What You'll Learn
Setting up sleep tracking
First, ensure that your watch is charged and ready for use throughout the night. The Samsung Active 2 Watch has a long-lasting battery that can go for more than a day on a single charge. However, it is always a good idea to start with a full battery to ensure uninterrupted sleep tracking.
Next, open the Samsung Health app on your watch. This app is crucial for monitoring your sleep patterns and providing you with insights to improve your sleep quality. To access the app's settings, swipe and tap on "Settings."
Within the settings, you will need to enable specific features for sleep tracking. Start by tapping the switch next to "Blood oxygen during sleep" to turn it on. This feature tracks your blood oxygen saturation, or SpO2, during sleep, providing valuable insights into your body's efficiency and overall health.
Additionally, you can also enable the "Run only when you're at Home" option. This feature ensures that your sleep tracking is activated only when you are at home and in bed. You may need to allow location permissions on your watch or connected phone for this feature to function accurately.
Once you've made the necessary configurations, it's time to wear your watch to bed! The Samsung Active 2 Watch will use its onboard accelerometer to detect movement and user data to help track your sleep patterns. It is recommended to wear your watch correctly, positioned at the width of two fingers above your ulna (the pointy bone on your wrist), for optimal tracking accuracy.
In the morning, you can review your sleep data by swiping left on the watch's home screen until you see the "Sleep tile." Here, you will find various metrics, including your sleep score, sleep time, sleep stages, blood oxygen levels, snore detection, and sleep consistency.
By following these steps, you can effectively set up sleep tracking on your Samsung Active 2 Watch and gain valuable insights to improve your sleep quality and overall wellness.

Viewing sleep data
The Samsung Galaxy Watch Active 2 has built-in sleep tracking analysis, which offers valuable insights on how to get a better night's sleep. The watch uses the Samsung Health app and Sleep tile to monitor your sleep patterns, track your sleep movements, and record your snoring. It also provides sleep coaching options and can control your smart devices, such as your TV, to ensure you don't stay up too late.
To view your sleep data, you can swipe left on the watch home screen until you see the Sleep tile, and then tap it. Here, you will be able to see various data points, including:
- Sleep score: This shows how well you slept, based on a variety of factors, and is given a score between 1 and 100. A higher score indicates better sleep quality.
- Sleep time: This shows your sleep duration in hours and minutes, as well as the calories burned during sleep.
- Sleep stage: This shows how long you spent in different sleep stages, including Awake, REM, Light, and Deep sleep cycles.
- Blood oxygen during sleep: This metric measures blood oxygen saturation, or SpO2, which is an important indicator of your body's efficiency. The watch will show your blood oxygen percentage and the total time your blood oxygen saturation was under 90% during the night.
- Snore detection: This feature records and alerts you to the sounds you make while sleeping, allowing you to see the amount of time spent snoring.
- Sleep consistency: This metric shows the number of days in the current week that you have slept and woken up within your set sleep goals.
You can also access your sleep data through the Samsung Health app on your connected phone. Open the app and tap the Sleep tracker, then swipe to view the data under Snoring, Sleep Score, Sleep Time, Sleep Stage, Blood Oxygen, and Sleep Consistency.

Understanding sleep scores
The Samsung Health app provides a sleep score, which is a number between 1 and 100 that indicates how well you slept. The higher the sleep score, the better the sleep. This score is calculated based on several factors, including:
Total Sleep Time
Sleeping too much or too little will negatively affect your sleep score. Samsung believes that adults should get between 6 and 9 hours of sleep per night.
Sleep Cycles
A sleep cycle usually lasts around 90 minutes and consists of four stages of non-REM and REM sleep. Adults should aim for between 3 to 7 cycles per night for optimal sleep.
Movements and Awakenings
The Galaxy Watch records the percentage of sleep that is interrupted. A figure between 10% and 40% is considered ideal.
Physical Recovery
This factor is directly related to deep sleep, which is often regarded as the physically restorative phase of sleep. It is presented as a percentage, with a figure of 40% or above considered excellent.
Mental Recovery
REM sleep is related to mental recovery. Achieving a figure of 60% or above in this category will contribute to a higher sleep score.
In addition to the sleep score, the Samsung Health app also provides sleep coaching options and daily goals to help you form better sleep habits. It also allows you to control your smart devices, such as your TV, to ensure you don't stay up too late.

Using sleep coaching
The Samsung Galaxy Watch Active2 is a great tool for tracking your sleep and improving your sleep patterns. The watch uses the Samsung Health app to monitor your sleep patterns, tracking your sleep movements and providing a sleep score based on your sleep data. The watch can also measure blood oxygen saturation, or SpO2, which is an important metric for gauging your body's efficiency.
To use the sleep coaching feature on the Samsung Galaxy Watch Active2, you will need to wear your watch for at least seven days and nights. This will allow the watch to collect enough data to provide personalised sleep coaching. The sleep coaching settings can only be adjusted from your phone, not the watch itself.
To get started with sleep coaching, open the Samsung Health app on your connected phone and tap the Sleep tile. From there, tap "Get started with sleep coaching". The sleep coaching program will guide you through the best way to get a better night's sleep, providing tips and recommendations based on your sleep data.
In addition to sleep coaching, the Samsung Galaxy Watch Active2 also offers bedtime mode, which is essentially a Do Not Disturb mode that cancels all audio and vibration alerts except for your alarm. This can help create a peaceful environment for sleeping. The watch can also control your smart devices, such as your TV, to ensure that you don't stay up too late.
By combining the sleep tracking and coaching features of the Samsung Galaxy Watch Active2, you can gain valuable insights into your sleep patterns and make informed decisions to improve your sleep quality.

Troubleshooting
If your Samsung Active 2 watch is not tracking your sleep, there are several steps you can take to try and resolve the issue.
Firstly, ensure that you are wearing your watch correctly. According to Samsung, the watch should be positioned the width of two fingers above the ulna, the pointy bone on your wrist. It is also recommended to wear the watch on the outside of your wrist, tight enough so that it doesn't move downwards when your palm is facing downwards.
Secondly, check that you have enabled the necessary settings in the Samsung Health app. Open the app on your watch, navigate to Settings, and ensure that features such as Blood Oxygen during sleep and Sleep tile are turned on. You may also need to allow location permissions for certain features.
If the issue persists, try resetting your watch. This can be done through a soft or hard reset, and instructions for this can be found on the Samsung website or by contacting their support team.
In some cases, the issue may be related to Bluetooth connectivity. Try turning off Bluetooth before going to bed and then turning it on again in the morning to see if the sleep data is recorded.
Additionally, it is important to note that sleep tracking on smartwatches can be inconsistent and may not provide completely accurate results. No fitness tracker is perfectly accurate, and sleep data should not be used for self-diagnosis. If you require more detailed sleep analysis, consider using a dedicated sleep tracking device or program.
