Why does administering antipyretics reduce fever, but not during exercise-induced hyperthermia?

💡 Explanation

Antipyretics reduce fever because they inhibit prostaglandin synthesis, which resets the hypothalamic set point for body temperature to a lower value. Therefore, the body reduces heat production and increases heat loss to match the new set point. Rather than acting directly on thermoregulation, exercise-induced hyperthermia overwhelms the body's cooling mechanisms.
