Sleep Tracking

While you are sleeping, the watch automatically detects your sleep and monitors your movement during your normal sleep hours. You can set your normal sleep hours in the Garmin Connect™ app. Sleep statistics include total hours of sleep, sleep stages, sleep movement, and sleep score. Naps are added to your sleep statistics, and can also impact your recovery. You can view detailed sleep statistics in your Garmin Connect account.
NOTE: You can use do not disturb mode to turn off notifications and alerts, with the exception of alarms (Using Do Not Disturb Mode).
