Heat Exhaustion

Over exposure to heat can cause dehydration and exhaustion. It has been extremely warm this summer and heat exhaustion occurs when the body can not cool itself off. Wearing too much clothing in hot weather, exercising or working in the heat without adequate hydration can lead to heat exhaustion.

Some of the signs and symptoms of heat exhaustion includes weakness, nausea and vomiting. Heat exhaustion can lead to a heat stroke if it is untreated.

A heat stroke is a serious insult to the body, resulting in an increase in the body temperature of 104 degrees or higher. Individuals may experience a change of mental status, blood pressure, heart rate, headache, nausea and vomiting. A heat stroke is a MEDICAL EMERGENCY and 911 should be called if anyone is experiencing these symptoms.

Here are suggestions to prevent health exhaustion:

  • Wear lightweight, light-colored, loose-fitting clothing, and a wide-brimmed hat.
  • Use a sunscreen with an SPF of 30 or more.
  • Drink plenty of water to prevent dehydration, especially when working outdoors or exercising.
  • Reduce your intake of alcohol or caffeine during hot weather because both can cause dehydration.

Enjoy the summer and drink more water!
