Everyone on here will be way ahead on this, but just to say my daughter (27, 2 years #LongCOVID ) just started using the new #visible app from #makevisible.com and is finding it really helpful making her aware of what things do and don't exacerbate crashes
@nickjeffreys Understanding the importance of HRV has been eye opening for me. I backwards engineered it by using Fitbit data and finding trends only to realize after the fact it is known and used in the wider community! I just started using Visible and feel hopeful that the Pace score might be useful

@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

@Rhyothemis @laurens @nickjeffreys awesome!! Tyvm 🌟🌟

1 thing to note - these videos can give the impression that parasympathetic activation (which reads as high HRV) is always good. If you take daily readings & get a sudden increase in HRV / high parasympathetic tone - that can indicate infection or recovery from heavy training. HRV apps / fitness trackers will typically advise a 'recovery day'.

Also, in 3rd video Dr Gervitz says that GI problems are from lacking a brake on sympathetic activity ... 1/

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:

Personal Resonance Frequency Breathing Worksheet

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
