Smartwatches: Tracking Sleep And Providing Insights

what watch tracks sleep

Sleep trackers are devices that monitor your sleep patterns and provide insights into your sleep quality. They can be in the form of smartwatches, smart rings, or mats that go under your bed. While no commercially available sleep tracker can perfectly analyse your sleep, they can help identify trends in your sleep, monitor your heart rate and activity, and offer guidance on improving your sleep and fitness. Some popular sleep trackers include the Apple Watch, Google Pixel Watch, Garmin Forerunner 165, and the Oura Ring. These devices offer features such as sleep stage tracking, heart rate monitoring, and sleep goal setting to help users understand and improve their sleep habits.

Apple Watch Series 10

The Apple Watch Series 10 offers several improvements over its predecessor, the Series 9. The watch has a larger, brighter, and thinner display. It also features a polished jet black finish, a new S10 chip, and a faster charging rate.

One of the key new features of the Series 10 is its FDA-cleared sleep apnea detection. This feature allows users to track their breathing disturbances while they sleep and provides information about breathing disturbances throughout the night, which can then be taken to a doctor for evaluation. The data can be viewed on a one-month, six-month, or one-year timeline in the Health app.

The Apple Watch Series 10 also includes the Sleep app, which allows users to create sleep goals and adjust them for weekdays and weekends. The app also includes Sleep Focus mode, which limits distractions before bed and tracks sleep using the watch's motion detectors. It estimates the time spent in each sleep phase: REM, core, and deep sleep.

In addition to sleep tracking, the Apple Watch Series 10 offers other health and fitness features, such as tracking sleep cycles, blood oxygen levels, and body temperature. It also has Wi-Fi, Bluetooth, GPS, and/or cellular options, dust and water resistance, and a longer battery life of up to 18 hours.

To use the sleep tracking features on the Apple Watch Series 10, it is recommended to ensure that the watch is charged to at least 30% before bed and worn for at least one hour during sleep. The Sleep app on the watch can then be used to view sleep data, including sleep stages, time asleep, and sleep duration for the last 14 days.

It also includes a multipath heart rate sensor that captures more accurate heart rate tracking during vigorous activities. The watch can alert you during periods of abnormally high and low heart rate throughout the day and can identify physical signs of stress, excitement, and the effects of caffeine.
