This is News Review

I'm Beth.
And I'm Phil.

Now, today's story.
Our brains get smaller as we get older,
but this doesn't happen as fast
in people who take
regular short sleeps during the day.
That's according to
a new study. Researchers suggest
that these naps might reduce the risk
of developing conditions
like Alzheimer's in later life.
You've been looking at the headlines.
What's the vocabulary?
We have 'power nap',
'sharp', and 'hinder'.
This is News Review
from BBC Learning English.
Let's have a look
at our first headline.
This is from iNews.
Power naps linked
to greater brain capacity, scientists say.
So brain capacity is about
brain size and
this headline says that it's linked
to something called 'power naps'.
Now we're going to look
at this phrase 'power naps',
but Phil, the word 'nap'.
Isn't that
a short sleep that babies have?
Well, anyone can have a nap,
but we're looking at 'power naps'. Now,
these are short sleeps,
usually during the working day in order
to be able to do your job better.
And in fact, maybe I should have
a power nap after recording this.
Well, that might be good for your brain.
That's what this headline is saying,
but there are other types
of nap, aren't there?
Yes, you might have heard of
a 'cat nap' which is kind of similar,
but it's not associated with work and
we have other words to talk about sleep
like 'snooze' or
'to nod off' and many others.
OK, well before
our audience nods off.
Let's look at that again.
Let's have our next headline.
Yeah. This one is from the Times.
Taking more naps could help you
to stay sharp
in later life.
Now, again, we're talking about naps
and this article refers
to another study which suggested
that having naps can help
our brains perform better.
The word. We're looking at is 'sharp' .
Now, Phil.
I know a sharp knife.
But what is a sharp
brain?
Well,
you've probably guessed that.
It's a metaphor.
If you describe someone as 'sharp'.
It means they're alert
and they can think quickly.
Think about when you've had
a good rest, and you're feeling good.
Everything just seems to be
a bit easier.
Yep, and we use it to talk about people
that always have a quick answer
for something. We can say that they are
sharp or that they have a sharp mind.
Yes, and it's being used here to say that
regular naps will keep your brain
performing well.
Yes, just like
how practising your English
every day will keep
your language skills sharp.
OK, let's look at that again.
OK, next headline please.
This one is
from the Daily Express. Naps
could help or hinder your health,
depending on their length, study suggests.
Now, this is actually referring
to a different study and it says
that long naps can be associated
with obesity while
shorter naps can reduce the risk
of high blood pressure.
We are looking at the word 'hinder'.
And this is often used with the word
'help' isn't it. It is,
but it means the opposite. To 'hinder' means
'to make things harder'
or worse. Now,
here we are looking at health.
So, the headline is saying that
some naps - shorter ones - are helpful.
While others - longer ones -
are unhelpful.
That's right and 'hinder'
is not that common in spoken English,
but it is often used
with the word 'help'.
And that's because of
those two 'h's. Hinder and help.
So, for example,
if something turns out to be less
useful than you expected it to be.
It might actually hinder rather than help you.
I could also say
that having to work hinders me
being able to take naps regularly.
That's right.
OK, let's look at that again.
We've had 'power nap'.
A short sleep during the day.
'Sharp' - alert and quick thinking.
'Hinder' - to make something
difficult or worse.
Now, there's more about sleep in this video,
where we ask 'are late nights bad for your health?'
