What does your thyrold do?

Answer 1

Your thyroid responds to TSH produced by your pituitary gland by producing T4 (an inactive form of thyroid hormone). It then converts T4 into a mixture of T3 (the active form) and reverse T3 (another inactive form).

Not enough T3 is likely to make you feel too cold at normal room temperatures. Too much T3 is likely to make you feel too hot at normal room temperatures.
