Summer Heat Is Here – What Is Heat Stroke?

As temperatures rise across Texas, spending time outdoors becomes a favorite summer activity. Whether you're attending sporting events, working in the yard, exercising, or simply enjoying time with family, it's important to understand the dangers of extreme heat. One of the most serious heat-related illnesses is heat stroke.

What Is Heat Stroke?

Heat stroke is a medical emergency that occurs when the body's temperature rises to 104°F (40°C) or higher and can no longer cool itself effectively. Unlike heat exhaustion, which is less severe, heat stroke can cause damage to the brain, heart, kidneys, and muscles if not treated immediately.

Common Signs and Symptoms

Symptoms of heat stroke may include:

• High body temperature
• Confusion or altered mental status
• Slurred speech
• Dizziness
• Headache
• Rapid heartbeat
• Nausea or vomiting
• Hot, dry skin or excessive sweating
• Loss of consciousness

If someone is experiencing these symptoms, call 911 immediately.

Who Is Most at Risk?

Anyone can develop heat stroke, but certain groups face a higher risk:

• Adults over age 65
• Infants and young children
• People with chronic medical conditions
• Outdoor workers
• Athletes
• Individuals taking certain medications that affect hydration

How to Prevent Heat Stroke

Fortunately, heat stroke is often preventable. Consider these safety tips:

• Drink water regularly throughout the day.
• Avoid strenuous outdoor activities during peak afternoon heat.
• Wear lightweight, light-colored clothing.
• Take frequent breaks in shaded or air-conditioned areas.
• Never leave children or pets in parked vehicles.
• Use sunscreen to prevent sunburn, which can impair the body's ability to cool itself.

When to Seek Medical Attention

If you experience symptoms of heat exhaustion—such as heavy sweating, weakness, dizziness, or muscle cramps—move to a cooler location and hydrate immediately. If symptoms worsen or mental confusion develops, seek emergency medical care right away.
