I know I’ve posted this link in other threads when the topic has come up, but just in case @hern939 didn’t catch it, I think Marco Altini’s work is a reliable touchstone. place to check: https://www.marcoaltini.com/. Right now I use resting heart rate measured over night to help assess changes in wellbeing, rather than HRV. I’ve been doing this for quite a long time and I feel like I have a better understanding of the background (both physiologically and in terms of technical measurement details). But I can see that more people are beginning to use HRV, so may start doing this also with a once a day measurement under controlled conditions.
