For sun safety the American Academy for Pediatrics recommends:
Avoiding sun exposure, and dress infants in lightweight long pants, long-sleeved shirts, and brimmed hats that shade the neck to prevent sunburn. However when adequate clothing and shade are not available, apply a minimal amount of suncreen with at least 15 SPF (sun protection factor) to small areas, such as the infant's face and the back of the hands. If an infant gets sunburn, apply cold compresses to the affected area.
For All Other Children:
- The first, and best, line of defense against the sun is covering up. Wear a hat with a three-inch brim or a bill facing forward, sunglasses (look for sunglasses that block 99-100% of ultraviolet rays), and cotton clothing with a tight weave.
- Stay in the shade whenever possible, and limit sun exposure during the peak intensity hours - between 10 a.m. and 4 p.m.
- On both sunny and cloudy days use a sunscreen with an SPF of 15 or greater that protects against UVB and UVA rays.
- Be sure to apply enough sunscreen - about one ounce per sitting for a young adult.
- Reapply sunscreen every two hours, or after swimming or sweating.
- Use extra caution near water and sand (and even snow!) as they reflect UV rays and may result in sunburn more quickly.
