During exercise, the body adapts to heat through several physiological mechanisms, such as increased sweating and enhanced blood flow to the skin. As one’s body temperature rises, the hypothalamus triggers sweat production, which cools the body through evaporation. This adaptation process helps maintain exercise performance and prevent overheating. Over time, consistent exposure to heat can lead to improved efficiency in sweat production and alterations in heart rate and blood plasma volume. These adaptations enhance overall endurance, enabling individuals to perform better in various conditions while reducing heat-related risks.
