overall review score: 4.7
⭐⭐⭐⭐⭐
score is between 0 and 5
NREM (Non-Rapid Eye Movement) and REM (Rapid Eye Movement) sleep are two distinct phases of the sleep cycle that together comprise a typical night's sleep. NREM sleep includes stages of light to deep sleep characterized by slow brain waves and reduced physiological activity, facilitating physical restoration. REM sleep, on the other hand, involves rapid eye movements, heightened brain activity, vivid dreaming, and plays a crucial role in memory consolidation and emotional regulation.
