Detailed explanation-1: -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-2: -A Thing Called Homeostasis 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-3: -When the core body temperature drops, the shivering reflex is triggered to maintain homeostasis. Skeletal muscles begin to shake in small movements, creating warmth by expending energy. Shivering can also be a response to fever, as a person may feel cold.
