NREM Sleep

NREM (Non-Rapid Eye Movement) sleep is a phase of sleep characterized by slow brain activity, reduced heart rate, and decreased muscle tension. It makes up about 75% of total sleep time and involves three stages: light sleep, a transitional phase, and deep sleep. During NREM sleep, the body repairs tissues, strengthens the immune system, and consolidates memories. It is restful and restorative, providing the foundation for good health. This stage is distinct from REM sleep, where vivid dreams occur, and the brain is more active. Overall, NREM sleep plays a crucial role in physical and mental restoration.
