When an animals shiver in the cold muscles move almost uncontrollably. Suggest how shivering helps the animal survive?

Shivering generates heat through the rapid contraction and relaxation of muscles, which helps to raise the animal's body temperature in cold environments. This thermogenic response is crucial for maintaining core body temperature, allowing the animal to sustain vital physiological processes and prevent hypothermia. Additionally, the increased metabolic activity associated with shivering can enhance the animal's energy expenditure, which may be necessary for survival in extreme cold conditions.
