If a desert marathon runner develops anhidrosis (inability to sweat) due to sweat gland fatigue, which consequence follows regarding their core body temperature?

💡 Explanation

Heatstroke becomes likely because the primary thermoregulation mechanism, evaporative cooling via sweat, is impaired. Therefore, core temperature will increase beyond safe limits, risking heatstroke, rather than other compensatory mechanisms being sufficient or the hypothalamus resetting the set point.
