When the body's phagocytes release pyrogens, the hypothalamus responds by resetting the body's thermostat to a higher temperature. This increase in temperature triggers shivering in the person, which generates heat and helps to raise the body's temperature to the new set point. This process is known as fever, and it is an important defense mechanism the body uses to fight infections.
