What is Fever ? Is fever a friend or a foe ?

Fever is caused by rise in body temperature either by a flushed face or by alternative sensation of heat and cold.

It is also marked by rapid pulse, loss of appetite and a feeling of restlessness.

It is generally caused by the invasion of the body by germs. The high temperature is a part of the body defences set up to overcome the disease.

So, fever is a friend as it indicates some disorder in the body requiring treatment.
