Hi Gabor, this is a great question. I added two paragraphs to the end of the post based on your feedback, "Low HRV values below 50 milliseconds (ms) signal reduced variability between heartbeats, linked to higher stress levels or health concerns. Higher values above 70 ms or more indicate increased variability associated with better health and relaxation.

Exact thresholds can vary by measurement method and individual factors. Seeking guidance from a healthcare professional or using trusted HRV monitoring tools can provide more tailored insights into your health.

To learn more about the HRV metrics and norms, you may check this review paper published on Frontiers. https://www.frontiersin.org/articles/10.3389/fpubh.2017.00258/full"
