What brand is your ring? I know some doctors that would love that!

Likely an Oura Ring: https://ouraring.com/

It sounds like one of the better sleep trackers (and not just sleep) if you aren't bothered by the whole "send detailed and continuous personal information to the cloud" thing. I'd recommend staying away from that kind of thing, though..

I have a "Wellue Checkme O2 wrist oxygen monitor". (The Oura ring didn't measure blood oxygen back then.)
