I am bringing this topic up again bc *all of a sudden* just this week, my Garmin Forerunner (which is brand new - only about a month old) is reporting that I am at high levels of stress while sleeping. This was not happening before. This is actually stressing me out! I notoriously don't move when I sleep. I don't drink alcohol. I'm getting good both REM and deep sleep, according to the watch. I'm very active, have a low resting HR and BP. My understanding is that sleep apnea would put strain on my HR, and I'm not seeing that. I'm very confused. Anyone else?
