FOR IMMEDIATE RELEASE
(Free-Press-Release.com) April 24, 2010 -- As a longer ray, UVA is less wavy than UVB, which means UVA can penetrate the skin to the deeper layers without causing significant damage to the top skin layers. However, UVB's short, tight rays are more intense.
UVA and UVB light waves cause skin to tan outdoors. As previously mentioned, these same light rays can be replicated in special lamps used in tanning equipment. Therefore, it is important to understand in detail the difference between UVA and UVB.
1. The penetration depth of ultraviolet light plays an important part in the tanning process. Notice below how far into the skin UV light penetrates. On that basis, where do all these rumors about internal organs being cooked from the inside out come from?" The answers may be numerous. However, despite the facts, rumors about the disastrous effects of UV light abound to this day.
Three types of ultraviolet light exist
• UVA -- Up to 2 rnrn (dermis - 2 mm is the thickness of a computer diskette.) UVA penetrates deeper than any other type of ultraviolet light. As you can see from UVA's penetration depth, it would be impossible for your liver to cook and explode from ultraviolet light. Now think about this - What about that little baby inside Mama's tummy? Is it going to get a pretty good tan? The answer is no. Why? Because ultraviolet light never gets there! So why is there such great concern about pregnant women tanning? There are several reasons.
a. The first is heat. Heat (infrared rays) travel a lot farther than ultraviolet light. Pregnant women are advised to use caution with saunas, jacuzzis, and the hot summer sun because it will make them uncomfortable. Your tanning equipment when operating all day long during the busy season, can get pretty hot. If heat makes a pregnant woman uncomfortable, the baby will be uncomfortable too. In the middle of the busy season, you might consider restricting pregnant tanners to tanning in the morning hours when your equipment is a little cooler.
b. The second factor is liability. Let's just say your pregnant customer loses her little baby two months after she completed her tanning package with you. Who do you think she's going to blame? Although tanning equipment was never manufactured to cook internal organs and little babies, she may not know any different. As a guideline, when you learn of a new pregnancy, take some time out to reeducate the customer regarding the tanning process. Let her know about the potential for the heat to make her uncomfortable. Explain how that ultraviolet light doesn't penetrate very deeply into the body. Also consider getting the expecting mother's family doctor or OB-GYN involved in the tanning process. If you get a doctor's approval, then you can allow them to tan. Make sure you attach any approval to that person's client profile card.
c. Other concerns include physical complication. Women in advanced pregnancy could experience difficulty using tanning equipment because most units would be too small or cramped for a mother close to delivery. Still, other medical professionals believe that, because ultraviolet light exposure stimulates the production of vitamin D in the body, tanning is a positive activity for a pregnant woman, especially in the first trimester. Many salons simply prohibit pregnant women from tanning. If you salon decides it will allow pregnant women to tan, we suggest you have any expecting mother check with her doctor prior to allowing her to tan in your salon. If she decides not to tan, you should offer to keep her tanning package valid until after her pregnancy.
• UVB - Up to .03 mm (epidermis) Although UVB cannot get past the top skin layers, it bombards them with energy and is much more likely to cause sunburn than UVA. That's why UVB is often called the "burning ray," and UVA is called the "tanning ray." Tanning units use a carefully controlled mix of both rays to help prevent indoor tanners from burning as easily or as quickly as they could by tanning outside, and also to create cosmetic tans that minimize the risk of skin damage.
• UVC - From .01 mm to .10 mm (epidermis) UVC will be referred to only incidentally, since tanning equipment is not designed to release any UVC. UVC is typically associated with the germicidal lamp that your local hair salon uses to sanitize their equipment. It is also used to purify water. Don't get the idea though that turning the equipment on can sanitize tanning beds. This is not possible.
2. Intensity is described in terms of watts/cm2 and also plays a factor in the tanning process. Ultraviolet lamps continue to shine brightly well past their useful tanning life. This is because the ultraviolet strength or intensity deteriorates over time. The FDA and many state governments are concerned about energy intensity when it comes to replacing your tanning lamps. They want to ensure that your replacement lamps are compatible in terms of the energy output. We'll discuss this in a later chapter. Note too that the farther away you are from the light source, the less intense your exposure will be.
3. Joule, pronounced "jewel," is a unit used to describe energy, and is used to calculate a very precise amount of irradiation that a patient receives. Joules are determined by the mathematical formula milliwatts/cm2 (that is, the intensity or strength) multiplied by the amount of time, and divided by 16.69.
