Guest guest Posted January 8, 2012 Report Share Posted January 8, 2012 Good info Sara!One thing about skin cancer (of which melanoma is one form - most skin cancers are non-melanoma) is that it can also develop on areas of skin not exposed to sun. Research has found that low levels of selenium is correlated with the development of skin cancer (and that selenium is preventative): http://www.ncbi.nlm.nih.gov/pubmed/20805887You can search in pubmed for additional articles on this topic - what amazes me is how old some of the articles are - i.e., this is not a new concept. However, it is consistent with the approach to medicine in the U.S. of not addressing root causes and making money from selling things that deal with symptoms. Anyways, I have found that I can spend a significantly longer time in the sun without getting sunburned since I've been taking selenium. I have lily white skin and I used to get blistery sun burns from spending 30 minutes in the sun. I have only gotten sunburned once in the past 7 years and that was when I spent literally all day working in the yard during the summer. Selenium is also very important for thyroid function. Here's a good article on the topic:http://thyroid.about.com/library/weekly/aa072000a.htm You can take too much selenium (a symptom is orange hair) and always you should check with your doctor and let them know all the supplements you are taking or are considering taking. B. I read in two books on Vitamin D, which had tables for sunlight dosing, that at our latitude in Dallas, 40 minutes is about right for winter at high noon, on a clear sunny day. North of us, into OK, it starts to fade out and no Vitamin D will be made in the skin at all. I'm sure there must be tables on the Internet somewhere to see how long to stay out at different times of the day in different seasons. I remember one book used UV level as part of the formula. You can get that on the Internet for your location, predicted for that day at noon. I had no idea that age, weight, and medications can affect the making if Vit D, so one should read up on it before " taking the sunshine. " Of course, family history or personal history of any skin cancer should be taken into consideration. I did know that skin tone affects the making of Vitamin D, and insufficiency is found more predominantly in African Americans, who need to stay in the sun longer to get equivalent amounts. Always research this and know your appropriate " prescription strength " before dosing! :-) I think a very good site is the Vitamin D Council's website which was started by Dr. Cannell. http://www.vitamindcouncil.org/ There are many interesting articles on research on the site and noted in their monthly e-newsletter. I'm amazed at what I've read about a possible link between a mother's insufficiency of Vit D levels and autism. And many articles about research on possible benefits of Vit D against some cancers, it's purported ability to boost the immune system. I've been saddened to learn of the rise in the incidence of childhood rickets. Children are being slathered with sunblock and kept out of the sun so much that we are going the wrong way now, and they don't get enough sun. Dr. Cannell writes of parents being charged for child abuse, and then they find out that it's a lack of VItamin D that lead to bone loss and fractures or breakage. He's trying to get the medical community to step up to the plate on this. It takes forever to turn things around. Although I take supplements and have a good blood level finally, there is nothing like spending time outside in the sun, but knowing how long to stay and then get in the shade or cover up or go inside. I'm sure the " real deal " has special benefits you can't find in a pill. All JMHO.

Guest guest Posted January 8, 2012 Report Share Posted January 8, 2012 Dr. Cannelloni indicates that latitude, age, skin tone and other factors all influence vitamin d absorption. Our latitude of 32 degrees N is very close to the 35 degree cutoff that he gives for winter sun. Given that many of us on this list have auto-immune disease, this might be a fine line to draw. Personally, I err on the side of caution and consider our area to be suboptimal for vitamin d absorption in the winter months. Please note that March is historically the month where there is the least amount of vitamin d absorption from the sun. Also, you will want UVB rays and not the UVA rays for vitamin d. One of Dr. Cannell's article wrt latitude. http://www.vitamindcouncil.org/about-vitamin-d/how-to-get-your-vitamin-d/uvb-exp\ osure-sunlight-and-indoor-tanning/ Krispin Sullivan, one of the pioneers of vitamin d research, indicates that any latitude higher than 30 degrees N dies not have consistent UVB rays in winter. http://sunlightd.org/ Susie Sent from my iPhone > > > I read in two books on Vitamin D, which had tables for sunlight dosing, that at our latitude in Dallas, 40 minutes is about right for winter at high noon, on a clear sunny day.

Guest guest Posted January 8, 2012 Report Share Posted January 8, 2012 Interesting, but I have to go down my own path with Knowledge, and Dr. Mercola is supported by Dr. Spurlock, but Dr. Spurlock alsoIs good about questioning…but I did find out about Mercola from him……and started reading his website info. I will consider your opinion. Thank you.

I do not trust Dr. Mercola, but many do. He does not know everything about many subjects that he has articles about his website. IMO I've been researching and following this vitamin D information for many years and have no reason to believe that Dr. Mercola is on the cutting edge of the research.

Guest guest Posted January 9, 2012 Report Share Posted January 9, 2012 Whew. Since Houston is at 29*95*, I guess I didn't waste my hour in the sun today! Sure felt good. I am one who supplements Vit D but still feels best when getting sun as well. Once it begins to get hot, I start monitoring my time outdoors very carefully and build up to where I can spend an hour actually tanning outside. Haven't burned since I was a kid. Had several severe sunburns then. Marti > > > Dr. Cannelloni indicates that latitude, age, skin tone and other > factors all influence vitamin d absorption.
