Why do we get fevers when sick?
Show answer & explanation
Answer: Heat helps fight infection
Germs make us hot — Wrong. Germs don't directly produce the heat. Your immune system deliberately raises body temperature.
Body loses temperature control — Wrong. Fever is controlled, not accidental. Your body intentionally raises its thermostat setting.
Heat helps fight infection ✓ — Correct! Your brain raises body temperature on purpose! Higher temperatures help immune cells work faster and make it harder for some germs to survive. Fever is actually your body's defense mechanism!
