Hi all, 52/F, have had a Forerunner 255 for awhile but just last summer started wearing it all the time instead of just running. HRV "baseline" range was 28-35ish. About a month after establishing all the baselines I got injured and didn't run for a couple of months. Ran sporadically from November until last week. Kept up the strength training and Peloton rides. Also went into late perimenopause and started HRT at the end of November. Numbers still remained about the same, except for about three weeks last month when I got literally zero sleep and was an anxious, nervous wreck day and night. Became "unbalanced". Figured out it was mountain cedar allergies, started antihistimines, no longer a wreck and I actually sleep pretty well now. HRV went back up. Hormones have settled, and I've finally gotten back into a consistent running and gym routine again. This past week was my first full-ish week back, and my HRV has been in the mid 20s all week and I'm now unbalanced. I"m chalking that up to needing to get back into shape.
Here's the question - and no, I'm not obsessing about the numbers, I'm more curious. I've noticed on my graph that my HRV is noticeably lower specifically in the first half of the night, as are my stress levels (still "resting" levels tho). Second half of the night HRV trends back up, and stress levels drop. That super-low (I tanked to 14 the other night within an hour of going to sleep) HRV drop really impacts my average. My overall stress levels are low, I don't drink, and I have non-heavy dinners around 6 PM. Not really doing anything to wind myself up before bed (did watch the Traitors finale last night lol).
Any thoughts? I feel like I'm handling the "strain" of increased distance pretty well, although I don't really have a baseline since I haven't had any numbers like these to look at since I started running 15 years ago.
Thx!
