← Human Body & HealthIf a person exercising intensely on a hot, humid day stops abruptly, which consequence related to thermoregulation follows?
A)Immediate cessation of vasodilation occurs
B)Sweat evaporation decreases; core temperature rises✓
C)Shivering begins to generate heat
D)Hypothalamus set point decreases rapidly
💡 Explanation
When exercise stops abruptly in humid conditions, the sweat rate is sustained briefly, but evaporation diminishes because of increased environmental humidity; therefore, heat dissipation decreases, raising core temperature, rather than initiating shivering or instantaneously altering hypothalamic set points. Vasodilation remains active temporarily, rather than ceasing immediately.
