Having a skin that is pale, cold, and clammy are symptoms of heat exhaustion. Also, when your pulse is rapid, breathing is shallow are symptoms of such. One main cause of this would be being exposed to high temperatures especially when humidity is high and one is doing a physical activity. When no proper treatment, it could lead to heatstroke which may eventually cause death of the person. When one suspects that he is experiencing this, he should stop all that he is doing and rest. Then, he should move to place which has a cooler temperature. And drink fluids that are cold specifically water and sport drinks.
