What can my sleep data tell me about why I’m not sleeping well?

Sleep tracking can provide useful clues about why you are not sleeping well when you look beyond a single score and examine how several measurements fit together. Total sleep time, sleep latency, awakenings, sleep efficiency, oxygen patterns, heart rate, HRV, movement, and estimated sleep stages can each add context to what happened during the night. The most useful insights often come from seeing when multiple signals change together and whether the same patterns repeat over several nights. These patterns are not a diagnosis, but they can help you identify whether your sleep is being disrupted, whether oxygen instability or repeated awakenings may be involved, and what specific information may be worth discussing with your doctor.
