Detailed explanation-1: -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.

Detailed explanation-2: -Shivering increases muscle cell activity, which in turn produces heat. Severe shivering is one of the signs of hypothermia.

Detailed explanation-3: -Your muscles begin to quickly tighten and loosen over and over again in a short period, which is what we call shivering. The energy that’s created to make your muscles produce shivers gives off heat, helping to keep you a bit warmer!

Detailed explanation-4: -Shivering-nerve impulses are sent by the hypothalamus to the skeletal muscles to bring about rapid contractions that generate heat. Shivering therefore helps raise the body temperature. Increase in metabolic rate-the liver produces extra heat in order to raise the temperature of the body.

Detailed explanation-5: -Shivering is part of the body’s natural response to an illness. When a person shivers, it helps their body temperature rise, which helps fight off a virus or a bacterial infection.
