Sleep States

Sleep states refer to different stages of sleep your body cycles through, each with distinct brain activity and functions. The main stages are Rapid Eye Movement (REM) sleep, when most dreaming occurs and the brain is active, and Non-REM sleep, which includes light sleep (stage 1), deep restorative sleep (stage 3), vital for physical health and memory. These cycles repeat throughout the night, helping your body repair tissues, consolidate memories, and restore energy. Understanding these stages highlights sleep’s importance in maintaining overall health and well-being.
