Thyroid hormone may rise after exercise. Thyroid hormone is an important hormone secreted by the thyroid gland, which can play a role in promoting brain development, nutritional metabolism, physical growth, and perfecting cardiovascular and nerve functions. Moreover, thyroid hormone is also an indicator in the thyroid function test, which can directly reflect the functional status of the thyroid gland. During exercise, especially after strenuous exercise, the metabolic level of the body increases, which can also cause the secretion of various hormones in the body to rise, such as thyroid hormone, insulin, growth hormone, adrenocorticotropic hormone and so on, so the thyroid hormone will rise after exercise. If thyroid hormone abnormality occurs, it is recommended to go to the hospital in time.
