What cause chills durring high fever?
I’vee wondered that myself. A fever is a way your body fights disease. Many microbes that infect us don’t function very well when the temperature goes up. Our own body has a higher tolerance for high temperature then many disease causing microbes. These microbes evolved to be most comfortable at our normal body temperature (98.6). When the temperature goes up bacteria need more iron (which your body hides from bacteria). The high fevers caused by malaria actually kill off syphilis. (This was used as a treatment for a little while before they came up with penicillin, which most people prefer to malaria). Also, heat speeds up some biological processes, and our immune system likes temperatures a bit higher then the rest of the body prefers. When you have a fever your body cranks up the thermostat in the hypothalamus. The body’s thermostat launches various temperature-raising procedures any time your body goes below whatever temperature it is set at. It shifts blood away from your skin, to
