July in the Triangle is beautiful, busy, and blazing hot. With temperatures regularly climbing into the upper 90s and humidity that makes it feel even hotter, North Carolina summers can be tough on little bodies. While we never want heat concerns to keep your family from enjoying the outdoors, understanding how heat affects children and knowing the warning signs of heat-related, summer illness can genuinely be lifesaving.
At HealthPark Pediatrics, we believe informed parents are empowered parents. Here’s everything you need to know about keeping your children safe when temperatures soar this summer.
Why Children Are More Vulnerable to Heat
Children aren’t just small adults when it comes to heat tolerance. Their bodies handle heat very differently, and understanding why helps explain why extra precautions are so important.
Children have a higher body surface area relative to their body weight compared to adults, meaning they absorb more heat from hot environments. They also produce more metabolic heat during physical activity than their size would suggest. At the same time, children sweat less efficiently than adults, which reduces their ability to cool down through evaporation.
Young children in particular don’t recognize the early signs of overheating in themselves and are less likely to stop playing or ask for water when they need it. They rely entirely on the adults around them to monitor their condition and keep them safe.
Infants and toddlers are at the highest risk of heat-related illness because they cannot communicate discomfort and depend completely on caregivers for hydration and cooling. Children with certain medical conditions, those taking specific medications, and overweight children may also be more vulnerable to heat.
The Heat Illness Spectrum
Heat-related illness exists on a spectrum from mild heat cramps to life-threatening heat stroke. Knowing where your child falls on this spectrum helps you respond appropriately.
Heat Cramps: Heat cramps are the mildest form of heat illness and are caused by the loss of salt and water through sweat during physical activity. Your child may experience painful muscle spasms, usually in the legs, arms, or abdomen.
Heat cramps typically occur in active, otherwise healthy children during or after vigorous exercise in the heat. They’re a signal that your child needs to rest, cool down, and replenish fluids and electrolytes. Move your child to a cool environment, have them drink water or a sports drink, and gently stretch and massage the affected muscles.
Heat cramps alone don’t require emergency care, but they’re your body’s early warning sign that more serious heat illness could follow if you don’t take action.
Heat Exhaustion: Heat exhaustion is more serious than heat cramps and requires prompt attention. It occurs when the body can no longer compensate for fluid and salt losses in the heat. This is the stage where most parents need to be especially vigilant, because children can progress from seeming fine to heat exhaustion surprisingly quickly.
Symptoms of heat exhaustion include heavy sweating, cool and pale or flushed skin, fast and weak pulse, nausea or vomiting, muscle cramps, tiredness and weakness, dizziness and headache, and fainting or near-fainting.
Your child may seem confused, unusually irritable, or “not quite right.” They might stop playing suddenly or seem to run out of energy very quickly. Trust your instincts. If something seems off, take it seriously.
Immediate Response to Heat Exhaustion: Move your child to an air-conditioned environment or, at a minimum, to a shaded area. Have them lie down and elevate their legs slightly to improve circulation. Remove excess clothing and apply cool, wet cloths to the skin. Use a fan if available to promote cooling through evaporation.
Encourage your child to drink cool water or a sports drink in small, frequent sips if they’re conscious and not vomiting. Don’t give large amounts at once, as this can cause nausea.
Call your pediatrician or seek medical care if symptoms don’t improve within 15 minutes of cooling measures, if your child is vomiting and can’t keep fluids down, if they fainted or lost consciousness, or if symptoms seem to be worsening.
Heat Stroke: Heat stroke is a life-threatening emergency. It occurs when the body’s temperature regulation completely fails and core body temperature rises to dangerous levels, typically above 104°F (40°C). Heat stroke requires immediate emergency medical care.
There are two types of heat stroke. Classic heat stroke can occur even without vigorous exercise, simply from being in a very hot environment. This is the type seen in children left in hot cars or in homes without air conditioning during extreme heat. Exertional heat stroke occurs during intense physical activity in hot conditions.
Symptoms of heat stroke include very high body temperature (103°F or higher), hot and dry skin (in classic heat stroke) or hot and moist skin (in exertional heat stroke), rapid and strong pulse, confusion, slurred speech, or strange behavior, loss of consciousness, and seizures.
Critically, in heat stroke, sweating may stop. If your child is sweating heavily and suddenly stops while still in the heat and appears ill, this is a serious warning sign.
If you suspect heat stroke, call 911 immediately. While waiting for emergency services, move your child to a cool environment, remove clothing, and cool them as rapidly as possible using whatever means are available. Immerse them in cool water, apply ice packs to the neck, armpits, and groin, or use cool wet sheets and fanning.
Do not give fluids to a child with heat stroke, as they may be unable to swallow safely.
The Hot Car Crisis
No discussion of heat illness in children would be complete without addressing the danger of hot cars. The interior of a parked car can reach deadly temperatures within minutes, even on a mild day. On a 90-degree day, a car’s interior can reach 130°F in just 30 minutes.
Never leave a child alone in a parked car, even for a moment, and not even with the windows cracked. Heat builds up incredibly quickly, and children’s bodies heat up three to five times faster than adults’.
Develop habits to prevent accidentally leaving a child in a car. Keep a stuffed animal in the front seat as a reminder when your child is in the back. Put your phone, purse, or briefcase in the backseat so you always check the back before walking away. Ask your childcare provider to call you immediately if your child doesn’t arrive as expected.
If you see a child alone in a hot car, call 911 immediately.
High-Risk Times and Situations
Knowing when heat illness is most likely to occur helps you take extra precautions during vulnerable moments.
The hottest part of the day in the Triangle is typically between 11 AM and 4 PM. Schedule outdoor activities and sports practices for early morning or evening whenever possible during July and August.
Sports practices and competitions are high-risk settings. If your child participates in summer sports, make sure coaches and organizers follow heat safety protocols, including mandatory water breaks, reduced intensity during extreme heat, and monitoring of athletes for symptoms.
The first few days of a heat wave are particularly dangerous because the body hasn’t yet acclimatized to the higher temperatures. Be extra cautious and limit outdoor activity during the initial days of an intense heat wave.
Children returning to outdoor sports after a period of rest or illness are also at higher risk, as their bodies aren’t yet conditioned for the heat. Allow time to gradually reintroduce activity in the heat.
Hydration Is Your Most Powerful Tool
Most heat-related illnesses can be prevented or reduced in severity through proper hydration. And as we’ve discussed in previous HealthPark blogs, children are often dehydrated before they feel thirsty, making proactive hydration essential.
Encourage your child to drink water consistently throughout the day, not just when they feel thirsty. Before outdoor activity, have your child drink 8 to 16 ounces of water. During outdoor activity, encourage water breaks every 15 to 20 minutes, even if they don’t feel thirsty. After outdoor activity, replenish fluids based on how much your child sweats.
For prolonged physical activity lasting more than an hour, sports drinks can help replace electrolytes lost through sweat. However, for typical outdoor play, water is the best and most appropriate choice. Avoid sodas, energy drinks, and excessive fruit juice, as these don’t hydrate as effectively as water.
Make drinking water engaging for children by using fun water bottles, infusing water with fruit, or setting hydration goals and celebrating when they’re met.
Dressing for the Heat
What your child wears makes a significant difference in their ability to stay cool. Dress children in lightweight, loose-fitting, light-colored clothing that reflects rather than absorbs heat. Moisture-wicking fabrics designed for athletic activity help keep sweat away from the skin and promote evaporative cooling.
Always apply a broad-spectrum sunscreen with SPF 30 or higher before outdoor activities, and reapply every 2 hours. Sunburn significantly impairs the skin’s ability to regulate temperature, increasing the risk of heat illness. Wide-brimmed hats provide shade for the face, neck, and ears while allowing heat to escape from the head.
Creating a Cool Environment
When outdoor temperatures are extreme, having access to cool indoor spaces is essential. Keep your home as cool as possible during heat waves by using air conditioning, fans, and blackout curtains to block direct sunlight.
If your home doesn’t have air conditioning, identify cooling centers in your area where your family can spend time during the hottest hours. Many Triangle libraries, recreation centers, and community buildings serve as cooling centers during heat emergencies.
Keep play areas in shaded spots and use water play as a cooling strategy. Sprinklers, water tables, and pools provide both entertainment and effective temperature regulation.
Acclimatization for Active Kids
If your child will be participating in outdoor sports or activities this summer, allow time for their body to acclimate to the heat. Start with shorter, less intense sessions in the heat and gradually increase duration and intensity over one to two weeks.
Coaches and parents should monitor children closely during this acclimatization period and be especially alert for early signs of heat illness. Young athletes who have recently moved to the Triangle from cooler climates are particularly vulnerable until their bodies adjust to our humidity and heat.
Special Considerations
Children with chronic health conditions, including heart conditions, kidney disease, or those taking certain medications, may be at increased risk for heat illness. Talk to your pediatrician about specific precautions if your child has any underlying health issues.
Overweight children have a higher risk of heat illness because excess body fat insulates the body and makes it harder to dissipate heat. These children may need extra encouragement to hydrate and take breaks during outdoor activity.
Building Heat Safety Habits as a Family
The best heat safety strategy is one that becomes second nature. Create family routines around hydration, scheduled breaks during outdoor activity, and checking in with how everyone is feeling during hot weather. Talk to your children about the importance of telling an adult if they feel unwell, dizzy, or unusually tired during outdoor play.
Teach older children to recognize signs of heat illness in themselves and their friends and to seek adult help immediately if something seems wrong. This peer awareness can genuinely make a difference during sports practices and outdoor activities where children may be less closely supervised.
