why you need sleep?

Answer 1

You need sleep so your body can repair and fight germs. Sleep also regenerates you so you can feel refreshed when you wake up. Sleep also gives your body a chance to rest you muscles and lets your heart beat at a slower rate.

Answer 2

Why should you sleep? Everyone needs sleep. Without sleep, people are less efficient and more irritable. All adults require from seven to nine hours of sleep to function at optimum level. Sleep gives your body a chance to rest and make any necessary repairs, not just from illness and injury, but from the stress and strain of everyday life.

During sleep, the brain begins its housecleaning, taking immediate memories and turning them into short-term memories and taking those things stored in short-term memory and moving them into the warehouse of long-term memory.

About 50 years ago, the study of sleep entered a more sophisticated age, and doctors were able to break down the various stages of sleep - including REM (rapid eye movement) sleep necessary for dreaming - but answers to more basic questions have proved elusive.

Hints about why sleep is necessary can be found in the behavior of those who do not sleep enough.
