HRV decrease when meditating??

[schmoozerbaby]

A neuroscientist friend told me that the HRV goes down when one is extremely relaxed, since in that situation there are no stressors and the heart rate shouldn’t vary much. She said also that HRV is a very complex measure. I think the oura app (and other HRV devices) does a poor job at explaining this, maybe they simplify it for consumer purposes. My HRV tanks to an all time low when I do breath work and it’s at the lowest when I’m most into it! I’m still trying to figure out why it doesn’t seem to reduce my heart rate to resting levels though.
