why do our temperature rise when we have a fever?

Answer 1

The body's way of trying to kill the infection cause by bacteria or a virus.

Answer 2

In the brain, the hypothalamus has a thermal set point to regulate our bodies' temperature. During an infection there is a complicated chain reaction of chemicals that eventually raise the level of prostaglandins which act on the hypothalmus, raising that thermal set point higher (aspirin is a prostaglandin inhibitor, which is why it lowers a fever) Once this thermal set point has been elevated, the thermoregulatory mechanisms throughout the body act to raise the body temperature to the level of the new set point; The autonomic nervous system causes heat conversion through vessel constriction and cessation of sweating. Special nerves increase heat production by increasing skeletal muscle tone or shivering. This may cause the muscle aches that some people get when they have a fever.

Answer 3

Fever is the results from an imbalance between the elimination and the production of heat. Exercise, anxiety, an dehydration can all contribute to fever in healthy people. It is usually a sign of an infection and is the body's way of saying get it checked out. No single therapy explains the mechanism whereby the temperature is increased. Very high temperatures can be fatal if not treated.
