Heh my SO just showed me her Garmin-something tracker log the other day, and it showed her having an hour of deep sleep when she'd been lying on the couch watching TV.
It's also showing various sleep stages whens he knows she's been awake, trying to sleep.

To be fair, people actually aren't that great at detecting when they (or others) are really sleeping. Especially for one's self, it's common to believe that you spent more of the night tossing and turning than you really did, when in reality you actually got some light sleep sprinkled in those periods.
That said, consumer-grade wearable devices are demonstrably not great at this either.
Agreed. But it can't tell if I'm jet-lagged and I wake up 3 hours into my sleep at 2:30 am and lay there still, yet unable to get back to sleep. That is sometimes an 80 sleep score night, when really it should be a 40.
Same here. Sleep tracking is mediocre at best. Some nights I’ve spent hours wide awake but lying down, the watch thinks I was awake for 20 min. Or when I wake up in the morning and read a book or scroll the phone to not wake anyone else up, the watch will usually log it as REM.
But it never showed any naps as actual sleeping time. Until I saw your comment I thought that the garmin would only log sleep overnight and never during the day. Did you have to enable something for it to log naps?
