Apple Watch Sleep Tracking: What's The Verdict?

what happens if you sleep with your apple watch

The Apple Watch has a range of features that can be used while sleeping, such as sleep tracking, sleep apnea detection, and breathing rate tracking. While wearing an Apple Watch to bed can provide insights into sleep patterns and potential sleep disorders, there are also potential downsides to consider. Some users have reported wrist pain and skin irritation from wearing the watch too tightly, and notifications may disrupt sleep. Additionally, the watch's battery may not last through the night, and users are advised to allow their skin to breathe by periodically removing the watch. Overall, the decision to sleep with an Apple Watch depends on individual preferences and the balance between the benefits of tracking sleep and potential disruptions to sleep quality.

Tracking sleep and sleep apnea

Apple Watch offers a range of features for tracking sleep and sleep apnea. The Sleep app allows users to create sleep schedules and set sleep goals. It can estimate the time spent in different sleep stages, such as REM, Core, and Deep sleep, and display sleep trends over the past 14 days. Users can also set up Sleep Focus, which limits distractions before bedtime and protects sleep. The watch can also track breathing rates during sleep, providing insights into overall health, and detect breathing disturbances that could indicate sleep apnea.

To enable sleep tracking, users can wear their Apple Watch to bed and ensure it has sufficient battery life, typically above 30%. While wearing the watch to bed, users can set it to Sleep Focus mode to silence notifications. Alternatively, users can put the watch in theater mode, which only uses 5-10% of the battery overnight. It is important to note that the watch should not be worn too tightly to avoid skin irritation. Additionally, the watch and band should be kept clean and dry to reduce the possibility of skin irritation.

The watchOS 11 and newer models introduce sleep apnea detection, which tracks breathing disturbances to determine the presence and severity of sleep apnea. This feature is available on the Apple Watch Series 9, Series 10, and Ultra 2, requiring watchOS 11. To set up sleep apnea notifications, users must be over 18 years old and not previously diagnosed with sleep apnea. The watch will analyze data every 30 days, and users can view their breathing disturbances for various periods. However, it is important to note that sleep apnea detection does not replace a proper medical diagnosis, but it can prompt users to seek professional help.

Skin irritation

Firstly, sweat build-up can cause skin irritation. This is especially the case if the watch is worn tightly, as this can trap sweat and moisture against the skin, leading to irritation and rash formation. Even a loose-fitting watch can cause irritation, as sweat, dirt, and bacteria can accumulate underneath it over time. This is exacerbated by insufficient cleaning of the watch.

Secondly, friction can also lead to skin irritation. This is more likely to occur if the watch fits too tightly or loosely, as this can cause rubbing against the skin.

Thirdly, sensitivity to certain materials, such as metal or silicone, can cause skin irritation. Nickel sensitivity is a common cause of allergic contact dermatitis, which is a true skin allergy. Other materials to watch out for include rubber, which can cause irritation for those who sweat while wearing it, and stainless steel, which often contains nickel.

To prevent skin irritation, it is recommended to wear the watch loosely to allow for better air circulation and to minimise friction. It is also important to clean the watch and band regularly with mild soap and water to remove any sweat, dirt, or bacteria. Choosing watch bands made from hypoallergenic materials or those labelled as suitable for sensitive skin can also help prevent irritation.

If skin irritation does occur, it is recommended to remove the watch and clean the affected area with mild soap and lukewarm water to eliminate any potential irritants. Moisturising the skin with a thick, petroleum-based moisturiser can help soothe and hydrate the area. If the irritation is accompanied by significant itching, an over-the-counter hydrocortisone cream can be used to relieve discomfort. It is also important to keep the area dry and avoid wearing the watch until the irritation improves. If the irritation does not improve within a few days or worsens, it is advisable to consult a dermatologist for further evaluation and treatment.

Wrist pain

Many users have reported experiencing wrist pain after wearing an Apple Watch. This pain can be deep and radiate up the arm, and may be caused by pressure on the ulnar nerve. The pain can also be accompanied by a rash, and may be worse when the watch is worn at night. In some cases, the pain has been so severe that users have had to stop wearing their Apple Watch altogether.

There are several strategies that can be adopted to alleviate wrist pain caused by wearing an Apple Watch. Firstly, it is important to adjust the fit of the watch band so that it is neither too tight nor too loose, and sits comfortably on the wrist without causing pressure or excessive movement. Wearing the watch on the opposite wrist can also help to distribute pressure and reduce strain on the affected wrist. Additionally, it may be beneficial to reduce the amount of time the watch is worn, especially at night, as this can allow the wrist to recover and reduce the risk of long-term nerve damage.

Some users have also found relief by using EMF radiation protection products, such as the BioBand, which is designed to minimise EMF exposure while still allowing access to the Apple Watch's features. Other temporary solutions include placing a band-aid or skin tape over the sensor to block the "rays", and turning off certain features such as the heart rate monitor and haptics.

It is important to note that wrist pain may also be caused by other factors, such as sleeping with the watch on or wearing it too high up on the wrist, which can result in constant contact with the delicate pisiform bone. Therefore, it is recommended to wear the watch slightly lower on the arm, and to avoid wearing it too tightly.

Battery life

Apple Watch users have reported that the device's battery life is insufficient to last a full 24-48 hours, especially when using sleep tracking. This has led to concerns about the practicality of using the Apple Watch for sleep monitoring.

To address this issue, Apple has introduced longer battery life in newer models, such as the Apple Watch Series 7, 10, and Ultra, which offer faster charging speeds. For example, the Apple Watch Series 10 can be charged to nearly full power in around 30 minutes.

Additionally, there are several hidden settings that can help extend the battery life of your Apple Watch. One such setting is 'Sleep Mode', which is automatically enabled when you create a sleep schedule. This mode limits battery drain by silencing all notifications during the scheduled sleep period. To enable Sleep Mode, swipe up on the Control Center and activate it.

Another way to conserve battery power is to manually adjust the settings for notifications and apps. For instance, you can open the Settings, go to Sounds & Haptics, and set the Alert Volume to maximum. This will ensure that your alarm still sounds even if Silent Mode is enabled. Additionally, you can disable the 'Raise to Speak' feature for Siri by going to Settings > General > Siri and toggling the option off. Similarly, you can disable the background app refresh for specific apps by opening the Watch app on your iPhone, navigating to the My Watch tab, selecting General > Background App Refresh, and toggling off the apps you don't want refreshing in the background.

By utilizing these settings and taking advantage of the faster charging speeds on newer models, Apple Watch users can better manage their battery life, making it more convenient to wear their device overnight for sleep tracking and other features.

Notifications

Sleep Focus mode can be set up in the Health app, where you can also create sleep schedules to help you meet your sleep goals. You can set your next bed and wake-up times, and even create multiple schedules, such as one for weekdays and another for weekends. For the sleep schedules you set, Sleep Focus helps reduce distractions before and during bedtime by filtering out notifications and phone calls.

If you're using an Apple Watch Series 7 or later, or an Apple Watch Ultra, you can also set charging reminders to notify you when your watch is fully charged. However, it's worth noting that even if you silence your notifications, your Apple Watch will still use some battery power at night, especially if it's tracking your sleep. So, if you have an older Apple Watch model that doesn't charge as fast, you might find yourself running low on power in the morning.

In addition to notifications about your sleep schedule and charging, the Apple Watch can also provide notifications related to your health. With watchOS 11, your Apple Watch can track your breathing rate and detect breathing disturbances while you sleep. If it detects consistent signs of moderate to severe sleep apnea over a 30-day evaluation period, you'll receive a notification suggesting you seek medical advice. It's important to note that while these notifications can be helpful, the Apple Watch is not a medical device and cannot replace a proper medical diagnosis.
