Summer in South Florida brings serious sun exposure risks. Learn how to prevent sunburn, dehydration, and heatstroke in children with tips from Miami Pediatrics.
The Miami sun can be beautiful — and dangerous. Heat-related illness and sunburn are common reasons kids end up in urgent care every summer. As summer temperatures rise, families in Miami love spending time outdoors. From beach days and backyard BBQs to park playdates and sports camps, kids are soaking up the sunshine. But without the right precautions, that sunshine can quickly lead to serious heat-related illnesses, including sunburn, heat exhaustion, and even heatstroke.
At Miami Pediatrics, we want to make sure your child’s summer is filled with fun, not fevers. Here’s how to protect them from the dangers of too much heat and sun.
Understanding the Risks of Summer Heat in Children
Children are more vulnerable to heat-related illnesses because:
Their body temperature rises faster than adults’
They sweat less efficiently, making it harder to cool down
They may not recognize or communicate symptoms of overheating
They're often too busy playing to drink enough water
What Is Heat Illness?
There are three main types:
Heat Cramps – Muscle pain or spasms due to heavy sweating and salt loss
Heat Exhaustion – Signs include fatigue, headache, nausea, dizziness, and heavy sweating
Heatstroke – A medical emergency: hot, dry skin, confusion, rapid pulse, fainting, or seizures
Call 911 immediately if you suspect heatstroke.
How to Prevent Heat Illness in Children
Stay Hydrated
Encourage frequent water breaks — every 20 minutes during active play
Offer electrolyte-rich drinks (like Pedialyte) if sweating heavily
Avoid sugary or caffeinated drinks like soda or energy drinks
Plan Outdoor Time Wisely
Avoid outdoor play during peak heat hours: 10 AM to 4 PM
Schedule playtime in shady areas or under umbrellas/canopies
On very hot days, plan indoor activities during midday heat
Dress for the Heat
Choose light-colored, loose-fitting clothing
Use breathable fabrics like cotton or moisture-wicking blends
Always bring a hat and sunglasses when going outside
Preventing Sunburn: The Pediatrician-Approved Way
What Is SPF?
SPF stands for “Sun Protection Factor.” An SPF of 30 means it will take 30x longer for skin to burn than without sunscreen.
Our Sunscreen Recommendations:
Use broad-spectrum SPF 30+
Choose zinc oxide or titanium dioxide formulas — especially for young children or sensitive skin
Prefer lotions over sprays for better coverage and reduced inhalation risk
Reapply every 2 hours and after swimming or sweating
Special Notes by Age:
Babies under 6 months: Keep out of direct sun; use clothing and shade instead of sunscreen when possible
Toddlers & preschoolers: Apply 15–30 minutes before sun exposure; make it part of the routine like brushing teeth
School-age kids: Let them help apply it themselves to build independence — and don’t forget the ears, back of the neck, and feet!
Teens: Educate about skin cancer risk and visible skin damage; recommend matte or fragrance-free sunscreens they’re more likely to use

Watch for Warning Signs of Overheating
If your child is outdoors and you notice any of the following, act fast:
Extreme thirst or dry mouth
Fatigue or irritability
Flushed or hot skin
Headache or dizziness
No longer sweating
Vomiting or confusion
Move your child to a cool place, give sips of water, and place cool, wet cloths on their body. If symptoms worsen, seek medical attention immediately.
