Warning signs of heat stroke, exhaustion

TINKER AIR FORCE BASE, Okla. -- Heat Stroke

Heat stroke is the most serious and life-threatening heat-related illness. In certain circumstances, your body can build up too much heat, your temperature may rise to life-threatening levels, and you can become delirious or lose consciousness. If you do not rid your body of excess heat fast enough, it "cooks" the brain and other vital organs. It is often fatal, and those who do survive may have permanent damage to their vital organs.

Symptoms of heat stroke include:
· The victim's body feels extremely hot when touched.
· Altered mental status (behavior) ranging from slight confusion and disorientation to coma.
· Conscious victims usually become irrational, agitated or even aggressive and may have seizures.
What to do:
· Move person to a half-sitting position in the shade.
· Call for emergency medical help immediately.
· If humidity is below 75 percent, spray victim with water and vigorously fan. If humidity above 75 percent, apply ice packs on neck, armpits or groin.
