With the summer and its heat approaching, almost everyone will be out in the sun more than they were during the winter.
For 9 million Americans, being outside and in the sun is not just for summer fun – it’s a part of their job.
Workers in farming, landscaping, construction, recreation and even postal workers will spend hours in the sun – and consequently be exposed to potentially harmful levels of ultraviolet radiation.
Ultraviolet radiation, and specifically UVB, is the main environmental hazard to the outdoor worker. Most workers’ shifts include the peak intensity hours of UV exposure – 10 a.m. to 2 p.m. Since this type of radiation – UVB – easily penetrates clouds, it can reach worrisome levels even on days where little sun is visible. It easily passes through glass and can be reflected into areas of apparent shade.
UVB penetrates through the tough, dead outer layers of skin, into the replicating layers.
