Solar Ultraviolet Radiation Danger At Ski Resorts – Part 1 of 3
Solar Ultraviolet Radiation Danger At Ski Resorts. Skiers and other out of doors enthusiasts need to be aware that factors such as weather conditions and time of day can cause considerable alteration in the levels of ultraviolet (UV) radiation during the winter, researchers say. They analyzed data collected between 2001 and 2003 at 32 high-altitude ski resorts in western North America. They also interviewed matured guests at the resorts and looked at their clothing and equipment in order to assess their level of sun protection.
Average UV levels at the ski resorts were moderately low but heterogeneous substantially, the researchers found. Clear skies, time close to noon, and more hours of daylight as the ski season progressed were the strongest predictors of increased UV radiation. The researchers also found lass associations between higher UV radiation and altitude, longitude and temperature.
However, elevated UV levels were not associated with increased use of sun-protection measures, such as sunscreen lip balm, application of sunscreen 30 minutes before skiing, wearing a culmination cover with a brim, or wearing gloves. The study did find that as UV levels increased, adults were more likely to wear sunscreen with a nominal 15 SPF and to reapply it after two hours, and more likely to wear sunglasses or goggles. Men were more likely than women to use sunscreen.
