What You'll Learn
The accuracy of sleep tracking varies from person to person
The accuracy of sleep tracking on the Samsung Galaxy Watch varies from person to person. While some users have reported that the sleep tracking feature is extremely accurate, others have experienced discrepancies between their actual sleep patterns and the data recorded by the watch.
The Samsung Galaxy Watch uses an onboard accelerometer to detect movement and combines this with user data from its sensor array to determine when and how you are sleeping. It also uses the built-in thermometer to sample body temperature throughout the night, which is used in several other metrics. However, the watch's reliance on movement detection can lead to inaccuracies, especially for individuals who move a lot in their sleep or those who remain still while engaging in activities like watching TV or listening to music in bed.
To improve the accuracy of sleep tracking, it is recommended to ensure that the watch is worn correctly. According to Samsung, the watch should be positioned the width of two fingers above the ulna, the pointy bone on your wrist. Additionally, enabling features like "Run only when you're at Home" and connecting the watch to your phone via the Galaxy Wearable app can provide more context to the data and reduce false sleep recordings.
While the sleep tracking data can provide insights into your sleep patterns, it is important to remember that no fitness tracker is perfectly accurate. Therefore, the data should not be used for self-diagnosis, but rather as a guide to help you understand your sleep habits and make informed decisions about your sleep hygiene.
It is worth noting that Samsung continuously improves its products, and updates to the watch's software and the Samsung Health app may enhance the accuracy of sleep tracking over time.

The watch can track blood oxygen saturation during sleep
The Samsung Galaxy Watch is a reliable and easy-to-use smartwatch that can track your sleep, including the quality and length of sleep, and the factors contributing to a good or bad night's rest. The watch uses an onboard accelerometer to detect movement and combines this with user data acquired from its sensor array.
The watch can also track blood oxygen saturation during sleep. Blood oxygen saturation, or SpO2, is an important metric that indicates how efficiently your blood carries oxygen throughout your body, which in turn can tell you whether you're breathing effectively. The higher the blood oxygen value, the more oxygenated your blood is, which is a good sign of health. However, blood oxygen saturation typically decreases during sleep as breathing slows and physical activity reduces. The Samsung Galaxy Watch models can track this saturation during sleep, and Samsung Health charts this data the following morning. It also provides the minimum saturation percentage and the total time blood oxygen saturation was under 90% during the night.
It is important to note that this data is subject to external factors like temperature and the fit of the watch on your wrist. While it can provide insights into your fitness and wellness, it should not be used for self-diagnosis. If you have concerning data or symptoms, it is recommended to seek advice from a medical professional.
To measure your blood oxygen saturation using the Galaxy Watch, you can follow these steps:
- Launch the Samsung Health app on your device.
- Scroll down and tap on "Blood Oxygen".
- Follow the on-screen instructions and tap on "Measure".
- Place your hand on a table, near your heart, and sit still while the watch takes the measurement.
- Ensure that your watch is positioned correctly on the top of your wrist, not pressing against the bone, and is snug enough for an accurate reading.

Once you have set up the Samsung Health app, wear your watch when you go to bed. The watch will then detect and calculate your sleep patterns, providing insights into your sleep time, score, stages, blood oxygen levels, and snoring data. This information can help you identify areas where you may need improvement and make informed decisions to develop healthier sleeping patterns.
In addition to tracking your sleep, the Samsung Galaxy Watch also offers sleep coaching options. This feature provides guidance and recommendations to help you improve your sleep quality.

Tap "Get started with sleep coaching" and answer a few questions about your sleep habits to receive personalized advice.
While the Samsung Galaxy Watch can be a valuable tool for monitoring and improving your sleep, it is important to note that no fitness tracker is entirely accurate. Individual experiences may vary, and factors such as body temperature and watch placement can influence the accuracy of the data. Therefore, it is recommended to use the information provided as a guide to developing healthier sleeping patterns rather than for self-diagnosis.
