Apple Watch Sleep Tracking Fundamentals
The Apple Watch app and the Watch app on your iPhone enable you to easily set up and track your sleep. You can check how much sleep you’re getting each night by accessing the Sleep section and adjusting your schedule.
Apple Watch sleep tracking utilizes a combination of sensors, including the accelerometer and heart rate monitor, to estimate when you’re asleep and identify various sleep stages, such as REM, core, and deep sleep. It also uses wrist temperature and blood oxygen level monitoring on newer models.
As explained in this Pocket-lint guide, sleep tracking is available on all Apple Watch models starting with Series 3, though newer versions (like the Series 8 and Ultra) offer more advanced data points. Sleep tracking features may vary across different Apple Watch models, so check which features are supported on your specific watch.
To get started, you’ll need:
- An Apple Watch Series 3 or newer
- An iPhone (phone) with the Health app installed for setup and syncing sleep data
- WatchOS 7 or later
- A configured sleep schedule in the Sleep app
With these basics in place, you’re ready to monitor your sleep and rest more intentionally.

A well-managed sleep schedule is crucial for maximizing the benefits of sleep tracking on your Apple Watch. You can easily create and adjust your sleep schedule using the Sleep app on your watch or the Health app on your iPhone.
To set up a new sleep schedule, simply tap “Add Schedule” and choose your preferred bedtime and wake-up time. This helps your Apple Watch determine when to start tracking your sleep and when to gently wake you up.
Customizing Sleep Focus
Sleep Focus on the Apple Watch is designed to help you wind down and reduce distractions as bedtime approaches. To customize Sleep Focus, open the Settings app on your iPhone and navigate to the Sleep section. Here, you can enable features like Sleep Screen, which dims and simplifies your Lock Screen on both your iPhone and Apple Watch.
You can also turn on Show Time to keep the time visible while in Sleep Focus mode, and set a wind-down period to help you start winding down before your scheduled bedtime. Customizing your Lock Screen and Home Screen during Sleep Focus mode further reduces distractions.
Understanding core sleep’s role in physical recovery and mental clarity is key to interpreting Apple Watch sleep stage tracking accurately.Advanced Features and Insights
Once you’ve tracked several nights of sleep, your Apple Watch and iPhone begin to surface more advanced insights.
- Sleep Stages: Newer models break down your rest into REM, Core, Deep, and Awake stages. According to Apple Support, each sleep stage, including awake periods, is displayed in the Health app, and these metrics are visualized over time.
- Heart Rate & Respiratory Rate:
- Your Apple Watch continuously tracks your vitals.
- Wrist Temperature & SpO2 (on Series 8 and Ultra): Useful for detecting illness or recovery trends.
- Integration with Apple Health: Sleep data flows directly into the Health app, where you can compare it with activity, heart rate variability, and mindfulness metrics.
Your time asleep is tracked and visualized using bar graphs in the Health app. You can also access more detailed sleep data, including historical trends and breakdowns, for deeper insights into your sleep quality.
You can also pair your watch with third-party apps, such as SleepSpace and Sleep Cycle. As described in this SleepSpace overview, these apps offer features like sleep coaching, audio experiences, and personalized sleep efficiency scores.
Measuring Respiratory Rate
Your Apple Watch can track your respiratory rate while you sleep. To view your respiratory rate data, open the Health app on your iPhone, tap “Browse,” and select “Respiratory.” Here, you’ll find detailed information about your respiratory rate during sleep, including nightly averages and trends over time.
