← Human Body & HealthWhy does fever in humans trigger shivering despite elevated body temperature?
A)Increased thyroid hormone production increases heat
B)Metabolic rate decreases to conserve energy
C)Hypothalamus raises body temperature set point✓
D)Peripheral vasodilation causes heat loss
💡 Explanation
Fever induces shivering because the hypothalamus elevates the body's thermoregulatory set point, which triggers cold-response mechanisms to reach the new target. Therefore, shivering generates heat to match the higher set point, rather than directly responding to the actual body temperature.
