Why Sleep Quality Matters More Than Hours
8 hours in bed but still exhausted
You're getting enough hours but waking unrested. Sleep quality - how deeply you sleep - matters more than duration.
Common Causes
- •Fragmented sleep
- •Insufficient deep sleep
- •Sleep apnea
- •Poor sleep environment
- •Screen use before bed
What Our AI Detected
Quality is measured by time in deep and REM sleep. You need 1-2 hours of deep sleep and 2 hours of REM nightly. Without these, you feel tired regardless of total hours.
✓ Deep sleep does physical restoration
✓ REM sleep processes emotions and memory
✓ Wake-ups interrupt cycle completion
