Thank you for your insights Marco, always appreciate them! I recently got a Garmin watch and HRV was one of the many things I wanted the watch and its analytics to help me with. I had downloaded and used (not frequently I must admit) the HRV4Training app, since I wanted to get familiar with its use and applications to use with my athletes. However, as I mentioned, I wasn't too diligent with it (I wake up kind of in a hurry every day to coach an early class). Anyway, I think the HRV status from Garmin is pretty useful, albeit imperfect as you mention, since it may consider some "extra" information from the entire night, but the average of the whole night would still change from night to night based on suppression from stress. I realize sleeping HRV may be less useful than sitting or standing HRV after sleep, but I believe you can still notice the same patterns and signals (although they might be a little less clear because of the noise). Maybe I'm just trying to justify myself, what do you think?
Thank you Marco a very interesting and balanced perspective. I am fascinated by my bodies response to stressors particularly the differences created by physiological vs pathological stimulus as I try to age gracefully. It’s been an evolving journey as I have moved from a purely knowledge based perspective to a more wisdom based one creating a more appreciative interpretation. Marco you have been a valuable guide for me on that journey. Sam wearables of any brand provide so much more than HRV data, they even tell the time I wouldn’t be without mine.
Issues with continuous heart rate variability (HRV) measurements

Thank you Marco for this blog. It's very useful read.
Why do you push for hrv then? ;)
Grateful for this blog, Marco.
Thanks. Really helpful.
This post has convinced me to pass on the purchase of a $350+ Garmin watch that captures continuous HRV data.
Informative as ever on the stress response & recovery. Will you do any additional work on the "DFA alpha 1" for workout monitoring?
