Draft:Outline of sleep

The following outline is provided as an overview of and topical guide to sleep:

Sleep – naturally recurring state of muscle relaxation and reduced perception of one's surroundings, with a decreased ability to react to stimuli, similar to being in a coma, but more easily reversed by being woken up. Adequate sleep is essential for maintaining health. During sleep, most of the body's systems enter an anabolic state, helping to restore the immune, nervous, skeletal, and muscular systems. Sleep occurs in repeating periods, during which the body alternates between non-REM and REM ("rapid eye movement") sleep. Dreams occur during sleep&mdash;fantasies in narrative form resembling waking life while in progress, but usually distinguishable from reality upon waking. People may suffer from various sleep disorders, classified as dyssomnias, parasomnias, and circadian rhythm sleep disorders.
