A hiker exerting themselves on a hot day drinks ice water, initially feeling relief. Which consequence follows as their body temperature rises despite the water's cooling effect?

💡 Explanation

As the hiker's body temperature rises, the hypothalamus triggers peripheral vasodilation to dissipate heat, and this overrides the transient cooling from the ice water because the thermoregulatory set point is exceeded; therefore, vasodilation dominates rather than the other options.
