Our body has lots of ways to fight off the germs that make us sick. One of those ways is to crank up our internal temperature to make it too hot for harmful bacteria to survive. This is called a fever. How do our bodies reach those hot fever temperatures? We asked physician Dr. Joe Alcock to help us find the answer. Got a burning question? Send it to us at BrainsOn.org/contact, and we’ll help find an answer that’s a real fever reliever!
