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
