Heat exhaustion can happen to anyone in the triple-digit temperatures that we have in the Phoenix desert. Here is how you recognize heat exhaustion and how to handle it.

Difficulty: Average

Time Required: A few minutes

Here's How

  1. If a person has heat exhaustion, he/she may be weak or tired.
  2. A person experiencing heat exhaustion, he/she could pass out and collapse.
  3. A person with heat exhaustion may appear pale.
  4. Heat exhaustion may give a person clammy skin.
  5. If a person has heat exhaustion, he/she could be sweating profusely.

  1. Fan the person or apply cool water to the person's body to lower the temperature.
  2. Give the person electrolyte beverages, like Gatorade, or small sips of salt water.
