What You Should Know About Heat Exhaustion

Summer brings with it picnics, cookouts by the swimming pool and lazy days soaking up the sun. But when temperatures rise, heat exhaustion is a common illness to keep in mind.

It is important to recognize the signs of heat exhaustion in yourself or others to prevent a serious medical incident. Lia Hanlon, RN, from ER at Damonte Ranch, an extension of Northern Nevada Medical Center, shares some helpful insight.

What are the signs and symptoms of heat exhaustion?

Heat exhaustion occurs when the body becomes overheated, which can result in the body losing too much water and electrolytes. It can happen to anyone who spends time working or exercising outdoors, or is in a hot environment without ventilation or air conditioning.

Symptoms include a fast heart rate, excessive sweating, cool and clammy skin, and fatigue.

Here’s what to do if you or someone you are with experiences these symptoms:

• Seek shade or air conditioning indoors. It is recommended to rehydrate with small sips of water with electrolytes or a sports drink
• Remove any extra layers of clothing
• Fan the body to create airflow
• Wet a cloth with cold water to place on the forehead and back of neck to help cool the body’s core temperature

Do I need to seek emergency care for heat exhaustion?

If you become confused or distressed, lose consciousness or are unable to drink liquids, you should dial 911 immediately to receive medical care.

How can I prevent heat exhaustion?

Whether you are hiking or gardening in your backyard, heat exhaustion can happen at any time, and it is important to properly prepare for outdoor activities. If you are aware of high temperatures, wear loose clothing that will allow airflow and a hat to provide shade, and pack hydrating liquids, including water, sports drinks and electrolytes.

Heat exhaustion is completely preventable. Remain aware of how you are feeling when outdoors to avoid your body temperature from reaching levels at which you will experience symptoms.
