It isn't, as answered elsewhere. When I mean unconsciously, I mean being unaware in that moment. However reflective hindsight reveals not only correlations in habit, behaviour, and so on but also in hindsight from a calmer frame of mind you can be aware of just how anxious you had become. Solely based on HRV would be daft. I'm saying it correlates strongly with many other indicators which together are an indicator of my anxiety, realised or not, at that moment. Ad HRV is a number and other indicators are not, its a great way to have a more quantitative measure which I've found is very helpful. Anecdata and qualitative measures sure, but it works for me.
