Also, it is important to not be fooled by cloudy skies which actually only block as much as 20 percent of the UV radiation. A helpful step to reduce the risk for skin cancer is to use sunscreen. Do not forget exposed areas like the tops of the ears. Wearing a hat with at least a 3-inch brim all around is ideal for protecting one's neck, ears, eyes, and scalp. A baseball cap or visor provides only limited protection, but is better than nothing.
Sunglasses help protect the eyes.
It is important that they block 99 percent-100 percent of the UBA and UVB radiation. Check the label to be sure. Also, do not use the darkness of the lenses as a guide. UV protection comes from an invisible chemical applied to the lenses, not from color or darkness. Heat illness Working in hot conditions, indoors or outdoors, creates health risks.
