How Apple Series 8 Tracks Sleep

The Apple Watch Series 8 offers a range of health-tracking features, including sleep tracking. The Sleep app on the Apple Watch Series 8 allows users to create sleep schedules and wind-down periods to help them meet their sleep goals. The watch automatically tracks sleep when worn to bed and provides detailed information about sleep patterns, including sleep stages, time asleep, and respiratory rate. While the watch does not require a set sleep schedule, it is necessary to wear it to bed and ensure it is charged to at least 30% for accurate tracking.

The Apple Watch Series 8 offers sleep tracking

The Sleep app on the Apple Watch Series 8 enables users to set up sleep schedules, including Wind Down and Bedtime routines, to help them achieve their sleep goals. It automatically tracks sleep when worn to bed, measuring sleep duration and various sleep stages such as REM, Core, and Deep Sleep. This data is then synchronised with the Health app on the iPhone, where users can access in-depth sleep insights, including time asleep, time in bed, heart rate, and respiratory rate.

One of the key advantages of the Apple Watch Series 8's sleep tracking is its ability to detect different sleep stages. By using advanced machine learning models, the watch can distinguish between REM, Core, and Deep Sleep, providing users with a detailed understanding of their sleep quality. This information can help users identify any sleep issues and make informed decisions to improve their sleep habits.

Additionally, the Apple Watch Series 8 offers a Sleep Focus feature, which ensures a distraction-free environment before bedtime. It limits notifications and simplifies the Lock Screen to help users maintain a consistent sleep schedule. The watch also provides charging reminders, prompting users to charge their device before their Wind Down time to ensure sufficient battery life during sleep tracking.

While the Apple Watch Series 8 provides robust sleep tracking capabilities, it is important to note that it does not measure brainwaves or psychological states. The device focuses on physical metrics, such as heart rate and respiratory rate, to provide insights into sleep patterns and overall health. For those seeking a comprehensive understanding of their sleep, combining the Apple Watch's data with observations about their mental state can provide a more holistic view of their sleep health.

It tracks sleep stages, including REM, Core, and Deep Sleep

The Apple Watch Series 8 offers sleep tracking capabilities, including the ability to track sleep stages such as REM, Core, and Deep Sleep. This feature was introduced with watchOS 9, which is available on the Apple Watch Series 8. The watch uses its accelerometer and heart rate sensor to detect which sleep stage the wearer is in and then displays this information in the Sleep app. This data can also be viewed in the Health app on the user's iPhone, along with additional metrics such as heart rate and respiratory rate.

The Sleep app on the Apple Watch Series 8 allows users to create Wind Down and Bedtime schedules to help them meet their sleep goals. It also automatically tracks sleep when the user wears the watch to bed. In the morning, users can view their sleep data, including the time spent in each sleep stage and their sleep trends over the past two weeks.

Apple has designed its sleep tracking feature with minimal "negative reinforcement". While the device will encourage users when they are meeting their sleep goals, it will not admonish them for missing those goals. This feature is particularly useful for individuals with irregular sleep schedules or those who travel frequently across time zones.

In addition to the Sleep app on the Apple Watch, users can also utilize third-party apps such as AutoSleep for sleep tracking. These apps can provide additional features and customization options for tracking sleep. However, it is important to note that Apple Watch's sleep tracking requires the user to indicate when they are sleeping, and it does not have information about "brainwaves and psychological states".

Overall, the Apple Watch Series 8 offers comprehensive sleep tracking capabilities, including the ability to track sleep stages such as REM, Core, and Deep Sleep. This information can help users gain insights into their sleep patterns and make informed decisions to improve their sleep quality.

Users can create sleep schedules
