As the master regulator of your metabolic health, your thyroid plays a direct role in thermal regulation. Thermogenesis, or the creation of heat, is a byproduct of metabolism. As the body metabolizes to produce energy from the energy you consume from food, heat is emitted. Metabolism is complicated, but put simply, when you eat, you’re consuming calories. Calories are a measurement of energy that a specific food provides. Calories (actually formally known as kilocalories which = 1000 calories or 1 Calorie) is the amount of energy needed to raise 1 gram of water 1 degree Celsius. Quite literally, calories are a measure of heat potential a certain food creates. When thyroid levels are low, the metabolism slows down, resulting in lowered body temperatures. As thyroid hormone levels come within the normal range, body temperature follows suit. Low thyroid levels are caused by multiple factors including nutritional deficiencies, stress, and autoimmune disease that leads to thyroid destruction and impaired hormone output.
