Temperature seems to have a big impact on HRV.  As I posted before, a very hot bath readily drops my HRV to 1.  Previously I speculated a connection between pushing heart rate to max and an HRV of 1, but since have achieved an hrv of 1 at heart rates well below max and have managed a little hrv, as high as 10, when hitting max heart rate.


On the other end, cold dramatically escalates hrv.  Here is this morning's reading taken at 62F.  And this is after a brutally intense workout the day before yesterday that I'm not fully recovered from.


hrv 89, hr 61.96, min hr 28.00 max hr 127.66
rmssd 322.65, lnrmssd 5.78, sdnn 299.20, nn50 83, pnn50 60.145
Anyone else noticing a dramatic rise in hrv with this chilly winter?

Yes, I have noticed, cold dramatically boosts HRV.  It would be interesting to learn more about why and what the mechanism is and if higher HRV induced this way actually has any health benefit in-and-of itself or not...
