What is the Immediate Response of the body To Cold Stimulus?

The immediate response of the body to a cold stimulus involves several physiological changes aimed at preserving core temperature. Blood vessels constrict (vasoconstriction) to reduce blood flow to the skin, minimizing heat loss. Additionally, shivering may occur as muscles contract involuntarily to generate heat. The body also releases hormones like adrenaline to boost metabolism and further increase heat production.
