The Dark Side Of The Sun
"A few precautions and a little common sense can fend off the ill effects of sunlight and keep boating as fun as it ever was. Boaters, beach-goers and others spending time outdoors recognize the importance of using sunscreen lotions throughout the day. But most people look only for SPF ratings to block UVB rays. (SPF stands for "sun protection factor" and is measured by Food & Drug Administration standards for screening out UVB rays. There are not yet ratings for UVA screening. SPF numbers measure the amount of time you can remain in the sun using sunscreen, compared the time it normally takes one's skin to burn. A person who uses SPF 15 may be able to stay in the sun 15 times longer than if their skin was unprotected.)"
