> My health watch always registers a great sleep and recharged "body battery" when I've been almost shivering all night.

Would you mind sharing which watch (model) offers this? I guess a Garmin of some sort?

I think most Garmins have it. I have a Venu 3 and am very happy with it, the killer feature for me is it getting over a week of battery life on a single charge vs the apple watch with it's 20 hours.

I see the same results on both the Vivosmart 4 and the original Instinct. Both Garmin.
