FAQ
Reader questions
Why does my sleep duration sometimes show a gap or incomplete session?
This usually occurs when the watch is not worn consistently or Auto-Start Sleep is delayed. Ensure the Sleep schedule is set, the watch is secure on your wrist at bedtime, and firmware is current to minimize gaps.
Can I track naps using the Apple Watch sleep features?
The Sleep app is optimized for overnight sessions, so naps are not captured automatically. For occasional naps, consider a short recording via the Alarm or third-party mindfulness tools, but rely on the main Sleep dashboard for nightly patterns.
How accurate is heart rate and movement data during sleep?
Apple Watch optical sensors provide reliable trends for heart rate and motion, but they are not medical devices. Minor inconsistencies can occur due to wrist position, fit, or skin perfusion, so view the data as guidance rather than a diagnostic tool.
Will enabling Do Not Disturb affect my sleep data recording?
Do Not Disturb and Sleep Focus suppress notifications and calls but do not stop sleep tracking. Your watch continues to monitor heart rate and movement, ensuring that your nightly session is recorded even when alerts are silenced.
