Summer in Utah brings longer days, warmer temperatures, and countless opportunities to enjoy concerts, festivals, sporting events, fairs, and outdoor adventures. While spending time outside can be a highlight of the season, it also increases your risk of heat-related illnesses.
Heat exhaustion is one of the most common medical conditions treated at outdoor events during the summer months. The good news is that it’s often preventable—and when recognized early, it can usually be treated before it progresses into a more serious emergency.
Here’s what everyone should know.
What Is Heat Exhaustion?
Heat exhaustion occurs when your body loses too much water and electrolytes through excessive sweating. This typically happens after prolonged exposure to high temperatures, especially when combined with physical activity.
If left untreated, heat exhaustion can progress to heat stroke, a life-threatening medical emergency that requires immediate treatment.
Common Warning Signs of Heat Exhaustion
Recognizing the symptoms early can make all the difference.
Watch for:
- Heavy sweating
- Cool, pale, or clammy skin
- Extreme thirst
- Fatigue or unusual weakness
- Dizziness or feeling lightheaded
- Headache
- Muscle cramps
- Nausea or vomiting
- Rapid heartbeat
- Fainting or feeling like you might faint
Someone experiencing heat exhaustion may also appear unusually tired, have trouble keeping up with activities, or simply say they “don’t feel right.”
Who Is Most at Risk?
While anyone can develop heat exhaustion, certain groups are at greater risk, including:
- Young children
- Older adults
- Athletes
- Outdoor workers
- Individuals with heart disease or other chronic medical conditions
- People taking medications that affect hydration or body temperature
- Anyone spending extended periods outdoors during hot weather
High humidity, direct sunlight, and strenuous physical activity can increase the risk even further.
What Should You Do?
If you think someone is experiencing heat exhaustion:
- Move them to a cool, shaded, or air-conditioned location.
- Encourage them to sit down and rest.
- Loosen or remove excess clothing.
- Offer cool water or an electrolyte drink if they are awake, alert, and not nauseated.
- Apply cool, wet towels or ice packs to the neck, armpits, and groin.
- Continue monitoring them until they begin feeling better.
Many people improve with rest, cooling, and hydration. However, if symptoms persist, worsen, or the person cannot keep fluids down, they should be evaluated by a healthcare professional.
When Is It an Emergency?
Heat exhaustion can quickly become heat stroke if the body’s cooling system begins to fail.
Call 911 immediately if someone:
- Becomes confused or difficult to wake
- Stops sweating despite the heat
- Has a body temperature of 104°F (40°C) or higher
- Experiences seizures
- Loses consciousness
- Has hot, red skin
- Develops difficulty speaking or walking
Heat stroke is a medical emergency. Rapid cooling and immediate advanced medical care are critical.
Tips to Prevent Heat Exhaustion
A little preparation can go a long way.
Before heading to an outdoor event:
- Drink water throughout the day—don’t wait until you’re thirsty.
- Wear lightweight, light-colored clothing.
- Apply sunscreen and reapply as directed.
- Take breaks in shaded or air-conditioned areas.
- Avoid strenuous activity during the hottest part of the afternoon when possible.
- Eat regular meals to help maintain electrolyte balance.
- Limit alcohol, which can contribute to dehydration.
If you’re attending an all-day event, make hydration and rest part of your plan.
