Samsung Sleep Tracker: How Does It Work?

Samsung Health's sleep-tracking feature is available on the Galaxy Watch, and it can help you monitor your sleep patterns and sleep movements, as well as track any snoring. The sleep score you receive in the morning is based on the duration of each sleep phase and your movements while asleep. This score can be compared to the scores of users in the same age and gender groups. The watch also measures blood oxygenation levels during sleep. The data is collated and displayed in Samsung Health on your phone and the Galaxy Watch in the form of graphs and charts.

Sleep tracking with the Samsung Health app

The Samsung Health app is a great way to monitor your sleep patterns and track your sleep movements. The app is available on the Galaxy Watch, which you wear to bed to help you keep track of your sleep patterns. The app also provides you with daily goals and coaching programs to help you form better sleep habits.

To use the sleep tracking feature on the Samsung Health app, first make sure that your watch is securely attached to your wrist. Then, open the Samsung Health app on your watch and swipe to Settings. From there, you can turn on features like Blood oxygen during sleep and Snore detection. For the Snore detection feature to work, you will also need to place your smartphone on a stable surface near your head, with the bottom of the phone facing you.

The next morning, you can check your sleep data by swiping left on the watch home screen and tapping the Sleep tile. The Samsung Health app will show you your sleep score, sleep time, sleep stage, blood oxygen levels during sleep, and how much time you spent snoring. Your sleep score is a number between 1 and 100, with a higher score indicating better sleep. This score is based on factors like total sleep time and sleep cycles. You can also view your sleep data in the Samsung Health app on your phone.

In addition to tracking your sleep, the Samsung Health app can also help you improve your sleep habits. The app offers a sleep coaching program that will guide you through the best way to get a better night's sleep. To access this feature, open the Samsung Health app on your phone and tap the Sleep tile, then tap Get started with sleep coaching. You will need to answer some questions about your sleep habits to help determine how best to coach you.

Sleep coaching

Samsung Health's Sleep Coaching feature helps users get a better night's sleep by guiding them through the best way to improve their sleep. The feature is available on the Samsung Health app on the Galaxy Watch, Galaxy Watch Active2, Galaxy Watch3, and Galaxy Watch4 series.

To use the Sleep Coaching feature, users must first wear their watch for at least 7 days and nights. The watch will track the user's sleep patterns, including the quality and length of their sleep, as well as any movements during their sleep. The watch can also detect the user's blood oxygen levels and skin temperature (for the Galaxy Watch5 or higher).

After the initial tracking period, the user will be assigned a "sleep animal" based on their sleep patterns and answers to a survey. The animals include the Unconcerned Lion, Sensitive Hedgehog, Nervous Penguin, Sun-Averse Mole, Cautious Deer, Easygoing Walrus, Alligator on the Hunt, and Exhausted Shark. Each animal represents a different type of sleeper.

Once the user has been assigned their sleep animal, the app will create a four-to-five-week coaching program. This program includes missions, checklists, sleep-related articles, meditation guidance, and sleep reports. The program is tailored to the user's specific sleep needs and provides daily goals and suggestions to help the user form better sleep habits.

Users can also take advantage of the Bedtime mode, which disables all audio and vibration alerts except for the alarm. This mode also disables the always-on display, touch screen to wake, and raise wrist to wake functions. Additionally, the Galaxy Watch can be connected to smart devices, such as the TV, to ensure they turn off at a particular time and don't disturb the user's sleep.

Snore detection

The snoring detection feature on Samsung Health records and alerts you to the sounds you make while you sleep. This feature is only available on the Galaxy Watch4 series. To use this feature, place your smartphone on a stable surface, such as a bed or tabletop, with the bottom of the smartphone facing you. The following morning, you can check your Snore detection data by opening the Samsung Health app on your phone and tapping the Sleep tracker. Swipe to and tap the data under Snoring.

To enable Snore detection, open the Samsung Health app on your watch. Swipe to and tap Settings, and then tap the switch next to Blood oxygen during sleep to turn it on. Next, tap Snore detection. Samsung Health will open on your connected phone; tap the switch at the top to turn on Snore detection.

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, you’ll find a timeline of your latest sleep spell, complete with a sleep stage breakdown on the Y-axis. You can find total sleep stage times below this chart, represented in a bar graph of the total time spent in each stage and the typical range.

Sleep coaching is also available on Samsung Health. To use this feature, open Samsung Health on your connected phone and tap the Sleep tile. Tap Get started with sleep coaching. You'll need to answer some questions about your sleep to help determine how best to coach you.

Sleep data

The Samsung Health app provides a Sleep tile, which allows you to view your sleeping time, record your snoring, and access sleep coaching options. The app also provides a visualisation of your sleep data in the form of a sleep chart, which includes a timeline of your latest sleep spell, a breakdown of sleep stages on the Y-axis, and a bar graph of the total time spent in each stage. The sleep stages are Awake, Light, REM, and Deep sleep cycles. The app also provides a sleep score, which is a number between 1 and 100, with a higher score indicating better sleep. This score is based on five factors: total sleep time, sleep cycles, sleep consistency, blood oxygen levels, and snoring detection.

The sleep tracking feature of the Samsung Health app uses the onboard accelerometer to detect movement and user data acquired from its sensor array. Devices with built-in thermometers also sample body temperature throughout the night, which is used in several other metrics.

Sleep stages

Sleep is a complex process, and understanding your sleep patterns can help you improve your sleep quality. The Samsung Health Sleep Tracker provides a detailed analysis of your sleep stages, giving you valuable insights into your sleep behaviour.

The Sleep Tracker categorises your sleep into distinct stages, including Awake, REM, Light, and Deep sleep cycles. Each stage represents a unique state of sleep, contributing to the overall quality of your rest. By understanding these stages, you can identify areas for improvement and make informed decisions to optimise your sleep.

The Awake stage refers to the periods when you are not asleep. It includes the time you spend trying to fall asleep and any moments of wakefulness during the night. Tracking this stage can help you identify factors that may disrupt your sleep or affect your sleep duration.

The REM (Rapid Eye Movement) stage is a crucial phase of sleep characterised by rapid eye movements and increased brain activity. It is associated with dreaming and memory consolidation. Getting sufficient REM sleep is essential for cognitive function and emotional well-being.

Light sleep is a transition period between wakefulness and deep sleep. While your body and mind are more relaxed than in the Awake stage, you are still easily awakened. Light sleep is important as it prepares your body for the deeper, more restorative stages of sleep.

Deep sleep is the period when your body and brain waves slow down, and you are challenging to rouse. This stage is vital for physical restoration, hormone regulation, and the strengthening of your immune system. Achieving adequate deep sleep can help you feel more energised and refreshed upon waking.

By wearing your Galaxy Watch to bed and enabling the necessary settings, you can access this insightful sleep stage information through the Samsung Health app. The app presents your sleep data in visual formats, such as charts and graphs, making it easier to understand your sleep patterns and make adjustments for a better night's rest.
