Apple Watch Sleep Tracking: Phone Off, On Or Airplane?

The Apple Watch has a built-in sleep tracker that can monitor your sleep patterns and habits. It can track your sleep stages, heart rate, respiratory rate, and sleep duration. However, to utilize this feature, the Track Sleep function must be enabled, and the watch must be worn for at least an hour each night. This raises the question: does the Apple Watch continue to track sleep if the paired iPhone is turned off? In exploring this topic, we will delve into the capabilities and limitations of the Apple Watch's sleep tracking functionality and how it interacts with the iPhone.

The Apple Watch can track sleep without the phone being on

The Apple Watch can track your sleep without your iPhone being on. The watch has a built-in sleep tracker that can monitor your sleep patterns and provide insights into your sleep habits. This feature is available on WatchOS 8 or later.

To enable sleep tracking on your Apple Watch, simply wear your watch to bed and ensure that the "Track Sleep with Apple Watch" option is turned on. The watch will then automatically detect and record your sleep patterns, including the time you fall asleep, the duration of your sleep, and the number of times you wake up throughout the night. Additionally, the Apple Watch can also monitor your heart rate, heart rate variability, and breathing rate while you sleep, providing valuable insights into your overall health.

The sleep data recorded by the Apple Watch can be accessed directly on the watch itself or by using the Health app on your iPhone. To view your sleep data on the watch, scroll down from the main watch face or swipe up with your finger to access the Sleep app. Here, you can see your sleep stages, time asleep, and sleep schedule settings. The Sleep app also allows you to adjust your wind-down and sleep goal as needed.

It is important to note that the Apple Watch needs to be charged to at least 30% before you go to bed to ensure it has enough battery life to last through the night. Additionally, the watch should be worn snugly on your wrist to accurately collect your sleep data. With these considerations in mind, the Apple Watch can effectively track your sleep and provide valuable insights into your sleep habits, even without your iPhone being on.

Sleep tracking is available on watchOS 8 or later

To set up sleep tracking, open the Health app on your iPhone and tap Browse at the bottom of the screen. Then, tap Sleep > Full Schedule & Options. Here, you can turn your sleep schedule on or off and make any necessary changes. You can also set up a wind-down and sleep goal on your iPhone or Apple Watch. To do this, open the Health app and tap Browse > Sleep > Wind Down or Sleep Goal under Additional Details. Adjust the time, then tap to save your changes.

To view your sleep data on your Apple Watch, scroll down from the main watch face using the Digital Crown or swipe up with your finger. Tap the card with your previous night's sleep data to open the Sleep app, which will show your sleep stages, time asleep, the last 14 days' sleep, and your sleep schedule settings. You can also view this information in the Sleep section of the Health app on your iPhone.

To ensure your Apple Watch has enough battery to last through the night, adjust your charging habits and consider using a portable charger.

The watch needs to be worn to bed to track sleep

The Apple Watch has a built-in sleep tracker that can monitor your sleep patterns and provide insights into your sleep quality. However, to utilise this feature, the watch needs to be worn to bed. This is because the watch uses motion detection and your heart rate to determine when you are asleep and to track your sleep stages.

When setting up your Apple Watch, you can enable the "Track Sleep with Apple Watch" feature. This allows the watch to automatically detect when you are sleeping and start tracking your sleep. The watch will record your total time asleep, the number of times you wake up during the night, your heart rate, and your calorie burn. It will also provide averages for your sleep time over different periods, such as weekly, monthly, and biannual intervals.

To ensure accurate sleep tracking, it is recommended to wear the watch snugly on your wrist. This allows the watch's sensors to properly detect your movements and heart rate. Additionally, the watch should be charged to at least 30% before going to bed to ensure it has enough battery life to last through the night.

By wearing the Apple Watch to bed, you can take advantage of its sleep tracking capabilities. This can provide valuable insights into your sleep patterns and help you understand your sleep quality. With this information, you can make informed decisions to improve your sleep habits and overall well-being.

The watch can monitor breathing metrics and heart rate

The Apple Watch can monitor breathing metrics and heart rate. The watch uses green LED lights to measure your heart rate during workouts and Breathe sessions, and to calculate walking average and Heart Rate Variability (HRV). The Apple Watch Series 4 and later, and all models of Apple Watch Ultra, also have built-in electrodes in the Digital Crown and the back of the watch, which can measure the electrical signals across your heart when used with the Heart Rate app or the ECG app. To use the electrical heart sensor to measure your heart rate, open the Heart Rate app and place your finger on the Digital Crown. This will create a closed circuit between your heart and both arms, capturing the electrical impulses across your chest.

The Apple Watch can also monitor your respiratory rate, which is the number of breaths you take per minute. This can give you insight into your overall health. If your respiratory rate is higher than normal while you are asleep, it could indicate that your lungs are unhealthy. Sleep apnoea can cause your breathing to stop and start abruptly and repeatedly throughout the night. Therefore, keeping track of your sleep respiratory rate can help you ensure that your lungs are healthy.

To track your sleep respiratory rate on the Apple Watch, you must first ensure that sleep tracking is enabled on your watch. Then, you need to wear your Apple Watch to bed, and it will automatically measure and record the number of times you breathe in a minute. To view your respiratory rate, open the Health app on your iPhone or iPad. If you're on your iPhone, tap 'Browse' at the bottom of the screen. Then, tap 'Respiratory', followed by 'Respiratory Rate', and then 'Show More Respiratory Rate Data'. The Sleep entry will show the range of your respiratory rate as you slept.

To track your sleep using the Apple Watch, you must wear your watch to bed. You can set up a sleep schedule during the initial setup if you have already paired your Apple Watch with your iPhone. If you pair your Apple Watch after setup, you can still turn on sleep tracking later. You can adjust your wind-down and sleep goal as needed on your iPhone or Apple Watch. To view your sleep history, open the Health app on your iPhone or iPad. If you're on your iPhone, tap 'Browse' at the bottom of the screen.
