The brain is the control center for the body. It receives and makes sense of signals sent from nerve cells in the body and sends information to the body’s muscles and organs. It also controls a person’s thoughts and feelings. Sometimes it is called the busiest communication center in the world. Your brain can’t work hard non-stop. You need have a healthy sleep to make your brain and your muscles work properly.

During sleep, some parts of your brain are less active than others. But the brain never stops working completely. Parts of the brain are active when you are dreaming. And part of the brain looks after certain body functions. These functions must go on all the time. Among such functions are the beating of the heart and breathing.
Sleep gives the nerve cells in your nervous system a chance to restore their energy.
