The best food for the brain is sleep, so you’ll need a lot of sleep during exam times. When you’re tired you will find it difficult to concentrate and learn.

So, how much sleep do you need? Well, when you’ve had the right amount of sleep you don’t feel tired, not too much and not too little. Most teenagers need between 8 and 9 hours sleep a night.

Try and get good quality sleep. So, don’t sleep with your books all over your bed or with lights, music or the computer on. For the best sleep, make sure your room is quiet, comfortable and dark.

If you stay up late studying and don’t get enough sleep, you may need a ‘power nap’ in the afternoon. A short sleep of 30 minutes may give you some energy before you start revising, but keep it short – you don’t want to spend all afternoon in bed!

Tips to help you sleep

  • Have a regular bed time. Try to go to bed at the same time every night, if possible 8 or 9 hours before you have to wake up.
  • Do plenty of exercise. Don’t do exercise just before bedtime, but regular exercise earlier in the day can help your body sleep at night.
  • Don’t drink caffeine (colas, tea or coffee) in the afternoons and evenings. Drink water, fruit juices or herbal teas.
  • Have a milky drink just before bedtime.
  • Relax before you go to bed. When you have finished studying, read a book, listen to music, watch TV or have a bath to help you relax.
  • Turn off lights, your computer, mobile and any other electrical devices in your room.
  • When you wake up, open the curtains to get lots of natural light in your room. This will help you feel more awake in the morning.

How many hours of sleep do you usually have on a school night? Is it enough or do you think you need more sleep?

I usually sleep 8 hours at night and I don't take a nap. As usual, I think this is enough. But when the final exam is coming near, I'll sleep about 5 or 6 hours and become a night owl.

I usually get 8-9 hours, and it's enough, I never feel tired. When I don't get enough sleep, I can't function well whole day long, so I go to bed earlier.

These Tips are definitely right.
It's so strange! while I have an exam I feel very very very sleepy.
But in holidays I can stay awake till 2 or 3 am!
Unfortunately almost every time when I have exams I won't have time to sleep more than 5 hours.
