Guest guest Posted April 24, 2007 Report Share Posted April 24, 2007 Dangers of Tanning Beds Apr 24, 2007 06:41 PDT By Dixie Medford, P.C.C.D http://classicbeautyconcepts.com/articles_dangeroftanningbeds.htm In the United States more than 1 million people a day invest both time and money to visit tanning salons. For years, having a tan has been synonymous with health and vitality. And for those who feared the safe alternative. Beware of claims like these. Ads that claim indoor tanning beds to be safer may be false. Recent studies show that the ultraviolet exposure received from tanning beds are just as harmful to the skin as outdoor sun exposure, leading to the same molecular alterations believed to be necessary for the development of skin cancer. In a study published by Baltimore's John Hopkins University School of Medicine individuals were exposed to full-body tanning treatments for two weeks. Only a small part of the buttock was covered to provide a control skin sample. During the final tanning session, one-half of the skin on the buttock was uncovered, thereby providing an area for examination after a single ultraviolet exposure. Skin biopsies, as well as blood samples, were taken from the participants after the first exposure and after the final exposure to determine the molecular alterations in the skin and blood. The DNA that is most commonly damaged by ultraviolet radiation and the protein that allows cells to slow down their reproduction process so that damage from ultraviolet radiation can be repaired was analyzed. The study found that relative to unexposed control skin, there was a significant change in the DNA in the skin biopsies. In addition, the change of the skin after just one exposure was similar to the quantity of change that occurred after the two weeks of tanning. Also, within 24 hours of the first tanning exposure the protein to assist in damaged skin was present in all layers of the skin. This was an indication that the body was trying to repair itself. When the body is trying to repair damage, there is the risk of a mistake in the repair process, which increases as the number of altered cells increases. If there is a " miss " ' in the cell repair process, subsequent replication of the altered cell yields a clone of abnormal cells, which may eventually appear as skin cancer. Dermatologists and public health professionals are concerned about the dangers of ultraviolet radiation from tanning beds and sun lamps. There are two types of ultraviolet radiation. They are Ultraviolet A (UVA) and Ultraviolet B (UVB). UVB has long been associated with sunburns while UVA has been recognized as a deeper penetrating radiation that causes more damage. Many older tanning devices used light sources that emitted UVB rays that actually caused burning. Aware of the harmful effects of UVB radiation, salon owners began tanning beds that emit mostly long wave UVA light sources. Advertising claims of, " No burning, no harmful side effects, and nor harsh glare " is just simply incorrect. Indoor tanning leads to the same molecular alterations believed to be necessary for the development of skin cancer as outdoor exposure. This year, more than one million new cases of skin cancer will be diagnoses in the United States alone. Over 50,000 of those will be diagnosed with melanoma, the deadliest form of skin cancer. Almost 8,000 people will die from melanoma. Melanoma can be the side of a dime and can metastasize to other organs and kill someone relative quickly. Studies show that too much exposure to the light source used in tanning beds can damage the retina. The continual overexposure can burn the cornea, and over time change the structure of the lens so that it begins to cloud, forming a cataract. There is no such thing as a safe tan. A suntan is the skin's response to an injury and every time the skin is exposed to ultraviolet rays it accumulated damage, as well as accelerates the aging process. The American Medical Association and the American Academy of Dermatology has warned people for many years about the dangers of tanning, both indoors and outdoors. Doctors and public health officials have recommended the following steps to minimize damage to the skin and eyes: TIPS TO AVOID UV DAMAGE Plan your outdoor activities to avoid the sun's strongest rays. As a general rule, avoid the sun between 10 a.m. and 4 p.m. Wear protective clothing Wear sunglasses that provide 100% UV ray protection Avoid the use of sun lamps and tanning beds.

Guest guest Posted April 25, 2007 Report Share Posted April 25, 2007 While I understand that these articles that we are being inundated with are for education, let's stop and think about this for a minute. Many who are writing these articles about the dangers of tanning beds are the same ones that say don't go out into the sun unless you have chemical sunscreeen slathered all over your body, always wear sunglasses, always wear a hat, etc. They are the ones that do not realize how important the sun is to health and well-being. The TRUTH is that it is the slathering on of the chemical sunscreens that might possibly be causing skin cancer AND people who are not healthy and are consuming hydrogenated fats/oils along with the SAD will usually have more problems with sunburn. People who consume healthy oils (mostly flax and coconut) will not burn as easily and, in fact, will most always tan. The sun and the rays the sun emits are not our enemy. Wearing sunglasses all the time is not a healthy idea. Most people need far more sun than what they currently get. Most people do not have healthy levels of Vitamin D and we are now finding out the importance of good Vitamin D-3 levels. As with anything, balance is the key. Tanning beds are safe IF they are used responsibly. They are actually great for those in the colder climates that don't see the sun as often as we in the South do. Use a low SPF natural tanning lotion (there are several good ones out there that do not contain harmful ingredients) and never tan for more that 10-15 minutes at a time. Unrefined coconut oil is great to use for a tanning oil. The tanning salons will tell you that you will only get results with " their " sun tanning lotions. They are all full of chemicals and are extremely expensive. I know a couple of doctors that actually use the beds (very limited time exposure) without using any tanning lotion because they do not have the time to get out in the sun. They are quite healthy! This is just another situation where we are not being told the truth and that things are not always as they seem.

While tanning beds use the same kinds of ultraviolet light as the sun, the proportion of UVA and UVB are different. Most tanning beds emit 95% Ultraviolet A and 5% Ultraviolet B. Some beds use UVA only. Most tanning salon owners promote their beds by emphasizing that they only emit ultraviolet A (UVA) light. UVA rays are thought to be safer than ultraviolet B (UVB) rays, which cause burning.However, new research shows UVA light received in a tanning bed may be up to 10-times more than the amount people normally receive from the sun. Many experts agree that exposure to UVA should be avoided as much as possible. It distorts and damages DNA strands, causes moles and some types of skin cancer, causes skin aging and is more likely to cause sunburn. It is the kind of radiation that creates and secretes melanin, allowing tanning to take place.UVA causes more skin aging than UVB, is not blocked by sunscreens, and causes the most dangerous type of skin cancer – melanoma. Why increase the danger of tanning beds by using so much UVA? It is the kind of radiation that releases the melanin created by the UVB and makes it combine with oxygen to create the tan. While there are definite indications of the danger of tanning beds, the truth is that they haven't been around long enough for the jury to be in. In a decade or so, the cumulative effects will become clear. In the meantime, everyone has to decide for himself about the danger of tanning beds. Tanning beds typicaly damage DNA more than moderate sunlight exposure. Tanning beds and sun lamps emit 93% to 99% UVA radiation This is three times the UVA radiation given off by the sun Before discussing harmful effects of tanning beds, we must be familiar with the components of ultraviolet light and how it affects our skin. Sunlight contains two types of ultraviolet (UV) light: UVA and UVB. UVA rays consist of longer wavelengths that penetrate " deep " into the dermal layer of skin.Limited exposure to UVA rays causes skin to tan; however experts agree that exposure to UVA can lead to long- term skin damage. UVB rays' wavelengths are much shorter, affecting the outermost layers of skin. Tanning beds and sun lamps generally emit 93% to 99% UVA radiation This is three times the UVA radiation given off by the sun (http://www.wraltv.com/features/healthteam/1998/0520-sunscreen/). http://www.aad.org/public/Publications/pamphlets/DarkerSideTanning.ht m In a recent study published in the Journal of the National Cancer Institute, women who visited tanning salons more than once a month were about 55- percent more likely to develop melanoma. People think that tanning beds are safe. That they are a safe alternative to sunbathing. But studies have shown those claims are not true. There is no such thing as a safe tan. Skin damage at earlier ages is becoming more common with the use of tanning beds and lamps. More pre-cancerous lesions are being found in 20 and 30 year olds. UVA goes deeper into the skin. Sun lamps and tanning beds mainly give off UVA radiation. The lights act as a radiation multiplier. This increases the risk of skin cancer. UVA radiation is classified as a human cancer-causing agent. The harmful results caused by radiation from tanning lamps were determined to include three types of damage to DNA. Cyclobutanepyrimidine dimers (CPDs) were induced, oxidized and hydrated pyrimidines were " distorted " , and breaks were found in the single-strands. It was also discovered that the induction of these kinds of DNA damage occurs just before the development of skin tumors (Woollons,Clingen, Price, Arlett, & Green, 1997). Another study conducted in Sweden also concludes that tanning beds are a major factor in the development of malignant melanoma. Different people,all under the age of 30, were included in the study. The data concluded that the people who used tanning beds more than 10 times a year were seven times more likely to develop malignant melanoma than those who did not use tanning beds. Researchers estimated that by the year 2000, the risk of developing skincancer for those who did not use tanning beds would be one out of every 97 persons, and that the chances for those who did use tanning beds would be one out of every 13 persons (http://winonanet.com/health/articles/1996/feb/tan.html). The study also concluded that melanoma risks are increased by 300% forthose using tanning beds, and that the risks increase by800% for those who use tanning beds more than 10 times a year (http://www.hlthmall.com/tanning.html). What scientific research has been discovered on the effects of artificial tanning equipment? Studies regulated by medical researchers consistently report a number of interesting facts about the relationships between artificial tanning equipment and skin cancers. Studies prove that exposure to UV radiation is a risk factor for cutaneous malignant melanoma. One study reviewed that approximately 80% of the radiation emitted by tanning lamps is in the UV range, proving tanning beds to be carcinogenic, another study of Caucasian women with melanoma reported that women who had a history of sunburns had an increased melanoma risk. The reports also concluded that tanning beds resulted in increased risks for developing melanoma. Study of the UV radiation emitted by tanning beds: A Dermatology Department in the United Kingdom conducted a study examining DNA damage in human fibroblasts, cells that give rise to connective tissue, after they were exposed to artificial tanning lamps. During this experiment, a comet assay was performed in which cells UV-detecting cells were embedded into two different types of tanning beds to detect the amount of radiation emitted. In the tanning bed, the UVA radiation was measured at 85-100W/m2, and the UVB radiation was found to be 16-19W/m2. The radiation emitted by the sun was also measured using the same radiometers on a sunny day with the temperatures at about 25-24o C. The UVA radiation was 10-28W/m2, and the UVB radiation was measured at 4 – 9.5W/m2. Thus, the amount of UVA radiation, which penetrates deeper into the skin, was anywhere from about 3-8 times greater in the tanning beds than in the light from the sun. This inevitably increases potential skin damage (Woollons, Clingen, Price, Arlett, & Green, 1997). The harmful results caused by UVB radiation from tanning lamps were determined to include three types of damage to DNA. Cyclobutane pyrimidine dimers (CPDs) were induced, oxidized and hydrated pyrimidines were distorted, and breaks were found in the single- strand It was also discovered that the induction of these kinds of DNA damage occurred just before the development of skin tumors (Woollons, Clingen, Price, Arlett, & Green, 1997). The scientists who conducted the study agreed that although the amount of evidence regarding the harmful effects of tanning lamps has been limited, it has recently been increasing. They concluded that it is highly likely that the lamps cause DNA damage that is directly related to the development of skin cancers, cutaneous effects, and damage to the immune system. They believe that the public should be warned about the dangers of using tanning beds. Medical researchers agree that artificial tanning equipment emits predominantly UVA along with some UVB radiation, UVA rays cause sunburns, and sunburns increase the chances that one will develop skin cancers, including malignant melanoma. Therefore, the conclusion can be made that tanning beds cause skin cancer. Scientists also agree that the best method of modification of potentially harmful behavior is to educate people of the risks of acquiring melanoma and to eradicate the perceptions of risks. http://www.vanderbilt.edu/AnS/psychology/health_psychology/Tanning.ht ml Some states require salons to provide UV-protective eyewear or have machine operators remain present throughout a client's session. Others require a sign on the booth warning people who always sunburn that tanning puts them at high risk for skin damage. Whatever the regulations, says Dr. Franzblau, there's no assurance they will be complied with. " I've taken teams of scientists into salons where not one requirement was being followed. " Other studies have shown that tanning salons frequently exceed " safe " UV limits. The average salon patron in North Carolina was recently found to exceed FDA limits by 95 mpercent. Is banning salons outright the only answer? Dr. Franzblau believes that eliminating tanning salons " would be 100 percent more effective " than regulating them. And it could save millions of lives. UVA radiation is classified as a human cancer-causing agent. The number of skin cancer cases has been rising over the years. Experts say this is due to increasing exposure to tanning beds, and sun lamps. More than 1.3 million new skin cancer cases are likely to be diagnosed in the United States this year. The number of cases of melanoma is rising also. Studies have shown that people who used tanning beds before the age of 35, have a melanoma risk eight-fold higher than people who have never used them. Even occasional use almost tripled the chances. Using commercial lights also more than doubled the risk. Melanoma, with a suspected link to UVA exposure, is often fatal if not detected early. A 2002 study of participants who used tanning beds, found increases in other types of skin cancer also. Those who use the tanning beds were: 2.5 times more likely to develop squamous cell carcinoma 1.5 times more likely to develop basal cell carcinoma and more likely to develop basal cell and squamous cell carcinoma, the younger they were when they began using these tanning devices When exposed to tanning beds, the skin becomes red immediately. This peaks at approximately 8hrs and continues for 24 to 48 hrs. Burning with blisters can occur with this type of tanning too, if not careful. When exposed to the rays, the skin tries to protect itself. It thickens and produces a substance called melanin. This pigment darkens cells and, over time, causes: premature aging of the skin an increased risk for skin cancer red, itchy, dry skin sagging, wrinkled skin burning of the skin and damage to the immune system But why is it that some people can tan for many years and still not show damage? People who choose to use tanning devices are greatly increasing their risk of developing skin cancer. This is especially true if tanning occurs over a period of years, because damage to the skin accumulates.In the United States, 1 in 3 cancers consist of skin cancer. warm regards, JoAnn Quote Link to comment Share on other sites More sharing options...
Guest guest Posted April 26, 2007 Report Share Posted April 26, 2007 I'm growing a little weary of this topic. I don't understand why it's so hard for people to understand that artificial sunlight is not good for you. With or without the evidence, it seems perfectly clear to me that UV rays coming from a light bulb cannot be good, in the same sense that heat from a microwave cannot be good. And the argument that you know doctors who do it? I also know doctors who smoke, that sure doesn't make smoking good for you.

Guest guest Posted April 26, 2007 Report Share Posted April 26, 2007 Again, I appreciate all the research. The American Cancer society knows nothing about cancer, skin or otherwise---it is a political organization----the same organization that tells us skin cancer is from the sun, the same organization that tells us that chemo and radiation are the only modalities that will benefit cancer. Skin cancer is just like other cancer and it is not necessarily from the sun. I could send in hundreds and hundreds of articles about how safe chemo and radiation are, but the fact is that chemo and radiation are not safe and more people die from the effects of conventional cancer treatment than the cancer itself. It is very, very difficult to find unbiased research, these days. Scientists are skewing results because Big Pharma is paying under-the-table and recently the FDA is getting more into bed with Big Pharma under the guise of getting quicker approval for so-called " much needed " drugs as long as Big Pharma pays more to the FDA. Doctors are allowing their names to be put to research without even knowing IF the research is correct or was done in a correct manner. My last post indicated that staying in the beds for a short time only is just as beneficial as working up to the 30 minutes that most salons promote. All cancer develops when the terrain of the body is not in balance. People who are really healthy and by that I mean do not consume the SAD, hydrogenated oils, sugar, white flour, pre-packaged foods, etc. almost never have to be concerned with skin cancer and many don't even use sunscreen because they just do not burn. Tanning beds have been around for a long time. Much more than 10 years as I believe they probably hit the US market in the early '70s but were used in Germany as early as 1906 The reason that the jury is still out is because they cannot really find good hard evidence that the tanning beds cause cancer. They are speculating that since they believe the sun causes cancer, so do tanning beds. It's the chemicals in the sunscreen that are most likely causing the concerns but no one wants to go there. Why? Because the chemical sunscreen business is a multi-billion dollar business AND has the support of Big Medicine. What would happen if they decided than skin cancer may actually develop because of the chemicals found in the sunscreens that they have encouraged (and put fear into) everyone to slather on day in and day out?? Would make them look kind of dumb, wouldn't it? And, many companies would be put out of business unless they got the chemicals out---something they are not willing to do. Get a bottle of suntan lotion and then do research on the chemicals. We must learn to think out of the box and realize that in most health concerns what the multitude (conventional medicine) says is usually incorrect. Also, someone wrote about it making sense that artificial light is bad. If possible you may want to do some research on infrared and light therapy. By the way. No one is arguing and good conversations back and forth are actually good for education and research. It sharpens our thinking and makes us do research. Of course, everyone must make their own choices and do what they feel is best for them. It is when we " stifle " information, just because all the so-called " research says " , that we are in danger of possibly not knowing the real truth. ) Be Well~ Loretta Quote Link to comment Share on other sites More sharing options...
Guest guest Posted April 26, 2007 Report Share Posted April 26, 2007 Point well taken. Well thought out " arguing " can be a way of learning. And, if we didn't have differing opinions, it would be a boring world! Thanks! , " JoAnn Guest " <angelprincessjo wrote: > > , " Tina " > <mommyon731@> wrote: > > > > I'm growing a little weary of this topic. I don't understand why > it's so hard for people to understand that artificial sunlight is not good for you. With or without the evidence, it seems perfectly clear to me that UV rays coming from a light bulb cannot be good, in the same sense that heat from a microwave cannot be good. And the argument that you know doctors who do it? I also know doctors who smoke, that sure doesn't make smoking good for you. > > > Are you all here to learn about good health or are you here to > argue about it?? > > We're here to argue about it. <LOL This is a typical alternative > medicine forum and if you've joined very many of them, you are aware > that there are numerous differences of opinion on almost any topic.
