The body thermoregulates during exercise primarily through sweating and blood flow regulation. As core body temperature rises due to muscular exertion, sweat glands produce sweat that evaporates from the skin, cooling the body down. Concurrently, blood vessels near the skin surface dilate, increasing blood flow and allowing heat dissipation. Effective thermoregulation is crucial for maintaining performance and preventing overheating during intense physical activity. Hydration plays a vital role in this process, as fluid loss through sweat can lead to dehydration, impacting both health and athletic efficiency.
