Hi, I wanted to ask for the Vitamin D Council's opinion/views on this new research study from Yale University's Skin Diseases Research Center (which was published in the journal Science yesterday) that is making the science media rounds. The study argues that UV exposure can lead to chemical damage (not only radiation damage) to DNA in skin cells that can show up long after one has been exposed (up to three hours). Apparently the study used exposure to UVA only, not the Vitamin D-producing UVB. I suppose my concern arises from the fact that I get moderate sun exposure year round every 2-3 days through sunbed use in winter and natural sunlight in summer. And these researchers, as they always do, raised the specter of higher melanoma risk if a person is exposed, which of course worries me a lot (even though I have never burned). Thank you so much in advance for your reply!

    I feel compelled to make a statement here. Many of you know that I work at Yale University. I did not post this question. It is a good one, though, and it deserves an answer from someone who has a scientific background. Perhaps Dr. Cannell or Dr. Grant will please consider addressing this post. My own research indicates that melanoma is due to inconsistent sun exposure that leads to burning. Consistent sun exposure that leads to healthy vitamin D levels actually helps prevent melanoma. But, as you all know, I am not a scientist. So, it would be very beneficial for a scientific person to speak here. <3

    I totally agree with Rita Celone Umile about sensible sun exposure and hope that future research will negatively correlate it with melanoma
