How does sun cause damage to our skin?
Dr. Busso addresses this question by answering that "we have two forms of sunlight, the visible one and the invisible sunlight. The invisible form has the ultraviolet light type A [UVA] and type B [UVB], which are our major concern. What they can produce is suntan, sunburn, skin cancer, premature aging, also eye damage, like cataracts, damage to the immune system, and even allergic reactions."
Dr. Shapiro follows up by adding "UVB is a much stronger radiation than UVA, and UVB is more absorbed by the epidermis than the deeper dermis where UVA is absorbed. In terms of your average daylight., around twelve noon is the strongest sun of the day, most of us know that, it’s about 90% UVB at twelve noon. Earlier in the day it’s more UVA, towards the end of the day it’s UVA as well. So UVB is a much stronger radiation, however, UVA can cause skin cancer, as well."
Sportin' the Sun Screen
Summer is the time for outdoor exercise, but exciting as this may be for sports lovers, it does mean that you have to take extra care to protect yourself from that sun.
There are different types of sports out there. There is golf, tennis, baseball, swimming, running, people are power walking with even their baby strollers, now that’s a big thing, too, and skiing. What is the correct product for some of these activities?
Dr. Bellman states "People are in a hurry. They want to put their sunscreen on and they want to go out the door and do their thing. Sunscreen is supposed to be put on the body twenty to thirty minutes before you actually leave the house to do your outdoor activities. So technically, if you’re going to put it on and then go sweat and exercise, it may burn your skin, it may sting your eyes, it may actually be very greasy and you may have trouble holding a ball or a bat, or what have you. So you have to think of all these things ahead of time when you’re buying the sunscreen in the store."
