First Aid: Your Guide to Understanding and Preventing Heat Stroke

Summer brings sunshine, adventures, and quality time with family and friends. But as temperatures climb, it’s important to stay aware of heat-related health risks that can turn a perfect day into a medical emergency. Heat stroke is one of the most serious heat-related conditions, but with the right knowledge and preparation, it’s entirely preventable.

Whether you’re planning a family beach day, attending outdoor events, or simply spending time in your backyard, understanding heat stroke can help you keep yourself and your loved ones safe all season long.

What is Heat Stroke?

Heat stroke is a serious condition that occurs when your body overheats, typically as a result of prolonged exposure to high temperatures or physical exertion in hot weather. It’s most common during the summer months, especially in hot, humid environments. When the body’s core temperature reaches 104°F (40°C) or higher, it can lead to life-threatening complications without prompt treatment.

Common Causes of Heat Stroke

Heat stroke is usually the result of specific conditions and circumstances that overwhelm your body’s natural cooling system. Being aware of these common triggers can help you avoid dangerous situations:

• Hot environments: Extended time in high temperatures, particularly without adequate ventilation or cooling, raises core body temperature.
• Strenuous activity: Physical exertion in the heat, especially for those unacclimated to the climate, can increase the risk.
• Excessive clothing: Wearing heavy or tight clothing prevents sweat from evaporating, interfering with the body’s cooling process.
• Alcohol consumption: Alcohol can impair your body’s ability to regulate temperature.
• Dehydration: Failing to drink enough fluids can hinder your body’s ability to sweat and cool itself properly.

Symptoms of Heat Stroke

Unlike heat exhaustion, heat stroke symptoms are severe and require immediate medical attention. Watch for these critical indicators:

• High body temperature (104°F or above)
• Confusion, agitation, or altered mental state
• Decreased or absent sweating despite the heat
• Nausea and vomiting
• Red, hot skin
• Rapid, shallow breathing
• Elevated heart rate
• Throbbing headaches

Tips for Preventing Heat Stroke

The good news is that heat stroke is completely preventable with smart planning and simple precautions. These practical strategies can help you enjoy the outdoors safely, even on the hottest days:

• Wear lightweight, loose-fitting clothing that allows heat to escape.
• Apply a broad-spectrum sunscreen (SPF 15 or higher) to prevent sunburn, which can limit your body’s ability to cool down.
• Stay hydrated—drink plenty of water throughout the day.
• Avoid outdoor activity during the hottest parts of the day, and rest in shaded or air-conditioned areas.
• Avoid alcohol and heavy meals, which can contribute to dehydration and overheating.

What to Do in a Heat Stroke Emergency

Despite our best efforts, emergencies can still happen. If you find yourself in a situation where someone may be experiencing heat stroke, call 911 immediately. While waiting for emergency responders:

1. Move the person to a cooler place (indoors or a shaded area).
2. Remove any excess clothing.
3. Cool the person down using:

• A tub of cool water or a shower
• A fan while misting with water
• Ice packs applied to the armpits, neck, back, and groin
• Wet towels on key areas to help lower body temperature
