Emergency: Heat Exhaustion

Heat exhaustion occurs when the body is unable to cool itself adequately. Usually this results from exercising in a hot, humid environment and is often brought on by dehydration.

Caution should be taken when trying to nourish dehydration. It should not be done quickly.

Symptoms include:

• Heavy sweating;
• Pale, cool, clammy skin;
• Muscle cramps/spasms;
• Dizziness or drowsiness
• Nausea or vomiting;
• Headache;
• Elevated pulse; and
• Elevated core body temperature (above 37 degrees Celsius).

If you suspect someone is suffering from heat exhaustion:

• Rehydrate the person with cool water, milk, soup or sports drinks. Caution should be taken if they are
  diabetic;
• Ensure they are in a cool area out of direct sunlight;
• Loosen or remove clothing;
• Apply a cool compress to skin;
• Avoid giving alcohol or caffeinated beverages; and
• Seek medical advice by using a VHF marine radio or cell phone.
