Stay Safe This Summer By Knowing The Signs of Heat Exhaustion

As temperatures spike, spending extended time outdoors can greatly increase the risk of heat-related illnesses. Heat exhaustion is the most common form of heat sickness, and even though it is common, it shouldn’t be mistaken as harmless. This condition can rapidly become dangerous if left untreated. 

It is important that all residents of North Jefferson County Ambulance District understand and recognize the signs of heat exhaustion, know how to treat it, and recognize the warning signs of when it may be progressing to heat stroke. This knowledge will help keep you, your family, friends, and neighbors safe so you can enjoy the summer heat without worrying.

What Is Heat Exhaustion?

Heat exhaustion is a condition that occurs when the body is subjected to prolonged exposure to high heat, resulting in it overheating and struggling to regulate its temperature. This condition becomes especially prevalent if the affected person is dehydrated or participating in any form of strenuous activity, such as yard work, sports, etc.

Heat exhaustion is a heat-related illness that calls for immediate attention but is normally less severe than heat stroke.

Heat Exhaustion vs Heat Stroke

Many people use these terms interchangeably, but there are key differences between heat exhaustion and heat stroke, such as:

• Heat exhaustion is an early form of heat sickness. The body is overheated, but it can still regulate its own temperature to a certain extent. 

• Heat stroke is a medical emergency that results from the body’s natural temperature regulation mechanisms failing entirely. This results in the body heating rapidly to what can become lethal temperatures.

Without prompt treatment, heat exhaustion can progress into heat stroke and can even become fatal. 

How long does heat exhaustion last?

The duration of heat exhaustion is dependent on numerous factors, including:

• The severity of the symptoms 

• How promptly treatment is provided

• The affected individual’s overall health and constitution

Most affected individuals begin to feel improved within 30 minutes to a few hours after moving to a cooler environment, replenishing their fluid intake, and resting. However, there are also individuals who continue to feel fatigued and sensitive to heat for up to 48 hours following treatment. 

We strongly advise that if the symptoms persist or worsen after treatment, call 911 right away. 

Symptoms of heat exhaustion

Recognizing the symptoms of heat exhaustion early could prevent a fun day out in the sun from ending in the emergency room. Common signs of heat exhaustion to keep an eye out for include:

• Heavy sweating

• Cool, pale, or clammy skin

• Excessive thirst

• Dizziness or lightheadedness

• Headache

• Muscle cramps

• Weakness or fatigue

• Nausea or vomiting

• Rapid heartbeat

• Fainting

If you or someone around you is experiencing these symptoms, promptly move to a cooler location and begin treatment right away. It is also crucial that whoever is performing the treatment watches that the symptoms do not progress into heat stroke.

• A body temperature of 103°F or higher

If you suspect someone is experiencing heat stroke, call 911 immediately while taking steps to cool the person down.

How To Treat Heat Exhaustion

To effectively and safely treat heat exhaustion, follow these steps:

1. Move to a cool, shaded, or air-conditioned area.

2. Stop all physical activity and rest.

3. Drink cool water or a sports drink containing electrolytes.

4. Loosen or remove excess clothing.

5. Apply a cool, wet cloth to the skin.

6. Take a cool shower or bath if possible.
