Centers for Disease Control and Prevention. Lightweight, loose-fitting clothing helps sweat evaporate and keeps you cooler. Metabolic rate - Rate of energy (heat) production of the body which varies with the level of activity. Hypothermia Hypothermia is a dangerous drop in body temperature below 35C (normal body temperature is around 37C). The heart rate increases to pump more blood through outer body parts and skin so that excess heat is lost to the environment, and sweating occurs.
