Re: Body temperature regulation.

 Cold intolerance could just as easily be a symptom of adrenal fatigue. You run out of cortisol, and the cells can't utilize T3. It's a classic allopathic catch 22, the patient says that he, or she, is freezing but the thyroid panel comes back normal. The MD refuses to even consider your basal temperature study since you did on your own, and all patients are idiots. Of course, the all knowing MD-God never thinks to test the patient's cortisol.

Don't ask me how I know this.

But this still goes back to hypothyroidism.  Adrenal issues are simply one of the many causes of hypothyroidism.
