"The Germ-Killing Power of Fevers Explained"

Fevers help the body fight infections by spurring various immune processes. Elevated body temperatures trigger the immune system to fight infections by enhancing immune function and stimulating both the innate and adaptive compartments of the immune system. Fevers also recruit first-responder immune cells, boost dendritic cells' ability to engulf harmful microbes, and may hamper a pathogen's chances of winning the battle. Studies show that intensive-care patients are more likely to recover from an infection if they develop a fever, indicating the beneficial effects of fever in fighting infections.
