An increased body temperature is an important warning sign and should not be ignored.
A high temperature is a reaction to a disease-specific stimulus. This allows the body to support the defence against specific disease mechanisms. Conversely, a change in body temperature can also be caused by other things that are not related to a disease.
The accurate measurement of body temperature is of great medical importance. It allows diseases to be diagnosed early, progress monitored and the effectiveness of prescribed therapies assessed.
