Thyroid hormone stimulates oxygen consumption. Without thyroid hormone, the body utilizes less oxygen to regulate body temperature. 2. Thyroid hormone is a key component in temperature regulation. Without thyroid hormone, the body must rely on shivering for temperature regulation. This requires more oxygen consumption for ATP (energy) production. 3. Thyroid hormone does not have an impact on metabolic activity or temperature regulation
