Are being healthy and not unhealthy the same thing? For example not smoking is "not unhealthy" in the sense it does not hurt your lungs, but I would not consider standing around not smoking as being healthy. Similarly drinking water is not unhealthy compared to the harms of soda and dehydration. The traditional form of healthy is avoiding harm; avoiding less than normal health. Ice baths and fasting seem like an attempt to be above the baseline normal healthy. Its an addition instead of avoiding a subtraction.
