The primary risk associated with prolonged high temperatures for athletes is dehydration. When athletes exercise in hot conditions, their bodies lose water and essential electrolytes through sweat. If fluid intake does not keep pace with fluid loss, dehydration can occur, which can impair performance and lead to serious health complications.

Dehydration affects physical and cognitive functions, resulting in decreased endurance, increased fatigue, and a heightened risk of heat-related illnesses. It is crucial for athletes to recognize the signs of dehydration, such as thirst, dry mouth, fatigue, and dark urination, and to implement proper hydration strategies before, during, and after physical activity in hot weather.

Other factors, like heat exhaustion and sickle cell crisis, while related to heat, are more specific conditions that can arise from, or be exacerbated by dehydration and other pre-existing health conditions. Similarly, while competitive disadvantages may occur due to heat, they stem from the physiological impairments caused by dehydration and other heat-related illnesses, making dehydration the most critical and immediate risk.
