What is sleep?

Sleep is when your body and brain take a rest. During sleep, your heart beats more slowly, your breathing becomes steady, and your muscles relax.

Sleep is not just about resting, though; it helps your body repair itself and your brain organise memories and information from the day. 

Without enough sleep, people often feel tired, grumpy, or have trouble concentrating.

Why sleep is important

Sleep helps your body grow and stay healthy. While you sleep, your body releases hormones, such as growth hormone, which help you grow and repair your body. 

Your brain also uses sleep to sort out what you learned during the day. This is why students often remember things better after a good night’s sleep. Sleep also gives your brain a chance to rest, which helps you feel alert and happy during the day.

How much sleep do we need?

Children and teenagers usually need more sleep than adults. Many professionals say that school-aged children need around 9 to 11 hours each night. Teenagers need about 8 to 10 hours. Adults often function well on 7 to 9 hours of sleep, but everyone is different. The right amount of sleep can help improve mood, attention, and even energy for playing.

Tips for better sleep

Good sleep habits can help you get enough rest. Try to go to bed at the same time every night and avoid screens before sleeping. A quiet, dark room is easier for the brain to relax. 

Doing calming activities, like reading a book or listening to soft music, can also help. Healthy eating and exercise during the day also make sleep more refreshing.
