Thermal regulation during exercise is essential for maintaining core body temperature. As the body generates heat through physical activity, effective heat dissipation mechanisms—such as sweating and increased blood flow to the skin—are crucial for preventing overheating. Impaired thermal regulation can lead to heat-related illnesses, such as heat exhaustion or heat stroke, compromising athletic performance. Proper hydration and acclimatization to environmental conditions also play a critical role in facilitating thermal regulation, ensuring that athletes can perform safely and effectively.
