It remains a common misconception that sleep means that the body is at complete rest. The fact, however, is that many functions, like the release of hormones, organs, general metabolism, and more, are still on in a sleeping body.

Physical and mental rest
Rejuvenation of energy
Optimum function of bodily organs
