Heat Exhaustion & Heatstroke

Signs and Symptoms:
Heat Exhaustion:

  • Severe thirst
  • Muscle weakness
  • Nausea, sometimes vomiting
  • Fast, shallow breathing
  • Irritability
  • Headache
  • Increased sweating
  • Cool, clammy skin
  • Elevation of body temperature to 105 degrees Fahrenheit (40.6 degrees Celsius)

Heatstroke:

  • Severe, throbbing headache
  • Weakness, dizziness, or confusion
  • Difficulty breathing
  • Decreased responsiveness or loss of consciousness
  • Little or no sweating
  • Flushed, hot, dry skin
  • Elevation of body temperature to 105 degrees Fahrenheit (40.6 degrees Celsius) or higher

What to Do:
If you show signs or symptoms of heatstroke, seek emergency medical care immediately.  In cases of heat exhaustion and while awaiting help with possible heatstroke:

  • Go indoors or into the shade immediately.
  • Get undressed
  • Lie down; elevate feet slightly.
  • Take a cool (not cold) bath, or sponge bathe repeatedly.  If outside, cool down using a garden hose.
  • Take frequent sips of cool, clear fluids (clear juices or sports drinks are best).
  • If vomiting, turn body to the side to prevent choking.
  • Monitor your temperature.

Think Prevention!
Always drink plenty of fluids before and during any activity in hot, sunny, weather – even if you aren't thirsty.  Wear light-colored loose clothing and only participate in heavy activity outdoors before noon or after 6 PM.  Go indoors immediately whenever feeling overheated.
