The thyroid gland secretes hormones that influence metabolism, body temperature, growth, and brain development. Hyperthyroidism occurs when too much thyroid hormone is secreted, leading to increased heart rate and appetite with potential heart problems. Hypothyroidism is caused by not enough thyroid hormone, resulting in tiredness, weight gain, and raised cholesterol. Exercise can help control thyroid hormone levels and decrease health risks like cardiovascular disease and joint pain.
