Coldness
The process of burning calories might cause heat. But if you are suffering from hypothyroidism, your metabolic rate will be decreased, thus reducing the amount of heat that you generate. Also, the thyroid hormone might turn up the thermostat at brown fat, a specialized kind of fat that produces heat. In addition, brown fat plays an essential role in keeping your body heat during the cold seasons. That’s why a lower level of thyroid hormones can make you feel cold. So if you have felt colder recently, it would be a symptom of hypothyroidism. [3]
