How to Understand Your Sleep Tracking Report
Focus on trends in time asleep, bedtime consistency and how you feel, not on nightly scores or stage percentages. If a report worries you, talk to a doctor; do not self-diagnose.
Key points
- What to read. Weekly averages of sleep time and the regularity of bed and wake times are the most useful numbers.
- What to treat cautiously. Stage breakdowns, readiness scores and single-night results can mislead.
- Orthosomnia. Over-focusing on tracker data can increase anxiety and worsen sleep; if the numbers stress you, take a break from tracking.
