Sleep is a very important part of staying healthy. When you are asleep, your brain uses that time to take care of itself. Some scientists think your brain sorts things out when you sleep and that it also replaces chemicals it needs. The rest of your body needs sleep, too. While you are sleeping, your body stays busy by using that time to heal itself. It also uses that time to build up your immune system, which is the system your body uses to fight off germs. Your body also uses your sleep time to build up muscles, bones, and tissues so that you can grow. Sleep helps you think clearly and stay in a better mood. That helps you to cope better with a busy day
