Rapid Eye Movement (REM) sleep

Rapid Eye Movement (REM) sleep is a unique phase of sleep characterized by quick movements of the eyes, increased brain activity, and vivid dreaming. Occurring several times during the night, REM sleep is essential for cognitive functions such as memory consolidation, emotional regulation, and learning. During this stage, the body is mostly paralyzed to prevent acting out dreams. REM sleep typically makes up about 20-25% of total sleep time and plays a vital role in overall health and well-being, contributing to mental and physical recovery.
