Updated 29 January 2004, 17.50


PSHE 11-14/KS3/Levels E&F
Health influences

Overview
German scientists think that your brain doesn't take a break while you're asleep, and instead keeps on thinking.

In this activity, students advise a friend on how to avoid sleepless nights.

Learning aims

  • The function and importance of sleep

  • Give advice to someone having trouble sleeping
Icebreaker
Read the stories:

Discuss the following questions:

1. Why is it important to get enough sleep?

  • It repairs body and mind.

  • Your dreams help your brain to sort out all the information that it has been dealing with.

  • Deep sleep helps body tissues to regenerate.

  • Sleepless nights are often a contributory factor to poor school performance.
2. What happens if you don't sleep?

A 17-year-old schoolboy, Randy Gardner, stayed awake for 11 days in 1964. He holds the record for sleep deprivation. He began to suffer from:

  • Blurred vision and incoherent speech
  • He saw objects as people
  • He suffered a mild degree of paranoia

How well did he recover?

He recovered quickly when he finally slept. On the first night afterwards he slept for 8 hours and on the next night 15 hours.

Teachers' Background

Advice for when you can't sleep:

  • Try to go to bed and get up at the same time every day.

  • Don't stay in bed because you've had a bad night's sleep. Get up so that you don't disturb your internal clock.

  • If you wake at night, relax in bed for a while. If that doesn't work, get up and try some quiet activity until you are sleepy again.

  • Chocolate, coffee, tea and soft drinks that have caffeine in them may keep you awake. Your body needs four to five hours to halve the amount of caffeine in your blood.

  • Give yourself some time to write down worries or concerns about what you will do the next day.

  • Don't eat too much just before bedtime.

  • Regular exercise during the day will help you sleep.
