Heat Exhaustion First Aid

heat exhaustion

When temperatures rise so does the risk of heat exhaustion and heatstroke. Being outdoors in hot humid weather can quickly lead to dehydration.

Symptoms

Early signs:

  • Excessive sweating
  • Fatigue
  • Thirst
  • Muscle cramps
  • Headache

Later more serious signs may occur:

  • Lightheadedness
  • Weakness
  • Nausea and Vomiting
  • Cool, moist skin
  • Dark urine

First Aid Treatment for Heat Exhaustion and Heat Stroke are much the same and is as follows:

  • If a person has a temperature of 40°C (104°F) or displays any of the symptoms of heatstroke seek medical help immediately
  • Remove the person from the heat
  • Remove clothing and have the person lie down
  • Elevate the feet slightly about 30 cm (12 inches)
  • Place a cold compress on the head, neck, groin and under the armpits
  • Use fans to cool down the body
  • If the person affected is awake you can place them in a cool bath or if outside spray gently with a garden hose
  • If the person is awake encourage them to sip a salt beverage. Gatorade, or similar, or a teaspoon of salt in a 4 cups/a quart of water. Drink half a cup every 15 minutes. Cool water is also acceptable
  • If muscle cramping is a problem massage the cramp gently until the muscle relaxes. Muscle cramps are extremely painful so be guided by the person as to how hard or gentle to be.
  • Watch for signs of shock (bluish lips and fingernails, loss of alertness) call your local emergency services immediately

Some DO NOT's:

  • DO NOT underestimate the seriousness of heat exhaustion and heat stroke especially in children.
  • DO NOT give a child or person aspirin or pain killers. These will not help.
  • DO NOT give salt tablets.
  • DO NOT give any liquids that contain alcohol or caffeine. These are diuretics and will hinder the body's ability to re-hydrate.
  • DO NOT use alcohol rubs on the body.
  • DO NOT give an affected person any liquids (including salt drinks) if the person is vomiting or losing consciousness.
