The short answer
Use shade and protective clothing first, then apply a suitable broad-spectrum sunscreen to exposed skin. Reapply as directed, usually at least every two hours and after swimming or heavy sweating; sunscreen does not prevent heat illness.

Keep in mind
- Combine shade, clothing, a brimmed hat, and sunscreen on exposed skin.
- Choose broad-spectrum sunscreen and follow its label; UK advice also looks for SPF 30 or higher and at least 4-star UVA protection.
- Seek medical advice for severe burns or signs of heat illness.
Why use more than sunscreen?
The American Academy of Pediatrics recommends combining shade, protective clothing, a brimmed hat, and sunscreen on exposed skin.
Toddlers move between shade and sun, so several layers of protection are more dependable than relying on one measure.
How can I use shade, hats, and clothing?
Choose shade when the sun is strongest; in the US, the AAP advises limiting exposure around 10 a.m. to 4 p.m. when UV rays are strongest.
A tree, canopy, or umbrella can help, but shade does not block every UV ray.
A brimmed hat can protect the face, ears, and neck; lightweight clothing that covers the shoulders and arms also helps.
For longer outdoor play, consider clothing labelled with an ultraviolet protection factor (UPF).
What should I look for in sunscreen?
Choose a broad-spectrum sunscreen for exposed skin. AAP parent guidance advises SPF 15 or higher; many clinicians and products use SPF 30 or higher.
For sensitive areas or skin, a mineral product with zinc oxide or titanium dioxide may suit some families; stop use and seek advice if a reaction occurs.
Where should I apply sunscreen?
Apply it to exposed skin, including the face, ears, back of the neck, hands, and tops of the feet.
Be careful around the eyes, follow the product label, and do not spray directly onto a child’s face.
When should sunscreen be applied and reapplied?
Apply sunscreen before going outdoors according to the product label; reapply at least every two hours and after swimming, heavy sweating, or towel drying.
“Water-resistant” does not mean waterproof or all-day protection; follow the label instructions.
Does sunscreen prevent heat illness?
No. Sunscreen helps protect skin from ultraviolet radiation; it does not prevent overheating or dehydration.
Take shade and rest breaks, offer drinks, and reduce outdoor activity in very hot conditions; move an unwell child to a cooler place and seek medical advice.
Is sun protection needed on cloudy days?
Clouds do not block all ultraviolet radiation, and sand, water, and other bright surfaces can reflect it.
Do not rely only on a cool temperature or cloudy sky when your child will spend time outdoors.
What can I do today?
Before going outside, prepare a hat, covering clothing, and sunscreen for exposed skin. Choose shade for breaks.
Build reapplication into your outing, especially for the ears, neck, and tops of the feet.
When should I get professional help?
Seek medical advice for a large or blistering sunburn, persistent pain, repeated vomiting, unusual weakness, or other signs of heat illness.
If your child is confused, difficult to wake, collapses, or has a serious breathing problem after heat exposure, seek emergency help.
When to seek support
Some signs need emergency help; other concerns can be discussed with your child’s healthcare team.
- Blistering or extensive sunburn, repeated vomiting, unusual drowsiness, confusion, or a child who is very unwell in heat needs prompt medical advice; emergency symptoms need emergency care.
