Apple Watch: Sleep Tracker And Your Patterns Revealed

The Apple Watch has built-in sleep-tracking features that can help you monitor your sleep cycles and patterns. By wearing your watch to bed and using a sleep-tracking app, you can learn about your sleep duration, quality of sleep, sleep stages, disruptions, heart rate, respiratory rate, and blood oxygen levels. To receive sleep data, you must enable the Track Sleep setting on your Apple Watch and ensure it is charged to at least 30% before bed. While the Apple Watch's sleep-tracking features are useful, they may not always provide 100% accurate data.

How to set up sleep tracking on your Apple Watch

The Apple Watch has a built-in sleep tracker, but it can be hard to find and set up. Here is a step-by-step guide on how to set up sleep tracking on your Apple Watch.

Firstly, make sure your Apple Watch is charged to at least 30% before you go to bed. If your Apple Watch is charged less than 30% before bedtime, you will be prompted to charge it. In the morning, you can check how much charge is left by glancing at the greeting.

Secondly, turn on "Track Sleep with Apple Watch" to enable tracking. You can do this by opening the Watch app on your iPhone and tapping the "My Watch" tab. Then, tap "Sleep" and "Track Sleep with Apple Watch" to turn on this setting.

Thirdly, turn on "Charging Reminders" so that your Apple Watch can notify you to charge it before bedtime if your battery is low in the evening.

Fourthly, in the Settings app, you can set up your Sleep Focus. This is optional, but it gives you access to specialised home screens and notification settings that will turn on at bedtime.

Fifthly, set up your Sleep schedule. You can do this by opening the Health app on your iPhone, tapping "Browse", then tapping "Sleep", and following the onscreen instructions. Here, you can set a sleep goal (how many hours of sleep you want to get), your bedtime and wake-up times, and whether to turn on Sleep Focus, which limits distractions before bedtime and protects your sleep after you're in bed.

Finally, wear your Apple Watch to bed. Make sure your Apple Watch is unlocked and, if you have a passcode, turn on wrist detection.

Your Apple Watch will now be able to track your sleep patterns. To view your sleep data, open the Health app on your iPhone or iPad and tap "Browse" at the bottom of the screen. If you're using an iPad, tap the sidebar to open it. Then, tap "Sleep". If you have Sleep saved as a favourite, you can access it from the Summary page in the Health app.

You can also view your sleep data on your Apple Watch by scrolling down from the main watch face and tapping the card in your Smart Stack with the previous night's sleep. This will open the Sleep app, where you can view your sleep stages, time asleep, last 14 days' sleep, and your sleep schedule settings.

Third-party sleep tracking apps for Apple Watch

Apple introduced an integrated sleep tracker in 2020 with watchOS 7. However, the built-in tracker may not have all the features you need to fully track and record every aspect of your sleep. For this reason, you may want to try a third-party sleep-tracking app to get a more complete picture of your sleep patterns.

• AutoSleep: This app automatically tracks your sleep from your Apple Watch. It has no buttons to press, and the Watch app is optional. AutoSleep has no user analytics tracking, advertising plugins, or third-party code. It costs $5.99.
• Sleep Pulse 3: This is a fully-featured standalone sleep app for your Apple Watch. It tracks your heart rate, motion, and sleep view. All the sleep analysis is done on the Watch, not on your phone.
• Sleep++: This app is free, or $1.99 without ads. It tries to gauge both the duration and quality of each night's sleep. It shows you the number of hours you were in bed and gives you a percentage measuring how restless you were during the night. You can also view your sleep information in the Sleep++ iPhone app and opt to sync the data to the Health app.
• SleepWatch: After a one-week free trial, the Premium version starts at $3.99 a month or $19.99 a year. It records and analyzes your overall sleep time, quality of sleep, sleep stages, sleep disruptions, average sleeping heart rate, blood oxygen levels, and any noises you make while asleep.

Sleep tracking accuracy

The Apple Watch's sleep tracking feature is a convenient way to monitor your sleep patterns. It can help you learn how long and how deeply you sleep, and you can also view your sleep history and trends over time. However, it's important to note that these trackers are not always 100% accurate and are best used as a starting point.

To receive sleep data on your Apple Watch, you must enable the "Track Sleep with Apple Watch" setting. You should also ensure your watch is charged to at least 30% before bed and worn for at least one hour each night. If your watch battery dies or is too loose, it may not track your sleep accurately.

The Apple Watch uses various biosignals and algorithms to estimate sleep stages, including movement, sound, heart rate, and on some models, O2 saturation. While it cannot accurately measure sleep stages like a full sleep study or an EEG device, it is a good indicator of your sleep patterns.

When compared to other devices, the Apple Watch has shown varying results. Some users have reported that the Apple Watch records less deep sleep than other devices, while others have found it to be more accurate. In a study comparing 37 devices to an EEG, the Apple Watch was the best performer. Additionally, in a study comparing 11 consumer sleep trackers, the Apple Watch 8 showed substantial agreement with polysomnography, indicating its potential for sleep monitoring.

Third-party sleep tracking apps are also available for the Apple Watch, such as AutoSleep, Sleep++, and SleepWatch, which offer additional features and insights into your sleep patterns. These apps can provide more comprehensive data, including sleep duration, quality, stages, disruptions, heart rate, and blood oxygen levels.

Sleep tracking data

Third-party apps, such as SleepWatch and Sleep++, can provide additional insights into your sleep patterns, including overall sleep time, quality of sleep, sleep disruptions, average sleeping heart rate, and blood oxygen levels. These apps can be synced with the Health app on your iPhone, allowing you to view your sleep data and make adjustments to your sleep habits or set goals.

To ensure accurate sleep tracking data, it is important to wear your Apple Watch comfortably and securely during sleep. Additionally, enabling Charging Reminders can help ensure that your Apple Watch has sufficient battery life to track your sleep throughout the night.

It is worth noting that sleep tracking data may not always be 100% accurate, and it is recommended to consult a doctor and undergo a full sleep study for a more comprehensive understanding of your sleep patterns.

Sleep tracking with Apple Watch vs Fitbit

Sleep tracking is an important feature for many smartwatch users, especially those with irregular sleep patterns. Apple introduced an integrated sleep tracker in 2020 with watchOS 7, allowing users to track their sleep patterns using a combination of the Watch and iPhone.

To track sleep with an Apple Watch, users must enable sleep tracking and wear the watch to bed for at least one hour. The Health app on the iPhone can be used to set a sleep goal and create a customised sleep schedule. The Sleep app on the Apple Watch provides a graph showing the user's sleep history, including the time and percentage spent awake or in REM, core, or deep sleep. The watch also tracks changes in nightly wrist temperature.

However, some users have reported issues with the Apple Watch's sleep tracking feature, including instances of no sleep data despite a full battery and Sleep Focus being turned on. Additionally, the Apple Watch does not detect sleep intervals under four hours, which can be problematic for those with interrupted sleep patterns.

In comparison, Fitbit has been a popular choice for sleep tracking for years. The Fitbit Inspire 2, for example, provides a comprehensive view of sleep, including the duration of each sleep stage, resting heart rate, and temperature. It also provides a sleep score out of 100 to grade sleep quality and recovery, which is a feature lacking in the Apple Watch.

While the Apple Watch has been praised for its automatic detection capabilities, some users have found that it does not capture their naps unless they use a third-party app. In contrast, the Fitbit detects naps and is compatible with any type of phone, making it a more affordable and versatile option.

Overall, both the Apple Watch and Fitbit offer solid sleep tracking capabilities, but each has its own advantages and disadvantages. The Apple Watch may be more appealing to those deeply integrated into the Apple ecosystem, while the Fitbit could be a better choice for those seeking a more affordable, compatible, and comprehensive sleep tracking solution.
