 Now, let me pause a little bit on this one. When I was in school, I learned that your body temperature was a very good clue to say whether you had hypothyroidism or not or hyperthyroidism. If your thyroid was producing too little hormone or too much hormone, that would affect your temperature. You'd run hot versus cold. Yeah. If you have low thyroid, you run cold. If you run in high thyroid, you run hot. Generally.
