Treatments and drugs

By Mayo Clinic staff

In most cases, you can treat heat exhaustion yourself by doing the following:

  • Rest in a cool place. Getting into an air-conditioned building is best, but at the least, find a shady spot. Rest on your back with your legs elevated higher than your heart level.
  • Drink cool fluids. Stick to water or sports drinks. Don't drink any beverages that have alcohol or caffeine, either of which can contribute to fluid loss.
  • Apply cool water to your skin. If possible, take a cool shower or soak in a cool bath. Don't use alcohol on your skin.
  • Loosen clothing. Remove any unnecessary clothing and make sure your clothes are lightweight and nonbinding.

If you don't begin to feel better within 60 minutes of using these treatment measures, seek prompt medical attention. You may be given intravenous (IV) fluids to help you rehydrate. Immersion in cold water, misting your skin, placing you in front of fans, or using cold or ice packs and cooling blankets are some of the techniques that may be used to bring down your body temperature.
