Why 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.
