Heat Exhaustion

Heat Exhaustion


What Is Heat Exhaustion?

When your body temperature goes up, sweating helps release heat so you can cool down. Heat exhaustion happens when you’re not able to get rid of the extra heat, which can make you sick.

Heat exhaustion comes on suddenly and requires immediate care. The good news is that Aurora Health Care sports medicine experts are frequently on hand to help, since our physical therapists and athletic trainers attend practices and games of sports teams throughout eastern Wisconsin.

Our deep experience in caring for active people also helps us recognize situations that require care in one of our urgent care clinics or emergency rooms. We make recommendations right on the spot so you can get the care you need without delay.

Signs of Heat Exhaustion

Not consuming enough fluids (dehydration) is the primary cause of heat exhaustion. Another factor is the weather: Hot, humid conditions and direct sun exposure make it more difficult for your body to cool itself.

Symptoms of heat exhaustion include:

  • Muscle cramps
  • Dizziness
  • Headache
  • Lightheadedness or fainting
  • Upset stomach
  • Vomiting


Diagnosing Heat Exhaustion

There are no diagnostic tests for heat exhaustion. We diagnose the condition based on your symptoms and the current weather conditions. For instance, if you’ve been exercising in 90-degree heat and high humidity and suddenly feel faint, you likely have heat exhaustion.

To determine whether it is heat exhaustion or something more serious, like heat stroke, we perform a simple physical exam that includes:

  • Feeling your skin: Damp or sweaty skin is a sign of heat exhaustion, while skin that is hot to the touch is a sign of heat stroke.
  • Checking your temperature: A temperature of up to 104°F could be a sign of heat exhaustion. Anything higher could be heat stroke.
  • Asking you about your medical history: We use this information to rule out conditions that may seem similar to heat exhaustion, like low blood sugar (hypoglycemia).


Treating Heat Exhaustion

If you’re experiencing symptoms of heat exhaustion, it's important to get help right away. Often, it’s best to seek immediate care in an urgent care clinic or emergency room, but you can also try simple treatments to bring your temperature down.

Helpful treatments include:

  • Sipping water
  • Sitting or lying down in a shaded or air-conditioned area
  • Taking off unnecessary clothing, including hats and extra shirts
  • Cooling off by taking a cool shower or placing wet towels on your body
