Samsung Gear S3: Sleep Tracker Explained

The Samsung Gear S3 is a watch that can help you monitor your sleep quality and patterns. The watch has a sleep-tracking feature that is completely automatic. Before going to sleep, you can set up your goals by registering your device and setting your bedtime and wake-up time. Once you're ready for bed, simply wear your watch and it will automatically track your sleep once you fall asleep. After you wake up, you can sync your watch with the Samsung Health app to view your sleep stats, including the time you slept, a sleep rating in percentage form, and a graph of your deep and light sleep periods.

Sleep tracking without connecting to a phone

The Samsung Gear S3 watch's sleep tracker, in conjunction with the Samsung Health app, can help you determine if you have been experiencing interrupted sleep. When your tracker is on silent or sleep mode, and there is no body movement, it will be detected as you sleeping. Conversely, if the tracker detects any body movement, it will be recorded as restless sleep. These movements may be caused by your typical tossing and turning or by sleeping problems such as apnea and restless leg syndrome. Additionally, the Samsung Gear S3 can track your sleep automatically. Simply wear the watch to bed, and it will detect when you fall asleep and when you wake up. It will also provide a rating of your sleep quality in percentage form and a sleep graph showing your deep and light sleep periods.

To use the sleep tracking feature on the Samsung Gear S3, there are a few settings you need to adjust. Firstly, ensure that your watch is in silent mode to avoid any disturbances. Then, set up the REM sleep cycle monitor to maximize its functionality. Open the Samsung Health app and look for the Heart Rate option. Tap on it, then tap on the three-dot menu in the top-right corner. After that, tap on the Gear icon, find Settings, and enable the Always option. It is important to note that Samsung has recently updated its sleep tracking capabilities to include REM cycle monitoring. Therefore, if you have this update, simply switch it on before going to sleep.

To track your sleep without connecting to a phone, you can use third-party apps designed for sleep tracking with Samsung watches, such as Sleep as Android. This app is designed for models running Tizen OS, and you will need to have the Gear companion app installed on your watch. However, it's important to note that some users have reported issues with the app, including difficulties connecting and high battery drain.

Alternatively, you can use the Galaxy Wearable app and enable Goodnight mode. To do this, open the Galaxy Wearable app on your phone, find and tap the Home menu, tap the Advanced menu, and switch on Goodnight mode. Remember to disable Goodnight mode manually when you wake up.

Sleep cycle tracking

The Samsung Gear S3 watch, along with the Samsung Health app, can help you track your sleep cycles. The watch automatically tracks your sleep once you fall asleep. It detects when you've fallen asleep and when you wake up, and it also shows your sleep rating as a percentage. It also provides light and deep sleep graphs. For more detailed information about your sleep quality, you can open the Samsung Health app, which provides results for light, deep, and active sleep.

To track your REM sleep cycle, you need to tweak the heart rate settings in the Samsung Health app. Go to the Heart Rate option, tap on it, then tap on the three-dot menu found on the right, tap the Gear icon, find Settings, and select the Always option. Additionally, you can set up the REM sleep cycle monitor to maximize its function.

The Samsung Health app also displays sleep stage data in chart and graph form. Under the sleep chart section, you can find a timeline of your latest sleep spell, along with a sleep stage breakdown on the Y-axis. It also shows the total sleep stage times in a bar graph, representing the time spent in each stage and the typical range.

The Samsung Health app gives a sleep score, which is a number between 1 and 100. A higher score indicates better sleep. Five factors are considered for this score: total sleep time, sleep cycles, movements and awakenings, physical recovery, and mental recovery.

Sleep coaching

The Samsung Gear S3 is a great device for sleep tracking and sleep coaching. The sleep tracking feature is completely automatic. All you need to do is wear the watch to bed and it will monitor your sleep patterns. In the morning, you can sync your watch with the Samsung Health app to view your sleep stats, including a sleep graph for deep sleep and light sleep periods.

To access the sleep coaching feature, you will need to wear your watch for at least 7 days and nights. The sleep coaching settings can only be adjusted from the phone, not the watch. The Samsung Health app will ask you some questions about your sleep to help determine the best way to coach you. The app provides daily goals and coaching programs based on your sleep data to help you form better sleep habits. It also allows you to monitor your sleep consistency, showing you the number of days in the current week that you've achieved your sleep goals.

The Samsung Health app also includes a snoring detection feature, which records and alerts you to the sounds you make while you sleep. To use this feature, you will need to place your smartphone on a stable surface near your bed with the bottom of the phone facing you. The watch can also detect and record your snoring, compiling the data in the Samsung Health app for you to check the next day.

In addition to sleep tracking and coaching, the Samsung Gear S3 can also help you stick to your sleep schedule by allowing you to control your smart devices, such as your TV, to make sure you don't stay up too late.

Snoring detection

The Samsung Gear S3 watch has a sleep-tracking feature that can be used to monitor your sleep patterns. The watch must be synced with the Samsung Health app to use this feature. The app will then display a breakdown of your sleep, including the rating of your sleep as a percentage and a sleep graph for deep sleep and light sleep periods.

To use the snoring detection feature, you must first enable it in the settings of the Samsung Health app. Place your smartphone on a stable surface, such as a bed or tabletop, with the bottom of the smartphone facing you. The app will then record and alert you to the sounds you make while you sleep, including the amount of time spent snoring and how intense the snoring was. The snoring data is displayed in the Samsung Health app under the Sleep tile, where you can swipe to view the data under Snoring. The snoring data is also available in historical form, allowing you to view data from the past week, 31 days, or 12 months.

It is important to note that the snoring detection feature relies on a tethered smartphone to record audio snippets. The watch itself does not record the audio; instead, it uses its built-in microphone to detect when snoring takes place on the timeline. This audio data is deleted after 30 days.

Sleep data accuracy

The Samsung Gear S3's sleep tracking feature is automatic. Users are simply required to wear the watch to bed and sync with the Samsung Health app upon waking up to view their sleep stats. The app will tell the user when they fell asleep and when they woke up, along with the rating of their sleep in percentage form, and a sleep graph for deep and light sleep periods. For more detailed information, the user can sync the data to the Samsung Health app on their phone.

Samsung Health also displays sleep stage data in chart and graph form for those who want a more in-depth view of their night. Under the sleep chart section, users will find a timeline of their latest sleep spell, complete with a sleep stage breakdown on the Y-axis. Total sleep stage times are represented in a bar graph of the total time spent in each stage and the typical range. The sleep stage data is broken down into Awake and REM. 'Awake' includes "brief periods of awakenings" or moments of "waking up completely," including position changes during sleep. 'REM' is the sleep stage named after the rapid eye movement that occurs, and dreaming also often takes place during this stage.

Samsung also provides a sleep score, a number between 1 and 100 that indicates how good the sleep was, with a higher score indicating better sleep. Five factors are considered when formulating the sleep score: total sleep time, sleep cycles, sleep consistency, blood oxygen saturation, and snoring. Sleeping too much or too little negatively affects the sleep score, with Samsung believing adults should get between 6 and 9 hours of sleep a night. A sleep cycle usually lasts around 90 minutes and is one complete progression of the four sleep stages of non-REM and REM sleep. According to Samsung, adults should have between 3 to 7 cycles per night to achieve a high sleep score. Sleep consistency shows the number of days in the current week that the user has gone to sleep and woken up within their set sleep goals. Blood oxygen saturation is also tracked, with the watch monitoring the minimum saturation percentage and the total time blood oxygen saturation was under 90% during the night. This value is subject to external factors like temperature and the fit of the watch on the wrist. Snoring is also tracked, with the watch recording exactly when snoring takes place and using audio to determine how intense the snoring was.

It is important to note that no fitness tracker is truly accurate, so sleep data should never be used for self-diagnosis. Instead, the data should be used for insight into fitness and wellness. If a user feels sluggish in the morning and their blood oxygen saturation data displays worrying information, they should seek medical advice from a professional.
