3. When you at times feel too cold or too hot at times.
The thyroid in one’s body acts as the thermostat to measure and regulate the body temperatures. When this hormone under-performs, an individual might feel chilled out. When the hormone over-functions, an individual might tend to feel overheated when in a normal room temperature and at times one is comfortable when others are freezing out. So, when you feel too cold or too hot especially under normal temperatures, you should get a thyroid check.
