What You'll Learn

Troubleshooting tips for fixing sleep tracking
Firstly, ensure that your watch is connected to your phone via the Galaxy Wearable app. This connection is necessary for features like Snore detection, which is accessed through the Samsung Health app. If your watch is not tracking your sleep, check that it is connected to your phone and that the relevant features are enabled in the app.
If you are still experiencing issues, it may be related to your watch's battery life. Some users have reported that their watch's battery life is shorter than the minimum stated by Samsung, which may impact its ability to track sleep. Check your watch's settings and ensure that no battery-draining apps or features are enabled. When you first get the watch, the battery may drain more quickly as it calibrates, so allow for a few charges before concluding that the battery life is insufficient.
Another potential issue could be with the heart rate monitor. Some users have reported inconsistencies with the heart rate readings, which may impact sleep tracking. Samsung has released updates to address this issue, so ensure that your watch is updated to the latest software version.
If you are still encountering problems with sleep tracking, it may be worth contacting Samsung support for further guidance and potential hardware solutions. It is important to note that no fitness tracker is perfectly accurate, so sleep data should be used as a guide rather than for self-diagnosis.

How to use the Sleep tile on the Samsung Health app
The Samsung Health app on your Galaxy Watch can help you keep track of your sleep patterns. The Sleep tile feature will detect and calculate your sleep patterns during the night. To use this feature, you will need to enable a few things in the Samsung Health app.
First, 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. Make sure your watch is connected to your phone via the Galaxy Wearable app to use Snore detection. You can turn on Snore detection by opening the Samsung Health app on your phone, tapping the top of the Sleep tile, tapping the three vertical dots in the upper right corner, tapping Advanced measurement, and then tapping Snoring.
You can also use the Sleep coaching feature to guide you through the best way to get a better night's sleep. To use this feature, you will need to wear your watch for at least 7 days and nights. Open Samsung Health on your connected phone and tap the Sleep tile. Tap Get started with sleep coaching and answer some questions about your sleep to help determine how best to coach you.
The app will provide you with a sleep score between 1 and 100, with higher scores indicating better sleep.

Understanding your sleep score
The Samsung Health app on your Galaxy Watch can help you understand your sleep patterns and quality. The app's Sleep tile feature will display your sleep score, which is a number between 1 and 100, with a higher number indicating better sleep quality. This score is formulated by considering five key factors:
- Total sleep time: Sleeping for too long or too little will negatively affect your sleep score. Samsung recommends that adults get between 6 and 9 hours of uninterrupted sleep per night.
- Sleep cycles: A typical sleep cycle consists of four stages of non-REM and REM sleep, lasting about 90 minutes. Achieving between 3 to 7 cycles per night will contribute to a higher sleep score.
- Movements and awakenings: The Galaxy Watch records the percentage of sleep that is uninterrupted. A lower percentage of interruptions is ideal for a better sleep score.
- Physical recovery: This factor is directly related to deep sleep, which is often considered the physically restorative phase of sleep. It is presented as a percentage in the app, with a higher percentage contributing to a better sleep score.
- Mental recovery: REM sleep is associated with mental recovery. Achieving a higher percentage of REM sleep will result in a higher sleep score.
In addition to the sleep score, the Samsung Health app will also provide detailed information about your sleep time, sleep stages, blood oxygen levels, snoring, and sleep consistency. This comprehensive data will help you understand your sleep patterns and make informed decisions to improve your sleep quality.

Tracking sleep consistency
The Samsung Galaxy Watch is a great sleep tracker. It can monitor your sleep patterns, including the quality and length of your sleep, and the factors contributing to a good or bad night's sleep. To track your sleep consistency using the Galaxy Watch, follow these steps:
First, ensure your watch is set up for sleep tracking. Open the Samsung Health app on your watch, navigate to Settings, and turn on Blood Oxygen during sleep. Make sure your watch is connected to your phone via the Galaxy Wearable app, as this is necessary for certain features, such as Snore detection.
Next, wear your watch to bed. The Galaxy Watch uses its onboard accelerometer to detect movement and combines this with user data acquired from its sensor array. Devices with built-in thermometers will also sample body temperature throughout the night. This data is then used to calculate your sleep patterns.
After a night of wearing your watch, you can check your sleep data. The Samsung Health app collates and displays your sleep data, including your sleep time, score, stages, blood oxygen levels, and snoring data. The app provides a sleep score between 1 and 100, with higher scores indicating better sleep. This score takes into account factors such as total sleep time, sleep cycles, movements and awakenings, physical recovery, and mental recovery.
You can also access more detailed information. The Samsung Health app displays sleep stage data in chart and graph form. Additionally, you can view your sleep consistency by checking the number of days in the current week that you've achieved your set sleep goals. This information can be accessed by tapping "Show on phone" and then swiping up to see all your data.
By following these steps, you can effectively track your sleep consistency using the Galaxy Watch.

How to use the sleep coaching feature
The sleep coaching feature on the Samsung Galaxy Watch 4 can help you improve your sleep quality. To use this feature, you must wear your watch for at least seven days and nights. The watch will track your sleep patterns and provide a sleep score based on various factors, including total sleep time, sleep cycles, movements and awakenings, physical recovery, and mental recovery.
To get started with sleep coaching, open the Samsung Health app on your phone and tap the Sleep tile. Tap "Get started with sleep coaching" and answer the questions about your sleep habits and preferences. The sleep coach will then assign you a "sleep animal" based on your answers and sleep data. For example, if you answer "no" to the question "Do you think you have trouble sleeping at night?", you may be assigned the "Unconcerned Lion."
Once your sleep animal is determined, the app will outline a four-week program to help you improve your sleep. You will receive notifications on your watch after each night's sleep, providing information about your sleep quality. As bedtime approaches, you will also receive missions, checklists, sleep-related articles, meditation guidance, and sleep reports to help you achieve better sleep.
In addition to sleep coaching, the Samsung Health app offers other features to enhance your sleep experience. For example, you can enable "Bedtime mode," which disables audio and vibration alerts, as well as the always-on display and raise wrist to wake functions. You can also control your smart devices, such as your TV, to ensure you don't stay up too late.
