During intense exercise, if cutaneous vasodilation alone proves insufficient to maintain thermoregulation, which compensatory mechanism is triggered to further lower core body temperature?

💡 Explanation

Eccrine sweat gland activation becomes essential because evaporative cooling provides a significant avenue for heat dissipation when vasodilation is inadequate. Therefore, sweat glands activate rather than hormonal changes or shivering suppression, because those mechanisms regulate long-term temperature adjustments, not immediate heat loss during exercise.
