“Most sleep tracking devices make some guesstimate as to how much you’re actually sleeping.” For exact data about your sleep habits,
you’d have to do a medical sleep study , which monitors brain waves to analyze the stages of sleep you cycle through during the night.
How accurate is sleep tracking?
So far, research has found that compared to polysomnography tests – which experts use to diagnose sleep disorders – sleep trackers are only accurate
78% of the time when identifying sleep versus wakefulness

How does a smartwatch know you’re sleeping?
Accelerometers. Most sleep trackers measure sleep quantity and quality

How much REM sleep is normal?
On average you’ll go through 3-5 REM cycles per night, with each episode getting longer as the night progresses. The final one may last roughly an hour. For healthy adults, spending
20-25% of your time asleep in the REM stage is a good goal
