AI Sleep Insight
Your sleep quality is improving. Over the past 7 days, your average sleep score increased from 72 to 85. Deep sleep percentage improved significantly on April 1 and 2, suggesting your recent lifestyle changes are having a positive effect.
Recommendation: Maintain your current sleep schedule. Consider tracking dietary patterns — high-quality sleep on Apr 1 correlated with lower caffeine intake.
Science-Based Tips to Improve Your Sleep Quality
Consistent Sleep Schedule
Go to bed and wake up at the same time every day — even on weekends. Irregular schedules disrupt circadian rhythm and reduce deep sleep by up to 20%.
Reduce Screen Time Before Bed
Blue light from screens suppresses melatonin production. Avoid screens 1 hour before bed or use blue light blocking glasses.
Optimize Sleep Temperature
The ideal bedroom temperature for sleep is 65–68°F (18–20°C). A cooler room helps your core body temperature drop, triggering deeper sleep.
Exercise for Better Sleep
Regular aerobic exercise increases deep sleep duration. However, avoid intense workouts within 3 hours of bedtime as they raise cortisol.
How Is the Sleep Quality Score Calculated?
The sleep score is a composite metric (0–100) calculated from four components:
- Duration score (30%) — How close you are to 8 hours of sleep
- Deep sleep score (30%) — % of night spent in deep (NREM stage 3) sleep
- REM score (25%) — % of night in REM (dream) sleep
- Continuity score (15%) — Number of awakenings / interruptions
A score above 80 indicates excellent sleep. 60–79 is average, below 60 suggests significant sleep debt or disruption.
