Fevers - Causes, Symptoms, Treatment, Immediate medical help

Our body keeps adapting to several changes in the external environment.

While fighting back various chemicals are released and the temperature of our body rises. This, in simple terms is commonly known to us as fever. 

The normal body temperature may range anywhere from 97 degree Celsius to 99 degree Celsius. If the temperature rises beyond that, it is considered a fever. As fever is a body’s natural response to infection, a low-grade fever isn’t usually a cause for concern, but if it is longstanding or temperature of 102°F and above should be treated.
