3rd year no adverse heat reaction

This is my third year, that the heat has not bothered me at all. Previously it had a devestating impact, not now, not at all. Since having acupuncture along the bladder line, my bladder strengthened in density. Heat energy is omitted from the body through the bladder, if it is comprimised in any way, this cannot happen, therefore we overheat, not everyone falls prey to it, and that baffles me as to why? but for my own personal circumstances it doesnt matter. But it does need to be looked into.
