How to Track Sleep with an Apple Watch?
Step 1: Set Up Sleep Tracking
- On your iPhone, open the Watch app, go to My Watch > Sleep, and tap Set Up Sleep in Health App.
- In the Health app, tap Continue, then follow the prompts to set your sleep goal, bedtime, and wind-down time.
Step 2: Create Your Schedule
- Set your preferred bedtime and wake-up times.
- Add different schedules for weekdays or weekends if you like.
- Use the Next Wake Up Only option to adjust one night without changing all schedules.
Step 3: Wear Your Watch to Bed
- Wear the Apple Watch while you sleep. Tracking needs at least 1 hour of wear to work.
- Make sure the watch fits well, not too tight or too loose, for accurate tracking.
Step 4: Enable Sleep Focus and Charging Reminders
Enable Sleep Focus
- Open Health on iPhone > tap Browse > tap Sleep > tap Full Schedule & Options > turn on Use Schedule for Sleep Focus (Optional: Tap on Manage Sleep Focus in Settings > make the changes)
Sleep Focus limits distractions before and during sleep, simplifies your screens, and can turn on automatically with your schedule.
Turn On Charging Reminders
- Open the Watch app on your iPhone > scroll down and tap Sleep > find Charging Reminders > toggle it on so your watch notifies you to charge before bedtime.
Turn on Charging Reminders in the Watch or Health app so your watch charges before bedtime.
Step 5: Check Your Sleep Data
- On your Watch: Open the Sleep app to see last night’s time asleep and sleep stages.
- On your iPhone: Use the Health app and go to Sleep. Choose daily, weekly, monthly, or six-month views. Tap Show More Sleep Data to see details like REM, Core, Deep, heart rate, respiratory rate, and wrist temperature if you have Series 8 or Ultra.
Understand How Sleep Tracking Works
- Apple Watch Series 3 or later with watchOS 9 or later uses motion and respiration data to estimate sleep stages such as REM, Core, Deep, and Awake.
- The watch uses advanced algorithms that have been validated with lab data to make these estimates.
For deeper insights, consider getting a top-rated sleep app for your Apple Watch.

- Let Sleep Focus control your lock screen and notifications.
