@laurens if you have time, can you tell me a bit more about this (or point me to some links)? I've seen HRV talked about in fitbit, but I still haven't wrapped my head around it and what it can indicate
@trendless @laurens @nickjeffreys
I have a playlist on YT on HRV:

However, according to Florsheim et al. "The extreme state of parasympathetic activity, nausea, aims to protect from toxic substances."

I'm interested in this topic since my daughter was hospitalized for 5 wks w/ intractable nausea & vomiting.
We have tried resonance breathing & it did not work for either of us since we had shortness of breath; we were not breathing too deeply (hyperpnea).
But it works for many ppl & I made a worksheet for finding personalized resonance breathing frequency:

Personalized Resonance Frequency Breathing Open EliteHRV app and choose Biofeedback, then Custom Breathing Set pace according to chart, set hold times to zero and set the timer for 2 minutes Rest at least 2 minutes between paces Easiness Rating is your subjective opinion rating ranging from 1 (...

What I've found works better for me (& I'm lucky in that I can feel the effects immediately) is Andrew Weil's 4-7-8 breathing. He says not to do more than 8 cycles per session. Unfortunately, it does not have same immediate effect on my daughter & it's hard to get her to do things consistently if she does not notice a benefit.
Relaxation techniques in general don't work well after eating; it's best to wait 2 hrs.

@Rhyothemis @trendless @laurens @nickjeffreys not following this convo closely so advance apologies if comment is out of place...
my n=1 experience was abnormally low resting AM HR usually preceded respiratory illness - often noted 3 to 4 days after successive days of over-reaching in training or 1 very hard race day - like 150+ km on arduous terrain & extreme temps
but - found HR was too late as predictor, mood self-evaluation & sleep quality were better metrics
@Rhyothemis @trendless @laurens @nickjeffreys fun videos! thanks!🙏
I always thought of it as when relaxed my heart plays jazz & when activated it plays techno
raced bicycles through 70s & 80s so went from palpation to downloadable Polar monitors
with a resting HR in high 30s had to learn to calm my anxiety for the odd really loud heartbeat when falling asleep
