Sleep cycles consist of several stages, including light sleep, deep sleep, and REM (rapid eye movement) sleep. Each cycle lasts about 90 minutes and repeats multiple times during the night. REM sleep is when most dreaming occurs and plays a key role in memory and emotional health.

Proper sleep cycles are essential for physical and mental well-being. Disruptions to these cycles can lead to fatigue, poor concentration, and health problems. Maintaining good sleep habits helps ensure restful sleep and supports overall health. Shutdown123
