Which process reduces core body temperature during mammalian exercise in a hot environment?

💡 Explanation

Under increased heat load from exercise, cutaneous vasodilation occurs to increase blood flow near skin surface allowing heat loss through radiation because of the greater temperature differential compared to less vasodilation. Therefore peripheral vasodilation reduces core temperature, rather than reduced glycogen usage lowering metabolic demand which would also decrease performance.
