Detailed explanation-1: -When the air is super cold, it will take away your body heat, leaving you feeling – you guessed it – cold! As part of the process of homeostasis, shivering is one way that your body tries to produce more warmth and make up for all the heat it’s losing to the cold air.

Detailed explanation-2: -A shiver is caused by your muscles tightening and relaxing in rapid succession. This involuntary muscle movement is your body’s natural response to getting colder and trying to warm up.

Detailed explanation-3: -Rigors are episodes in which your temperature rises-often quite quickly-whilst you have severe shivering accompanied by a feeling of coldness (’the chills’). The fever may be quite high and the shivering may be quite dramatic.

Detailed explanation-4: -Shivering is an involuntary somatic motor response that occurs in skeletal muscles to produce heat during exposure to cold environments or during the development of fever.
