Ultraviolet (UV) light levels in Iowa are already consistently reaching 6-7 (high) on the UV Index Scale. CDC recommends skin protection if the UV Index is 3 or higher. UV rays tend to be strongest from 10 AM - 4 PM. UV rays can damage skin cells, and most skin cancers are caused by too much exposure to UV light.Those older than six months should use a broad-spectrum sunscreen on exposed skin that filters both UVA and UVB rays, with a sun-protection factor (SPF) or at least 15. Re-apply every two hours or after swimming, sweating, or toweling off. Sunscreen is not recommended for babies 6 months and younger, so be sure to keep them out of the sun as much as possible.
More outdoor tips to limit UV exposure include:
• Stick to the shade! Use an umbrella, tree, or other shelter to stay out of direct sunlight.
• When possible, wear long-sleeved shirts and pants or clothing certified to offer UV protection.
• Wear a hat with a brim that shades your face, ears, and neck.
• Sunglasses protect your eyes from UV rays and reduce the risk of cataracts.
