While contemplating my youth, growing up on our farm and ranch on the Utah/Nevada border, I mused on the amount of sunlight exposure that the hard summer work required. I was in the fields much of the time and spent a lot of time moving irrigation water, bucking hay bales and building and repairing fences. When the work allowed it, I shed my shirt until the sun became uncomfortable and then donned my cowboy hat and a long-sleeved shirt to protect against getting too much of that wonderful UV light. Some work, such as throwing hay bales on wagons, did not allow a bare body, because alfalfa hay is very scratchy. Much of the time, however, I was able to soak up the sun, going shirtless whether driving a tractor or chasing down recalcitrant cattle and sheep on my horse. My hands were often in the earth as I planted gardens and barley and alfalfa fields. Occasionally, I overdid the sun exposure and paid the price with a sunburn, but that was an infrequent occurrence. My friends called me “the brown man” although I am a blue-eyed, light skinned Caucasian. My tan was very deep; hence the moniker.
Those halcyon days of my youth were summer days, and I was never ill in that season; all of that sunlight kept me well, and it also helped to keep my mood elevated. Melanoma was never a worry for me or for the other farm boys and girls who lived in that area, and I have heard of no one who grew up there who ever contracted the disease, although they had the same ethnicity as I. Of course, lack of melanoma was to be expected, because people who spend much of their life in the sun are far less likely to contract melanoma than those whose stay indoors. For example, Diane Godar and her colleagues have presented evidence that outdoor workers, while receiving 3-9 times the sunlight exposure as indoor workers, have had no increase in melanoma since before 1940, whereas melanoma incidence in indoor workers has increased steadily and exponentially.  
This cogitating on my youth was triggered by reading an article entitled A senior moment: Get ‘down and dirty’ — Gardening is good for you! It discussed all the benefits of gardening and related some research regarding its therapeutic use:
Exercise that strengthens both the upper-and lower-body muscles, and especially hand strength
Reduces heart rate
Lowers blood pressure
Exposes the body to sunlight (hooray) to reset the circadian rhythms and combat depression
Promotes better nutrition
Gives a better sense of time
Of course, some of these benefits of gardening are really benefits of sunlight, as mentioned in the article. However, there may be another factor at play; when we connect with the earth, it improves our health, including heart health and mood through a transfer of electrons from the earth to our bodies.
What have we lost as we have adopted our sedentary, indoor lifestyles? Among other things, we have lost our good nutrition, our sunlight exposure and our contact with the earth. It is no wonder that working in a garden has such beneficial effects on our health! It gives us back at least some of our basic human health needs. So if you don’t have a garden, find one and get out in the sunlight!
Having been reminded of some of those vital needs, I am anticipating with alacrity my upcoming week at my Nevada ranch, where I will rusticate with my wife Vicki and my friends, Drs. Bill Grant and Adiel Tel-Oren. We will be soaking up the sunshine, feeling the dark mountain soil, eating nutritious foods and exulting in the beauty of the aspens and pines. We will also be renewing friendships with the birds, the ducks, the deer, the Elk, the wild turkeys and other wildlife that have no worries about us, because we don’t kill and eat them.
Sunlight, peace and friendships—it doesn’t get any better than this!

SUNLIGHT EXPOSURE CORRELATES TO A LOWER RISK OF MELANOMA.
I’ve been writing on this FACT for some time, and an impressive 2015 paper corroborates it. Published in the scientific journal Dermato-Endocrinology, the paper makes some very interesting comments, all based on excellent research:
By Marc Sorenson, EdD, Sunlight Institute
Let’s revisit the need for appropriate nutrition in preventing melanoma death.
It has been well-established that melanoma is not caused by sunlight exposure, despite the sunphobes’ protestations to the contrary. There are numerous research papers that indicate melanoma is considerably less frequent among those who are regularly exposed to sunlight than among those who avoid it.     (The references cited here are only a few of the many papers that corroborate the fact that melanoma is less common among those who embrace the sun.)
More than two years ago I read of ongoing research by Dr. Pelle Lindqvist—reasearch indicating that greater exposure to sunlight resulted in longer life. I made several attempts to contact Dr. Lindqvist, but was unsuccessful. However, one of his colleagues answered my query and informed me that the research would not be completed later on and then be published. The results are now available, and they are impressive.
During a 20-year period, the subjects in the study who avoided sun exposure were twice as likely to die of any cause compared to those who had the highest sun exposure, and the researchers made this statement: “In both models the summary sun exposure variables showed a ‘dose-dependent’ inverse relation between sun exposure and all-cause death.”
The results of the investigation were recently published in the International Journal of Cancer, and demonstrated that regular sunlight exposure was not associated with either overall melanoma risk or risk at different body sites. To the contrary, the highest sunlight exposure predicted a 44% decreased risk of melanoma on the head and neck when compared to the lowest exposure.
In addition, when sunlight exposure to the upper limbs was assessed, the highest exposure was associated with a decreased risk of melanoma of 34%. The authors stated, “Our results suggest that occupational sun exposure does not increase risk of melanoma, even of melanomas situated on the head and neck.”
Stated another way, the authors might have suggested that sunlight exposure protects against the risk of contracting melanoma. In reading this research, I was reminded of a statement by Dr. Frank Garland during his presentation at a vitamin D conference I attended several years ago. He said, “melanoma is a disease of sedentary, indoor office workers.” He was absolutely correct.
Those who have bought the propaganda of the American Academy of Dermatology may consider this information quite surprising, but in reality it is just one more in a long line of scientific investigations pointing out several reasons that melanoma is not caused by sunlight exposure: (1) Most melanomas occur on areas of the body that are seldom exposed to sunlight. (2) As sunscreen use has increased, melanoma has also increased. (3) Outdoor workers have far less risk of melanoma than indoor workers. (4) As the populace has left outdoor work and moved indoors, profoundly reducing sunlight exposure, melanoma has increased exponentially.
For those interested in reading further regarding these statements and also searching the references, they are contained on previous posts on this site. In the meantime, let’s take advantage of some non-burning sun exposure to protect ourselves against melanoma.
I’m grateful to the scientists from Australia who brought forth this information. Truth will ultimately prevail.

When considering those studies, it becomes obvious that increasing consumption of alcohol leads to increasing risk of melanoma. Millen’s research, by the way, defined many other nutritional factors that lead to either an increased risk of melanoma or a protection against the disease. I discussed those factors in an earlier post on nutrition and melanoma. http://sunlightinstitute.org/skin-cancer-and-nutrition%E2%80%94stop-blaming-sun
The latest research corroborates the findings of the two aforementioned studies. Jessica Kubo and colleagues investigated the effect of alcohol consumption on the risk of melanoma in a 10.2-year study. Several interesting observations emerged: (1) those who consumed 7+ drinks per week had a 64% increased risk of melanoma; (2) higher lifetime alcohol consumption was positively correlated to risk of the disease; (3) higher current alcohol consumption similarly correlated to a higher risk: (4) current alcohol intake also predicted higher risk; (5) a preference for white wine or liquor also predicted increased risk.
So you see, the idea that melanoma is caused by sunlight exposure is again refuted. We know that as sunlight exposure has decreased profoundly in the last 100 years, the risk of melanoma has increased exponentially. When sunlight exposure has decreased and melanoma has concomitantly increased, what more needs to be said? I have previously posted two blogs on this subject and believe that they entirely refute the claim that melanoma is caused by sunlight.http://sunlightinstitute.org/exposing-sunlightmelanoma-fraud-part-1 http://sunlightinstitute.org/exposing-sunlightmelanoma-fraud-part-2
It is time that we started using our heads and look for the real reason for melanoma. Alcohol is just one reason among many, and it is time to look to other deleterious lifestyles as being the real causes of this deadly disease.

In her latest publication, she and her colleagues show that holidays in sunny areas were significantly correlated to thinner melanomas, meaning that the cancers were less likely to progress and spread. There was a dose-response protection against thicker melanomas; in other words, the greater the number of weeks of sunny holidays, the greater less the risk of thicker melanomas. This correlation existed only for women. The good news, however, is that for both sexes,recurrence of excised melanomas was reduced an average of 70% in those who spent the greatest number of days in the sunlight.
I and many others have said for years that not only does sunlight not cause melanoma, regular non-burning sunlight is protective against contracting melanoma. This new research corroborates that fact.
A similar study on melanoma thickness and the risk of relapse was done in 2009 by Julia Newton-Bishop and colleagues. In that research, it was shown that subjects with higher vitamin D levels had thinner melanomas and a greater survival prognosis. Nevertheless, the results were not nearly as impressive as the study by Gandini, et al. Sunlight exposure per se appears to be superior to vitamin D levels per se in protecting against melanoma.
Sunlight exposure is the best and most natural way to produce large quantities of vitamin D in the human body, and we are learning that sunlight produces many health benefits beyond vitamin D production. This present research is another step forward in bringing sunlight back to its rightful position as mankind’s best friend.

In so many countries, sunlight is looked on with fear, and the press is constantly promoting that fear by warning that sun exposure in causing melanoma—an idea that is patently false.
Fortunately, in India not everyone is buying the sunscare propaganda. It is not uncommon to see articles in the Indian press expressing the concern that Indians, many of who have adopted the indoor lifestyles of western countries, are becoming severely deficient in vitamin D due to lack of sunlight exposure. One of those articles was recently published in the online version of India Today. The author, Nalini Ravichandran, correctly points out: “Scientific studies have proven that Vitamin D is like the ignition key to your car; the car won’t run unless you turn the key and ignite the engine. So get started in the right direction, before it gets too late.” In other words, seek the sunlight!
The author also laments the fact that 80% of Indians are now vitamin-D deficient. The only thing lacking in this excellent piece is a discussion of all the benefits of sunlight beyond vitamin D.
I applaud the efforts of the Indian press to bring the truth about sunlight to their populace. I have seen several articles in the past year all extolling the benefits of sunlight. Now, if only we could get the western press to catch up!

I have often stated that melanoma is more common in people with type-1 (non-tanning, pale) skin, and that moles correlate to a higher risk of skin cancer regardless of sunlight exposure. Now, new research shows that the genetic makeup that accompanies red hair–not the amount of sun exposure–also correlates to an increased risk of melanoma. Read the article.
So what does this mean? Let’s stop attacking the sun and start addressing the real causes of skin cancers: 1. the presence of many moles on the skin[i], 2. Underexposure to sunlight[ii], 3. Lack of colorful fruits and vegetables in the diet[iii], 4. Drinking alcohol[iv], 5. Consumption of dairy products[v] and 6. Environmental pollutants such as PCBs.[vi] (see below for references). And of course, we have just established red hair as a risk factor for melanoma.
Exposure to sunlight has decreased dramatically in the last century, and sunscreen sales have exploded. During that same time there has been a concomitant exponential increase in melanoma. How then, can anyone in their right mind say that sunlight exposure causes melanoma? GET SERIOUS! The idea that sunlight causes melanoma, of course, is great way to sell sunscreens. Follow the money and you will discover the reasons for the promulgation of the sunlight/melanoma nonsense. Non-burning sunlight is our greatest friend and health enhancer. Check with your doctor before you make any changes in lifestyle.

In this excellent article, Dr. Charles Reinert tells about how his mother contracted melanoma on her chest (an area where she seldom was exposed to sunlight) and died of the disease shortly thereafter. He makes the point, as I have done repeatedly, that regular sunlight exposure is associated with a decreased risk of melanoma. He also lists several additional diseases that increase with decreased sunlight exposure. An excellent read.
