Understanding Heat-Related Illnesses

Heat-related illnesses occur when the body is unable to cool itself effectively. Normally, sweating helps regulate body temperature, but prolonged heat exposure, dehydration, and strenuous physical activity can overwhelm the body’s cooling system.

Heat exhaustion and heat stroke exist on the same spectrum of heat illness. Heat exhaustion is a serious condition that requires immediate attention, while heat stroke is a medical emergency that can result in organ damage or death if not treated promptly.

According to the CDC, heat-related illnesses become more common during periods of high heat and humidity, particularly among individuals who spend significant time outdoors.

What Does Heat Exhaustion Feel Like?

Heat exhaustion typically develops after prolonged exposure to hot conditions, especially when combined with physical activity. The body loses large amounts of fluids and electrolytes through sweating, leading to dehydration and reduced circulation.

Common symptoms of heat exhaustion include:

• Excessive sweating
• Weakness or fatigue
• Dizziness
• Headache
• Muscle cramps
• Nausea
• Vomiting
• Pale or clammy skin
• Rapid heartbeat

Many people describe feeling drained, lightheaded, or unusually weak. Symptoms often improve with rest, hydration, and moving to a cooler environment.

When Heat Exhaustion Becomes Heat Stroke

Heat stroke occurs when the body’s temperature rises to dangerous levels and the cooling system begins to fail. Unlike heat exhaustion, heat stroke affects the brain and central nervous system.

Warning signs of heat stroke include:

• Body temperature above 104°F
• Confusion or disorientation
• Slurred speech
• Hot skin
• Loss of consciousness
• Seizures
• Rapid pulse
• Difficulty responding to questions

If someone develops these symptoms, call 911 immediately. Heat stroke is not something that can be treated at home.

The Mayo Clinic identifies confusion and altered mental status as some of the most important warning signs that heat exhaustion may have progressed into heat stroke.

Comparing Heat Exhaustion and Heat Stroke

Because both conditions result from overheating, they share several symptoms. However, there are important differences that can help determine the severity of the situation.

With heat exhaustion, a person is usually still alert and sweating heavily. Their skin may feel cool, damp, or clammy despite the hot weather. They may complain of fatigue, headaches, or dizziness but can typically communicate normally.

With heat stroke, the situation becomes far more dangerous. Mental confusion, loss of consciousness, seizures, or a very high body temperature indicate a medical emergency. The body’s temperature regulation system is no longer functioning properly and immediate intervention is necessary.

Who Faces the Highest Risk?

Anyone can develop heat exhaustion or heat stroke, but some groups are especially vulnerable.

Individuals at increased risk include:

• Young children
• Older adults
• Outdoor workers
• Athletes
• People with heart disease
• Individuals with diabetes
• Those taking medications that affect hydration
• People who are not acclimated to hot weather

In Hickory, outdoor recreation, sporting events, festivals, and physically demanding jobs can increase the likelihood of heat-related illness during the summer months.

How to Prevent Heat Illness

Fortunately, many heat-related illnesses can be prevented with proper precautions. Paying attention to hydration and limiting heat exposure can significantly reduce your risk.

Helpful prevention tips include:

• Drink water consistently throughout the day
• Wear lightweight clothing
• Take breaks in shaded or air-conditioned areas
• Avoid strenuous activity during peak afternoon heat
• Use sunscreen to reduce additional stress on the body
• Replace electrolytes during prolonged outdoor activity
• Monitor children and older adults closely

The National Weather Service recommends planning outdoor activities during cooler parts of the day whenever possible.
