Question

what happens when you get fever?​

Answer 1

Fever is caused by chemicals known as pyrogens, flowing in the bloodstream. ... Our body's temperature rises when the pyrogens reach the brain and bind to certain receptors in the hypothalamus.When you have an infection, you make lots of these cells. ... The increase in these white blood cells affects your hypothalamus. This makes your body heat up, causing a fever. In the early stages of a fever, you often feel cold and start to shiver.
