Heat stress occurs when the body is unable to cool itself through sweating, causing the core body temperature to rise dangerously. Symptoms range from mild heat rash and cramps to severe heat exhaustion and heat stroke, which is life-threatening. To prevent heat stress, it is important to drink plenty of water even if not thirsty, take regular breaks in cool areas, and wear loose, light clothing. If someone shows signs of heat illness, call for help, move them to a shaded cool area, cool their body with water, and call 911 immediately if experiencing heat stroke.
