In physiology, sleep is a "readily reversible suspension of sensorimotor interaction with the environment, usually associated with recumbency and immobility."[1]
Sleep stages
The stages of sleep include "Stage 1: sleep onset, drowsy sleep; Stage 2: light sleep; Stages 3 and 4: delta sleep, light sleep, deep sleep, telencephalic sleep"[2] and REM sleep. REM sleep is "characterized by rapid movements of the eye and low voltage fast pattern EEG. It is usually associated with dreaming."[3]
Disorders of sleep
Obstructive sleep apnea
Sleep abnormalities and associations with other diseases
Abnormalities of REM sleep such as excessive motor activity are associated with subsequent Parkinson's Disease and Lewy body dementia.[4]
Reduced amount of sleep may be associated with cardiovascular disease such as coronary heart disease and stroke.[5]
