Sleep Physiology

Sleep is a condition of reduced muscle movement in the body. Awareness about the surroundings is reduced at the time of sleep. The body stays mildly responsive or non-responsive to external stimuli. The sleep-wake cycle is controlled by the circadian rhythm that produces a resting phase for the body.
