Answer:
When the body temperature rises because of an infection, it's called fever. Fevers are caused by chemicals in the bloodstream called pyrogens. Pyrogens make their way to the brain's hypothalamus, which is in charge of regulating body temperature.Doctors think one reason for a fever is to raise the body's temperature enough to kill off bacteria and viruses that are sensitive to temperature changes. In debate right now is whether we should be trying to lower fevers. Aspirin, for example, will reduce fever. Still, if the fever is helping rid the body of infection, then lowering it could be counterproductive. On the other hand, people sometimes die from fever. The general medical consensus right now leans to the "reduce the fever" side of the fence.
