Apple Watch 8: Sleep Tracking Explained

The Apple Watch Series 8 offers a range of sleep-tracking features, including the ability to track sleep stages and provide detailed insights into sleeping patterns. The watch can estimate the amount of time spent in REM, core sleep, and deep sleep, as well as track sleep duration and trends over the past two weeks. In addition, the Sleep app on the Apple Watch allows users to create personalized sleep schedules and wind-down routines to help meet their sleep goals and improve their overall health. The watch also includes a Sleep Focus feature, which limits distractions before bedtime. To use the sleep-tracking feature, users must wear the watch to bed and ensure it is charged to at least 30% before sleep.

How to set up sleep tracking on the Apple Watch 8

The Apple Watch Series 8 offers all the sleep-tracking features found on older models, along with more detailed sleep insights thanks to the watchOS 9 update. Here's how to set up sleep tracking on the Apple Watch 8:

First, ensure your Apple Watch is charged to at least 30% before going to bed with Sleep Tracking enabled. The Apple Watch will use the sleep schedule (or Sleep Focus, which you can turn on manually) to know when you might be sleeping. During this time, it uses your movements and your phone usage to detect whether you're sleeping and to estimate when you are in each stage of sleep.

To set up sleep tracking, open the Health app on your iPhone and tap "Get Started" under "Set Up Sleep," then tap "Next." Here, you can set up your sleep goals, such as the number of hours you'd like to sleep, your bedtime, and wake-up times. You can also enable Sleep Focus, which reduces distractions before bedtime by simplifying your Lock Screen and limiting notifications.

Next, set up your Sleep Schedule. Open the Sleep app on your Apple Watch and scroll down to check or set your sleep schedule. You can also do this through the Health app on your iPhone by tapping "Browse" and then "Sleep." Here, you can view data on recent nights of sleep and set your sleep schedule for the future.

Additionally, you can adjust your wind-down time and sleep goal as needed. To do this, open the Health app, tap "Browse," then tap "Sleep." Tap "Full Schedule & Options," then tap "Wind Down" or "Sleep Goal" under "Additional Details." Adjust your time, then tap "Wind Down" or "Sleep Goal" to save your changes.

Finally, ensure that "Track Sleep with Apple Watch" is turned on. You can do this by opening the Watch app on your iPhone, tapping the "My Watch" tab, then tapping "Sleep." Here, you can also turn on Charging Reminders to remind yourself to charge your Apple Watch before bedtime.

With these steps, you'll be able to track your sleep using your Apple Watch Series 8.

How accurate is the Apple Watch 8's sleep tracking?

The Apple Watch Series 8 offers all the sleep-tracking features available in older models, along with more detailed sleep insights thanks to the watchOS 9 update. The watchOS 9 introduces sleep stages to provide users with detailed information about their sleeping patterns. The watch uses its accelerometer and heart rate sensor to detect when the user is in REM, Core, or Deep Sleep. It then displays this sleep stage data in the Sleep app. The Sleep app on the Apple Watch Series 8 also offers a Sleep Focus feature, which limits distractions before bedtime and ensures the user does not wake up.

To get the most accurate results when wearing the watch to sleep, it is recommended to turn on Charging Reminders. The watch should be charged to at least 30% before bed with Sleep Tracking enabled. The user should wear the watch to sleep for at least 1 hour. The user can also create multiple sleep schedules, for example, one for weekdays and another for weekends.

The accuracy of the sleep tracking feature has been tested by The Quantified Scientist on YouTube, who claims that Apple's native sleep tracking is the most accurate. However, some users have reported that the Apple Watch picks up more awakenings during sleep than they were aware of, while other third-party apps tend to show a full night's sleep.
