Module 4 thoughts

HRV looks at the variations between each heartbeat and is an important tool or piece of information in looking at how our body and nervous system adapts to our ever changing environment. But it is a tool, and like any tool, it is only as good as it's context- we must also check in with ourself and trust our self awareness and our body.

I also found it very interesting that mental/psychological stressors have a greater impact on HRV than physical stressors, and that it isn't necessarily whether HRV is high or low that is important, but rather that it is the fact that it remains stable that shows you are adapting well. I did find it interesting that HRV is the #1 predictor for future MI and the most reliable measure that cardiologists use to predict cardiac outcomes, but I think for the general population (and even me), the simpler the information the more powerful and meaningful it is.
