Sleep cycles refer to the repeating periods of sleep during a typical sleep period, primarily composed of REM (Rapid Eye Movement) and NREM (Non-Rapid Eye Movement) stages. These cycles facilitate various physiological and cognitive processes essential for health, memory consolidation, and overall well-being. A complete sleep cycle lasts approximately 90 to 120 minutes and repeats multiple times through the night, shifting in structure and duration as sleep progresses.
