Heatstroke and heat exhaustion are the most serious of the heat-related illnesses. Heat exhaustion occurs from exposure to a very hot, humid environment when excessive sweating can lead to dehydration. Heatstroke results from prolonged heat exposure, dehydration from sweating, and failure of the brain's temperature control mechanism. With heatstroke, body temperature exceeds 105 degrees and can cause brain and organ damage, and even death. Elderly people are most often affected, and increased risks are associated with working in a very hot environment, alcohol or drug abuse, chronic illness, recent illnesses with fluid loss (vomiting or diarrhea), hot and humid weather, lack of fluid replacement, heavy restrictive clothing, and severe fever.  

Symptoms may include:

Heat exhaustion:

• Dizziness
• Fatigue or weakness
• Headache
• Feeling faint
• Pale, clammy skin
• Rapid heart rate
• Rapid, shallow breathing
• Muscle cramps
• Profuse sweating
• Intense thirst

Heatstroke:

• Hot, dry, and flushed skin without sweating
• Elevated body temperature (>105 F)
• Rapid heartbeat
• Confusion or disorientation
• Loss of consciousness

WHAT YOUR DOCTOR CAN DO:

WHAT YOU CAN DO:

• Quickly cool the heatstroke victim by immersing in cool water. If possible, use wet sheets to wrap and apply ice packs.
• A person who faints, but is sweating, should be placed in a prone position (lying down on the stomach) on a cool surface (preferably shaded), given cool (not cold) liquids such as water, juice, or a soft drink; and taken to the hospital.
Prevent heatstroke and heat exhaustion:
• Wearing light, loose-fitting clothing in hot weather and drinking fluids frequently.
• Drinking extra water if you are sweating heavily or urinating less.
• Improving ventilation if feeling overheated by opening a window, using a fan, or using an air conditioner.

WHAT YOU CAN EXPECT:

CALL 1061 OR SEEK IMMEDIATE MEDICAL ASSISTANCE If you suffer symptoms of heat exhaustion or heat stroke! Emergency treatment is necessary.
