Setup for sleep tracking using Samsung Health app
If you haven’t done this already, we need to ensure sleep tracking is correctly configured.
First things first, you need to pair the Samsung Galaxy Watch with a smartphone. While you can use sleep tracking independently, a smartphone keeps the results over days, weeks, or even months of sleep tracking.
And that’s a good way of motivating yourself to do better.
To pair your Galaxy Watch with a smartphone:
- Install the Galaxy Wearable app on your phone (Android/iOS)
- Enable Bluetooth
- Open the Galaxy Wearable app with your Samsung Galaxy Watch nearby.
- Pick “Galaxy Watch”
- And complete the pairing process by following the on-screen instructions.
Install Samsung Health app
Once pairing is complete, download and install the Samsung Health app if it’s not already on your phone and watch
- You’ll use this app to monitor your sleep patterns using your Galaxy Watch.
- Once installed, don’t forget to set it up using your Samsung account (or create a new one.)
Turn on automatic heart rate monitoring
- Open the Samsung Health app.
- Scroll down and tap Heart rate.
- Navigate to the bottom of the screen and choose HR and stress measurement or Auto HR settings.
- Turn on Measures continuously or Always to allow your watch to track your sleep stages (REM.)
Turn on Samsung Health’s REM sleep recording
Depending on what Watch model and version of the app you use, you may need to set up this additional setting.
- Open Samsung Health’s Sleep category.
- Swipe and tap the Settings button.
- You may need to tap the three-dot More button on the right and then tap the Settings.
- Toggle on Record REM sleep.
Turn on blood oxygen level monitoring during sleep
Depending on your watch model, it can measure your blood oxygen levels during your sleep. This feature works best when you wear your watch an inch or so above the wrist bone. You want the watch’s sensors to fit snugly against your skin.
- Set up blood oxygen tracking on your watch or phone.
- On your watch, open the Samsung Health app > Settings > Measurement > Blood oxygen during sleep > On.
- On your phone, go to Samsung Health > Sleep > More options > Blood oxygen during sleep > On.
- On your watch, open the Samsung Health app > Settings > Measurement > Blood oxygen during sleep > On.
Set-up snore detection
Samsung Health’s Snore Detection feature records and takes note of the sounds you make while sleeping. This feature uses your phone’s microphone, so you need to be near you when sleeping.
Samsung advises users to place their phone’s microphone so it faces them and picks up any snoring, and identifies how long and how often they snore.
The snoring detection feature is available for the Galaxy 4 watch users with the Samsung Health app version 6.18 and above, so you might need to update Samsung Health to see this setting.
How to turn on snore detection
- On your phone, open Settings > Apps > Samsung Health
- Go to Sleep > More options > Snore detection
- You can also find this option in your watch’s Settings > Measurements > Snore Detection
- Set it to Always on or toggle it on manually for times when you want to track snoring
- Choose to record audio and set how long you want those recording saved
Once you turn snore detection on, wear your Galaxy 4 watch to bed and place your phone on a flat surface, near your head. Once your watch detects that you are sleeping, your phone’s microphone picks up and records any snoring sounds.
See your sleep data using the Samsung Health app and your watch or phone
Wear the smartwatch snugly on your wrist and get a good night’s sleep, then in the morning
- Head to the home screen of your Galaxy Watch and select Samsung Health
- Tap on the sleep icon
- Scroll down and check out your sleep stats, including your sleep score, actual sleep time, and your weekly average sleep time. Keep scrolling to see all the information.
If it’s all working as intended, you should see all of your sleep stats in detail. Your Samsung Galaxy watch tracks 4 stages in your sleep: awake, REM, light sleep, and deep sleep.
No REM sleep tracking?
If you don’t see any REM information and haven’t updated the latest operating system, REM tracking may turn off.
When REM is off, your watch measures your sleep stages through your movements only.
Turn on Record REM sleep by going through the sleep tracking screen’s settings menu
- On the sleep screen, swipe up or down and tap the Settings button.
- Turn on Record REM sleep.
Review your sleep metrics and stats on your paired phone instead of your watch
You can always look at your sleep stats, score, and other metrics on your phone too!
- On your phone, open the Samsung Health app.
- Scroll down and tap Sleep.
- Review your sleep details by scrolling through them.
- Tap on the Sleep Score to see even more details, including how you compare to your same age and gender group, as well as information on best practices.
- To view your sleep history, tap the Trends tab at the top. There are options to view this by day, week, or month.
Interpreting Sleep Tracking
Using sleep tracking means that you are obviously gonna have to wear the watch on your wrist while sleeping.
That’s because smartwatches rely mostly, if not entirely, on movement to analyze your sleep habits.
After a proper night’s sleep, you should get the below results:
- Time in bed: The overall time you spent laying down – regardless of how much of it was while sleeping
- Sleep score: The final score that resembles the overall quality of your sleep for that night by measuring all of your stats
- Actual sleep time: This Shows only how much time you spent sleeping – regardless of how much time you spent on the bed
- Awake: How much time you spent awake while lying on the bed
- REM: The overall time that you spent in the REM stage “Rapid Eye Movement.”
- Light: How much of your sleep was light sleep.
- Deep: How much time you spend in the deep sleep stage
- Typical range: The range of minimum and maximum averages for a healthy adult of your age, gender, and body weight. Typical ranges are identified by the white diagonal lines in the graph.
- Weekly average: How much time you spend sleeping on average every week
And you can also check your results from further back beyond the weekly restriction of the watch by using your phone – which is one of the main reasons we showed you how to pair the watch in the first steps.
What about the sleep score?
It’s worth keeping in mind that the sleep score doesn’t simply reflect how much you sleep. The overall quality of your sleep is just as important as the length.
For example, 8 hours of sleep with very little deep sleep and REM sleep may be lower than 7 hours with sufficient deep sleep and REM sleep scores.
Understanding Sleep Tracking: How Does the Galaxy Watch Track Sleep?
Smartwatches can tell how well you are sleeping by using a variety of different tools. Some of the most popular ones are:
- Movement and positioning: This is pretty self-explanatory. Vast movements indicate that you are awake while standing still after a certain amount of time means that you are going through light sleep
- Sound: Things like snoring and outside noises may be decremental to your sleep quality. Sleep trackers may use such info to calculate your final sleep score
- Heart rate: Our heart rate changes when we sleep and can also change depending on sleep quality. A sudden spike in heart rate, for example, may indicate that you just entered the REM stage or that maybe you are having a nightmare
- AI: The AI of the program can finally process all of the data that it gathers from your sleeping habits and determine how well you sleep in detail
Not to mention that the watch can also use information such as your daily sleeping time and waking up to determine further whether you are sleeping well or not.
It’s worth noting that all the above methods of sleep tracking are general and not exclusive to Galaxy Watches.
At this point, it’s worth pointing out that sleep tracking isn’t always entirely accurate. At no point in life should you replace health experts with a smartwatch, be it for heart wellbeing, sleeping habits, blood pressure, or anything health-related at all.
Smartwatches and other smart devices are always cool and helpful to have. But we are nowhere near the point where we can use them to replace expensive medical equipment and health experts.
How to fix Galaxy Watch sleep tracking issues
Sleep tracking should work automatically out of the box. The only things you need to do manually are pair your smartphone with the watch, enable REM tracking (optional), and always wear the watch while sleeping.
If sleep tracking doesn’t work, here are some of the most common solutions to try out:
- Enable Heart-Rate tracking: After 2018’s update, Galaxy Smartwatches can use sleep tracking without heart-rate tracking. But there is still a chance that yours is bugged. So, try enabling heart-rate tracking first and see if that works.
- Add a manual sleep report: The wearable app allows you to manually add some sleep data, such as when you went to sleep and woke up. Try adding one accurate report and see if the watch starts tracking after that.
- Try rebooting the watch: The exact process of rebooting a Galaxy Watch may differ depending on the model. For the Galaxy Watch 3, hold down both buttons until the “Rebooting” screen comes up. Hopefully, that will fix your problem.
- Unpair and re-pair the watch with your watch: This is unlikely to work, but it only takes a couple of minutes. So, go to the Wearable app and give it a try.
- Perform a factory reset: This is a more drastic approach that will delete everything on your watch. Again, the exact process may differ from watch to watch. To factory reset a Galaxy Watch 3, go to the general settings and hit the “Reset” option at the bottom of the list.
- Wait for it to fix itself: As weird as it sounds, there have been a few reports of people who faced this issue, and it got fixed on its own. So, if you can’t get it to work, maybe give it a couple of days before asking for a return.

What is Goodnight Mode on Galaxy Watch?
As the name suggests, Goodnight Mode is the “Do Not Disturb” feature that you commonly find in smartphones – but for your Galaxy Watch.
It basically disables notifications – which is an obvious necessity when trying to sleep – but does not turn off alarms.
Can you sleep with a Galaxy Watch?
Contrary to certain widespread rumors, there is no scientific evidence to claim that wireless devices are bad for our health. So, as long as the feeling of having a watch on your wrist doesn’t prevent you from sleeping, there is nothing wrong with sleeping with a Galaxy Watch.
If you want to take advantage of sleep tracking, you need to be wearing the watch while sleeping.
Why is the Galaxy Watch Sleep Tracking Accuracy so bad?
The Samsung Galaxy Watch relies a lot on movement to determine when you are sleeping and how you are sleeping.
The thing is that just because you are standing still doesn’t mean that you are sleeping. Many people lay still on the bed to watch TV, Netflix, or listen to music/podcasts.
If the watch doesn’t have available methods of accurately tracking biometrics such as heart rate, it may think that you are taking a nap. Not to mention people who move a lot in their sleep and AI accuracy. So, your mileage in terms of accuracy may vary.
That’s all there is to know about setting up and using sleep tracking on Samsung Galaxy Watch devices.
