You spend about one-third of your life sleeping, but what really happens when you close your eyes? Sleep is more than just rest; it’s a complex biological process that your brain needs to function properly.
Why Do We Sleep?
- Energy Restoration: Your brain and body recharge during sleep.
- Memory Consolidation: Sleep helps organize memories and learning.
- Toxin Removal: While you sleep, your brain clears harmful waste products.
Stages of Sleep
- Light Sleep (NREM): Your muscles relax, heart rate slows.
- Deep Sleep: Physical repair happens here.
- REM Sleep: Dreams occur, and your brain processes emotions.
What Happens If You Don’t Sleep?
Lack of sleep affects memory, mood, and even immune function. Chronic sleep deprivation can lead to serious health issues.
