:06
它就會比較把它 57:08
記憶的連結做比較深刻 57:09
而在晚上做夢 57:11
夢這個行為 57:13
如果以腦科學來看的話 57:14
它是一種現象 57:16
而這個現象在於你的大腦特定的區域 57:18
被激發之後 57:21
特別是那種感覺聯合區 57:22
因為我們大腦側邊就是顳頂葉交界處 57:25
那你有一區就是把感覺 57:28
還有動作 57:30
還有跟你過往的記憶都會連結在一塊 57:32
那你晚上睡覺的時候 57:35
你這一區的腦區 57:36
它在特定的情況底下被激發了 57:38
也就是說 57:41
它就會連帶的激發很多 57:42
跟感覺 跟動作 感受 57:44
跟記憶相關的腦區 57:46
然後產生了所謂的夢境的感受 57:48
而這個夢境的感受 57:51
如果透過人來解讀的話 57:52
你可能會有一些insight 57:55
就是領悟說 57:57
原來它是因為這個樣子 57:58
因為 58:01
所謂的心理治療 58:02
或是所謂的意義這件事情 58:03
它有一個核心的要件是 58:06
你到底是不是接受它 58:08
等一下 58:09
可是我剛剛比較想要問的是 58:10
它在生理上的意義是什麼 58:11
夢是幫忙排除這個疑慮 58:13
還是幫忙鞏固 58:15
我舉個例子好了 58:17
我最近非常常做的惡夢 58:18
這真的喔 58:20
很常做這個惡夢喔 58:21
我會夢見我在戰場上 58:22
已經在打仗了 58:24
然後有一個子彈就這樣 58:25
打進我胸口 58:27
大家應該都有那種 58:29
就是事情快要完蛋的那種 58:30
就是全身失溫 58:32
然後完了完了完了 58:34
我要死在這裡 58:35
完了完了 58:37
我不想死 58:37
不想死 58:38
啪 就醒來 58:38
因為這是惡夢 58:40
重複做好幾次這個夢 58:42
PTSD 58:43
它為什麼要鞏固 58:45
或是 58:47
它好像也沒有在幫忙排除 58:47
它這個 58:50
有一種說法是 58:51
夢境它確實一定程度 58:53
是幫助我們去演練 58:55
演練你有可能會發生的 58:58
一個不好的經驗 59:00
或不好的事件 59:02
所以在夢中出現那種 59:04
比較危險的情況 59:06
另外一種說法就是 59:08
當你的這個負向的經驗 59:09
就是這個情緒的經驗 59:12
或是你累積所產生出來的 59:14
這個經驗過於強大的時候 59:15
它就會卡在那邊 59:17
然後持續地停在那裡 59:19
幾年前就是有一個研究 59:22
他說這一類會重複出現夢境的人 59:24
他大腦當中晚上的時候 59:27
他關於腎上腺素的分泌 59:29
他還是會呈現一個 59:31
比較沒有停止的狀態 59:33
因為我們大腦當中的腎上腺素 59:35
它在晚上的時候應該是靜止的 59:38
特別是在速眼動睡眠的時候 59:39
它應該是幾乎沒有 59:41
可是這一類的人 59:43
他在晚上的時候 59:44
還是會一定程度的分泌 59:45
也就是說你的大腦應該要放鬆 59:48
你的大腦應該要忘掉 59:50
你需要戰爭 59:52
需要逃跑那個東西 59:53
但它仍然存在 59:55
我覺得這很有趣 59:56
因為從小到大 59:57
就我會覺得我很少做夢 59:59
但每當我做夢一定是惡夢 00:00
我幾乎沒有做過好夢 00:03
然後都是這種緊張的 00:04
比如說那個學生時期 00:06
會一直做一個夢就是 00:08
那個考試寫不完 00:10
然後就要交卷 00:12
然後考得很爛 00:13
這個是我超常做這個惡夢 00:14
幾乎到我畢業之後 00:16
5、6、7、8年 00:19
我還在做這個惡夢 00:20
那個trauma 00:21
對 這個創傷經驗很強 00:23
這個也是非常多學霸 00:25
特有的那種成長後的創傷經驗 00:26
其實我們要再釐清一下 00:29
其實你說的是你記得的夢 00:30
因為做的夢跟記得的夢 00:34
其實兩回事 00:35
我們在晚上 00:36
你大概會有4到5次的速眼動睡眠 00:37
那研究會發現你大概 00:40
只要在速眼動睡眠當中喚醒 00:42
你大概會有70%到80%的夢 00:44
換句話說 人一個晚上 00:47
平均應該會有3到4次的夢 00:49
所以差別是你記得或不記得 00:52
那為什麼你會記得呢 00:54
那其中一個原因是 00:56
你做完夢之後你醒過來 00:58
所以你才記得 01:00
那為什麼會醒過來呢 01:01
一個部分就是 01:03
那是你的最後一個夢 01:04
就是因為你會越來越接近凌晨 01:06
那最後一個夢呢 01:09
它在我們整個睡眠結構當中 01:11
還有一個特色 01:13
就是 01:14
你越接近睡眠後半的夢境 01:14
它的情緒性會越強 01:17
然後它的劇情會越詭異 01:20
會越奇怪 01:22
所以 01:24
多半如果你是在 01:25
比較後期所做的夢 01:27
然後它的情緒張力又高的話 01:28
你醒過來就比較容易記得 01:30
回應你剛剛那個問題的話 01:32
比較簡單的回答是 01:35
你不是沒有做好夢 01:36
只是好夢沒有強到讓你記起來 01:37
為什麼我不能做一個很強烈的好夢 01:40
對 這就是人類非常辛苦的地方 01:43
跟我們整個生物體的機制有關 01:46
因為生物體本來就是對負向的事件 01:48
他會比較關注嘛 01:51
因為負向跟生存有關係 01:53
你做春夢跟你生存沒關係 01:55
做春夢只是讓你爽而已 01:57
但是做壞的夢 01:59
那些生存相關的夢 02:01
跟你活下來是有關的 02:02
所以我覺得很多東西 02:04
都是朝向這樣子的機制去設計 02:06
所以當你在睡眠當中 02:08
負向的情緒越強烈 02:10
它其實一定程度會影響到你的生理 02:13
就比方說你在夢中被打到了 02:15
然後其實你的心跳 02:18
真的心跳就會變快 02:19
你看過那個全面啟動 02:21
全面啟動當中講的 02:23
你在夢中的人如果被打到了 02:25
或者是你在夢中真的掛了 02:27
那你真的人也會掛 02:30
這個其實是一定程度的 02:31
你的生理跟你的夢境會有連結 02:33
對 所以在這種情況底下 02:36
負向經驗情緒很強的 02:38
它就容易讓你arousal 02:40
那arousal就是容易讓你醒來 02:42
你醒來你就會記得 02:44
那關於那種全人類 02:45
幾乎大家都共同有做過的夢 02:47
就是心理學上面是怎麼去解釋 02:51
比如說什麼從很高的地方一直掉落 02:54
欸 有做過這個夢嗎 02:56
應該說這一類的夢境 02:58
在海裡面游泳 03:00
然後醒來就尿床 03:01
這種 03:03
海裡面尿床 03:05
最好是只有我 03:06
有做這些夢 03:07
你們沒有從很高的地方 03:09
一直掉一直掉一直掉 03:11
很少 03:13
我很少啦 03:13
應該說如果以人的經驗去詮釋的話 03:14
他好像也多半會跟他的壓力 03:18
跟他最近所產生的整個不平衡 03:21
生活上的不平衡有關 03:25
那至於你剛剛講的在海裡面游泳 03:27
然後尿床這件事情 03:30
這個其實跟我們前面講的 03:32
你在夢中的生理感受 03:34
會連結你的夢境 03:37
對啊 03:39
因為當你膀胱越來越滿的時候 03:40
你的身體會給你一個訊息 03:42
跟水相關的訊息 03:44
跟想尿尿相關的訊息 03:46
所以這個訊息一定程度的 03:47
會進入到你的夢境 03:49
然後他在夢中尿下去了 03:50
他真正的床上也尿下去了 03:52
對 所以這個比較偏向是 03:54
你真正的身體的這個生理訊號 03:56
然後進入到夢中 04:00
而這個其實也有一些研究 04:01
是外在的環境 04:03
他也可以進入夢中 04:05
比方說曾經有一個研究 04:07
他會讓人在那邊睡覺 04:08
然後就偵測他進入速眼動睡眠 04:10
然後就在他的臉上灑水 04:12
就用那種花灑 04:14
就霧霧的那一種灑水 04:16
然後他就發現 04:18
如果他這麼操作的話 04:19
大約42%的人 04:20
你把他喚醒 04:23
就掃完水一段時間把他喚醒 04:24
問他說你剛做什麼夢 04:26
他會說他夢中有水這個元素 04:27
就很像是比方說 04:30
我本來夢到我在跟博恩錄音 04:32
那突然不曉得為什麼 04:34
那個攝影棚就噴水 04:36
就是 04:38
本來的夢境裡面是沒水的 04:39
但是當你做這個操作以後 04:41
水的元素會跑進去 04:43
這也跟全面啟動那部電影類似 04:44
所以 04:46
這個其實是現在有一些的 04:47
關於夢境的研究 04:50
知道內外在的訊息 04:51
會影響到夢境的內容 04:53
那也有人會用這種方法去操作 04:55
就你剛剛不是說嗎 04:58
我很想要做好夢 04:59
那也有一些說法是說 05:00
有特定的音樂 05:03
塞巧克力給他吃 05:05
巧克力 05:08
睡眠的時候可能不容易 05:09
因為睡眠的時候操作比較多 05:12
會用氣味跟用聲音 05:14
那有一些說法是特定的音樂 05:16
在速眼動睡眠播放 05:19
它透過這個音樂進入你的夢中 05:21
比較容易讓你做好夢 05:23
但是這個目前為止還沒有共識 05:24
就研究上沒有共識 05:28
比較多的是商業上的說法 05:29
而這個說法你聽起來 05:31
好像也是make sense 05:34
因為音樂會進入夢中 05:35
聲音會進入夢中 05:37
只是 05:38
它對我們所謂的好夢的影響力 05:39
有沒有那麼大 05:41
這個可能又是另外一個issue 05:42
我先問一個問題 05:45
然後再問一個連帶 05:47
可能比較有爭議性的問題 05:48
就是我有一個朋友 05:50
然後他好像跑去讀 05:52
應該是弗洛伊德跟夢有關的東西 05:54
好像有讀到說 05:56
這個夢它發生的 05:58
都是比較淺層的 06:02
也就是說 06:04
需要用到比較複雜推理 06:05
或是條件子句這種概念 06:08
不會出現在夢裡面 06:11
你不會做一個夢 06:12
然後比如說 06:13
假如明天怎麼樣 06:14
我就會怎麼樣 06:16
沒有這種情形 06:17
我說喔是嗎 06:18
然後我回去觀察了一陣子 06:19
然後就發現說 06:22
欸沒有啊 06:22
我的夢裡面還是有這種假設語氣啊 06:23
可是我很好奇的是 06:26
我們現在所知 06:27
夢它牽扯到的腦區 06:29
是不是真的是比較低認知的 06:30
曾經有一個研究是這樣 06:33
它讓人睡覺之後 06:35
然後用特定頻率的腦波 06:37
就穿顱磁刺激的方法 06:40
然後也是一樣打在那個 06:42
大概是頂葉跟顳葉交界處 06:44
就我們剛剛講的 06:47
感覺動作聯合區這個地方 06:48
然後透過頻率的刺激的話 06:50
它可以讓你產生夢境的感受 06:51
而且不管你在哪一個睡眠階段 06:54
你在速眼動睡眠也可以 06:56
你在非速眼動睡眠 06:57
我只要打下去 06:59
你就會出現夢境的感受 06:59
你也可以想像 07:01
如果你單純打在這個地方的話 07:02
它確實它是跟那一些記憶啦 07:04
感覺啦 07:07
動覺相關 07:08
那另外你剛剛講的那些邏輯推理 07:10
這個多半在前額葉嘛 07:13
那有一些研究的確也發現 07:15
夢境當中呢 07:17
主要會活躍的一個 07:18
就是我們剛剛講的 07:21
比較頂葉跟顳葉交界處這個地方 07:22
那有一些人他的前額葉 07:24
也會稍微活躍 07:26
那前額葉如果你越活躍的話 07:27
其實你對於 07:29
剛剛我們講的邏輯推理 07:31
然後甚至是自我認知 07:32
它相較之下就會比較強嘛 07:34
那關於這個我就要提 07:36
有一種比較特別的夢境 07:38
清明夢 07:39
Lucid Dream 07:40
你曾經在夢中知道 07:41
你自己正在做夢的嗎 07:43
是是是 07:44
曾經有 07:45
有有 07:45
對 那有一些研究 07:46
他就是想要知道 07:47
在夢中知道自己在做夢 07:49
跟夢中不知道自己在做夢的差別是什麼 07:51
那他的結論就是 07:53
那一些在夢中他做清明夢的人 07:55
他的前額葉會明顯的比較活躍 07:58
當然顳頂葉交界處這個地方也是 08:00
那如果用比較簡單的版本來說明的話 08:03
你之所以會做清明夢 08:06
就是你的大腦前額葉 08:08
跟某一些特定做夢的腦區 08:09
比一般人還要活躍 08:11
那相反的來講就是 08:13
你該放鬆的腦區沒有放鬆 08:15
所以你就比較會在夢中 08:18
可以知道自己在做夢 08:20
甚至你可以控制你的夢境 08:22
對 因為高階的可以控制夢境 08:24
甚至你可以夢中夢 08:26
夢中夢這個議題 08:27
連結我們回去說 08:29
那個比如說以榮格或弗洛伊德的角度 08:30
夢有沒有意義 08:33
那我就很想知道 08:34
你所謂的夢有沒有意義 08:35
是包含哪一種夢呢 08:37
你不知道自己正在做夢的夢 08:39
跟你知道自己做夢的夢 08:41
那你知道自己做夢的夢又有分 08:44
你知道自己正在做夢 08:47
但是你可不可以控制 08:48
08:49
如果你可以控制的話 08:50
你可以控制的夢境是有意義的嗎 08:52
那還叫夢嗎 08:54
08:56
那感覺你已經醒了 08:56
夢中夢到底哪一個夢才有意義呢 08:58
那還有我們剛剛有講 09:01
我們從外在的訊息 09:02
可以影響你的夢境內容 09:04
對不對 09:05
好那如果你是被影響了 09:06
那這個夢是有意義的嗎 09:08
你應該要怎麼解讀 09:09
對 所以這個就是從神經科學的角度 09:11
我們可以看到夢的很多不同的面向 09:14
夢的展現它有非常多元的形式 09:17
也許 09:20
也許某一些 09:20
我們透過清醒之後的解讀 09:22
它確實展現了潛意識的某一些層面 09:24
但是其他是不是都有 09:28
就我現在的觀點來講 09:30
如果我們現在這麼多的操作方法 09:32
通通放進去的話 09:33
它其實就是一個 09:34
很難說它有意義的程度 09:36
好那 09:38
再講另外一個 09:39
做夢的科學的研究者 09:40
他們也實際要定義過 09:42
什麼叫做夢 09:44
他們定義是什麼 09:46
比方說 大家覺得 09:47
如果你在睡覺的時候 09:48
你有飄過一個畫面 09:50
那這個畫面飄過去大概只有兩三秒 09:52
靜止的畫面 09:55
這是夢嗎 09:56
不是 09:58
對嘛 09:58
那如果有一個意念飄過去 09:59
這是夢嗎 10:01
應該不是 10:02
那如果夢中你感受你經歷了一件事 10:02
但是沒有很強烈的情緒 10:06
就是比如說你在夢中寫字 10:07
你也沒有畫面 10:10
你就感覺到你有在寫字 10:11
這算夢嗎 10:13
應該算 10:13
到底什麼樣的感受才叫夢 10:14
所以最後有一群做夢的科學家 10:18
他們的定義是這樣 10:22
夢境當中 10:24
你必須要有一定程度的情緒 10:25
然後它的劇情必須要有一點怪誕 10:28
或者是在明顯的現實的情境 10:31
就是你不能只有什麼意念飄過去 10:35
畫面飄過去 10:37
這個通通不算 10:38
10:39
好啦那我講這個 10:40
其實也是想要讓大家知道 10:41
睡眠當中 10:44
你出現的那些類似 10:46
意識表現的那些現象 10:48
它其實不是只有做夢跟沒做夢 10:51
沒有這麼單一 10:54
它更像會是一個頻譜 10:55
就是有一些很複雜的 10:58
它可能有強烈的情緒 10:59
怪誕的劇情 11:01
但是往這邊一點 11:03
它可能是普通的劇情 11:04
沒什麼情緒 11:05
再往這邊一點 11:06
它可能就單純只有畫面 11:07
再往這邊一點 11:09
它可能就只有一個意念 11:10
所以 11:12
你所謂的夢境到底要切在哪邊 11:13
那它才算有意義 11:16
我自己目前的觀點是這樣 11:17
如果是那一種 11:20
你自然發生的夢境 11:21
然後你醒來還記得 11:23
甚至是你剛剛講 11:25
有會重複出現的意義 11:26
我認為這個對我們人來講 11:29
它確實是有重要性的 11:31
夢境就很像是一剛開始大腦 11:33
你可能隨意激發 11:35
那隨意激發當中 11:37
可能就有一些線索連結到 11:38
你可能過往或是你當下 11:40
最近這段時間一些重要的經驗 11:42
或重要的情緒經驗 11:45
然後它被激發出來 11:46
它的程度又強烈到 11:48
會讓你清醒過來還記得 11:50
我會把它解讀成 11:53
這樣子的一個情緒經驗或記憶 11:54
對我這個人 11:57
對我大腦而言 11:58
它是判斷它的重要性是高的 11:59
我試著去解讀 12:02
記憶背後跟我最近的生活 12:04
跟我過去的生命脈絡有什麼關係 12:06
那如果我可以正確地去評估出來 12:09
我可能就會知道說 12:11
喔原來 12:12
有什麼事情 12:14
我的意識可能一直試著要去忽略它 12:15
那如果真的 12:18
可以給我這樣子的提醒的話 12:19
那我就會說 12:21
喔好 12:22
那我的潛意識告訴我 12:22
我應該要這麼做 12:24
所以我願意 12:25
去聽從我的insight 12:26
請注意這個insight 12:29
仍然是你解讀出來的insight 12:30
我願意聽從我解讀出來的insight 12:32
去做一些改變 12:34
好吧 我只是覺得 12:36
因為剛剛有強調說 12:37
它仍然是經過你自行解讀 12:38
之後的一層意義 12:41
所以對我來講 12:42
這個刺激 12:43
就跟任何你聽到一首歌 12:44
或是你看到 12:45
就假如說你聽到一個歌 12:46
那歌詞寫到你心裡面去 12:47
然後說 12:49
我從來不知道我這麼重視這件事情 12:50
它的意義好像跟夢的意義 12:51
對我來講是一樣的 12:53
不會一樣 12:54
因為夢是你產生的 12:55
好吧 12:57
因為確實你聽到歌 12:58
你會有一些insight 13:01
就因為這個歌 13:02
可能牽動了你的某一個記憶 13:03
或牽動了你某一個感受 13:05
所以你才會出現 13:07
剛剛你說的那個感動 13:08
或者是insight 13:09
那夢境它跟歌不一樣的地方是 13:10
它比較像是你的大腦 13:13
所出現的這個訊息 13:15
它不是你可以控制的訊息 13:17
但是是你產生的 13:19
所以我們人自然而然 13:20
會對於我產生的 13:22
這個內在的訊息 13:24
會比較願意相信 13:26
瞭解 13:28
不過我最近有一個兒子的小故事 13:30
我也覺得 13:31
假如說你內心很單純 13:32
然後你也很 13:34
誠實地面對 13:35
你喜歡跟不喜歡什麼東西的話 13:36
這個夢的解讀好像也 13:37
不是那麼需要 13:38
反正我兒子他最近 13:40
會開始做夢了 13:41
我很驚訝 13:42
就是他三歲 13:43
然後他會做夢 13:44
他會記得夢 13:45
他也會敘述他做什麼夢給我聽 13:46
然後他最近有一次醒來 13:48
他就說 13:49
爸爸我剛做夢 13:50
我夢到 13:51
你帶我去7-11 13:52
然後你買糖果給我吃 13:53
然後我想說 13:54
ok 13:55
的確是做夢 13:56
就是他很清楚 13:57
他喜歡吃糖果 13:59
他的慾望 14:00
14:01
他想要我帶他去7-11 14:01
夢境的內容都是記憶 14:04
而記憶就會牽涉到幾點 14:06
就是他有沒有可能被誘導 14:08
或是他有沒有可能 14:10
因為我當下的某一些 14:11
想望 14:14
我想要的東西 14:15
而去 14:16
修改他的夢境 14:17
所以當然我覺得 14:19
孩子在很純真的底下 14:20
他不會有這種 14:21
他比較不會有這種情況 14:23
他可能更多的是 14:25
忠實地去轉述他夢境的內容 14:26
可是如果放在成人的話 14:29
其實你在清醒時候 14:30
你接觸到的訊息 14:33
或者是 14:34
別人給你的誘導 14:35
他一定程度的 14:36
就會影響到你的夢境 14:37
其實在這邊 14:39
我想要表達的是 14:40
做夢境的研究 14:41
其實老實說 14:42
真的非常的困難 14:43
因為他跟你的記憶好不好有關係 14:45
他跟你的表達能力好不好有關係 14:48
表達能力好的人 14:51
他就可以講了很多 14:52
所以這一切都是 14:54
我們在談所謂的夢 14:56
到底有沒有意義 14:57
以及夢要怎麼研究 14:59
等等等等的 15:00
我覺得目前都還非常 15:01
困難的一個地方 15:04
是不是就放著就好了 15:05
就不要去探索 15:06
對啊 15:07
因為這很難 15:07
可是你知道嗎 15:09
其實在我開始學心理學之後 15:09
我自己的一個觀點是 15:12
夢是解開人類心智能力的 15:14
最後一塊拼圖 15:17
你不覺得現在大部分的心理科學 15:19
都研究清醒 15:21
清醒的意識狀態 15:22
對不對 15:24
那後來從睡眠科學開始展開以後 15:25
我們也知道睡眠的時候 15:27
你大腦也有一些運作 15:30
而你睡覺的時候 15:31
這些運作會回過來 15:32
影響你白天的心智功能 15:34
可是睡眠的時候 15:37
又有一個很特殊的情境 15:38
就是夢境 15:40
夢境到底算不算意識呢 15:42
當然這我們可以有很多的討論 15:44
但至少你的所謂的夢境的展現 15:46
是我們心智的一個 15:48
很特別的一種表現方法 15:50
而這個表現方法 15:53
到底為什麼要這樣子 15:54
為什麼沒有被演化掉 15:55
如果從演化學的角度 15:57
我們說必然有它的功能 15:59
那它的功能到底是什麼 16:00
那目前為止都還非常的未知 16:02
雖然有一些功能論的說法 16:05
但是還是很難 16:08
就是整個涵蓋說 16:09
為什麼我們仍然有這些現象 16:11
所以我一直覺得 16:13
如果我們人類的研究 16:15
一直到我們可以解開 16:17
夢境的秘密的話 16:18
那個時候我們對於整個人類的心智 16:20
應該也是差不多都瞭解了 16:22
因為夢的秘密實在太困難了 16:25
像那個Space的Final Frontier 16:28
這個夢是人類意識的 16:31
Final Frontier這樣 16:33
還有一個問題 16:34
我不是問說 16:35
那個運動對於睡眠來講很重要 16:36
然後你說出去外面 16:38
基本上會給兩個建議 16:40
給睡眠的 16:41
然後一個是運動 16:42
另外一個是什麼 16:43
你居然還記得這件事情 16:44
對啊 16:45
我要再為你鼓掌 16:45
覺得 欸 16:46
呵呵 16:47
另外一個其實就是類似 16:49
Mindfulness 16:50
那樣子的練習 16:51
就是正念 16:52
或是靜坐或禪修或瑜伽 16:53
這一類的 16:55
這一類的練習 16:56
16:57
因為這主要是來自於現在很多人 16:58
我還以為會是什麼 17:01
那個什麼均衡飲食這種 17:01
不是 17:03
是Mindfulness 17:04
其實均衡飲食多半是 17:04
我是預設大家營養上 17:06
沒有什麼太大的差異啦 17:09
在這個前提底下 17:11
我們多半會給類似 17:13
Mindfulness的建議 17:15
這個其實主要是來自於現代人 17:16
在晚上的時候其實不太會放鬆 17:19
因為晚上你還是一樣在照光 17:22
還是一樣在看3C產品 17:24
所以理想上我們正常的夜晚 17:27
應該要像那個農耕時代 17:31
就晚上的時候光就很弱 17:34
然後你幾乎就不會動腦 17:36
但是我們現代人到現在 17:38
我們的大腦是幾乎醒著的時候 17:40
都是持續運作的 17:42
那久了以後它會形成一種慣性 17:44
就是你的大腦會覺得 17:46
只要醒著你就要一直工作 17:48
一直工作一直工作 17:50
那就會有一種 17:51
類似忘了 17:53
或是不知道什麼狀態 17:54
才是放鬆的狀態 17:56
那久了以後它會不利於入睡 17:58
那入睡我們會說 18:01
你必須要在睡覺前 18:03
你的大腦 18:05
如果簡化的說法就是 18:06
你的大腦要放鬆 18:08
可是你這個慣性一旦形成 18:09
你的大腦就不容易放鬆 18:11
那不容易放鬆你就不容易入睡 18:13
所以目前對於靜坐或Mindfulness 18:15
或類似這種相關的研究都發現 18:18
你透過這種練習 18:21
可以讓你的大腦比較容易關機 18:22
那這個部分我要再補充一下 18:26
其實 18:28
我們大腦當中 18:29
關於睡眠這件事情 18:30
其實很多人會覺得說 18:31
我們大腦當中有一個開關 18:33
而這個開關呢 18:35
打開你就清醒 18:36
關掉你就睡覺 18:38
但其實不是 18:39
我們的機制是有兩個開關 18:41
一個開關是管清醒 18:44
一個開關是管睡眠 18:46
所以 18:48
理想情況是 18:49
比如這邊清醒這邊睡眠 18:51
白天的時候清醒程度比較高 18:52
清醒打開 18:54
睡眠的就要關掉 18:55
那等到你慢慢慢慢越來越久以後 18:57
你清醒的要越來越往下 19:00
越來越關掉 19:02
那睡眠的越來越打開 19:03
所以等到晚上睡覺前 19:05
睡眠的完全打開 19:07
清醒的完全關閉 19:08
所以你就很好的睡覺 19:10
對不對 19:11
那我們剛剛描述的那種情況就是 19:11
你白天的時候清醒的時候打開 19:14
對不對 19:15
那你隨著你的清醒時間越來越長 19:16
你睡眠壓力越來越多 19:18
所以你睡眠系統打開了 19:19
可是你清醒的部分沒有降下來 19:21
或是降的不夠多 19:23
那在這種情況底下 19:25
它就會變成是你不容易入睡 19:26
那這也是現代人 19:29
失眠最大宗的一種情況 19:30
這個是其中一種問題 19:33
那再結合另外一個就是 19:34
當你睡不好的時候 19:36
你會做什麼行為來幫助你入睡 19:38
那這個就會分軌 19:42
分軌的意思是 19:44
如果你做的是正確的行為 19:45
它就會幫助你回復 19:47
但是如果你做的是錯誤的行為 19:48
它就會讓你睡得越來越不好 19:50
我可以想像所有人都是滑手機 19:53
哈哈哈哈 19:54
對 但講到滑手機啊 19:57
其實 19:58
你也很難一言以蔽之說 19:59
滑手機或3C絕對不好 20:01
你知道前一陣子 20:03
我讀過一個研究 20:04
就是 20:05
對特定族群來講 20:06
睡覺前30分鐘看一點電視 20:08
對他們來講有助於睡眠 20:11
哪一類人呢 20:13
就是他是白天大腦就持續運轉 20:15
高速運轉的人 20:18
那你就可以想像 20:20
對那種人來講 20:21
他在看電視 20:22
看那些比如無腦的劇 20:24
那他就會覺得說 20:26
這個對我來講就是放鬆 20:27
所以它其實仍然是一種相對的 20:29
你有一個刺激可以幫助他 20:32
不要想那麼多 20:35
然後只在那邊看無腦劇 20:36
所以對他來講 20:39
他仍然是比較可以放鬆 20:40
可是呢 20:42
你如果就整個機制來講 20:43
它並不是最好的放鬆方法 20:45
只是對那一些人來講 20:47
他還是放鬆 20:49
那如果你可以學會更深層的 20:50
就像我們剛剛講的 20:52
靜坐啦 禪修啦 瑜伽啦 20:53
Mindfulness 等等的 20:55
這些都是更深度的睡眠 20:57
如果你可以透過練習 20:59
可以掌握這種方法的話 21:01
那你睡覺前的這個清醒的開關 21:02
就比較容易關掉 21:05
那比較容易關掉之後 21:06
你再把那一些生理時鐘啊 21:08
睡眠壓力啊 21:10
這個都調節好 21:11
你的睡眠就比較容易展開 21:12
所以現代人的失眠的問題 21:14
你要說是壓力嗎 21:17
也的確是壓力 21:18
但是呢 21:19
壓力之後 21:20
你的處理方法 21:21
有沒有朝向正確的方向 21:23
這個才是大部分 21:25
在做失眠認知行為治療 21:27
最關鍵的地方 21:29
所以 21:30
我們常常聽到說 21:31
你就看電視就好啊 21:31
運動就好啊 21:33
什麼什麼就好 21:34
那因為每一個人 21:35
在睡眠這個因素當中 21:37
他出錯的地方就不太一樣 21:40
所以你很難有 21:42
一言以蔽之的方法啦 21:44
我可以想像某些東西 21:45
對睡眠是有幫助的 21:47
比如說 21:49
那個窗簾真的要全暗 21:51
或是燈要全部關起來這樣子 21:52
因為光我很明顯的知道 21:54
跟睡眠有關 21:55
可是我看到你寫的是一篇文章 21:56
就是說 21:59
溫度也會影響 22:01
22:03
高溫 22:03
22:04
我看到之後我就覺得說 22:05
哇 那個 22:06
在那邊強調說什麼 22:07
現在冷氣要開26 27 22:08
胡說八道 22:10
睡不好啊 22:13
這個又會戰起來 22:13
誰在乎地球啊 22:15
我要睡覺 22:16
其實跟我們的溫度調節是有關係的 22:17
我們的體溫往下降 22:20
這裡指的體溫是核心的體溫 22:21
核心的體溫往下降 22:24
它也會讓你比較容易產生睡意 22:25
所以換句話說 22:29
你當然在一個比你的體溫 22:30
還要低溫的環境 22:33
那會幫助你體溫往下降 22:35
那個定義很廣 22:37
這樣只要37度以下就算好睡 22:39
但是可以影響到我們的核心體溫的 22:41
通常要更低 22:46
那研究是這樣 22:48
我們有的時候會看到有一些 22:49
引用西方國家研究的 22:51
他們會說大概18度 22:53
但是其實 22:56
22:57
你就可以知道18度 22:57
對我們臺灣人來講 22:58
超冷 23:00
23:01
所以後來的 23:01
一直尿尿 23:02
後來的一些研究 23:03
我自己的解讀是這樣 23:05
這會需要看你這一個人 23:07
本來生活的環境 23:09
我們以前教書的學校當中 23:11
有一個日本的教授 23:13
然後他的辦公室超冷 23:15
我每次進他辦公室 23:18
我說你不會冷 23:19
然後他穿短袖 23:21
這樣剛剛好 23:22
對 所以不同國家他們生活的 23:24
本來的環境 23:26
就會影響到我們剛剛講的 23:27
最適睡眠的溫度 23:30
那些西方國家有一些研究出來 23:33
是大概18度左右 23:35
不過我後來也有看到有一些 23:36
在亞洲國家的 23:38
比如說中國的 23:40
然後馬來西亞他們的研究 23:42
其實大約是大概23度 23:43
不錯 23:46
對 但是最佳是不是23度 23:46
那你也知道 23:49
其實所有的行為科學的研究 23:50
都是找一批人 23:52
然後來做 23:53
那找的人多半是成年人 23:54
就是年輕人 23:56
所以你這樣子23度 23:58
是適用在所有人嗎 24:00
其實很難說 24:02
所以多半我們給的建議是 24:03
那一個環境 24:05
第一個就是你的溫度 24:06
你要覺得涼爽 24:08
舒適 24:09
然後溼度不要高 24:10
那因為溼度高 24:12
你的散熱就會變得比較不容易 24:14
所以在這種情境底下 24:16
你的入睡是比較容易展開的 24:18
那如果過冷 24:20
像比方說我如果在18度 24:21
我一定會覺得超冷 24:23
在那種情況底下 24:25
就會比較不好睡 24:26
瞭解 24:28
今天非常感謝 24:29
宇哲老師分享這麼多 24:30
很有趣的 24:31
有夢的 24:32
有生理的 24:32
如何入睡的 24:33
也有些最實用的 24:34
就是正念 24:35
運動 24:37
24:37
冷氣可以調冷一點點 24:38
我個人最喜歡 24:41
今天再次非常非常感謝宇哲老師 24:42
謝謝 24:44
那今天這集博音錄到這邊 24:45
vs 中間沒有點 24:46
我們下集再見 24:47
掰掰 24:48

Lyrics & Translation

[English]
Hello, all listeners
Welcome to listen to the latest episode of Boyin
I don’t know if you are listening now
in the morning or at night
Are you getting ready to go to sleep
or just got up
But I don’t feel enough sleep
I want to talk about the topic of this episode today
I am personally very interested
and I am also deeply troubled by it
It is almost a lifelong theme
That is sleep
Then we invite the webmaster of Wowsai Psychology
We are here to welcome teacher Cai Yuzhe
Hello Bo En
Hello everyone, listeners
I am Yuzhe
I am very happy to be here
I can come and talk to you about sleep again
In fact, is this what I want to talk about in today’s episode?
We can chat for a very, very, very long time
Yes, because basically we are on the topic of sleep
We have held a 36-hour workshop
Yes
It depends on how long we want
We can chat for as long as we want
Okay, then I will first
address some of my personal questions
Then there may be some wild questions
and then ask for advice
Have you seen similar phenomena in academic circles?
The first thing I am very confused about is
Why do we need to sleep?
Why do we need to sleep?
If we talk about organisms,
the simplest way to say it is
If you don’t sleep, you will die. Because a sleep researcher who just started doing research
...
...
...
...
also wanted to know this question very much
But you can't do experiments on people
What should I do
Just use mice
So let the mice
stay awake all the time
The study found that under normal circumstances
he would take about four to six weeks
and the mice would die
In addition, death
What is the cause of death?
At the beginning, researchers also thought that
if it was because of the heart,
the heart would have lesions.
Then lesions would appear in other places.
So they wanted to know
exactly where
lack of sleep would cause problems.
What was the result?
There is no consistent answer.
In other words, what?
There may be some cardiovascular problems
There may be other local problems
But they will not all point to where
The last study
He found that ultimately
you can have a more clear answer is
In the later stage
his caloric regulation became unbalanced
Simply speaking, these mice
will eat twice as much as usual
That is, he eats a lot
but his weight becomes half of his original weight
So everyone imagines that you eat a lot
but you are getting thinner and thinner
This is what we just talked about
The imbalance of his entire energy system
The imbalance of the energy system
It will also affect the entire system of our body
He will have problems
Well, this is animal research
Then we mentioned
In fact, in humans
you can't do this kind of research
Has it only been done in mice?
Are there other animals?
I want to know
Other animals are actually more advanced than mice.
...
...
...
...
...
It actually once had a
very special brain disease
Before I talk about this disease
I want to ask Bowen a question first
Suppose
Suppose you know
You have a familial genetic disease
Then this familial genetic disease
may develop when you are in your forties or fifties
In case of the disease
In the end, he will definitely die in about
dozens of weeks.
But he may not get sick. Really
...
...
...
...
...
...
...
...
Yes
But if it is detected
In the end
Either the disease
or not
As long as the disease occurs, it will definitely be out
Yes
In this case, you decide
You will definitely
You will definitely get tested
You need to know
You are so courageous
What do you mean
I really don’t understand
Why
Will have that ostrich mentality
No, in fact, in this story
In fact, there are many people
He chose not to be tested
Why
Because he will have a kind of pressure
That is, I may have a
similar terminal illness
I don’t know if it will happen
So they will think
I have been young
I want to live a very conscientious life
Okay then why do I ask this question
About a hundred years ago
There used to be a disease called
Fatal familial insomnia
It is a genetic disease
Then it is a mutation of the
protein in the brain
What about the mutation of this protein
Because it contains the gene
And then pass it on
The most typical one is
when he is about 40 to 60 years old
It is possible that the disease will occur
Once the disease occurs
it will become more and more difficult for him to sleep
In the later stage, he will not be able to sleep at all
Then when he is unable to sleep at all
he will also have a kind of night sweats
just sweat all the time
Then the weight keeps getting thinner
Then what happens in the end
is until he dies
So
we start from this
familial fatal insomnia
You can see that
there will be a very similar situation to the animal experiment we just talked about
...
that is, you don't sleep
In the end
you will have a caloric imbalance.
Okay, that's why
I will tell you
Why sleep
Because we
actually do a lot of work during the day
After you do so much work
you always have time
to let your entire system
and then let it do a reorganization
That health
Or the heat balance we just talked about
This is probably
the most basic
and is related to survival
The other
actually has some more detailed ones
For example, when our brain is in the daytime
you are constantly using your brain
When our brain uses energy
it will produce some metabolites
Those metabolites accumulate in your brain
After a long time
Your brain is getting dirtier
So when we sleep
you will be the most efficient
Get rid of these metabolites you produce during the day
Clear them
So imagine
it is very similar to
when you are very busy
your studio
your room
your office will be very messy
Then wait until this period of time is finally over
Then clean it well
Clean it a little bit
A little bit cleaner
Your work efficiency will be better
Then our brain
is actually similar to this mechanism
You just mess it up during the day
At night
Clean it well
After cleaning it
You will do it the next day
You can start the most efficiently
So the two
just mentioned are probably
We can use it to understand
one of the main reasons why we must sleep
In terms of survival mechanism
it is a necessary condition to help us survive
...
It is a behavior
Then our
For example, high efficiency
As far as our cognition
As far as our emotions are concerned,
it helps to make all our
behaviors during the day
Make a reset
I usually say
Just imagine before
You used the old Windows
After using it for a long time
Will you become slower and slower
The system will become more and more stuck
So what should I do at this time
Just reboot
Don't you need some kind of disk reorganization
I remember
This is similar
Disk reorganization is usually
What kind of cleanup
Anyway, it just clears some
Cookies
Right
Then this is a bit similar
We are talking about the memory system
When we sleep
the brain will keep the memories during the day
It judges that the memories are needed
Delete the unnecessary memories
Then combine them with the past memories
Then this is a bit similar
The disk reorganization you talked about
Although I answered you at the beginning
What will happen if you don’t sleep
You will die
It sounds serious
But it is
If we look at it from the perspective of evolution
you will find that
all living things sleep
all
even single cells
Sorry
I have to correct
plants
do you know
I used to
when I was writing a thesis
I once wrote this sentence
That's the same
You are like my advisor
My supervisor stared at me and said
All
Can you prove everything
Okay Most of them
I just wanted to ask
How primitive a creature is to begin with
It feels like it is more complicated to sleep
We have to mention this again
Can insects sleep
What is the concept of sleep
For example, let's take fruit flies.
Do you think fruit flies can sleep?
This question sounds like yes.
But the sleep of fruit flies
is actually different from what we
currently recognize as sleep.
Because we are talking about
and the core is talking about the function of sleep.
Since mammals,
before that, we would say that it has behavior close to sleep.
...
For example, how do we know that
this fruit fly is sleeping
Well, ideally
If the fruit fly stops in one place
Then you shake it a little
If it wakes up and shakes a little
it should fly away quickly
Under normal circumstances
the fruit fly will not stop in one place for a long time
So the researcher will judge that
In the 24-hour record of a day
It is during the day
If it is obviously more active
At night it is less active
If it vibrates slightly, it does not move much
Okay, then we will judge
The period when it does not move much
It is similar to a state of sleep
You just mentioned blue-green algae, for example
Yes
Will blue-green algae sleep?
This involves what we just talked about
In fact, the behavior of fruit flies
We can understand it as a kind of biological clock
It is an organism
Most organisms
must have this type
It has a fixed period of activity
and a period of inactivity
The native algae of blue-green algae
actually has a cycle of 24 hours a day
...
Actually, don’t talk about blue-green algae
It’s like 2019
Nobel Prize in Biomedicine
He explored it
At our molecular level
It actually has this kind of cycle of 24 hours a day

In our human cells
Most of the living things we can see
...
mostly have this
phenomenon of changing in a 24-hour cycle
And behind this phenomenon
is probably part activity
and part rest
What about the rest part
It is obvious that it is a big rest
We will understand it as
Behavior similar to human sleep
Then I want to ask
because I just talked about
the kind of big rest
But
two events in my life
made me come into contact with a
strange sleep mentality
One was when I was in college
Because at that time I felt that
sleep was very annoying
I am a person who needs sleep very much
I can't get enough sleep no matter how much I sleep
Then I feel
it's a bit of a waste of my time
Because I want to have more time
to do more things
So at that time
I had a senior who told me
There is something called the Superman Sleep Method
The Superman Sleep Method means
We usually don't lie down for 15 minutes like lunch break
Will we feel super energetic
It is to break
the sleep you need in a day
into 15 minutes 15 minutes 15 minutes
and then
become a kind of
without a very long sleep
But
I seem to remember it is
You only need to sleep for two hours throughout the day.
You only need to sleep for 15 minutes at a fixed time.
Then get up again.
Then sleep for another 15 minutes.
Because the truth is that
Some organisms are like this too.
...
...
...
...
Because this is the second time in my life that I encountered
a very similar experience
It was after I gave birth to a child
The cycle of a child is
Drinking milk and sleeping every three to four hours
Then you wait until he gets up next time
Drinking milk to sleep
So it is not just the child at that time
It follows this cycle
Parents will also follow this cycle
It is somewhat similar
Parents will not become this cycle
Parents will only be in pain
Yes
Parents will only be in pain
Okay, then what you are actually talking about is
Another concept of sleep
It is easy to be misunderstood
Sleep is usually ignored
Another feature
is the biological clock we just talked about
In our organism
Sleep
is determined by two main factors
The first is your sleep pressure
We usually talk about sleep debt
For example, if you don't sleep for 24 hours
your debt will be huge
You are very stressed
Then everyone will think
Okay, then I just need to get rid of the stress
The staged sleep you just talked about
focuses on the stress part
But in addition, the biological clock means
our biology
You have to do the behavior that matches that period at the right time
...
Only then will it be optimally efficient
In terms of humans
Because humans are diurnal animals
So diurnal animals
are active during the day
and rest at night
In other words, if we humans
carry out your behavior in this form
...
its efficiency will be the best
If we think from this perspective
from the perspective of evolution
You can understand
Sleeping at night
Its execution will be the most efficient
Suppose there is a person with a normal schedule today
For example,
your schedule is still the majority
Your biological clock should still sleep at night
But on a certain day
you are forced
to sleep eight hours during the day
Can the eight hours during the day
be offset by the eight hours at night
No
Because of the biological clock
Although you sleep for the same eight hours during the day
But your sleep structure
will be different from doing this at night
If you take a nap during the day
Can it help you refresh
Yes
But in the long run
it can allow you to maintain such a state
Then your brain and your body and mind
won't be affected
The current conclusion is no
If you are an ordinary person
The current conclusion is no
The kind you just talked about
In fact, there are some
in special situations
For example, some of them are doing it abroad.
He wants a single-handed sailboat
Then maybe cross the Atlantic
They may need one person
and then drive the boat
Then maybe drive
It may take hundreds of days
He must be awake all the time
Otherwise he won’t know when he hits the iceberg
In this kind of competition
They have done it
Have they ever used the method you just mentioned?
He just divides the day into twenty minutes
Within twenty minutes
He may take a nap
and then wake up
This can indeed help him survive the competition
But it is not suitable for a lifetime
Yes
Can he continue to do this after landing?
No
Because from those related research findings
His sleep pressure has been accumulating
so he still needs to catch up on sleep
Then I can ask
why it is said that
we are most efficient when we are awake during the day
and sleeping at night
Is it
just because of the sun itself
?
If we talk about the core
It should be a mechanism designed by our diurnal animals
It is like this
The sun
For us humans
For diurnal animals
it has a wake-up-promoting effect
That is to say
As long as you get up in the morning
and you are exposed to the sun
it can help you become more awake
And this subjective sense of being awake
will allow you to perform cognitive functions better
So for example, if you stayed up late the night before
and you feel groggy in the morning
But you have to work right away, what should you do?
...
...
...
...
The direct effect of sunlight on us humans
Because there are some people around me
They will turn day and night upside down
Usually more artistic
He is the kind of creator
or a performer
who performs at night
So he probably sleeps during the day
and then gets up to work at night
What impact will these people have on their bodies if they have been
like this for a long time
...
This actually has to be connected to
When we talk about the biological clock
In principle, in the current research
The conclusion of the biological clock is
If you can maintain a stable schedule
then it is basically OK
Because
Since the industrial revolution
electric lights have become popular
and now all the technology
has made our environment
not so absolute day and night
So in this case
current researchers mainly
You can think of it as the next best thing
At least you have to achieve stability
Stability is just like what you just said
If he is a person who goes to bed late and gets up late for a long time
Then he only needs to maintain this rhythm
For example, he may go to bed late and get up late for three days
Then it will become a normal state for three days
This will be chaotic
It is a bit like shift work
So as long as it is stable
Basically
the current consensus is that
it will not have much impact on the body
But to be honest, in the real situation
it is not easy for you to maintain such a schedule
...
Those who continue to work night shifts
are very similar to the situation you just mentioned
But they will still encounter a situation where
I have to take care of my family life.
My child is active during the day
Then should I take the child out
Then should I contact relatives and friends
So he still needs to interact with those people who usually
wake up during the day
and sleep at night
So there will still be a few days when he does not meet the
what he calls the situation of going to bed late and getting up late
I just thought of another example
Maybe it's like that kind of aviation personnel
Then they have to adjust the time difference all the time
Always adjust the time difference
So this is a
not good for the body
No need
It must be
It must be
My doctoral thesis is to study the biological clock
Then the conclusion after completing my doctoral thesis is
Try not to do shift work
But this is not the case
Because of our current society
You said it is impossible without shift work
So usually I will tell you
Don’t do shift work for too long
The research data is probably like this
If you are currently working in shifts
It means that your biological clock is chaotic
Then you suffer from various diseases
Various diseases here
There are all the diseases you can imagine
High blood pressure, diabetes, cardiovascular disease
Stroke, etc.
Then your risk of suffering from these diseases will increase
But
if you work for twenty years
Do twenty years of shifts
Then I will not work shifts
I will become normal
Then the risk will decrease again
In other words, at least
when humans are relatively young
we have a certain degree of tolerance to this
situation that goes against our nature
...
But please remember
it is against the design of our genes after all
So if you continue
the risk will continue to rise
Have you observed that at what age
is it almost time to start to stop
Like Boen when you were young
You can also stay up for a long time
Stay up late without sleeping
That's right
It won't be a problem
I can't do it anymore
That's right
I could do it before
But not now
So
Probably according to my tolerance
I think it will be after the age of thirty-five
It will be obvious
The number of unbearable situations will increase significantly
So I will probably say
Okay
Then if you really want to take shifts
you should cut it off for a while
At least if you really want to do it in the future
try to find a fixed shift
better
Yes Foreign studies have actually found that
those who work regular night shifts have better health than those who work three shifts.
Their physical health
is better.
Yes
Why do I know so clearly? Pretty stable rule
...
...
...
...
Right But it's different from ordinary people
I only slept once for forty-eight hours at that time
So it was
because I couldn't finish writing
There were too many things
There were too many things to read
And then there were too many things to write
So I slept once every two days
Then I had an accident
at that time and I wanted to confirm this
That's what I suddenly discovered
After I had been sleep deprived for a long time
I don't know why
My mood became happier
It's strange
Because it's counter-intuitive
I know it all
All I learned before is
Sleep deprivation will definitely make your mood worse and worse
But I had one at that time
It seemed like a kind of joy after death
Then I went to check
I Google at that time
sleep deprivation induced euphoria
Then I really found the result
Yes
Then I was scared to death
But like
in recent years
that kind of fitness
or a more popular one among their ethnic groups
...
long-term fasting
Even in the past, everyone also thought that
eating every day
no one can continue for more than five days and seven days
Not eating
But later some studies said
Oh, if you have a long fast
it will be helpful to restore body functions
...
So the question I want to ask is
Is there actually such a thing
That is, you are sleep deprived for a long time
Then your body will know
I can use sleep more efficiently
Is there such a phenomenon
Well, I think this idea is very good
Right
Okay
Let me first add to what you just said
which is
Will lack of sleep make you happier
There is a
treatment for specific severe depression
It is sleep deprivation
There is a group of severe depression
He took medicine but it didn't work.
Nothing worked.
Then tell him not to sleep.
He would have a similar effect. There is a situation where he will be like this
...
...
...
...
...
...
...
...
One possible reason is that your brain will
become more and more arousal
That is, it will become more and more awake
And this more and more awake
will give you more control
Then you can do more and more things
Especially those things that will give you positive feelings
For example, you were writing a script at that time
Then you don't sleep for a long time
and then write more and more vigorously
to enter the flow state
and then feel a sense of accomplishment after finishing writing
wow
you feel so good
This is actually also true for some artists
They are unique
why do you end up in this kind of situation at night
just have to stay up late all the time
Then when I was doing research
I once thought about a hypothesis that
when you stay up late to a certain extent
is it possible that your brain will become more creative
This is actually one of the
one of the views
because
we are studying creativity
The core is that you have to leave
your original framework
you have to break it
But when your brain does not sleep for a long time
It is
Physiologically already failing
Right
So you have to leave the frame
This is called disintegration
Then you will be in a kind of
wow
Unconstrained
Even if you stay longer
it is actually possible to have some delusions or hallucinations
Delusions or hallucinations sound more serious
but you can understand it as
You will be more likely to have
some thoughts or feelings that you would not otherwise have
...
But I want to emphasize again
This is not something that everyone will have
There are some people who will have this situation
So you can understand it as
like what you just said
OK Then I don’t sleep at night
I can not be disturbed
I will enter the flow
And I will be particularly excited when writing scripts
So it will become one of the possibilities for many people to say
I have to stay up late to complete
...
Everyone should have an experience
If we talk about final exam week
Then we stayed up late and read a lot of books
Then the moment I finished all the subjects
I fell asleep very deeply
It’s not that I forgot
Hahahaha
I just forgot
Good teacher
This is something only teachers have
students We don’t care about forgetting or remembering
After all, the exam is over
Yes, yes
It’s just that the sleep after
is very comfortable
Yes
This is sleep pressure
Yes
Because you haven’t slept for a long time
Our body will accumulate sleep pressure
Sleep pressure is in our brain
We have an indicator called
adenosine
Our Chinese name is probably adenosine
That is to say
If you continue not to sleep
your accumulation of adenosine will be more and more
When your adenosine accumulation
becomes more and more, it will form your sleep pressure
And the higher your sleep pressure
you will enter sleep
The so-called deep sleep
The longer it will be
And it will be deeper
Usually when we evaluate deep sleep
, there will be two indicators
One indicator is
how long your deep sleep lasts
It is the quantity
The other indicator
is that we can measure his brain waves
If his brain wave is slow wave
N amplitude
It means the greater the amplitude
That also means that his quality
The quality of deep sleep will be better
So when your sleep pressure is greater
Usually quality follows quantity
He will show
More preference for deep sleep
So people who don’t sleep well are not tired enough?
This
can also be regarded as
One of his possibilities
Yes, but as we just said
In fact,
there are many factors that affect sleep
Yes, I just
This is actually the point that I care about the most
I think
I seem to
have always had a
no matter how long I sleep
there will be a feeling that it is not fully charged
Just like that mobile phone
and then plugged in all night
it is not fully charged
Then
I have a little story recently
that I had an operation recently
So I needed general anesthesia
And during the general anesthesia
I slept so well
Never before
I haven’t slept so well for a long time
And anyway, when I was undergoing surgery
I seemed to be still snoring
while operating
Because my wife was recording me
and
snoring so loudly
Because it was indeed recorded
So
I could hear the doctor
talking to my wife over there
The doctor said
This is how he usually does
Then my wife said yes, it was so noisy
This should be
that one You can buy a
suppressive respirator
I feel that his normal sleep
should not be of good quality
Then
In fact, I have been talking about
I can't sleep well
Others gave me suggestions
It seems that I can test it
to see if there is respiratory arrest
This is actually
One problem that most of us
have
is if you snore
and very loudly
while sleeping, and occasionally it will happen
as if he stops snoring mid-snoring
We usually recommend
some diagnosis
But I want to add something more about the anesthesia you just talked about
...
In fact, there are some studies
They actually use deep anesthesia
to simulate our deep sleep
Because the appropriate
is related to the dose of the anesthetic
and its ingredients
That is, the dose and ingredients of the specific anesthetic
can cause our brain waves
A state similar to slow wave
So there are some animal experiments
He used this anesthesia instead to say
If the organism enters the sleep state
What would it look like
There was once a study
You should probably listen to it
He would say that sleeping on the side is better for our sleep
I only heard that sleeping on the side will not snore
There is nothing wrong with sleeping on the side as less snoring
Well, sleeping on the side is better for sleep
His theory behind it is to use animal experiments
to put the animals into anesthesia
Then he measured the state of brain cleaning
which is the state of clearing away those metabolites
Then he found that under the anesthesia state of sleeping on the side
its removal efficiency will be better
So there are some sayings
Okay, then we should all sleep on our sides
But that’s not the case
Okay
Let’s get back to it
Some people will mistake anesthesia for sleep
For example, some people will go to some medical aesthetic clinics
and ask them to help them with that
kind of sleep
You can do this
Of course not.
But you also know that this world is
some are not good but some people can
It is actually illegal
but some people do do it
There are actually
in foreign countries. Well, this situation will appear
First, he will have an addiction
Because those narcotics
are our neurological drugs
Secondly, those will make you cause that kind of
The state of deep unconsciousness
In fact, what you just described is another
We have a very interesting feeling about sleep
Think about it
In fact, humans really don’t know
what it feels like after sleeping
It is an evaluation after waking up
So we always feel that
if I lose consciousness
I completely lose consciousness
That means I slept well
That's right
Right, so you just said it
You are in anesthesia
Although your brain waves also have slow waves
But you feel
I completely lost consciousness for a while
It feels so good
It feels like sleeping
But it is not
I just want to explain to everyone
Never use this technique
I thought you seemed to be really sleeping
Actually, it's really not
But I raise my hand again and ask
It's the family I mentioned at the beginning
...
Then fatal
Yes, fatal insomnia
Can't they use drugs
to make them sleep
The current situation is
Because he is in the brain
The system that controls his sleep and wakefulness
has been completely destroyed
So even if he takes drugs
his brain still cannot function normally
Of course it can
The situation you just mentioned
is a bit relieved
But his damage
will definitely become more and more serious
So he will end up with the same ending
In fact, it is the same
Just like we do animal experiments
Animal experiments, for example, mice don't sleep
Is there any way we can delay it?
Yes
We let it eat high-calorie food
High-calorie food mice can live longer
Because we just said that it will have a caloric imbalance
and will keep losing weight
So you only need to give it high-calorie food
He will live longer
This is also very interesting
because it is very similar to everyone's experience of staying up late
That is, you will be very hungry
in the middle of the night and will want to eat
In fact, to a certain extent
you can also regard sleep
or lack of sleep
as a kind of stress
We evolved
when you are under pressure
You will do several actions
The first one is of course to accumulate energy
So you should be resting at night
But you are not resting
You will be alert to a certain extent
Is there an enemy coming?
So I have to reserve energy
So when I can eat
Of course I try to eat as much as possible
Research also found that you are eating late night snacks
You will especially like to choose high-calorie foods
Compared with normal times
Right
If we judge this from the evolution we just talked about
...
This is a state of stress
So you have to choose high-calorie foods
This sounds very reasonable
So I will try not to go to bed too late
Because you don’t let your brain
Falling into that wrong cognition
That's right
It's really hard for you to challenge your brain like this
...
Understand
Because we just talked about adenosine
Then deep sleep and these things
The question I want to ask is
What are the reasons why we
cannot enter deep sleep
Like respiratory arrest
It is a
What is the cause
Just
Why do some people do this
We can understand
Our sleep still goes from light to deep
That from light to deep
In addition to your brain
Your muscles will become more and more relaxed
The core reason why breathing is suspended
Your respiratory tract will be blocked
When you lie on your back
You may have this side of your neck
Or which side of your respiratory tract is narrower
Because your muscle tension is relaxed
so it will collapse
So you can imagine our respiratory tract
It is originally a relatively elastic tube
Then wait until you go to bed at night
It may become less elastic
Then there will be some weight on it
Then press it down
Because your muscles are relaxed
Then press it down
Then it gets clogged
Our brain
For example, when you first start sleeping
It's okay
It's not blocked yet
Slowly getting more and more blocked
Once it gets blocked
Your blood oxygen concentration will drop
If the blood oxygen concentration drops, you will die
So your brain will wake you up
So it will form
You originally went from shallow to deep
But when you are deep, you will be blocked
So before you reach deep
, the brain will wake you up
Then wake you up and you will go back to shallow
Then shallow and then deep
Then wake up again
So those with severe
sleep apnea
will have almost no deep sleep
Then there will be almost no deep sleep
The impact will be very, very large
Therefore, clinical studies have also found that
if that kind of case of sleep apnea
he is at risk of suffering from various chronic diseases
I want to repeat it again
Stroke, cardiovascular disease, diabetes, hypertension
As long as you can imagine those chronic diseases
, it will be significantly increased in cases of sleep apnea
...
So we usually
If the person I am giving a speech to
is a man over 40 years old and obese
As long as we combine these three
we will say
You evaluate whether he snores at night
Is it very loud
Wait a minute, obesity is related to
because of all the heat regulation just mentioned
So he will gradually start to gain weight
Because there is a kind of stuffing
because for example, his neck
may have a lot of fat
You can also imagine it when you are lying down
He will press it down completely
and then it will be stuffed
When facing men
We will talk about this more
Wait a minute
I just heard a key point
What about women
Women don’t snore
Her risk of sleep apnea
She is indeed significantly lower
Is it gender discrimination or something?
There used to be some claims that
it is related to estrogen
But I haven’t updated this since
so I’m not sure
When I was studying
I saw a saying
Estrogen is in the body
Indeed, on many levels
there is some protection for women
We have also seen that
after menopause
many of her risks
will actually increase
This was a statement I understood at the time
But where is the current research
I don’t know much
Because about gender hormones
I only studied it when I was studying
Understand
Then I just heard a keyword is
adenosine
What is my impression of this word
It is related to coffee
Yes, yes, yes
Sure enough, I study Neuroscience
I really want to ask today
That is
Certain substances that can affect sleep
Like coffee
Then
In fact
I wasn't that into magnesium before
I just didn't see that much magnesium
Then in recent years
a lot of people have told us to eat magnesium
What is it
Why
I also feel that everyone
needs to eat a lot of things now
In addition to magnesium,
what other fish oils are there?
Many things
Well, the first one is
Adenosine
It is produced naturally by our body
When you are awake
The brain
You can think of it as a metabolite
So when our brain is awake
It is because it is constantly working
So it does have various metabolites
What is special about adenosine is that
the more it accumulates
it will make your brain not want to work
and make your brain go on strike
and you will want to sleep
And caffeine
The structural formula of caffeine itself
is very similar to adenosine
So if you drink coffee
For example, you may not have slept for 24 hours.
So you have a lot of adenosine.
That means a lot of adenosine.
Adenosine must be combined with receptors
It will produce a drowsy effect
What about caffeine if you eat it
It will occupy the hair pit and stop pooping
It will combine with adenosine receptors
But it will not have any effect
This is why if you drink caffeine
it can keep you awake for a period of time
This is the most important element
But what about
Your caffeine occupies the hair pit and you can't poop
But adenosine is still being produced
and accumulating
So if you continue not to sleep
your caffeine must be replenished all the time
Because the half-life of caffeine
In terms of normal humans
is about 4 to 6 hours
What is its tolerance
It means that our receptors will keep increasing, right?
Adenosine receptors
Adenosine will continue to accumulate
That receptor is fixed
But
the time that caffeine occupies it is fixed
It cannot occupy it forever
Because it will disappear after a period of time
It has a half-life
It will be metabolized
Then why do people talk about drinking coffee
and the more you drink it, the less effective it becomes
This is related to tolerance
But this part may involve
the knowledge of caffeine
I used to
I was going to a place where we were talking about coffee
Let’s talk about what we just talked about
Then someone who knows coffee very well told me
If it is really good coffee
it will not affect sleep
Then I was very unable to understand
What is really good coffee
What we just understood is
The structure of caffeine itself is very similar to adenosine
Right
So as long as it has this structure of caffeine
it will definitely have an impact
So the difference is
The degree of caffeine in this coffee
Right
The difference between more and less
There are indeed different coffee beans
and different roasting methods
which will affect its composition
So my understanding is
some coffee can have less caffeine if you
brew it properly
...
This is my understanding
That's bad coffee
I drink coffee to wake up
not for the taste
Yes, it depends on whether you need coffee
Do you need caffeine
or the taste of coffee
Then if I drink coffee during the day in order to sleep deeper
...
so that I can crash before going to bed
my body will collapse
All the adenosine rushes in
Is it easier for me to enter deep sleep
In fact, I think this method is not that
Not that effective
In theory
In theory
I thought it was OK
In fact, instead of this
you can do something simpler
For example, you can do more activities during the day
The other one is to expose yourself to more light during the day
In fact, modern people often ignore the effect of sunlight
on our sleep
The effect of sunlight
The first one is that it can make our biological clock
more stable
As we just said
our organism is stable
This pattern of waking up during the day and sleeping at night
So you only need to make this pattern more obvious
The more obvious means
For example, there are some office workers
who are in the building during the day
Then he may order delivery at noon
Then when he gets off work, it may be
dark or dusk
So for him
you can imagine that the time he really gets sunlight is very short
...
For example, our studio is very dark now
We only have this kind of photography light
So if you shoot here all day
...
you will have very, very little light today
On the other hand, if someone is out for a day
For example, at least he will be outside for more than two hours
Maybe more than two hours
Then these two types of people
The light he receives during the day
Sunlight is different
Different will affect
his secretion of melatonin at night
You can also understand melatonin
It is one of our neurohormones that helps you start sleep more easily
...
Apply what we just said
As long as you have moderate light exposure during the day
That helps your melatonin to be secreted more easily at night
...
It is easier to secrete
and it is easier for you to enter
What we just talked about
It’s good to fall asleep
Or enter a deeper sleep
That’s why I say that instead of using coffee
that way
you might as well go to the light
It’s actually a simpler method
I’m also quite curious about melatonin
That’s
because it’s not sold in Taiwan
Is it sold in Taiwan
Taiwan has a prescription
You have to go to a doctor
OK
But it is OK if you bring it back from abroad
It seems to be
I remember it is
Yes
Because
Basically every time I go to the United States
I will buy melatonin
Yes
Is it effective for you?
It is effective for me
It is very effective
But my wife took it but it didn’t work
So when should you take it
before going to bed?
Do you take it before going to bed
In fact, generally speaking
if we are
and you are really using melatonin
it is probably an hour before going to bed
Its use time will be a little earlier than
Generally taking sleeping pills
Yes Because melatonin
we will think of it as
it lets your body know that it is night now
So it is an indirect effect
It does not directly promote your sleep
We can imagine that
organisms
diurnal animals sleep like this
You must first know that it is night now
Then first know that it is night now
Relax slowly and slowly
Then enter the sleep state
So melatonin lets you know
It's night now
It's the prelude to sleep
That sleeping pill
It acts directly on your brain
The mechanisms related to falling asleep
So it is taken before going to bed
So this is something we don't know much about
If you have insomnia
Unless you are that kind
It has to do with biological clocks, jet lag, etc.
These influential people
otherwise would not directly recommend taking melatonin
Then there is another reason why it is not effective
For example, many people
It may be due to stress
The pressure here
No, my wife should not have any stress
But there is another one
Then please ask
Is my wife someone who thinks too much
Probably not
Probably not
Then what is the most likely cause of your observation
I think she moves too little
Then will she use 3C at night
Calculate
Computer TV Mobile phone
Yes TV
Then we can connect this again
We just talked about the biological clock and lighting
Just now we talked about daytime light
It can make your biological clock more stable
Then there is another one is daytime light
If you light it for a long time
and then the intensity is relatively high
It also has another effect
It can offset the effect of using 3C at night on melatonin suppression
...
Yes. You also know that you use 3C at night
This light will inhibit your melatonin
This is an inherent inhibitory effect
And this inhibitory effect
is a comparative concept in the human body
...
That is to say, if you shine very strongly
and have a relatively large amount of light during the day
then the impact of this mobile phone on you at night
will be smaller
because you can imagine
When you are outdoors, it is more than 10,000 lux
Then the light on your mobile phone or indoors
is about 300 to 500
So in this case
your entire body's biological clock
will be in a relatively stable state
Your melatonin suppression will be less
But suppose there are some people
who don't go out much during the day
So he doesn't get much light
and he doesn't move much
Then his biological clock
We would say that he is in a comparative state
Not obvious
Our normal situation is
The more active you are during the day, the better
The less active you are at night, the better
But if your activities
during the day and at night are similar
then his biological clock is not obvious
His secretion of melatonin
will be relatively gentle
So this is why we recommend
just those elders
Because some elders
may also have difficulty moving
But even if you have difficulty moving
you
still need to go out to get some light during the day
or do some activities
Because this way your biological clock
will be in a stable state
Your sleep at night
The secretion of melatonin will be stable
How long should the light be used?
Or
What to do on a cloudy day
Or if it’s sunny
Can I only do it for five minutes?
For suggestions for stabilizing the biological clock
Probably at least 30 minutes
A long time
30 minutes of light
You don’t need to be exposed to the sun
For example, you can hold an umbrella
You can be under the shade of a tree
You can be under the arcade
The light received
Flashes
Because light will flash
The light you receive
probably has thousands or at least tens of thousands of lux
The light of our general office
If our office has fluorescent lamps
That's only about 300-500 lux
So you can compare
the difference in intensity
It's actually very big
But for us humans
In fact, for the light intensity of 500 and 5000 lux
you are not so obvious
You are oh, it is brighter
But you won't think it is ten times brighter
Therefore, many modern people suffer from insomnia
One of the factors is
Anyway, I have light all day long
But the light is indoor artificial light source
The frequency band of artificial light source is different from that of sunlight source
...
So its effect on stabilizing our biological clock
will be different
This was actually more obvious during the epidemic in 2020
...
You can't go out because of the epidemic
You will be locked at home all day
Then at that time, the epidemic was stressful
Then there was this problem of the biological clock
So there were very, very many people who couldn't sleep well
...
Exercise is good for sleep, right
Very good
So far
If I go out to give lectures
If someone asks the teacher, I can't sleep well
How can you help me sleep better
Then you also know
In fact, there are hundreds of reasons for not sleeping well
So far,
there are probably two types that can be recommended
One is exercise
An integrated analysis of exercise in various items
And each
its approximate effect is positive
But
It has a premise
It is best to exercise during the day
Apply what we just said
Humans are self-motivated animals
So you can exercise during the day
It can just make your biological clock
more stable and stronger
What if
but it is not possible
I have to go to work during the day
What should I do if I can only exercise at night?
Usually our advice is
It is better to exercise than not to exercise
So the first
If you really can only exercise at night
you still have to exercise
The second
is the best time for you to exercise
Three hours before your sleep time
This comes from
Because we exercise
you will have sympathetic nerves working
Then your sympathetic nerve function
changes to a more arousal state
You need time to let it come down
So the closer this period is to the time you fall asleep
the greater the impact it will have on your sleep
Of course, this will be related to your age
Boen, most of your audience should be young
Not necessarily
It is a normal distribution with me as the middle
Yes, yes,
Yes, the younger ones
They will be affected by this
In fact, it will be smaller
Because everyone is actually young
When I was in college
We only came to practice team practice at ten o'clock in the evening
We finished practice
I can still sleep when I go back
Then many people say
You are not tired enough if you can't sleep
You hurry up and exercise
Yes, so exercise makes you more tired
Then you will sleep better
Such a point of view
If it is to be completely established
It must be during the day
If it is at night
It will have other factors
For example, age
The intensity of your exercise
The time of exercise, etc.
There will be other factors added
Understand
I think it is a bit connected
The Superman sleep method
What I care about most is individual differences
Because I will be very jealous
People who don’t need sleep very much
Then
Right
No
My time in this world is short enough
Why spend a third of my time
in simulated death
That's
Have you ever imagined
If one day
I really have some technological methods
so that you don't have to sleep
Do you think you are happy
Very happy
I want to quote
the famous book
Inside Fullmetal Alchemist
OK
Equivalent exchange
Alphonse Elric
What he said
Have you seen that one
Yes
Because he turned into armor
There is no need to sleep
He said
When everyone is sleeping and I wake up alone
I am very sad
I am very lonely
That is when he does not have to sleep at night
In fact, he is very lonely
That is really his problem
There are many things that can be done
Good He doesn't have a short video to slide
So what you said is fine
Okay
Then can you not sleep
In fact, there are many opinions about this matter
...
I recently
When I went to a place to give a speech
there was an audience
The audience
looked like he was in his seventies
He told me
that he only needs fifteen minutes of sleep a day
Then I said
Really
You have been like this since you were a child
Yes He said he had slept very little since he was a child
and other people who knew him
also agreed on the spot
saying that he really slept very little
This is because there is no way to do experiments
so I don’t know
Okay This is the first example.
What about the second one?
Is it possible?
...
...
...
...
...
...
...
...
...
But those people with short sleep genes
Their average value is about five
That is to say, their range
is from four to six
Related to sleep
There is a DEC2
This gene
He found that their family
If it is inherited on this gene
If there is a mutation
They really don't need to sleep a lot
What about the other one?
When this gene was first discovered,
some media called it the
elite gene.
Oh,
yes,
because it has this gene mutation. It means that you talk on the phone
...
...
...
...
...
...
and do other things at the same time
He may do it faster if he switches on the attention
...
This is what the media said at the time
As for this short sleep gene
His subsequent research so far
There are about four to five different genes
that can have similar effects
But
is it shorter
So far
Scientific practice has not found a shorter time.
It is really done through research.
In humans, it is about four to six.
Those people with short sleep genes
They have all slept very little since childhood.
...
...
...
...
...
As we humans age
our sleep efficiency will become worse
The short sleep gene
It can show a characteristic
That is
this type of person
His sleep efficiency
is even better than that of ordinary people
So now scientists want to know
his entire mechanism
How does it work
Is it possible to replicate
Now it can be replicated in animal experiments
Then if it is possible
Can it be replicated in humans
Yes So this is the current short sleep gene
that most wants to be operated
I just wanted to ask a question
because I didn't just say that
there was an old man in his seventies
who only sleeps fifteen minutes a day
But our
general impression of the elderly
is that they are not sleeping
not
because the old man
Still go to bed early and get up early
Anyway, they are old people
Is there a tendency for people to sleep less as they live older
...
From a normal perspective
So far, it is believed that
aging has little influence on his sleep hours
Just how long he has to sleep
...
The current international consensus is that
Even if you are over sixty-five years old
You must sleep at least
about seven hours a day
Why does that impression form
The first
Because when we age
our sleep at night will advance
That is, the biological clock will move forward a little
The second
I want to modify a statement
It is for older people
Then his ability to maintain long sleep
will be poor
because of the bladder
Yes
It should be said that many people will have heard of it
That is
For example
He may go to bed at ten o'clock
Then he may wake up in the middle of the night
Maybe at three o'clock
He no longer looks like he was when he was young
Can sleep for eight hours at a time
OK Well, this is actually because our ability to sleep for a long time becomes worse after we get older.
But it's not because he doesn't need it.
...
So some studies will find that
Look at some elders.
Although they may sleep very little at night,
but sit there and watch TV during the day.
It's easy to fall asleep.
Then sit there and watch TV during the day.
It's easy to fall asleep.
What does it mean?
It means sleepiness.
His sleep pressure is high.
We think that elders don’t need to sleep.
But they are in a state of high sleepiness.
...
...
...
...
...
When I was young
I could sleep for ten hours at a time
But now I sleep about seven hours
or even less before I wake up
I was just thinking
if it might be
because as we get older
sleep naturally decreases
leading to their energy imbalance
Then humans will slowly
move towards
But it doesn't sound like that
OK
Let's go back and ask again
It's the person who studied the short sleep gene
Then their body
may have a certain mechanism
Or it can synthesize a certain protein
so that it can remove waste more efficiently
Then if we find out
what that thing is
How will it be applied in practice
Could it be taking a certain supplement
In fact, the most likely possibility of genetic programming is
adjustment through gene editing
...
This is my current imagination
Because you also know
There are some gene editing technologies now
So if
it is a hundred years later
We have really located which genes
It's like this
Then we can really
do it through gene editing
Then such an operation
may be possible
But people who have been born are already hopeless
Right? It can only be the fertilized egg
Then we have to see how far the gene editing technology can go
...
My understanding of genes is
As you grow
you can still modify the genes to a certain extent
...
This is the current view of epigenetics
So how far can this modification go
Or how far can our gene editing
go?
I don't know this
But according to the current human race
I want it very much
But I still have to explain
In fact, the current research on short sleep genes
is actually quite new
Because
I remember the first research at that time
It seems to be 2019
That really
also progressed very quickly
But in fact, our human technology
is usually like this
You will see its positive effects in front of you
But the negative effects
usually appear after a period of time
So after it has been modified like this
What will be the impact on us humans individually
Or the overall impact
What will it look like
I don’t know
Then I want to talk about dreams at the end
Because I feel that dreams are
and they can also happen in sleep
But there is another whole big branch
Dreams
We just had a chat before we started recording
Do dreams have meaning
This sentence is very provoking
Do dreams have meaning
This matter
From my point of view as a rather biased
brain scientist
Ah, just discharge
The way it can make sense depends on
your interpretation of it
It’s not about the dream itself
Because our brains will naturally remember our internal
past memories
present memories
It will have some weighting
That is, if there are some things that are more important to you
it will make the connection of its
memories deeper
And dreaming at night
The act of dreaming
If viewed from the perspective of brain science
It is a phenomenon
and this phenomenon lies in the activation of specific areas of your brain
...
Especially the sensory association area
Because the side of our brain is the temporoparietal junction
Then you have an area that connects feelings
and actions
and your past memories
Then when you sleep at night
Your brain area in this area
It is stimulated under specific circumstances
In other words,
it will stimulate a lot
with feelings, actions, feelings
Brain areas related to memory
Then the so-called dream feeling
and this dream feeling
If you interpret it through people
you may have some insights
It is comprehension.
It turns out that it is like this
Because
The so-called psychotherapy
Or the so-called meaning
One of its core elements is
Do you accept it
Wait a minute
But what I wanted to ask just now is
What is its physiological meaning
Dreams help eliminate this doubt
Let me help consolidate
Let me give you an example
The nightmare I have had very often recently
This is true
I have this nightmare very often
I will dream that I am on the battlefield
Already at war
Then a bullet will just
hit my chest
Everyone should have the kind of
where things are about to end
Just hypothermia all over the body
Then it's over, over, over
I want to die here
It's over, over
I don't want to die
I don't want to die
Snap and wake up
Because this is a nightmare
Repeat this dream several times
PTSD
Why should it be consolidated
or
It doesn't seem to be helping to rule out
this
There is a saying that
dreams do, to a certain extent,
help us practice
practicing what may happen to you
a bad experience
or a bad event
so that
more dangerous situation appears in the dream
Another way of saying is
When your negative experience
is the emotional experience
or the accumulated
experience is too powerful
it will get stuck there
and continue to stay there
There was a study a few years ago
He said that this type of people will have recurring dreams
In his brain at night
About the secretion of adrenaline
He will still show a
relatively non-stop state
because the adrenaline in our brain
should be static at night
Especially during REM sleep
it should be almost absent
But for this type of person
he will still secrete it to a certain extent at night
...
In other words, your brain should relax
Your brain should forget
You need war
Need to escape that thing
But it still exists
I think this is very interesting
Because growing up
I will feel that I rarely dream
But whenever I dream, it must be a nightmare
I almost never had good dreams
And then it was all this kind of tension
For example, during that student period
I always have a dream that
I can’t finish the exam
Then I have to hand in the paper
Then I do poorly in the exam
This is my extraordinary nightmare
Almost after I graduated
5, 6, 7, 8 years
I am still having this nightmare
That trauma
Yes This traumatic experience is very strong
This is also the traumatic experience after growing up that is unique to many academics
...
In fact, we need to clarify it again
In fact, you are talking about the dream you remember
Because the dream and the dream you remember
are actually two different things
We are at night
You will have about 4 to 5 times of REM sleep
The study will find that you probably
as long as you wake up in REM sleep
you will have about 70% to 80% of your dreams
In other words, one night
On average there should be 3 to 4 dreams
So the difference is whether you remember or not
Then why do you remember
One of the reasons is
You wake up after you dream
That's why you remember
Then why do you wake up
One part is
That is your last dream
Just because you will get closer and closer to the early morning
What about the last dream
It is in our entire sleep structure.
Another feature
is that
the closer you are to the dream state in the second half of sleep
the stronger its emotionality
and the weirder the plot will be
the weirder it will be
so
most likely if you have a dream
in the later period
and its emotional tension will be high.
It’s easier to remember when you wake up
In response to your question
The simpler answer is
It’s not that you didn’t have a good dream
It’s just that the good dreams are not strong enough for you to remember
Why can’t I have a very strong good dream
Yes This is what makes human beings very hard
It is related to the mechanism of our entire organism
Because living organisms are inherently concerned with negative events
He will pay more attention
Because negativity is related to survival
Your erotic dreams have nothing to do with your survival
Dreaming about erotic things just makes you happy
But bad dreams
Those survival-related dreams
are related to your survival
So I think many things
are designed towards such a mechanism
So when you are sleeping
the stronger the negative emotion
it will actually affect your physiology to a certain extent
For example, if you are hit in a dream
then your heartbeat
will actually become faster
Have you seen the full-scale startup
What is mentioned in the full-scale startup
If the person in your dream is hit
Or you really died in your dream
Then you will also die in real life
This is actually to a certain extent
Your physiology will be connected with your dream
Yes, so in this case
If you have a strong negative experience emotion
it will easily make you arousal
Then arousal will make you wake up easily
When you wake up, you will remember
About that kind of all human beings
Almost everyone has a common dream
It is how psychology explains it
For example, falling from a very high place
Have you ever had this dream?
It should be said that this type of dream
Swimming in the sea
Then wakes up and wets the bed
This kind of
Wetting the bed in the sea
It's best if it's just me
Have you ever had these dreams
You didn’t come from a very high place
Keep falling and falling
Very few
I have very few
It should be said that if we interpret it based on human experience
He seems to be mostly related to his pressure
and the entire imbalance he has recently created
The imbalance in life
As for what you just said about swimming in the sea
Then the matter of bedwetting
This is actually what we talked about earlier
Your physical feelings in the dream
will be connected to your dream
Yes
Because when your bladder becomes more and more full
Your body will give you a message
Water-related messages
Information related to wanting to pee
So this message is to a certain extent
Will enter your dream
Then he peed in the dream
He also peed on the real bed
Yes So this comparison is
the physiological signal of your real body
and then enters the dream
And there are actually some studies on this
It is the external environment
He can also enter the dream
For example, there was a study
He would let people sleep there
and then detect their entry into REM sleep
Then sprinkle water on his face
Just use that kind of shower
Just use the foggy kind of water
Then he discovered
If he does this
About 42% of people
You wake him up
Just sweep the water and wake him up for a while
Ask him what dream you just had
He will say that there is the element of water in his dream
Just like for example
I originally dreamed that I was recording with Bowen
Then suddenly I don’t know why
The studio sprayed water
That’s
Originally there was no water in the dream
But after you do this operation
the water element will run in
This is similar to starting the movie
So
this is actually some
research on dreams.
Knowing internal and external messages
will affect the content of dreams
Then some people will use this method to operate
Didn’t you just say that
I really want to have a good dream
There are also some sayings that
There is specific music
Give him chocolate
Chocolate
It may not be easy during sleep
Because there are more operations during sleep
Can use smell and sound
There are some theories that it is specific music
played during REM sleep
It enters your dream through this music
It is easier for you to have a good dream
But there is no consensus on this so far
There is no consensus in research
It is more of a commercial statement
And this statement sounds like it makes sense to you
...
Because the music enters the dream
The sound will enter the dream
But
does it have such a great influence on our so-called good dreams
...
This may be another issue
I will ask a question first
and then ask a related one
A question that may be more controversial
is that I have a friend
Then he seemed to run to read
It should be Freud's stuff about dreams
I seem to have read that
this dream
is relatively shallow
In other words,
requires the use of more complex reasoning
or the concept of conditional clauses
will not appear in dreams
You will not have a dream
Then for example
What if tomorrow
What will happen to me
There is no such situation
I said Oh, right
Then I went back and observed for a while
Then I found that
Oh no
My dreams still have this hypothetical tone
But what I am curious about is
What we know now
The brain areas involved in dreams
Is it really lower cognition?
There was once a study like this
It put people to sleep
and then used brain waves of a specific frequency
using the method of transcranial magnetic stimulation
and then hit it in the same way
probably at the junction of the parietal lobe and the temporal lobe
As we just talked about
the sensory-motor joint area
and then through frequency stimulation
It can give you the feeling of a dream
And no matter which sleep stage you are in
You can also do it in REM sleep
You are in non-REM sleep
I just need to hit it
You will have the feeling of a dream
You can also imagine
If you just hit this place
It is indeed related to those memories
Feeling
Kinesthetic related
In addition, the logical reasoning you just talked about
is mostly in the prefrontal lobe
Well, some studies have indeed found that
in dreams
The main one that is active
is what we just talked about
Compare the junction of the parietal lobe and the temporal lobe
There are some people whose prefrontal lobe
It will also be slightly active
If you are more active in the prefrontal lobe
In fact, your ability to
the logical reasoning we just talked about
and even self-awareness
will be stronger in comparison
Then I will mention this
There is a rather special kind of dream
Lucid dream
Lucid Dream
You once knew in a dream
Are you dreaming
Yes, yes,
There have been
Yes, yes
Yes, there is some research on that
He just wants to know
What is the difference between knowing that you are dreaming in a dream
and not knowing that you are dreaming in a dream
Then his conclusion is
those who have lucid dreams in their dreams
His prefrontal lobe will be significantly more active
Of course, the temporoparietal junction is also the place
If we use a simpler version to explain
The reason why you have lucid dreams
is that your brain's prefrontal lobe
and certain dreaming brain areas
are more active than the average person
On the contrary, it is
The area of your brain that should be relaxed is not relaxed
So you are more likely to be in a dream
You can know that you are dreaming
Even you can control your dreams
Yes, because advanced ones can control dreams
You can even dream within a dream
The issue of dreams within dreams
Let's go back and talk
For example, from the perspective of Jung or Freud
Do dreams have meaning?
Then I would like to know
Do your so-called dreams have meaning?
What kind of dream does it include?
A dream in which you don’t know you are dreaming.
A dream that you know you are dreaming
Then a dream that you know you are dreaming has something to do with it
You know you are dreaming
But can you control it
Yes
If you can control
Are dreams you can control meaningful
Is that still called a dream
Yes
It feels like you are already awake
Which dream within a dream is meaningful?
And what we just talked about
Our external messages
can affect the content of your dreams
Right
Well, if you are affected
Is this dream meaningful
How should you interpret it
Yes So this is from the perspective of neuroscience
We can see many different aspects of dreams
The manifestation of dreams has very diverse forms
Maybe
Maybe some
Through our interpretation after waking up
It does show some aspects of the subconscious
But does it also show some aspects of the subconscious
From my current point of view
If we put all the current operating methods
into it
it is actually one
It is difficult to say how meaningful it is
Okay
Let's talk about another
researcher on the science of dreaming
They actually have to define
what is a dream
What do they define
For example, everyone thinks
if you
have a picture drifting past
then the picture floats past for only two or three seconds
A still picture
Is this a dream
No
Right
Then if a thought floats over
Is this a dream
Probably not
Then if in the dream you feel that you have experienced something
but there is no strong emotion
For example, if you are writing in a dream
You have no picture
You will feel that you are writing.
Is this a dream
It should be
What kind of feeling is called a dream
So in the end there is a group of dreaming scientists
Their definition is like this
In dreams
You must have a certain degree of emotion
Then its plot must be a little weird
Or in an obviously realistic situation
That is, you can't just have some thoughts floating over.
The picture floats past
This does not count
Right
Okay, let me talk about this
In fact, I also want to let everyone know
During sleep
Those phenomena that you have similar to
Consciousness expression
It is not just dreaming and non-dreaming
It is not so single
It is more like a spectrum
There are some very complex ones
It may have strong emotions
Weird plot
But go this way
It might be an ordinary plot
No emotion
Go a little further this way
It might just be a picture
Go a little further this way
It might just have one idea
So
Where do you want your so-called dream to be?
Then it is meaningful
My current point of view is this
If it is that kind of
your naturally occurring dream
Then you wake up and still remember
Even what you just said
has a recurring meaning
I think this is indeed important to us people
...
Dreams are very much like the beginning of the brain.
You may be randomly stimulated.
In that random stimulation,
there may be some clues connected to
your past or your current situation.
Some important experiences in the recent period.
or important emotional experiences.
...
...
...
I will interpret it as
such an emotional experience or memory
For me as a person
For my brain
It is to judge its importance
I try to interpret
What is the relationship between the memory behind my recent life
and my past life context
Then if I can evaluate it correctly
I might know and say
Oh, so
something is going on
My conscious mind may have been trying to ignore it
Then if
can really give me such a reminder
Then I will say
Oh okay
Then my subconscious tells me
I should do this
So I am willing
to listen to my insight
Please note that this insight
is still the insight you interpret
I am willing to listen to the insight I interpret
Make some changes
Okay I just think
Because I just emphasized that
it is still a layer of meaning after your own interpretation
...
So for me,
this stimulation
is the same as anything you hear a song
or you see
If you hear a song
the lyrics will be written into your heart
and then say
I never knew I valued this matter so much
Its meaning seems to be the same as the meaning of dreams
To me
It won't be the same
Because dreams are created by you
Well
Because you do hear the song
and you will have some insights
Just because this song
may affect a certain memory of yours
or affect a certain feeling of yours
That's why you appear
The touch you just mentioned
or insight
The difference between dreams and songs is
it is more like the message that appears in your brain
...
It is not a message you can control
but it is generated by you
So we humans naturally
will generate this inner message
for me
I will be more willing to believe
understand
but I recently had a little story about my son
I also think
if you are very pure at heart
and you are also very
honest about
what you like or dislike
The interpretation of this dream seems to be
not so necessary
Anyway, my son has recently
He started dreaming
I was surprised
He was three years old
Then he would dream
He would remember the dream
He would also describe his dream to me
Then he woke up one time recently
He said
Dad, I just had a dream
I dreamed
You take me to 7-11
Then you buy candies for me
Then I want to say
ok
It is indeed a dream
He is very clear
He likes to eat candies
His desire
Yes
He wants me to take him to 7-11
The contents of dreams are all memories
And memory will involve several points
That is, is it possible that he was induced
or is it possible that he
went to
desires
what I want
So of course I think
to modify his dream
because of some of my current
the child is very innocent
He will not have this
He is less likely to have this situation
He may be more
faithfully relaying the content of his dreams
But if it is an adult
In fact, when you are awake
the information you are exposed to
or
the induction given to you by others
He will
affect your dreams to a certain extent
In fact, here
what I want to express is
Dream research
Actually, to be honest
it is really difficult
Because it has something to do with your memory
It has something to do with your ability to express
People with good expression ability
He can talk a lot
So all this is
We are talking about so-called dreams
Does it have any meaning
And how to study dreams
and so on
I think it is still very
a difficult place
Just leave it alone
Don’t explore
Yes
Because it is difficult
But do you know
In fact, after I started studying psychology
One of my own views is
Dreams are the last piece of the puzzle that unlocks human mental ability
Don't you think that most of the psychological sciences
...
now study the waking state
The waking state of consciousness
Right
Later, after the science of sleep began to develop
we also know that during sleep
Your brain also has some operations
And when you sleep
These operations will come back
to affect your mental function during the day
But when sleeping
there is another very special situation
That is dreams
Whether dreams are considered consciousness
Of course we can have a lot of discussions
But at least your so-called dream display
is a part of our mind
A very special expression method
And this expression method
Why is it like this?
Why has it not been evolved
If from an evolutionary perspective
we say it must have its function
Then what is its function?
It is still very unknown so far
Although there are some functional theories
but it is still difficult
to cover the entire theory
Why do we still have these phenomena
So I always feel that
if our human research
continues until we can unlock the secrets of
dreams
By then we should have almost understood the entire human mind
...
Because the secret of dreams is too difficult
Like the Final Frontier of Space
This dream is of human consciousness
Final Frontier like this
There is another question
I am not asking
Which exercise is very important for sleep
Then you say go outside
Basically, you will give two suggestions
For sleep
Then one is exercise
What is the other one?
You actually remember this thing
That's right
I want to applaud you again
I feel like
Haha
The other one is actually a practice similar to
Mindfulness
...
It is mindfulness
or meditation, meditation or yoga
...
This type of exercise
Yes
Because it mainly comes from many people nowadays
I thought it would be something like
a balanced diet
No
It is Mindfulness
In fact, a balanced diet is mostly
I assume that there is not much difference in nutrition
...
Under this premise
we will probably give something like this
Mindfulness suggestions
This actually mainly comes from modern people
In fact, they are not very relaxed at night
Because you are still lighting up at night
Still looking at 3C products
So ideally our normal night
should be like that farming era
The light is very weak at night
Then you will hardly use your brain
But we modern people
our brains
are constantly operating
when we are almost awake After a long time, it will form a kind of inertia
That is, your brain will feel that
as long as you are awake, you have to keep working
keep working and working
Then there will be a kind of
similar to forgetting
or not knowing what state
is a relaxed state
After a long time, it will not be conducive to falling asleep.
When falling asleep, we will say
You must relax your brain before going to bed.
...
...
...
...
...
...
...
Or similar related studies have found that
you can make it easier for your brain to shut down through this kind of practice
...
Then I want to add this part
In fact,
in our brain
Regarding sleep
In fact, many people will think that
there is a switch in our brain
And this switch
Turn it on and you will wake up
Turn it off and you will sleep
But it is not
Our mechanism has two switches
One switch is for wakefulness
and the other switch is for sleep
So
the ideal situation is
For example, this side is awake and this side is sleeping
The level of wakefulness is higher during the day
Awake is on
The sleeping one must be turned off
Then wait until you slowly and slowly get longer and longer
You have to be awake more and more
Turn off more and more
Then sleep is more and more open
So wait until before going to bed at night
Sleep is completely turned on
Wake is completely turned off
So you can sleep well
Right
Then the situation we just described is
You turn it on when you are awake during the day
Right
Then as you stay awake longer and longer
your sleep pressure increases
So your sleep system is turned on
but your waking part is not reduced
Or it is not reduced enough
In this case
it will become difficult for you to fall asleep
Then this is also the most common case of insomnia among modern people
...
This is one of the problems
Then combined with another one is
When you can’t sleep well
What behavior will you do to help you fall asleep
Then this will be off track
Off track means
If you are doing the right behavior
It will help you reply
But if you do the wrong thing
it will make you sleep worse and worse
I can imagine that everyone is swiping their phones
Hahahaha
Yes, but when it comes to swiping their phones
In fact
it’s hard for you to say it in one word
Swiping your phone or 3C is definitely not good
You know a while ago
I read a study
That is
For certain ethnic groups
Watching some TV 30 minutes before going to bed
It helps them sleep
What kind of person
is a person whose brain continues to operate during the day
A person who operates at a high speed
Then you can imagine
For that kind of person
He is watching TV
Watching those brainless dramas
Then he will feel that
this to me is relaxation
So it is actually still a relative thing
You have a stimulus that can help him
Don't think so much
Then just watch mindless dramas over there
So for him
he can still relax
But what about
if you look at the entire mechanism
It is not the best way to relax
It's just that for some people
it is still relaxing
Then if you can learn a deeper sleep
Like what we just talked about
Meditation, meditation, yoga
Mindfulness, etc.
These are deeper sleep
If you can master this method through practice
...
Then your wakefulness switch
before going to bed will be easier to turn off
Then it will be easier to turn off
You can adjust those biological clocks
sleep pressure
...
Your sleep will be easier to unfold
So the problem of insomnia among modern people
Do you want to say it is stress
It is indeed stress
But what about
After stress
Is your treatment method
headed in the right direction
This is the most critical point for most people
doing cognitive behavioral therapy for insomnia
...
So
we often hear that
Just watch TV
Just exercise
Anything is fine
Because everyone
is among the factors of sleep
Where he went wrong is different
So it's hard for you to have a
simple solution
I can imagine that some things
are helpful for sleep
For example,
the curtains really need to be completely dark
or all the lights should be turned off
Because light is obviously related to sleep
I know
But I saw that you wrote an article
that means
temperature will also affect
yes
high temperature
yes
After I saw it, I thought
wow, what did
emphasize over there
Now the air conditioner needs to be turned on 26 27
Nonsense
I can’t sleep well
This will start fighting again
Who cares about the earth
I want to sleep
In fact, it has something to do with our temperature regulation
Our body temperature goes down
The body temperature here refers to the core body temperature
The core body temperature goes down
It will also make you more prone to drowsiness
So in other words
Of course you are at a higher body temperature than yours
You also need a low-temperature environment
That will help your body temperature drop
The definition is very broad
In this way, it is easy to sleep as long as it is below 37 degrees
But it can affect our core body temperature
It is usually lower
The research is like this
Sometimes we will see some
Citing research from Western countries
They will say about 18 degrees
But in fact
wow
you can know 18 degrees
For us Taiwanese,
is super cold
Right
So later
kept peeing
Some later research
My own interpretation is this
This will depend on you
Our original living environment
In the school where we taught before
there was a Japanese professor
and his office was super cold
Every time I entered his office
I said you won’t be cold
Then he wore short sleeves
This is just right
Yes Therefore, the
original environment
where they live in different countries will affect the
optimal sleep temperature we just talked about
There are some studies in those Western countries,
It is about 18 degrees
But I also saw some later
In Asian countries
such as China
and their research in Malaysia
is actually about 23 degrees
Not bad
Yes But is the best 23 degrees
You also know
In fact, all behavioral science research
is to find a group of people
and then do it
Most of the people they find are adults
They are young people
So is your 23 degrees
applicable to everyone
Actually it is difficult to say
So most of the suggestions we give are
that environment
The first is your temperature
You should feel cool
Comfortable
And the humidity should not be high
Because the humidity is high
It will be more difficult for you to dissipate heat
So in this situation
It is easier for you to fall asleep
Then if it is too cold
For example, if I am 18 degrees
I will definitely feel super cold
In that case
it will be harder to sleep
Understand
Thank you very much today
Teacher Yuzhe shared so much
Very interesting
Dreaming
Physiological
How to fall asleep
There are also some of the most practical
is mindfulness
Exercise
and
The air conditioner can be turned down a little bit
My personal favorite
Today I would like to thank Teacher Yuzhe very much again
Thank you
Then today’s episode of blog is recorded here
vs there is no point in the middle
See you in the next episode
Goodbye
