Also asked, how does Garmin track REM sleep?
Garmin just launched its advanced sleep monitoring feature with the ability to track and provide data for light sleep, deep sleep, REM (rapid eye movement) sleep, and awake time throughout your evening. According to Garmin's help information, REM sleep first occurs around 90 minutes after you fall asleep.
Similarly, how does my watch know I'm in REM sleep? Most wearable sleep trackers leverage actigraphy, where an actigraph sensor is worn around your wrist. Many smartphone sleep tracking apps, on the other hand, rely on the phone's accelerometer to measure your body movement and assess whether you're asleep or awake.
Simply so, how does Garmin determine sleep stage?
By leveraging the optical heart rate sensor on the device, we can now measure Heart Rate Variability (the time measured between each heart beat) which combined with the accelerometer allows us to determine when you fall asleep, when you wake up, and what level of sleep you are in.
Does Garmin Forerunner 235 track REM sleep?
I have the Forerunner 235, which is a wonderful all-around watch/health tracking device, but it does not track REM sleep so I know that the sleep data is rather inaccurate.
