Not toonly tech savvy but trying to get some resolution. Actually, begging for a resolution. So far you fine people on this heat intolerance thread hit the nail on the head. I am one of the rare birds who has major heat/temp intolerance and I don't sweat anymore. Except maybe from my forehead or hairline and pits. But it's not the way I used to my arms and body don't and now I cannot even go outside. Within seconds/minutes my heart race goes fast and I must hurry back inside to air conditioning. I have very low vitamin D (like 1/3 the minimal healthy amount) and also 1/3 testosterone. Thyroid shows as fine. Pituitary test come back normal.
I want to understand a little more about how you were talking about bad D3 and also about how to possibly resolve.
