Hormones strike again. This time they're causing excess sweating because of the thyroid gland overdoing it on the production of thyroid hormone, a condition known as hyperthyroidism. This little gland is nestled right under our voice boxes in our necks and is responsible for making thyroid hormones that affect a number of bodily processes including metabolism, brain development, breathing, weight and body temperature.
What happens when your thyroid goes wacky and produces too much thyroid hormone? Your body temperature is affected, your heat intolerance rises, and you start sweating more than normal. While sometimes very severe, hyperthyroidism is treatable with medications and/or surgery, and sometimes can even go away without treatment at all.
