Let Sleeping Gadgets Lie

I got a Garmin viviosmart hp+ fitness tracker for Christmas, and last year, my partner [personal profile] teaotter got a Polar loop fitness tracker for Christmas. In addition to tracking steps, level of exercise, and for my own device, heartrate, both devices also track how you sleep. [personal profile] teaotter mentioned that her device divided sleep into restful and non-restful sleep and that she regularly got 6.5 hours of restful sleep a night. My device divides sleep into light and deep sleep and says that I regularly get 1.5-2 hours of deep sleep a night. This concerned me a bit, so I wore both devices for sleeping. My said I got 1.75 hours of deep sleep and 6.25 hours of light sleep, but [personal profile] teaotter's said I got a bit less than 2 hours of non-restful sleep and a bit more than 6 hours of restful sleep. I find that data quite reassuring from a health perspective, but rather less so from the perspective of finding such devices to be remotely accurate.

Considering how often it was buzzing until I got you to turn the sound off, I can't be sure it wasn't waking you up every hour or so during the night. Which would account for the restlessness...

It almost sounds like one of them has the numbers reversed. But it may only be inaccurate, as you say. I've been tracking my sleep, but not with a device; solely based on the time I go to bed and get up, plus some adjustments for how long it took me to fall asleep (estimated) & if I woke up a lot.

I wonder what it considers to be the characteristics of "restful" sleep. I doubt it's a 1-1 correspondence with "deep".
