The Samsung Galaxy Watch 4 and Watch 5 are Android smartwatches that run on Wear OS. Both smartwatches feature sleep tracking with detailed insights on sleep stages. In this article, let’s see how sleep tracking works on Samsung Galaxy Watch 4 and 5, understand different sleep stages, how to enable the feature and related queries.
How Does Sleep Tracking Work on Galaxy Watch 4 and 5?
The Galaxy Watch 4 and 5 use the built-in accelerometer motion sensor to detect body movements and its own software algorithms. These watches also use the BioActive sensor to record heart rate, SpO2, and other health data for better sleep-tracking accuracy.
When you go to sleep, and your body enters the resting state, the watch detects that your body movement is stopped and you are resting. As soon as you enter the sleep cycle, it starts detecting the sleep stages, including awake, light sleep, deep sleep, and REM. The watch shows eight different animal symbols to represent your sleep type.
Along with the sleep stages, you can also enable snore detection on your Galaxy Watch 4 and 5. The watch should be connected to your phone as it uses its microphone to record snoring. And it can also measure blood oxygen during sleep, which can help you record your breathing during sleep.
