The answer to this question is extremely important to the indoor tanning industry because, if UVR can be scientifically proven to cause CMM in humans, the survival of the industry is in jeopardy. On the other hand, if the scientific evidence shows that exposure to sunlight, UVR or a tanning device does not cause CMM, there will be no reason for health-conscious individuals to forgo the incontrovertible benefits of UVR exposure—such as maintaining an optimal vitamin D level year-round—in the carefully controlled environment of a professional indoor tanning salon. So, which answer is correct?
Coincidental vs. Causal Correlation
Research reveals that there is only a coincidental correlation—not a causal correlation—between UVR and CMM; therefore, neither sunlight nor a tanning device can be blamed for causing this disease. Think of this in terms of a post hoc ergo propter hoc relationship, in which it is incorrectly believed that one event comes before and, therefore, causes another when, in fact, the two events were examples of coincidental correlation—not cause and effect. Here are some examples of why coincidental correlation does not prove causation:
- Sleeping with one’s shoes on is coincidentally correlated with waking up with a headache.Therefore, going to sleep with your shoes on is the cause of headaches.
- Since the 1950’s, both the atmospheric CO2 levels and crime levels have increased sharply.Therefore, atmospheric CO2 causes crime.
However, the logical concept of post hoc ergo propter hoc requires that one event always occur before the other event in order to prove causation. For example, in order to prove exposure to UVR causes CMM, there must be a “molecular signature” of damage to the melanocyte genome each time there is UVR exposure and no such molecular signature has ever been demonstrated. Instead, the sunscreen industry, the dermatology community and vested-interest advocacy groups such as the Skin Cancer Foundation have used a coincidental correlation between sunlight/UVR/tanning devices and CMM to link them together. This is, at best, an example of the post hoc ergo propter hoc logical fallacy in action and, at worst, an example of scientific evidence being manipulated in order to promote a deceptive agenda (i.e. selling products and services, such as sunscreens containing UVA filters).
So, why is exposure to sunlight, UVR or a tanning device blamed for causing CMM given the fact that there is no valid scientific evidence (i.e., no molecular signature,) to support this premise? In order to understand the coincidental correlation that has led to this claim, you must understand how melanocytes function within an epidermal melanin unit (EMU).
I have heard this question numerous times over the years.
The misconception by most though is that UV rays from tanning will affect your developing baby. This statement is false.
UV rays, whether indoors or out, do not penetrate below the layers of the skin.
Some doctors advise against sun exposure in general while pregnant, others suggest with moderation.
The fact is that while pregnant, increases in your core body temperature can be harmful.
Tanning itself is not the problem. What you do need to monitor is how hot you get while tanning. Anything that will raise your core body temperature, such as hot tubs, saunas and tanning beds can be harmful to your unborn baby, including general over-exposure to the sun. Overheating (also called hyperthermia), particularly during the first trimester, can result in developmental damage to your baby. During pregnancy, your skin’s sensitivity to burning may be increased, so you should start with short sessions until your body is tanned. Stay cool and drink plenty of fluids to prevent light-headedness and dehydration, whether indoors or outdoors.
If you are using a tanning bed, make sure there is adequate ventilation in the tanning room and if you get uncomfortable or start to feel too warm, then get out, whether your session is over or not.
Many unknowing tanners always ask the question:
Will burning first give me a darker, better tan?
Burning causes damage to the surface layers of the skin. Many people say ” my burn turns to tan “. This myth is very dangerous. Tanning and burning are two totally different processes.
Burning leads to premature aging, sunspots, drying, flaking and peeling of the skin, and should be avoided at all cost! A burn may heal and disappear at the same time a tan is developing , giving you the appearance that your burn is turning tan. You’re actually causing damage to your skin. Repeated damage could lead to some forms of skin caner.
The tanning process is not something that can be rushed. It may seem like nothing happened, but it can take up to 48 hours for melanogenisis to begin. Adjust your session slowly till you reached your desired color. Remember everyone is different, and while building a base tan 48 hrs is the recommended time between sessions.
New research has shown that vitamin D deficiency is epidemic in American adults today, suggesting that up to 90 percent of North Americans are vitamin D deficient. It is likely that over-usage of sunscreen in climates and seasons when sunburn is not a possibility has contributed to this epidemic. This is especially significant because:
- A 2006 systematic review of 63 studies on vitamin D status in relation to cancer risk has shown that vitamin D sufficiency can reduce one’s risk of colon, breast and ovarian cancers by up to 50 percent. The landmark paper, published in the February 2006 issue of The American Journal of Public Health, is the most comprehensive paper on vitamin D written to date.
- Additionally, vitamin D deficiency is a leading cause of osteoporosis, a disease affecting 25 million Americans which leads to 1 million hip and bone fractures every year. In elderly individuals, such fractures are often deadly. Encouraging everyone to wear sunscreen all year long in any climate undoubtedly is contributing to this problem, as vitamin D is necessary for the body to properly process calcium.
- While environmental correlations have established for years that people in sunny climates have lower risks of many forms of cancer, in recent years the mechanism by which Vitamin D slows or retards the growth of tumor cells has been researched and identified. It was once thought that only the kidneys could produce active vitamin D, but we now know that many cells in the body perform this function, including cells in the breast, prostate, colon, brain and skin.
- Research has shown that the active form of vitamin D, when present in cells throughout the body, inhibits the growth and spread of abnormal cells, including cancer cells.
What Does Indoor Tanning Have To Do With Vitamin D?
Exposure to UVB from sunshine is the body’s natural way to produce vitamin D, accounting for 90 percent of vitamin D production. Dietary “supplements” are just that: Supplemental ways to produce vitamin D.
Research has shown that people who utilize indoor tanning equipment that emits UVB – which most tanning equipment does – also produce vitamin D. And studies have also shown that indoor tanning clients have higher vitamin D blood levels than non-tanners.
While the North American indoor tanning industry promotes itself as a cosmetic service, one undeniable side-effect of that cosmetic service is vitamin D production. Even though it is not necessary to develop a tan to produce vitamin D, this should be considered: Because research suggests that the risks associated with sun exposure are related to intermittent sunburns, it is credible to believe that the benefits of regular, moderate non-burning exposure outweigh the easily manageable risks associated with overexposure.

The Golden Rule of tanning is “Don’t Ever Burn.”
People who are Skin Type 1 (never tan, always burn) should never tan using UV tanning equipment; however, these individuals may take advantage of sunless tanning equipment.Start building your tan slowly and use short exposure times to build up a tan over time.Ask the tanning salon if the lamps in the beds are newly replaced so you can adjust your tan time accordingly.Use an SPF on any areas that you do not want to tan (as a towel, shirt, etc only deflects about 5% of UV light).Protective eyewear is required.Moisturize your skin regularly both pre- and post-tanning.
A review with the salon operator will determine your skin type. Use the corresponding recommended exposure schedule posted on each bed as a guideline for your initial tanning session and any subsequent weekly or monthly sessions.Tan in moderation.Read the warning label posted on each bed to understand the risks of overexposure.
If you have never used a particular piece of UV equipment, be sure to ask for a complete instructional walk through prior to tanning.
1. You need to prepare your skin to tan. Dry skin doesn’t tan as well, dry skin, reflects light, instead of absorbing it. This can mean you will get a sunburn easier as well. By using lotion your skin is moist, and healthy and supple, ready to take in the sun.
2. You need to protect your skin! Most of the premium brand lotions are high quality lotions. Many lotions are aloe vera based, which is widely known for its positive effects on the skin during moderate to heavy sun exposure. When using a tanning lotion, the main active ingredients are those which accelerate your skins ability to generate melanin. The process by which the skin tans – simplified – is the conversion of Tyrosine, to Melanin, by the UVA portion of light. Your body produces some Tyrsosine, but not enough to actually keep up a high-quality unit like the matrix, especially with its low UVB output. It’s similar to having the fastest brick wall building crew, and no bricks. So by not using lotion, you are going to have to a lot more, to get the same tan. Chewing up MORE minutes and increasing your total UV exposure which puts added stress on the skin, especially without the moisturizing qualities of lotion to take care of your skin.
3. You want to prolong your tan. By using lotion, along with some other very basic skincare principles like exfoliating during your shower, your skin will stay healthy, and thus stay tanned longer. This means less tanning, using less minutes tha you are paying for, and keeping the same look.
So by ignoring the Prepare/Protect/Prolong factors in using lotion, we end up with wrinkly un-tanned customers, that will go on to talk about how tanning is bad, when its just tanning like an idiot thats bad. Doing anything like an idiot is bad, you could drive your car with your feet if you want to, doesn’t means its a good idea!
Besides all the fun benefits like smelling good and anti-oxidants, lotion is absolutely imperitive to tanning. It would be like if you saw your little cousin brushing his teeth without toothpaste, you would think he’s being stupid. If he argued with you on the importance of toothpaste, you’d tell him he’s being retarded, yet you are not a dentist. It’s common sense, which isn’t so common these days. This is why I get frustrated with people when you have to “SELL” them lotion, rather than just show them the lotions, let them smell them, explain the features and the benefits of those features, and let them happily pick a favorite.
According to a new study, vitamin D deficiency in white Americans doubles risk of fatal stroke.
Nearly 7% of the white patients were vitamin D-deficient, compared with more than 32% of the black participants. Whites with too little Vitamin D had twice the risk of dying from stroke as whites with adequate levels of the vitamin, which is obtained from fortified dairy products, fatty fish and exposure to sunlight.
Erin Michos, M.D., M.H.S., the study’s lead researcher and an assistant professor of medicine at Johns Hopkins University School of Medicine in Baltimore, Md explains, “We thought maybe the lower vitamin D levels might actually explain why blacks have higher risks for stroke . “But we did not find the same relationship between vitamin D and stroke in blacks.”
After adjustment for confounders like A1C, diabetes duration and conventional cardiovascular risk factors, diabetes mellitus patients who had severe vitamin D deficiency were found 103% more likely to die from all causes, compared with those having higher levels.
Vitamin D is synthesised in skin with the help of sunlight. About 30 minutes of exposure to sun (maximum portions of arms, neck and head) is recommended. Also, recommended daily intake of vitamin D — 400-800 IU/day. However, some experts prescribe even higher dosages.
Stroke is the top three leading cause of death in the US, this illness kills about 140,000 people yearly and affects more than half a million lives for acquiring a permanent impairment.
The findings are scheduled to be presented at the American Heart Association’s annual scientific sessions in Chicago.

So UV exposure is actually good for you? You mean they were lying trying to sell all that sunscreen? Gwyneth Paltrow secretly suffered from a bone disorder.
The ‘Iron Man 2’ actress was diagnosed with the onset of osteopenia – a condition where bone mineral density is lower than normal – and was ordered by doctors to spend more time in the sun to boost her vitamin D levels.
She said: “I suffered a pretty severe Tibial plateau fracture a few years ago (requiring surgery) which lead the orthopedic surgeon to give me a bone scan, at which point it was discovered I had the beginning stages of osteopenia.
“This led my western/eastern doctors in New York to test my Vitamin D levels, which turned out to be the lowest they had ever seen, not a good thing. I went on a prescription strength level of Vitamin D and was told to spend a bit of time in the sun!”
Gwyneth – who has two children, daughter Apple, six, and four-year-old son Moses, with husband Chris Martin – admits the advice left her “confused” as she had always been told to stay out of the sun.
She added in her GOOP newsletter: “I was curious if this was safe, having been told for years to stay away from its dangerous rays, not to mention a tad bit confused.”
However, after following the doctor’s advice, the 37-year-old blond beauty managed to reverse her Vitamin D deficiency
Did you know that vitamin D deficiency is a leading cause of osteoporosis, a disease that affects 25 million Americans leading to 1 million bone fractures every year?
In elderly individuals, such fractures are often deadly!

Professional indoor tanning facilities do a better job teaching the correct usage of chemical suncreen than “sun scare” groups who manufacture and mass-market the product, according to the International Smart Tan Network. Our position is based on the following:
- The “Sun Scare” industry is promoting daily use of chemical sunscreen year-round in any weather. That is misbranding the product.
- Simply stated, sunscreen should only be used as a tool to prevent sunburn whenever sunburn is a possibility. It should not be used on a daily basis in climates and seasons when sunburn is not possible.
- Think of chemical sunscreen the same way you think of cough syrup: It’s a product you should use only when you need it. If a pediatrician told you to give your child cough syrup 365 days a year — even when they didn’t have a cold — would you do it? Yet that’s what those who mass-market chemical sunscreen and dermatology industry lobbying groups are telling you to do.
- The professional indoor tanning community teaches proper sunscreen usage more effectively than those who simply tell the public to wear the product 365 days a year: The tanning community’s approach is more credible and practical.
- Why all the deception from “Sun Scare”? Follow the dollar. Chemical Sunscreen sales have increased thousand-fold from millions to billions in sales with fear-based marketing. These manufacturers are not permitted to claim that their product prevents melanoma, so they pay dermatology groups to infer that it does, even though research doesn’t agree.
- To change their message from “use sunscreen to avoid sunburn” to “use sunscreen to avoid any UV exposure” Big Pharm and Derms had to convince people that any UV exposure is dangerous even though sun exposure is natural and intended.
