Huh? I should spend more time in the sun?
Editor's note: Thanks to the hundreds of readers who pointed out a typo in the second-to-last paragraph. Sorry it took me so long to correct. Naturally Robert meant you can get enough daily vitamin "D" and not "C" if you spend 10 minutes in the sun.
One of the refrains I hear most often covering the health and science beat is: “You tell me one day something is bad for me and then it is good.” There are many legitimate reasons for this perception, and the story we have on tonight’s Nightly News is a fine example.
About three decades ago, dermatologists alarmed at the rising incidence of skin cancer began a campaign to get people to stop spending so much time in the sun, or at least to cover up with strong sunblock lotion if they did. The effort was enormously successful.
Now there is a big problem with it. When the sun’s rays (unfiltered by lotion) strike our skin, our bodies produce vitamin D. Scientists always knew vitamin D is critical for good health. Children not exposed enough to the sun can get a terrible disease called rickets. But around 1989 scientists began to discover that vitamin D played an important critical role in all the cells in the body, and they hypothesized that a lack of vitamin D could increase the risks for cancer.
Large population studies have now verified that people with low vitamin D levels indeed have higher levels of several common types of cancer, including colon and breast. Some of the best research comes from the Nurse’s Health Study and the Health Professionals Study -- two efforts run by the Harvard School of Public Health that have been following tens of thousands of people for decades. The latest study looks at cancer incidence in men. You can see the journal article here with references to past studies that came to similar conclusions.
And here is the editorial that accompanies the study results in the Journal of the National Cancer Institute. In addition to the Harvard study, two others came out today demonstrating an increased incidence of breast cancer in women with low levels of vitamin D. Those were presented at the annual meeting of the American Association for Cancer Research.
So how much vitamin D do we need? Based on these latest studies, experts now recommend a minimum of 1,000 units a day. We get about 200 from food and supplements usually contain 400. That is where the sun comes in. No one is saying people should get sunburned or even tan. But you can get 1,000 units of vitamin D by spending 10 minutes in the sun in the middle of the day with your arms and face exposed. Amazingly, with our automobile and indoor lifestyle many Americans do not get even that much.
So here is an example where the advice is changing not because of confusion, but because science is making genuine progress.

I am a patient with an autoimmune condition. Most all diseases that appear to have a low vitamin D nutrient also have an elevated vitamin d hormone, which is what we use. So, a person cannot claim to be deficient, unless the hormone is checked too. These diseases suffer from disregulated vitamin d metabolisms, which are caused from cwd bacteria, which use the vitamin d hormone to create proteins. Please check out www.marshallprotocol.com.

This, like everything else, is so typical of the medical community. If they cannot make up their own minds about what is or isn't good for us, then to whom do we turn for such advice??? It's like a crime scene, ask 10 people what they saw, and you will get 10 versions of the events. I long ago stopped paying attention to these people who come out with every scatter brained idea coming down the pike, a different one from one week to the next. I do what feels right for myself, in moderation....It doesn't take a trained medical professional to tell me that lying in the sun for hours on end and burning my skin to a crisp isn't good for me, common sense alone tells me that, and that advice is free.

Please make sure you get the full picture on Vit D. Vit D can be low because it is being converted rapidly into 1,25D (the hormone). I fyou have high 1,25-D levels you maybe having troubles with auto immune type illnesses but it is never discovered because docs. only measure the 25-D form. In these instances sun and supplementation are the worst things you can do; exacerbates your illness. By the time they test the 1,25D levels they are looking for signs of kidney failure etc. I can't explain the 'whole picture' here so go to www.marshallprotocol.com and read for yourself why people with autoimmune diseases have dysregulated levels of Vit D.

Dermotologists, like all groups, are not 100% in agreement on anything because the research is far from perfect or conclusive! Some say avoid sun and tanning beds -- and then offer "treatments" in their UV "machine" (e.g. - a tanning bed!) to treat psorisis -- at a much higher billing to insurance than a couple of visits to a tanning salon! Others prescribe expensive creams and follow-up visits -- again, instead of sun exposure from which they will not profit!
Still, as with all professions, there are those who are more openminded and even handed, and believe that "moderation" is the watchword to most things in life!
Don't sunburn, don't lie in the sun for HOURS AND HOURS (with babyoil and iodine like those of us of "a certain age!" used to), don't hit the tanning salon EVERY day.
But DO get full body exposure to Vit D producing Ultraviolet light at least 3 times per week -- in a tanning bed, or by the pool when the weather permits. And visit your doctor yearly for a check of your Vit D levels, any change in mole activity as well as appropriate screeenings for cancers and other health issues.
Since grade school, we have always known -- the sun is the life-giving force critical in the chain to keep us all nourished, breathing, and healthy! That hasn't changed.....

I mean I have been advocating that my patients use my UV therapy in my office because I know it helps with acne and psorasis. I have no problem with this after all I am making money from it. But to advocate that people go out and do something like get free sunlight out side is insane.

What about the people who drown in water? Is all water bad for you?
What about people who die from air pollution? Should we stop breathing?
Bottom line, if the sun was as bad as the dermatologists say, the human race would have never made it this far. Plain and simple.
And for a doctor to say that supplements can work just as well, it's just crazy. It's always better to get the natural version than a synthetic one ESPECIALLY in a case where the body produces it naturally.
Well, let's see. You can go outside for $0 or you can spend thousands of $$$ in doctor visits.
I wonder which would be better....FROM THE DOCTOR'S POINT OF VIEW?
Also, SKIN CANCER is a lot more scary sounding than it is. You can either get some sun and help fend off all sorts of internal problems (colon cancer being a very important issue) or avoid the sun and hope for the best.
Well, you can't see colon cancer so I think I'll pick sun exposure just like my friends the cave men did.

If Dr. Zimmerman would spend some time treating patients suffering from vitamin D-mediated diseases like osteoporosis, diabetes, cancer, coronary heart disease, multiple sclerosis, etc., perhaps he would understand that the adverse affects of underexposure to UVR constitutes an extremely serious health problem for Americans.
UVR-induced vitamin D is the "elephant sitting in the living room" that dermatologists refuse to recognize.
Perhaps the legal action against six sunscreen companies should be broadened to include the dermatology community to wake them up.
And perhaps an enterprising journalist will someday take a look at why dermatologists continue to advocate sun avoidance and slathering on a sunscreen every day no matter the time of day or season notwithstanding the fact that numberous studies have shown that this advice is not just "wrong" but deadly wrong.

There is still confusion with the UVB from tanning beds and the UVB from the Sun for healthy Vitamin D production. In the simplest of terms, when there isn't enough UVB available outside for producing necessary Vitamin D, the next best place for a healthy dose is a few minutes in a tanning bed a couple times a week. Moderation is healthy. One final note: The Vitamin D2 from vitamin supplements is not as healthy as the Vitamin D3 from UVB.

What most citizens of the World are not aware of is the politically managed 'dictate' of what is 'good' now or what 'will kill you' later.
Skin Cancer on the Rise?? I think not. More so the number of skin screenings at Doctor's offices being coded as 'pre-cancers' - and added to the tally of the 'National Skin Cancer Epidemic' (anything from a skin tab to genital warts and HPV) is included in the 'Skin Cancer Numbers'.
Bad News, Scare Tactics, Behavior Modifications / Environmental Barriers do more than mislead the public on gaining the best for their bodies; They FEED the machine - Bad News sells... So does Scare Tactics (just ask Big Pharma who funds the 'studies' that sell more sunscreen, wrinkle cream and doctor's visits) Grant Chasers of the Major Universities ~ where would THEIR money come from if they could not insist their intellects were needed to STOP THE WORLD from following common sense healthy habits?
Sadly, the evidence recently published by Dr. Li-E Wang and colleagues from the University of Texas M. D. Anderson Cancer Center in Houston, showing that Melanoma (the true killer cancer) .... "Our findings suggest that nonmelanoma skin cancer and cutaneous malignant melanoma have different etiologies in addition to UV exposure," [Dr. Wang and colleagues note.]goes unheralded. Certainly, overexposure (burns) to UV light are directly linked to Basal and Squamous Cell Skin Cancers - easily treatable. But MELANOMA? Genetics are the 'cause' for that ~ but you can't sell product to SAVE THE WORLD if you can't scare them with death.
Instead of educating the public of the how's and why's of COMMON SENSE use of Natural and Artificial UV.... the message has been SHUN THE SUN (or else...)
Every year I see people going onto beaches with their tubes of Sunscreen (SPF 50???) getting fried!! Weekend Warriors set free from the 9-5 work week letting their pasty white bodies be ASSAULTED by too MUCH of a good thing.
I am what's called a 'Tanner'. I use indoor tanning salons due to what is called S.A.D (Seasonal Affected Disorder) and here in the Mid-West using a superior quality tanning facility is the ONLY thing that keeps me from going 'postal'. You'd stand more of a chance of dying from taking MY parking space than skin cancer ~ if I could not regulate my body clock, increase my endorphins and seratonin levels and relax in UV LIGHT -
The reality is, is that physicians took an oath to never cause intentional harm to a patient. HMOs didn't. Big Pharma didn't. PhD's didn't --- but, that does NOT absolve them from the HARM being done to the world's population with the SunScare Propaganda shoved at us for the past 30 years. Politics and FUNDING should never take the place of the Hippocratic Oath!

Sunlight is a very natural thing. It has been around for a long as we have been on this planet. It's part of a natural and healthy lifestyle just like wholesome foods and exercise. And while the artificial tanning industry may try to exploit this research it's certainly not some giant marketing conspiracy (as another poster suggested).
The solution is moderation and good old common sense. Don't let yourself sunburn (they call it a burn for a reason). Don't bake yourself everyday trying to "tan". However you should go outside and walk for a little while in the fresh air and sunshine every day. Why is this so difficult to understand? Why do people have to make this into a big controversy?

Dermatologists care about excess sun exposure becuase they see people dying of skin cancer every day. One american dies every hour from skin cancer and there will be more than 1 million new cases this year in the US alone!
Many studies show that people get plenty of sun exposure in their day-to-day activities to have enough Vitamin D and, if you dont belive that, you can take Oral Vit D and not put yourself at risk for skin cancer. The myth that is being propogated re going to a tanning salon to get more UV for Vit D is just a scam to make money for the tanning industry.

Talk about people jumping to conclusions. I didn't, at any time while reading this article, read a statement saying that we should stay out in the sun, unprotected, for long periods of time. What this is trying to say is that you need moderation. Go sit outside on your lunch break, Park away from a store and walk in the sun instead of finding the nearest parking spot. The sun is good for you. And can I please point out... yes, skin cancer is on the rise, however, what about skin cancer before sun block was invented? Are we trying to say that because we know too much sun can cause skin cancer, there have been more incidents? Moderation in everything. Go outside, enjoy the sun...just be aware and don't let yourself get burnt.

This study is just one more example of people jumping to conclusions of the appropriate action based on correlation studies. Correlations do not imply causality. Many individuals, when presented with correlation data immediately assume the one of the variables causes the other. This is a dangerous assumption, which it appears the medical professionals involved in this study have made. Low levels of 25-D may appear in some disease states, but, until you know why that relationship exists, merely doing things to increase the 25-D may not helpful. What if some third variable which was not included in the correlation study causes both low 25-D and the disease. Wouldn't we all be healthier to find the cause of the disease and fix that? Then D levels would return to normal as health returned to normal.

Whoa there... how polarized we are on this important subject. Too much or too little UVB for adequate percent conversion of 7-DHC to vitamin D3 is easily defined, and metrology already exists to enable conservative non-erythemal (non-sunburn) doses of vitamin D effective solar or lamp irradiance.
Studies at Boston University and elsewhere show that it requires almost one MED (minimal erythemal dose) of UVB (adjusted for skin type) on at least 10% of your body to synthesize a "daily recommended dose" of 1000 IU vitamin D3. For a light skin type 2 this could range from 14 minutes at a strong noon summer UV Index of 10.0 to 28 minutes at a spring or fall UV Index of 5.0 (mid latitude USA). In winter almost all the 290-315nm vitamin D "rays" are gone.. and short exposures to UV lamps could be substituted for sun.
Darker skin types require proportionately more exposure for a similar D3 dose. ALL of this is for zero (no) SPF sunscreen lotion because even a 15 blocks >98% of vitamin D effective UV. Any continued exposure beyond a MED should be accompanied by appropriate sunscreen. And as stated in an above post... people with XP or people taking sun sensitive medications must avoid all UV exposure and rely on diet or supplements for vitamin D.
If in any doubt about your Fitzpatrick skin type relative to your tolerance to UV by all means consult a dermatologist. If you are a skin type 1 and/or have moles or are taking any UV sensitive medications then UV exposure is always a bad idea. Otherwise the MANY benefits of moderate UV exposure are generally considered to outweigh the various risks. Mother nature allowed us to evolve under her big UV lamp in the sky rather than to become extinct from it's irradiance.
The whole point of this (too long) post is to try and rationalize our thinking away from the all or none extreems conveyed above and reach a science based middle ground.

It is 5:51 pm in Gallatin, Tennessee. Robert Brazell just said on the news that women are not taking charge of their own health and should know warning signals for heart attacks. That is bull. It is the DUMB DOCTORS who should know the warning signals. In 1995 I had all the classic symptons, and saw my doctor who said I was suffering stress. At 3 am, before I had a chance to see someone else, I had a major heart attack and ended up with 6 bypasses. I was one of the lucky ones who has now survived for 10 years. Women trust their doctors and the doctors let them down because doctors still don't get it -- that women have heart attacks too. I am very much on my bandwagon to tell all the women I meet what to look for. For God's sake don't lay this off on women too. Get a grip man, we haven't studied medicine for 6 years like doctors do.
