Hi Marco, excellent panel and conversation, very down to earth to the everyday questions we ask ourselves with all this data. Thank you.

.

I measure 4-5 days a week my HRV with a garmin hrm dual pro heart rate band and eliteHRV (must try yours), and what I do is for 5min sit in the mornings just after waking up while doing nasal breathing 4s/6s inhale/exhale. I do this because I read that it is an exercise that helps to improve your HRV. My question is: is the data and trends valuable if I always use that pattern and keep all variables constant? Or would the data be better if I let go of the breathing pattern and measure breathing naturally?

Another question is whether you have tried Muse Headband to study sleep phases. In the podacst you mention that watches don't actually measure that and that the calculation to approximate it is inaccurate, Muse as such does measure the electrical activity of the brain. I just wanted to know if you know anything about how reliable Muse data can be.

Thanks y saluti,

Antonio
