Shivering

You'll find yourself vacillating between temperature extremes when you have multiple ailments. You may feel cold one moment and hot the next. And while a fever has its own function, which we'll discuss in a moment, what function does feeling chilly and shivering serve?

Shivering is essentially stage one of a two stage process that occurs when you are ill and chilly. Fever is frequently brought on by the second portion, but they must go together. In order to fight against illness, your body wants to heat up, but it can't just do that. Shivering is used to create heat since you must find a way to do it.

Your muscles start rapidly contracting and relaxing. The physical action causes heat. When your body temperature rises high enough, the shaking stops, and a fever develops.
