Cold and the Body

Keywords: temperature extremes, wind chill, hypothalamus, heat loss, conduction, convection, radiation, evaporation, automatic temperature regulation, shivering, metabolism, vasoconstriction, risk factors.

Abstract: Humans are well equipped to lose heat, but are less efficient in retaining it. A small drop in body temperature brings the temperature regulation mechanisms into action: blood vessels in the skin constrict to prevent excessive heat loss and muscles shiver to create heat. The mechanisms are designed to protect the core. But if the system fails or becomes overwhelmed, cold-related illness or death is the consequence. Every person reacts differently to thermal stress. Age, fitness level and underlying diseases play a major part in someone’s reaction to cold.
