Why Do We Sleep?

Sleep helps your body and brain develop and grow. Your brain needs sleep so you can:

  • Remember what you learn

  • Pay attention and concentrate

  • Solve problems and think of new ideas

Your body needs sleep so your:

  • Muscles, bones and skin can grow and fix injuries

  • Body can stay healthy and fight sickness

You spend the day running on the playground, learning at school and eating meals — and at night your body and brain get to rest, right? Wrong! In fact, while you are off in dreamland, your body and brain are very busy getting ready for a new day. That is why it is so important to give yourself time to sleep.

Kids ages 5 to 12 need 10 to 11 hours of sleep each night. When you get enough sleep you can:

  • Pay better attention in school

  • Be creative and think of new ideas

  • Be in a good mood

  • Get along with friends and family

  • Solve problems better

Without enough sleep you can:

  • Forget what you learned

  • Have trouble making good choices

  • Be grumpy and in a bad mood

  • Have trouble playing games and sports

  • Be less patient with brothers, sisters and friends

  • Have trouble listening to parents and teachers

To get better sleep, make sure your bedroom is cool, quiet and dark. Ask your parents to help with that. Try to go to bed at the same time every night. Your body gets used to a schedule and will be ready to sleep. Exercise during the day. And have a relaxing bedtime routine, such as a warm bath or shower, reading or listening to quiet music. Your body will know it’s time to get ready to sleep.
