Summer in Georgia brings sunshine, longer days, and plenty of opportunities to enjoy the outdoors—but it also brings soaring temperatures that can pose serious health risks. Among the most common and preventable summertime health issues are heat exhaustion and dehydration.
At MedNow Urgent Care, we want you and your family to enjoy everything summer has to offer safely and responsibly. Let’s take a closer look at how to stay protected from the heat and recognize the warning signs before a minor issue turns into a medical emergency.
Understanding the Risks: Heat Exhaustion and Dehydration
Before diving into prevention, it’s important to understand what heat exhaustion and dehydration are, how they develop, and why they can be dangerous—especially during the summer months.
Heat exhaustion occurs when your body overheats and struggles to cool itself down. This typically happens after prolonged exposure to high temperatures, especially when combined with high humidity and physical activity. It’s considered a milder form of heat-related illness, but without proper intervention, it can progress to heat stroke, which is a life-threatening condition.
Dehydration is what happens when your body loses more fluids than it takes in. This can disrupt your body’s natural balance of salts and electrolytes and interfere with normal functions. In hot weather, dehydration can happen faster than you might think, especially if you’re sweating a lot and not replenishing fluids.
Common Symptoms to Watch For
Knowing the warning signs of heat exhaustion and dehydration can help you take quick action and avoid more serious complications.
Signs of Heat Exhaustion:
- Heavy sweating
- Weakness or fatigue
- Dizziness or lightheadedness
- Headache
- Muscle cramps
- Cool, pale, or clammy skin
- Nausea or vomiting
- Fainting
Signs of Dehydration:
- Dry mouth and throat
- Extreme thirst
- Dark yellow urine or infrequent urination
- Dizziness
- Confusion or irritability
- Fatigue
If you or someone you know is experiencing these symptoms, it’s important to cool down, hydrate, and seek medical attention if conditions don’t improve quickly.
Who’s Most at Risk?
While heat-related illnesses can affect anyone, some groups are more vulnerable, including:
- Children and infants, who may not recognize the signs of dehydration or be able to communicate their needs
- Older adults, whose bodies may not regulate temperature as effectively
- People with chronic health conditions like heart disease, diabetes, or respiratory issues
- Athletes or outdoor workers, who are often exposed to extreme heat for long periods
- Individuals taking medications that can affect hydration or heat tolerance
Being aware of who is most at risk helps families, caregivers, and employers take extra precautions when necessary.
Practical Ways to Prevent Heat Exhaustion and Dehydration
Staying safe during the summer heat doesn’t have to be complicated. A few simple habits can go a long way in protecting yourself and your loved ones from heat-related illness. Here’s how you can stay cool, hydrated, and healthy:
- Drink Fluids Consistently
Don’t wait until you feel thirsty—by that point, you may already be mildly dehydrated. Sip water throughout the day, especially when you’re outdoors or physically active. If you’re sweating heavily, consider adding electrolyte-rich drinks like sports beverages to help replace lost salts and minerals.
Important: Avoid alcohol, soda, and drinks with caffeine, as these can increase fluid loss and contribute to dehydration.
- Dress Smart for the Weather
Choose breathable, lightweight clothing that’s light in color. Dark clothing absorbs more heat, while loose-fitting garments help air circulate and cool your body. Hats with wide brims and sunglasses can also help shield you from direct sunlight.
- Plan Around Peak Heat
The hottest part of the day—usually from late morning to mid-afternoon—is when your risk for heat exhaustion is highest. If possible, schedule outdoor work or exercise early in the morning or later in the evening when temperatures are cooler. When that’s not an option, take frequent breaks in shaded or air-conditioned spaces.
- Don’t Skip Sunscreen
While sunburn itself doesn’t cause dehydration, it can make it harder for your body to stay cool. Apply broad-spectrum sunscreen with an SPF of 30 or higher at least 15 minutes before going outside, and reapply every two hours or after swimming or sweating.
- Listen to Your Body
Fatigue, dizziness, or feeling overheated are signs you should stop, cool down, and hydrate. Don’t try to push through discomfort—your body is warning you for a reason. Rest in the shade or indoors and rehydrate before continuing any activity.
- Protect Kids and Pets
Children and pets are particularly vulnerable to heat. Make sure they stay hydrated, dress appropriately, and take breaks from the sun. Never leave children or pets in a parked vehicle, even for a short time. The temperature inside a car can rise dangerously high within minutes.
When It’s Time to Seek Medical Attention
Most cases of heat exhaustion and mild dehydration improve quickly with rest and rehydration. But some symptoms indicate the need for professional medical care.
Seek urgent care or emergency help if:
- Symptoms do not improve within 30 minutes of cooling down
- Vomiting prevents you from keeping fluids down
- There is confusion, fainting, or loss of consciousness
- Body temperature reaches 103°F or higher
- Skin becomes hot and dry instead of sweaty (a sign of heat stroke)
