It's important to get enough sleep.
We are often told that it's important to get enough sleep,
but do we know why?
The truth is,even scientists can't agree on why we need to sleep.
However, it's clear that the less we sleep,
the worse we perform in everyday life.
Have you ever felt tired in the middle of the day,especially after lunch?
Actually,this is quite normal.
Researchers have found that it may be healthier to sleep twice a day a long sleep at night,
and a nap in the afternoon.
Even a ten-minute nap at lunchtime can allow us to work better in the afternoon.
And if we really can't find a chance to nap,
we should get a longer sleep at night
so we don't feel tired after lunch.
Not getting enough sleep has serious effects
on our brain's ability to work.
If you go without sleep,
you might have problems with your memory or with your concentration.
In order to concentrate at school or perform well in tests,
we really need to get a good night's sleep.
Some people have trouble sleeping,
especially if they are nervous or stressed about something.
Sleep experts say that it's better
not to try too hard to get to sleep
and certainly not to keep looking at the time.
To have good sleeping habits,
it's better to sleep at regular times,
and to sleep in a dark and quiet environment.
It's also good not to sleep too soon after eating,or after drinking too much water.
The amount of sleep we need is different from person to person,though the average sees
to be just under eight hours.
Jim Steed, a sleep researcher,
has a simpler way of looking at it.
"Forget about facts and figures.
If we feel tired in the daytime,
it means we need to get more sleep."
Section 3 After You Read
3a Check (√) the information that we can infer from the reading.
