Apple Watch Sleep Tracking
How accurate is Apple Watch sleep tracking?
Apple Watch sleep tracking is 85-90% accurate for detecting sleep/wake patterns and total sleep duration. For sleep stages (REM, deep, light), accuracy is around 60-70%. It's most reliable when worn consistently and combined with third-party apps like Reverie for deeper analysis.
How to set up sleep tracking on Apple Watch?
Open Health app → Browse → Sleep → Get Started → Set sleep goal → Configure sleep schedule → Enable 'Track Sleep with Apple Watch'. Ensure your watch has watchOS 7+ and at least 30% battery before bed. Wear it snugly but comfortably on the same wrist nightly.
What are the best sleep tracking apps for Apple Watch?
Top sleep tracking apps include Reverie (advanced analysis and personalized insights), Sleep Cycle (smart alarm), AutoSleep (detailed sleep stages), Pillow (comprehensive tracking), and SleepScore (scientific approach). Choose based on your specific needs and desired features.
Understanding Sleep
What is a good sleep score?
A good sleep score typically ranges from 80-100. Scores above 90 indicate excellent sleep quality, 80-89 is good, 70-79 is fair, and below 70 suggests poor sleep quality. Factors include sleep duration, consistency, deep sleep percentage, and sleep efficiency.
How much sleep do I need?
Adults typically need 7-9 hours of sleep per night. Individual needs vary based on age, activity level, health, and genetics. Use sleep tracking to find your optimal duration by monitoring how you feel with different amounts of sleep. Quality is as important as quantity.
What is sleep debt and how to recover from it?
Sleep debt is the cumulative effect of not getting enough sleep. To recover: gradually extend sleep time by 15-30 minutes weekly, maintain consistent sleep/wake times, prioritize sleep quality over quantity, and use sleep tracking apps to monitor progress. Full recovery can take 3-8 weeks depending on debt severity.
Improving Sleep Quality
How to improve sleep score on Apple Watch?
To improve your sleep score: maintain a consistent sleep schedule, create a relaxing bedtime routine, optimize your sleep environment (dark, cool, quiet), avoid screens 1-2 hours before bed, exercise regularly but not close to bedtime, and use apps like Reverie for personalized insights.
Why is my sleep score low?
Low sleep scores can result from insufficient sleep duration, inconsistent sleep schedule, poor sleep environment, stress, caffeine/alcohol consumption, screen time before bed, or underlying health conditions. Track patterns with sleep apps to identify specific factors affecting your score.
