| Abstrakt: | The human body cycles through two phases of sleep, (1) rapid eye movement (REM) and (2) non-rapid eye movement (NREM) sleep, which is further divided into three stages, N1-N3. Each phase and stage of sleep includes variations in muscle tone, brain wave patterns, and eye movements. The body cycles through all of these stages approximately 4 to 6 times each night, averaging 90 minutes for each cycle. This article will discuss the progression of the sleep stages and the unique features associated with each. (Copyright © 2022, StatPearls Publishing LLC.) |
