ATLANTA (WAOK) – Someone has actually done a study to determine an umbrella works as well against the sun as it does to protect you from rain. The study, published in the Journal of the American Medical Association, finds umbrellas block up to 99-percent of ultraviolet radiation. For the study, researchers at Emory University in Atlanta randomly gathered 23 umbrellas from people at the school. On a sunny morning, UV measuring devices were used to determine how much of the sun’s radiation made it through the umbrella fabric to where the nose of a person using it would be. The champion was a travel sun umbrella which blocked 99-percent of UV rays. Regular umbrellas blocked at least 77-percent of skin damaging UV light. The darker the color the better the protection.
