to catch up on your sleep.
Here are three reasons why you should get more sleep:
Your boy needs sleep
As a teenager, you must get enough sleep – more sleep than an adult. Your body is still growing and your brain is still developing. Experts say that you should get between eight and nine hours of sleep each night.
Sleep helps you do better at school
When you’re tired you can’t concentrate in your lessons. It’s more difficult to learn.
Sleep keeps you healthy
Without enough sleep, your body gets weak, and it’s easy for you to catch a cold and other illnesses. When you are tired you often eat food with more sugar in it and that isn’t good for you.
How to get a good night’s sleep:
You shouldn’t watch TV, surf the Internet or play computer games before you go to bed. To get to sleep, you need to feel relaxed.
If you’re hungry, have a light snack. You mustn’t eat a big meal before you go to bed – it will keep you awake.
You shouldn’t drink any drinks with caffeine or sugar in the evening.

Task 2. Read the article again. Answer the questions.
1) Why do teenagers need more sleep than adults?
2) How many hours of sleep do teenagers need every night?
3) What happens at school if you don’t get enough sleep?
4) Why do teens eat unhealthy food when they are tired?
5) What two things should you avoid to get a good night’s sleep?
