Learn how to spot the warning signs of heat exhaustion and heat stroke and when to visit AFC Sevierville for treatment.
From hiking scenic trails in the Great Smoky Mountains National Park to spending a sunny afternoon at Sevierville City Park, summer in Sevierville encourages residents and visitors alike to spend more time outdoors. While enjoying East Tennessee’s natural beauty, it’s important to remember that prolonged exposure to high temperatures can put serious stress on the body. Heat exhaustion and heat stroke are two of the most common heat-related illnesses, but they require very different responses. Understanding how these conditions develop and recognizing their symptoms early can help you stay safe during the hottest days of the year.

Why Heat-Related Illnesses Happen
Your body is constantly working to maintain a safe internal temperature. When temperatures rise, sweating helps cool the body down. However, excessive heat, humidity, physical activity, and dehydration can overwhelm this natural cooling process.
When this happens, heat-related illnesses can develop quickly. Heat exhaustion is often the body’s first warning sign that it is struggling to regulate temperature. If ignored, it can progress into heat stroke, a dangerous condition that requires immediate emergency medical care.
According to the CDC, heat-related illnesses become more likely during periods of high temperatures, especially when people spend extended time outdoors.
Understanding Heat Exhaustion
Heat exhaustion occurs when the body loses significant amounts of water and electrolytes through sweating. Without enough fluids, the body begins to struggle with circulation and temperature regulation.
Common symptoms of heat exhaustion include:
- Heavy sweating
- Dizziness
- Headache
- Fatigue
- Muscle cramps
- Nausea
- Vomiting
- Weakness
- Cool, moist skin
Many people with heat exhaustion feel drained and unable to continue normal activities. Fortunately, symptoms often improve when the person moves to a cooler environment, rests, and rehydrates.
Recognizing the Signs of Heat Stroke
Heat stroke is far more serious than heat exhaustion. It develops when the body can no longer cool itself effectively and internal temperatures rise rapidly.
Warning signs of heat stroke include:
- Body temperature of 104°F or higher
- Confusion
- Disorientation
- Slurred speech
- Rapid heartbeat
- Seizures
- Loss of consciousness
- Hot skin
Unlike heat exhaustion, heat stroke can cause damage to vital organs and become life-threatening within a short period of time.
The Mayo Clinic identifies confusion and changes in mental status as some of the clearest indicators that heat stroke may be occurring.
Heat Exhaustion vs. Heat Stroke: Key Differences
Although these conditions share similarities, understanding the differences can help determine the appropriate response.
With heat exhaustion, a person is usually still sweating heavily and remains alert, although they may feel weak or dizzy. Their skin often feels cool, clammy, or damp.
Heat stroke is characterized by neurological symptoms such as confusion, loss of consciousness, seizures, or difficulty communicating. Body temperature is significantly elevated, and the person’s condition can deteriorate rapidly without emergency treatment.
When in doubt, it is always safest to seek medical evaluation.
Who Is Most Vulnerable?
While anyone can experience heat-related illness, certain groups face a higher risk.
People most vulnerable include:
- Young children
- Adults over age 65
- Athletes
- Outdoor workers
- Individuals with heart disease
- People with diabetes
- Those taking medications that affect hydration
- Individuals who are not acclimated to hot weather
In Sevier County, outdoor recreation, tourism activities, sporting events, and physically demanding jobs can increase exposure to extreme heat during the summer months.

Fortunately, there are several ways to lower your risk of heat exhaustion and heat stroke.

- Wear lightweight, breathable clothing
- Take breaks in shaded or air-conditioned areas
