sleep cycles

Sleep cycles are natural patterns your body follows during sleep, typically lasting about 90 minutes each. Each cycle includes stages of light sleep, deep sleep, and REM (rapid eye movement) sleep. Light sleep helps you transition in and out of sleep; deep sleep is when the body repairs and restores itself; REM sleep is when vivid dreaming occurs and your brain processes memories. Throughout the night, you go through multiple cycles, with REM periods becoming longer later. Proper sleep cycles are essential for physical and mental health, ensuring restorative rest and overall well-being.
