Extreme Heat

  • Heat cramps – Muscle pains or spasms due to heavy exertion. Although heat cramps are the least severe, they are usually the first signal that the body is having trouble with heat.
  • Heat exhaustion – Occurs when people exercise or work in a hot, humid place where body fluids are lost via heavy sweating. Blood flow to the skin increases, causing blood flow to decrease to vital organs, which can result in a form of mild shock. If left untreated the victim’s body temperature will keep rising and he may suffer heat stroke.
  • Heat stroke (sun stroke) – Occurs when the victim’s temperature control system, which produces sweat, stops working. The body temperature can rise high enough to cause brain damage or death, if the body is not cooled quickly.
  • If possible, avoid strenuous outdoor activities
  • Stay indoors and limit exposure to the sun
  • If outside, apply sunscreen uniformly to cover all exposed areas for 15 minutes before exposure

  • Dress in loose-fitting, lightweight, and light-colored clothes that cover as much of your body as possible
