Summer Safety 101: Sun, Heat, and Water Safety for Kids

Summer means longer days, backyard sprinklers, and family trips to the pool or the lake — and as a pediatrician, it's my favorite season to see happy, active kids in the office for their check-ups. But summer also brings its own set of risks: sunburn, heat illness, and water accidents are among the most common (and most preventable) reasons kids end up needing urgent care during these months. Here's what every parent should know to keep the season safe and fun.

Sun Protection: More Than Just Sunscreen

Sunburns in childhood don't just hurt in the moment — they raise the risk of skin cancer later in life, so protecting your child's skin now really does matter for their future health.

For babies under 6 months, the best approach is simple: keep them out of direct sunlight altogether. Dress them in lightweight, breathable clothing that covers arms and legs, add a wide-brimmed hat, and rely on shade — a stroller canopy, umbrella, or tree cover — rather than sunscreen.

For babies 6 months and older, look for a broad-spectrum sunscreen with an SPF of 30 or higher. Broad-spectrum means it blocks both UVA and UVB rays, which is important because both contribute to sun damage. If your child has sensitive skin or eczema, a mineral (zinc oxide or titanium dioxide) sunscreen is usually the gentlest option.

A few practical tips that make a real difference:

Apply sunscreen 15 to 30 minutes before heading outside so it has time to bind to the skin. Reapply every two hours, and immediately after swimming, sweating, or towel-drying, since water and friction wear sunscreen away faster than most parents expect. Don't forget commonly missed spots — ears, the back of the neck, tops of feet, and part lines in hair. And remember that shade and clothing (UPF-rated swimwear and rash guards are great for long pool days) do a lot of the work that sunscreen alone can't.

Recognizing and Preventing Heat Illness

Kids are more vulnerable to heat than adults. They produce more heat relative to their body size, sweat less efficiently, and often don't recognize or communicate that they're overheating until they're already in trouble. That's why it's on us as parents and caregivers to watch for the warning signs.

Heat exhaustion can look like heavy sweating, pale or clammy skin, fatigue, dizziness, headache, nausea, or muscle cramps. If you notice these symptoms, move your child to a cool, shaded area right away, offer water, remove excess clothing, and use a cool, damp cloth to help bring their body temperature down.

Heat stroke is more serious and needs emergency care immediately. Warning signs include a body temperature above 103°F, hot and dry (or sometimes flushed) skin, a rapid pulse, confusion, or loss of consciousness. If you suspect heat stroke, call 911 right away.

The best strategy is prevention: schedule outdoor play for the cooler parts of the day (morning or early evening), take frequent shade and water breaks, dress kids in light-colored, breathable fabrics, and never — even for a few minutes — leave a child alone in a parked car. Vehicle interiors can climb to dangerous temperatures shockingly fast, even with the windows cracked.

Hydration deserves its own mention here: dehydration and heat illness go hand in hand. Encourage regular water breaks even before your child feels thirsty, since thirst often lags behind actual fluid needs, especially in younger children who get absorbed in play.

Water Safety: Constant, Close Supervision

Drowning remains one of the leading causes of unintentional injury and death in young children, and it can happen silently and in seconds — even in shallow water, and even when other adults are nearby. The single most effective prevention tool is designated, distraction-free adult supervision: one adult whose only job, for a set stretch of time, is watching the kids in or near water. Put the phone down, skip the conversation with other parents, and keep eyes on the water.

A few additional layers of protection matter too. If you have a home pool, four-sided fencing with a self-closing, self-latching gate significantly reduces drowning risk. Swim lessons appropriate to your child's age and developmental readiness build both skill and water comfort, though they're not a substitute for supervision. Life jackets — not inflatable arm floaties or pool noodles — are the right choice for boating, open water, or for any child who isn't yet a strong swimmer. And it's worth learning infant and child CPR; it's a skill you hope never to use but will be glad to have.

Bug Bites and Stings

Mosquitoes and ticks are more than just an itchy nuisance — they can carry disease, so a little prevention goes a long way. Insect repellent containing DEET (in age-appropriate concentrations), picaridin, or oil of lemon eucalyptus is safe for most children over 2 months old; always follow label directions for application and reapplication. After time outdoors in wooded or grassy areas, do a quick tick check, paying special attention to the scalp, behind the ears, underarms, and behind the knees. If you find a tick, remove it promptly with fine-tipped tweezers, grasping close to the skin and pulling straight up.

The Bottom Line

Summer is meant to be enjoyed, not spent worrying. A little preparation — sunscreen in the beach bag, a hydration reminder before the sprinkler comes out, eyes on the pool, and a repellent check before the hike — covers most of what keeps kids safe this time of year. If you have questions about sun
