I think these things are geared to athletes, not people with chronic fatiguing illness..... I have been wondering how your experiment (maybe this should be added to this thread: https://forums.phoenixrising.me/threads/poll-experimentation-win-lose-draw.85268/ or this one:https://forums.phoenixrising.me/thr...rk-in-the-long-run.85267/page-2#post-2362615?) with HRV was going. Sorry to hear you have had so little help from it. I know you were hopeful.And I've gotten a 10 on days that I am crashed!
Considerably higher HRV levels are not necessarily a good thing. These may be an indication of low autonomic nervous system stimulation, which can be felt as low energy and lethargy.
HRV is a measure of inter-beat variability, a.k.a. the R-R intervalHeart rate variability is measuring the difference between individual heart beats right?
