Thank you very much for this piece. Not sure if this matters, but in terms of the timing of measurement after moving - would you recommend that HRV be measured immediately after moving positions from lying to sitting? Or leave a little delay, for example, wait in a sitting position for a few minutes and then measure HRV?

Is it normal for there to be large differences between lying and standing, even when hrv4training says that my trend is stable and to proceed as planned? My lying average rmsdd is around 120 but my standing average is around 25? Also when hrv4training shows my average rmsdd in population comparison or monthly summary, is that lying, standing, or both?

The app is super helpful, just trying to understand a little deeper, thanks Marco!

How did you measure the night HRV with the HRV4TRAING APP ?

So if the recommendation is to measure HRV while sitting and measure it first thing in the morning, would it be wise to measure it while sitting on the toilet, right after waking up? Asking for a friend.

This was very informative, thank you. I’m wondering what you suggest for those with POTS - the HRV4 app is recommended widely in the POTS / MECFS community to assist with pacing. In the case of POTS, heart rate goes up significantly upon sitting or standing (in my case usually by around 40-50bpm immediately). Would you suggest taking two measurements, or still sticking with sitting?
