Q1. An athlete with a history of heat exhaustion is advised to avoid exercising in hot, humid conditions. Which physiological mechanism contributes to this condition?
Answer: Disrupted sweating response fails to regulate body temperature
Explanation: Impaired thermoregulation due to disrupted sweating response leads to heat exhaustion. Incorrect options: excessive sweating is a symptom, not a cause; poor blood circulation hampers heat loss, but is not the primary cause of heat exhaustion; increased cardiac output enhances heat dissipation, but is not directly related to heat exhaustion.
