Understanding REM Sleep
🧠 What is REM Sleep?
REM (Rapid Eye Movement) sleep is the stage where most vivid dreams occur. Your brain is highly active while your body is temporarily paralyzed.
📈 REM Percentage
REM sleep typically makes up 20-25% of total sleep time in adults. The first REM period is short, but they get longer as the night progresses.
💡 Brain Benefits
REM sleep is crucial for memory consolidation, learning, creativity, and emotional processing. It helps strengthen neural connections.
🎯 REM Cycle Pattern
You cycle through REM sleep 4-6 times per night. Each REM period lasts 10-60 minutes, with later cycles being longer and more intense.
⚡ Peak Hours
Most REM sleep occurs in the last third of the night. This is why cutting sleep short can significantly reduce REM sleep.
🔬 Health Impact
Adequate REM sleep supports mood regulation, immune function, and cognitive performance. REM deprivation can impair these functions.
