Heat-related illnesses consist of three stages, ranging from relatively mild to life threatening: heat cramps, heat exhaustion and heatstroke, respectively. Recognize and treat symptoms as soon as possible, especially before earlier stages progress to heatstroke. These guidelines follow recommendations of the American Red Cross and the Center for Disease Control.
