Excellent read. I'm truly thankful to you for opening my eyes behind the truth of wearables! I was totally enagaged with my wearable stats all the time, a total slave, but now I won't be :)

Inoltre, sono curioso: di che parte d'italia sei?

Thoroughly useful article! This is basically how I use my oura ring. I do wear it 24/7 but only because I'd lose it otherwise! I pretty much use it to collect HRV and RHR and then I loop it through HRV4Training. I used to just use a chest strap and take a morning HRV measurement, but I find the oura easier to just pop on and let it do its thing. It's amusing to see some of the claims being made by some of the wearables out there with no basis in anything. On the whoop podcast, for instance, the host (and founder of whoop) was once talking to a professional golfer about his REM data and even me, without any expertise, had to stifle a laugh.

Really interesting read, thanks Marco! I started tracking stats to try to help me manage my ME/CFS, and it's become way too easy to obsess over body battery and stress on my Garmin to the point of it becoming overwhelming.

Of course, the problem with Chronic Fatigue Syndrome is that post-exertional malaise doesn't kick in for one to three days after we've pushed ourselves, by which point it's too late and we've crashed our energy for days, weeks, or even months. Using morning stats are useful to see if my day is likely to be a worse day or a less worse day, but there's also evidence that we don't tolerate higher heart rates and have massively reduced anaerobic thresholds. So a major focus with my pacing is to not let my heart rate get too high, meaning I need to monitor heart rate all day.

I didn't know that activity reduces a watch's ability to monitor heart rate, though activity for me is making a cup of tea or going upstairs *slowly*, which I guess is not to to cause a problem like running or playing tennis would 😁

But, I've read a few of your articles and found them interesting and informative. Honestly, I would *love* a version of HRV4Training (HRV4Pacing ...?) for those of us whose top priority is careful energy pacing (Long COVID and ME/CFS) using your expertise in HRV combined with the scientific research about our misfiring autonomic nervous systems and physiological problems with low anaerobic thresholds and exercise intolerance.

Are there any wearables or technology that is moving in the direction that can tell you if you are moving correctly. Due to ongoing injuries I note that If I move correctly Things hurt less, I'd like to know if there is any thing being developed that could help in that area?

Hi Marco, I have a quick question. I first became interested in HRV as a metric when using my Garmin Forerunner 955, which as you know all too well, takes overnight readings. I have also relatively recently started using the HRV4Training app. I am relatively young (22) and have a resting HR of around 40 on an average day. However, I am seeing very large discrepancies between my garmin HRV readings and my HRV4Training reading. For instance, last night my Garmin told me I had an average hrv of 69 (max of 111), and a health snapshot in the morning gave a value of 107. (This is after a hard workout and late dinner the previous evening). However, my 7-day average on HRV4T is 210ms (garmin 7d avg of 95ms) and today it was 254ms. I wonder if you could explain why my readings are so much higher in the app and what that should mean for my interpretation of such data? Thank you so much and I’m very grateful for all your contributions
