Samsung Health can track your sleep through a connected wearable device, such as a Galaxy Watch. The watch uses an onboard accelerometer to detect movement and pairs this with user data acquired from its sensor array. The next morning, you can check your sleep data by swiping left on the watch home screen until you see the Sleep tile. You can then view your sleep score, sleep time, sleep stage, blood oxygen levels, snore detection, and sleep consistency. This data is also available in the Samsung Health app on your connected phone. It's important to note that sleep data should not be used for self-diagnosis, but rather as an insight into your fitness and wellness.

The meaning of sleep scores
Sleep plays a crucial role in our physical health and overall well-being. Samsung Health, in conjunction with the Galaxy Watch, offers users the ability to track their sleep patterns, monitor sleep movements, and receive a sleep score. This data is intended to help users develop healthier sleep habits.
The sleep score is a numerical value between 1 and 100 that indicates the quality of sleep. A higher score denotes better sleep. Samsung does not provide a descriptor for the number, but it does offer the average sleep score for your age group for context. The sleep score is influenced by five factors:
- Total Sleep Time: Sleeping too much or too little can negatively impact your score. Samsung suggests that adults should aim for between 6 and 9 hours of sleep per night.
- Sleep Cycles: A typical sleep cycle consists of four stages: Awake, Light, REM, and Deep sleep. A complete cycle usually lasts around 90 minutes, and adults should aim for between 3 to 7 cycles per night for optimal sleep.
- Sleep Consistency: This factor considers the number of days in a week that you achieve your sleep goals, promoting a consistent sleep schedule.
- Blood Oxygen Levels: The Galaxy Watch can monitor your blood oxygen saturation during sleep, providing insights into your sleep quality and overall wellness.
- Snore Detection: The watch can detect and record snoring, which can be helpful for those who snore or have sleep partners who snore.
It's important to note that the sleep score is a simplified representation of your sleep quality and should not be solely relied upon for medical diagnosis. Samsung Health provides additional data, such as sleep stage breakdowns and sleep charts, for a more comprehensive understanding of your sleep patterns.

Sleep stages and cycles
Sleep is an important factor in our everyday lives. Good sleeping habits play a major role in physical health and overall well-being. Samsung Health can track your sleep through a connected wearable device, such as a Galaxy Watch. The watch uses an onboard accelerometer to detect movement and matches this with user data acquired from its sensor array. Devices with built-in thermometers also sample body temperature throughout the night, and this data is used in several other metrics.
The sleep data is analysed and the user can review key sleep statistics and how much time they spent in each sleep stage. The four sleep stages are Awake, Light, REM, and Deep sleep cycles. 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.
The Samsung Health app provides a sleep score, which shows how long you spent sleeping. This score is given out of 100, with a higher score indicating better sleep. The score is based on five factors: total sleep time, sleep cycles, sleep consistency, blood oxygen levels, and 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 sleep. Under the sleep chart section, you’ll find a timeline of your latest sleep spell, complete with a sleep stage breakdown. 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.

Blood oxygen levels
Wearable devices, such as the Samsung Galaxy Watch, can monitor blood oxygen levels. However, it is important to note that these devices are not medical devices, and their readings may not be entirely accurate. To ensure accurate measurements, it is recommended to wear the watch tightly on the arm, clean the sensor, and remain still during the reading.
Low blood oxygen levels during sleep can be a cause for concern and may indicate underlying health issues such as sleep apnea, sleep-related hypoventilation, or certain medications. Sleep apnea, for instance, can cause the throat to collapse during deep sleep, blocking airflow to the lungs and resulting in decreased oxygen levels.
If you consistently notice low blood oxygen levels or experience symptoms such as daytime sleepiness, headaches, or snoring, it is recommended to consult a doctor. They may suggest a home sleep test or a medical-grade pulse oximeter to monitor your oxygen levels and breathing patterns during sleep.
In summary, while wearable devices like the Samsung Galaxy Watch can provide insights into your blood oxygen levels, it is important to interpret the data cautiously and seek professional medical advice if you have any concerns or persistent abnormalities in your readings.

Snoring detection
Samsung Health's snoring detection feature is a useful tool for those who want to monitor their sleep patterns and improve their sleep habits. The feature is available on the Galaxy Watch, which can be paired with a mobile device for more detailed sleep data.
To enable snoring detection, users must first open the Samsung Health app on their watch and navigate to the Settings menu. From there, they can tap on "Snore detection" and follow the prompts to turn on the feature. The watch must be securely attached to the wrist during sleep, and the phone should be placed near the head on a stable surface, such as a nightstand.
The snoring detection feature records and measures the amount of time spent snoring during sleep. It also allows users to review their snoring data the next morning by opening the Samsung Health app on their phone and tapping on the Sleep tracker. This information can be used to gain insights into sleep quality and make any necessary adjustments to improve sleep habits.
Additionally, users can choose to record audio of their snoring by enabling the "Record audio" option in the Snore detection settings. This can provide more detailed information about snoring patterns and intensity. Users can also set the frequency of snoring detection, such as "Always" or "Once", and specify how long they want to store the audio recordings.
It is important to note that enabling the Snore detection feature will increase phone battery consumption. Therefore, it is recommended to have the phone connected to a charger during sleep when using this feature. By utilising the snoring detection and sleep monitoring features of Samsung Health, users can gain valuable insights into their sleep patterns and take steps towards improving their sleep quality and overall well-being.
