I'm curious how the ring detected it in advance? I also discovered my Covid when I looked at my Garmin watch and my resting heart rate was 100, until then I had thought I had too much sun that day.

Some of the metrics were out of whack, I think my average body temp was up along with my resting heart rate both asleep and awake.

It somehow takes all that and gave me a "you might be sick" notification.

How is that predicting in advance though? Sounds like it measured active symptoms like a change in body temp etc. That's not prediction, that's reaction.
