Answer 1

Explanation:

Your thyroid affects your metabolism. It makes hormones that affect how fast your whole body works and how it uses energy. Your body uses thyroid hormone to increase your energy and raise your body temperature when needed. For example, that helps replace the heat your body loses when exposed to cold weather.
