Rep Power: 26 | Is a tan a "sign" of health? This “must read” article shows that facultative pigmentation, i.e., a “tan” is a “sign of health” rather than a “sign of skin damage” (as the dermatologists love to say). The "bottom line" is that a “tan” is a “visible surrogate” for having a sufficient vitamin D level. No tan = vitamin D insufficiency/deficiency. A tan = vitamin D sufficiency. Print this article and “share” it with your clients. Skeletons show rickets struck the Medici family Indoor life and poor nutrition condemned the children of Florence's rulers to bone disease. “Poor children … were living in small houses, and they were running around outside,” she says, but elite parents “wouldn’t have wanted their children to have tans, because that would suggest they had to go outside”. http://www.nature.com/news/skeletons-show-rickets-struck-the-medici-family-1.13156 |

Rep Power: 22 | Re: Is a tan a "sign" of health? Yup, I have said this for a long time. I go one futher - A tan is part of the regulation of Vitamin D as much or more as it is a method of protection against over exposure. Which is sort of what they say. |

Rep Power: 20 | Re: Is a tan a "sign" of health? I have always said that the "truth" in the healthiness of tanning is on the side of the tanning industry. We just need a courageous and forceful voice to proclaim it. Where is that voice going to come from? |

There is no reason for a scientist to submit a research paper showing the benefits of tanning and a lot of reasons to submit papers showing the opposite. All you can do is present the facts to people in your sphere of influence. One of the points I always make is that the development of facultative pigmentation (a.k.a., a tan) is "contravolitional" , i.e., taking place without conscious thought or action. Then I ask them to "try" two experiments: The first is to expose their skin to a controlled dose of UVR and "try" not to tan and the second is to slather on a sunscreen containing a UVA filter and "try" to tan. Next, I "educate" them about the difference between the protection afforded by facultative pigmentation (i.e., it protects the nucleus of the DNA) and a sunscreen (i.e., the "lies" on the surface "trapping" heat and containing harmful chemicals). The "proof" is that the "gold standard" for showing the efficacy of a sunscreen is to compare how well it does relative to facultative pigmentation. Finally, I point out that the UVR-avoidance message is only scientifically applicable to two groups. Skin type 1 individuals and individuals with a genetic defect that prevents them from developing facultative pigmentation. |

Rep Power: 20 | Re: Is a tan a "sign" of health? Who cares if the Tanning Industry is self promoting? Good grief! We are so beat down as an industry, we are actually afraid to promote the business we make our living off of. We are not the first industry to get on the "it's bad for you" list. That list includes: milk, eggs, meat, carbonated beverages, fast food, energy drinks, fossil fuels, and the list goes on and on. Do these industries go and hide under a rock? Do they think they need to go hire a bunch of scientists to promote their cause? No, and many of these don't have as much going for them as this industry does. We should promote ourselves without apology. Check out how Coke has handled their addition to the "list". This industry could learn something. |
