Bone is deteriorating in our society. Why? Since the year 2000, there has been an 8,300% increase in vitamin D deficiency in children. Insufficient time playing outdoors and/or sunscreen use are the causes of this disaster. It is especially relevant to know that the skin produces vitamin D when it is touched by ultraviolet light (UV). (UV, of course, is a spectrum of sunlight, and of tanning beds and sunlamps.) And, the artificially-lighted environments that most children (and adults) live in, produce no vitamin D for bones. Vitamin D is critical for preventing osteoporosis, a fact that is most noteworthy for this discussion. Without vitamin D, weak bones develop in adults and rickets can develop in children.
Bone strength in children: Rickets is making a comeback.
Rickets is a horrible, disfiguring children’s bone disease. And, before the population became terrified of sun exposure, rickets was at one time considered to be eradicated. Hence, people are surprised to find out that the bones of children are deteriorating. Hence, rickets is making a frightening comeback, it is rearing its ugly head even in sun drenched southern states. That is probably because the children are inside, avoiding the sun and concentrating on their technology. Of course, disuse of the body during this sedentary state also causes loss of calcium, thus causing weakness.
Can “sun supplementation” stop or reverse bone loss?
Therefore, the latest research on UV supplementation is exceptionally important in this world of indoor artificial light. First of all, rats exposed to long–term low-dose ultraviolet irradiation showed an increase in bone formation rate. Furthermore, there was a decrease in resorption (bone breakdown). And, there was an improvement in bone mass content and bone mineral density without any adverse effects on skin. Consequently, this research shows that the concept of ultraviolet light causing skin cancer is incorrect. Also, it corroborates how effective ultraviolet light is in maintaining and increasing bone mass. For example, a Spanish study shows that women who are sun-seekers are protected from bone loss. They have only one/11 the risk of hip fracture as those who avoid the sun.
Bring the UV light inside to protect bone and enhance wellbeing.
In conclusion, this research demonstrated a concept that had never occurred to me. If we can’t bring the children (or adults) out into the sunlight, perhaps we can bring the sunlight inside to them. Also, it seems like a great idea to use low-intensity ultraviolet light indoors for northern climes where sunlight is scarce in the winter. I guarantee that it will also improve moods, reduce seasonal affective disorder and otherwise enhance the health. So remember regular, non-burning sun exposure when you consider a healthful lifestyle.

First of all, low-back pain is pandemic in much of the world. And, it is especially common in countries where most women wear clothing that prevents sun exposure to the skin. One of the first studies to show an association between LBP and reduced sun exposure was done in England: Northerners were 3-4 times as likely to suffer low-back pain as southerners. Of course, we know that there is less sunshine in the north.
Other low-back pain research shows similar results based on latitudes.
Hence, it is no surprise that research done in Southeast Asian countries shows an equally impressive result for sun exposure. Low-back pain increases from southern to northern latitudes, starting at 5º North (Malaysia – 8.8% low-back pain rate), continuing to 23º N (10.2% low-back pain rate), then 32º N (13%), and finally to 40º N (Beijing — 15.8%). Furthermore, another study by showed that vitamin D deficiency was common among those suffering from low-back pain. It was three-times more common than among those who did not suffer from low-back pain. The researchers stated, “The major determinant of hypovitaminosis D in our patients is limited sun exposure.”
Low-back pain research from Saudi Arabia and Pakistan
In addition, similar findings have been reported in Saudi Arabia and Pakistan. Researchers did a study on undergraduates in those areas. They researchers wanted to assess the students awareness regarding vitamin D deficiency associated with lack of sun exposure. These students often suffered from fatigue and muscular pain. Researchers concluded that many of them were acquainted with vitamin D deficiency, and some used a supplement. However, the investigators seemed to feel that supplements were not sufficient. They believed that sun exposure was the best method to maximize vitamin D levels.
In conclusion, they stated that the role of the sun, and the proper time and duration of exposure, could not be ignored. That is, if the students were to help effect a healthy and active society. Furthermore, they also indicated that since these students would be medical care givers in the future, their habits should be similar to the habits they intended to recommend to their future patients.
My conclusion about sun exposure and low-back pain.
In conclusion, it appears that sunlight, whether or not accompanied by vitamin D production, is effective for relief. Try a few minutes of non-burning sun exposure daily to ease the low-back pain. Remember how vital regular, non-burning sun exposure is for human health.

Melanoma risk between persons with high and low vitamin D levels
The risk directly associates with low levels of vitamin D. That is the conclusion of recent study published in the European Journal of Cancer. The investigators measured the blood vitamin D levels of 137 subjects who had been diagnosed with melanoma. They collected the blood samples at the time of diagnosis of the disease. Another group of 99 healthy subjects served as the control group. The investigators collected the samples of the control group between October and April. The scientists then compared the blood collections of the melanoma group with those of the control group. They then determined whether vitamin D levels had an association with melanoma risk.
The study produced convincing results regarding vitamin D and melanoma risk.
The results were as follows:
- The controls (no melanoma) had vitamin D levels 50% higher than the melanoma group (27.8 ng/ml vs. 18 ng/ml).
- 66.2% of the melanoma group had vitamin D “deficiency,” compared to only 15.2% of the health controls. The scientists defined vitamin D deficiency as being equal to or less than 20 ng/ml. So, the melanoma group had more than four-times the risk of deficiency.
- The scientists defined vitamin D “sufficiency” as being equal to or greater than 30 ng/ml. They found that only 7.4% of melanoma patients were sufficient, compared to 37.4% of healthy controls. Hence, the melanoma group had about one-fifth the likelihood of having sufficient D levels.
More scientific analysis on vitamin D measurements vs. melanoma risk
The scientists then adjusted the data for possible confounding factors such as age, sex and body mass. Then, they performed an analysis that showed the following:
- First of all, the science demonstrated a significant inverse association with vitamin D sufficiency versus deficiency. Those who had sufficient levels had only 4% of the melanoma risk when compared to those who were deficient! Hence, this demonstrates that those with the lowest vitamin D levels (after adjusting for confounding factors) had 25-times the melanoma risk!
- And, vitamin D insufficiency vs. deficiency was significantly inversely associated with melanoma. Those who were insufficient had a definite advantage over those who were deficient. They had only 13% of the melanoma risk.
Now, this is the most important point about melanoma risk:
In addition, this research proves conclusively that sun deprivation is a major cause of melanoma. I say this because about 90% of serum vitamin D is produced by sun exposure to the skin. So, the aforementioned research is really research on sun exposure. It shows that regular sun exposure leads to a profound reduction in melanoma risk. Therefore, Vitamin D levels are surrogate measurements for sun exposure in nearly every case.
Could sunlight increase health through photoproducts beyond vitamin D?
In conclusion: My new book, Embrace the Sun (coauthored by Dr. William Grant), notes that sun exposure provides more than vitamin D. It also provides other photoproducts such as nitric oxide, serotonin, endorphin, and brain-derived neurotropic factor (BDNF). All of these photoproducts are vital to human health. Could these photoproducts have a positive and protective effect against melanoma risk beyond vitamin D? And, vitamin D produced by sunlight may be superior to that given in pill form.
Finally, this research gives us one more reason to embrace the sun safely without burning. And who would have thought that safe sunlight could be one of the best prophylactics against melanoma risk?

Sunscreen may be worthless at best and dangerous at worst. I made that point in my last blog. Now, another recent scientific study corroborates this conclusion. The authors of this study probably expected a different outcome—an outcome opposite of what they found. The researchers wanted to discover which sun-protection behavior was most effective in preventing sunburn. Hence, they designed a cross-sectional investigation using a nationally representative sample of about 32,000 US adults. They interviewed each participant in person. This is especially relevant when attempting to achieve the most accurate results possible. We can conclude, therefore, that their findings regarding sunscreen use and other “sun-protective” behaviors probably have validity. Seeking shade, wearing a hat or visor, and wearing long sleeves and or pants were other sun-protective behaviors included
Sunscreen and sunburn results
In addition, they identified the subjects as sun-sensitive individuals or non-sun-sensitive individuals. Fifty-four percent of the subjects were women, and 15,992 of all individuals were considered sun-sensitive (fair skinned). Those who used only sunscreen had the highest sunburn likelihood (62.4%). The group with lowest likelihood of sunburn did not use sunscreen, but engaged in the other protective behaviors (24.3% sunburned). In addition, among 12,566 non–sun-sensitive individuals, those engaged in all 4 protective behaviors had the lowest sunburn (6.6%). The highest likelihood of sunburn was among those who only used sunscreen (26.2%). “the most surprising and counterintuitive finding was that regular sunscreen use, in the absence of other protective behaviors, was associated with the highest likelihood of sunburn.” according to Kasey Morris, who led the study, 
Other sunburn results:
Finally, you should understand this: sunscreen use associates closely with sunburning. That has been known since 2014. This is not a good product, therefore. We should protect ourselves from overexposure. But we should do it the way God (or Mother Nature, if you prefer) intended it: Cover up with clothing when you start to redden, seek shade, or go indoors for awhile. Good health depends on obtaining regular, non-burning sun exposure.
Avoid Sunscreen for another reason:
The state of Hawaii has now banned its use. This is because of the destruction of the coral reefs caused by certain ingredients in this chemical soup. In addition, the risk of melanoma skin cancer has increased exponentially since the first sunscreens were introduced. How much? By about 3,000%. And yes, you read that correctly. Do you have other questions? You should probably read the sunscreen section of my new book, Embrace the Sun, to learn more. https://www.amazon.com/Embrace-Sun-Marc-B-Sorenson/dp/069207600X

Lets talk sunscreens!
Sales of sunscreens, first of all, are a multi-billion dollar industry. And, it seems like nearly everyone believes that they are a great protection against skin cancer. Especially relevant is the fact that as sales climb higher each year, melanoma risk increases in lock step. Furthermore, sunscreen sales in 1972 were about $18 million per year. And, the total USA market in 2005 had climbed to $640 million a year. Due to inflation, that is equivalent to $320 million in 1972 dollars, an almost 18-fold increase.
What about sunscreens in cosmetics?
In addition, those figures pale by comparison with figures from 2013. The global sun care market generated $5.6 billion US dollars from its sun-protection products segment. Why? Because the sun care market includes sunscreens, many of which are ingredients in women’s cosmetics. Sales increased despite the fact that as early as 2003, it was known that sunscreens may have been partially responsible for increasing the deadliest of skin cancers, melanoma.
Another important study demonstrates that sunscreens do not help prevent melanoma. The researchers’ goal was to determine the efficacy of sunscreens in preventing melanoma. Hence, they compared melanoma rates with sales in 24 countries in Europe, during the period of 1997-1999 to 2008 and 2012. They found that higher income people had significantly higher melanoma incidence. And, increased use of sunscreens had not prevented higher income populations from being at higher risk of melanoma. Consequently, we see this equation: Higher use=higher melanoma risk! One of the reasons for this little-known relationship is most noteworthy. Up to 99% of vitamin D production is stopped by sunscreen. Hence, many of the health benefits of sun are voided.
The latest research
In conclusion, the latest research must have deflated the egos of the sunscreen manufacturers: A meta-analysis of 20 studies showed what we would expect. Both melanoma and non-melanoma skin cancers were not protected by sunscreens. It is most noteworthy that sunscreens were associated with a slight increase in risk. We could probably say from the information I’ve presented that sunscreens are worthless at best, and dangerous at worst. So, who benefits? Those who benefit from sales are pleased, while the people suffer. Therefore, it seems like the manufacturers, and the industries they support, are probably quite pleased with the worthless product.
Be careful about sunscreen ads!
So, when you next view the propaganda, be careful before you drink the Kool-Aid. And, be sure to read my new book, Embrace the Sun. It contains a full section on the chicanery that is prevalent in the sunscreen conspiracy. You will be stunned when you learn the truth.

The best disinfectant is sunlight! Therefore, those who would frighten us away from the sun would do well to study its superlative disinfectant qualities, as I have. Why use a noxious chemical as a disinfectant, when the sunlight is waiting to be used? How do we know this? First of all, the German microbiologist Robert Koch, who isolated TB bacteria in 1882, showed that sunlight had disinfectant qualities; it destroyed the bacteria. In addition, even earlier, in 1877, other researchers discovered that sugar water left in the shade became cloudy, indicative of bacterial growth. But if exposed to sunlight, it remained clear.
Disinfectant qualities of sunlight as a bactericide
Hence, radiation is a potent bactericide, or disinfectant. Dr. Kime, in his book, Sunlight Could Save Your Life, reviewed the results of research conducted between 1886 and 1909. Most noteworthy, it showed that the following bacteria were killed by ultraviolet light: Anthrax, plague, streptococci, tubercle bacillus, cholera, staphylococcus, colon bacillus and dysentery bacillus. It seems like sunlight was virtually forgotten with the advent of antibiotic drugs, but now the interest has returned.
Ultraviolet light therapy as a disinfectant for communicable diseases
While watching a newscast, I noticed the news ticker announcing, “Sunshine is the most effective anti-infection therapy.” But, is this really news? Dr. Kime cites several early studies on sunlight and infectious diseases, performed at about the same time as the advent of antibiotics. Reports in the scientific literature in the 1940s showed that sunlight killed infectious bacteria or viruses. Kime states …“a number of patients, having such various infections and diseases as blood poisoning, childbirth infections, peritonitis, viral pneumonia, mumps, and bronchial asthma were treated very successfully with ultraviolet light therapy to their blood.”, , , , , , , , , 
Do we need a natural disinfectant for superbugs?
The interest in blood irradiation for infectious diseases is now kindling new interest, due to the resistance of the “superbugs” to conventional antibiotic therapy. Especially relevant as an example of this interest is found in a scientific book chapter from 2017. It is entitled, Ultraviolet Irradiation of Blood: “The Cure That Time Forgot?” The paper reviews the history of blood irradiation in the cure for infectious diseases. The author makes the following observation: “No resistance of microorganisms to UV irradiation has been reported, and multi-antibiotic resistant strains are as susceptible as their wild-type counterparts.” Consequently, the answer to the superbug dilemma is known, but will it be used? Perhaps not. It could cost the pharmaceutical industry a fortune if a better disinfectant were found.
In addition, Dr. Kime also cited research showing that UV therapy killed flu virus outside the body and destroyed cancer-producing viruses. He reported good results in his own practice in treating fungal infections with sunlight as a disinfectant. Other early research showed that all bacteria within eight feet of low-intensity UV lights were killed in ten minutes.
Learning about disinfectant qualities of water in Mexico
A Mexican friend invited me to tour a bottled-water plant in a town called Juchipila. Interestingly, the water was exposed to UV as a disinfectant method, an inexpensive technique used in many countries. Sunlight also kills E. coli bacteria in twelve feet of seawater and in waste stabilization ponds. The Sonicare electric-toothbrush company now sells a sanitizer based on UV. The brush, after use, is placed in the UV sanitizer, because the UV light kills millions of germs in 10 minutes.
Other disinfectant history
This piece of history is also especially relevant: Nursing pioneer Florence Nightingale insisted that hospitals for wounded troops be constructed to allow free entry of sunlight. So, how many hospitals today follow her brilliant advice? Due to short memories, hospital construction returned to the “dark ages” after the advent of antibiotic drugs. Consequently, in the USA, nosocomial infections (acquired in a hospital) occur two million times yearly and claim 90,000 lives.  Meanwhile, the solution to most nosocomial infections is right outside the building, and no one will let it in! That solution is the disinfectant potential of unobstructed sunlight. At the very least, hospital rooms should be cleansed daily with UV of sufficient strength to kill surrounding bacteria. Probably, hospital profits would improve since they are businesses, after all.
Cost savings with the natural disinfectant: sunlight.
The University of Pennsylvania’s Center for Health Transformation states: “Nosocomial infections create terrific problems by prolonging hospital stays, occupying scarce bed-days, requiring a greater number of diagnoses, more medication, and a greater burden on doctors and nurses.” They estimate, “If a 300-bed hospital with 10,000 admissions yearly had a 5 percent annual infection rate (500 infections) with costs of $600 to $50,000 depending on the type of infection, the total costs for these infections could be as high as $7.6 million.” So, multiply that by the number of hospitals. Imagine the savings if they let the light in! The patients in such rooms would also be happier and have a more positive outlook.
It makes sense to return to a sanitation method used successfully for millennia, especially given the reality of superbugs. The antibiotic drug revolution destroyed the successful and promising use of UV lamps and sun exposure as antiseptic, disinfectant, pro-immunity treatments. Antibiotics are failing. Therefore, the interest in UV must be renewed. We walk in darkness (or under artificial light) due to our obsession with the pursuit of new antibiotics, Hence, we fail to see the brilliant source of healing that awaits us outside.
The old-time disinfectant
Serendipitously, I happened on an article called Natural Alternatives to Bleach for Disinfecting. It discussed pros and cons of such disinfectants as bleach, vinegar, hydrogen peroxide and yes, sunlight. In conclusion, the article stated that bleach could be dangerous. It could cause irritation to the eyes, mouth, lungs and skin, and could result in the release of toxic fumes. Therefore, this is not a good disinfectant!
The authors suggested three alternatives: vinegar, hydrogen peroxide, and sunlight, with sunlight being the safest disinfectant. The article states; “In fact, scientists have found that exposing a bottle of water to sun for 6 hours is an economical way to provide developing countries with safe drinking water. The disinfecting properties of sun can also be useful around the house. If you have an object you can move outside, the sun’s rays can help disinfect it. A stained piece of white laundry can be effectively brightened and disinfected by spraying the stain with lemon juice or vinegar, then hanging it in the sun.”
In addition, the authors also mentioned that exposing the armpits to the sun would kill odor-causing bacteria. There is little I (Sorenson) enjoy more than sunbathing with my hands behind my head and my armpits exposed to the sun. Lots of vitamin D, nitric oxide and endorphins produced, and therefore, I am more popular with my friends—without using deodorants!
Sunlight is a disinfectant for smelly socks!
Furthermore, research has shown that sunlight may be a good disinfectant for your socks and feet. Scientists tested socks contaminated with the fungus causing tinea pedis (“athlete’s foot”), a chronic skin disease. The objective of the research was “to evaluate the effectivity of sun exposure in reducing fungal contamination in used clothing.” Fifty-two socks, proven by fungal culture to be contaminated by patients with tinea pedis, were studied. The the researchers divided the samples into two groups: Group A underwent sun exposure for 3 consecutive days and Group B remained indoors. At the end of each day fungal cultures of the samples were performed. As a result, the researchers reported that elimination of the fungal cultures was significant in the sun-exposure group, but not the indoor group. Sunlight is a great disinfectant, indeed!
Finally, I remember my childhood. I won’t forget how fresh the clothing (including the socks) smelled after my mother had laundered and hung it outside in full sunshine to dry. I expect that fungi or bacteria were eliminated, along with odor, which would have occurred in a dark place.
Let’s give the sun its proper place in our world. It may save our lives.

Stunning Breast Cancer research shows that the highest vitamin D levels associate with an 80% reduction in risk.
Is the breast cancer pandemic due to vitamin D deficiency?
First of all, as pointed out by the authors, numerous studies have shown an association between higher vitamin D level and breast cancer. But, other studies had not taken into consideration serum levels of vitamin D above 40 ng/ml. Why? Because that level had been considered the highest level needed for good health. Nevertheless, this study showed differences in breast cancer risk when comparing all serum vitamin D levels, and that made all the difference in the results. The research included 5,038 women.
A dose-response association between vitamin D levels and breast cancer
The most noteworthy finding can be summed up in the study conclusions: “Higher 25(OH)D concentrations were associated with a dose-response decrease in breast cancer risk with concentrations ≥60 ng/ml being most protective.” In other words, the higher the vitamin D levels, the greater was the protection.
This fact is especially relevant: serum vitamin D levels in 90% of the population are effected by sun exposure. Hence, sun exposure may be the operative factor in the comparisons. Sun exposure causes the body to produce nitric oxide, serotonin, endorphin and brain-derived neurotropic factor (BDNF). Most noteworthy is that all of these photoproducts are vital to human health.
Is something besides vitamin D at work in preventing breast cancer?
Therefore, it could be that these additional photoproducts added power to the vitamin D produced by the sun. Could the “holistic” sun be more important than vitamin D alone? Of course it is! Another study, little known, may hold the answer. An investigation from Iran, on the association between breast-cancer risk and vitamin D, showed that low vitamin D predicted only a slightly increased risk of the cancer. However, among women who totally covered themselves and thereby had no sun exposure, there was a 10-fold increase in the risk of the disease. In other words, there was a 1,000% increase in breast cancer risk due to sun deficiency.
Finally, consider this: With the holistic sun, we get the entire package, not just vitamin D. Embrace the Sun, and don’t burn.

First of all, to think is to prevent poor test scores, win at business and otherwise be successful. And, if I think and remember clearly, I also prevent mental disabilities such as Alzheimer’s. Consequently, there are innumerable pills on the market that purportedly increase the ability to think. But you may need only one pill to improve your cognitive ability: the sunshine pill. It is most noteworthy that I’m not talking about vitamin D. Therefore, the sunshine pill is not really a pill at all. Rather, it is exposure to the UV light of sunlight itself, which helps prevent myriad diseases. Maybe we should call it the “magnificent non-pill.”
How does the sunshine pill help us to think?
Recent research shows that exposure to sunlight causes a cascade of chemical reactions that help us to think. Especially relevant is the fact that exposure to UV elevates a natural chemical known as blood urocanic acid (UCA). This chemical then crosses the blood-brain barrier. This chemical is then converted by a metabolic process to glutamate, and consequently, nerve synapses in the brain are enhanced. As a result, there were improvements in both physical learning (motor learning) and object recognition memory, which is an ability to think.
Is there more research indicating that sun exposure enhances the ability to think?
In addition, the ability to think has been shown in many research studies to improve with sunlight. Most noteworthy is a 2013 article, published in the journal Neurology. It reveals that among people with high sun exposure, the risk of Alzheimer’s disease (AD) is profoundly decreased. Therefore, they are able to think more clearly than those who receive low sun exposure.
Finally, research published in the journal Endocrinology, sums up the effects of the sun on the brain and body: It is entitled, “How ultraviolet light touches the brain and endocrine system through skin, and why.” The authors begin their abstract by stating that “the skin is a self-regulating protective barrier organ that is empowered with sensory and computing capabilities to counteract the environmental stressors to maintain/restore disrupted cutaneous homeostasis.” In other words, the skin has the ability to take on what life deals it, and maintain its equilibrium and balance. In addition, the skin communicates bidirectionally with the central nervous, endocrine and immune systems. Thus, it helps to maintain balance for all body systems, including the ability to think.
Safely soak up the non-burning sunlight and enhance your intelligence!

May is Melanoma Awareness Month, Therefore, we will discuss some truths to be aware of:
- First of all, seventy-five percent of these cancers occur on areas of the body that are seldom or never exposed to sunlight. For example, research has shown that melanomas in women occur primarily on the upper legs, and in men more frequently on the back—areas of little sun exposure.
- Most noteworthy, in the U.S., sun exposure has decreased by about 90% since 1935. In the same time, melanoma incidence has increased by 3,000%!   
Dr. Diane Godar furnishes this exceptionally important melanoma information:
- The same as in the US, while sun exposure in Europe has profoundly decreased, there has been a spectacular increase in the disease.
- Men who work outdoors have about half the risk as men who work indoors. Hence, sun exposure could not me the cause.
- in addition, outdoor workers, while receiving 3-9 times the sun exposure as indoor workers, have had no increase in melanoma since before 1940, whereas the incidence in indoor workers has increased steadily and exponentially.
- Especially relevant is that sunscreen invention, along with its steadily increasing use, has not reduced the risk of melanoma. Rather, the disease has increased as sunscreen use has increased.
- Increasing melanoma incidence significantly correlates with decreasing personal annual sunlight exposure.
- Also, outdoor workers get many sunburns but still have dramatically lower risk of contracting the disease.
So, since melanoma increases as sun exposure decreases, should we continue to blame the sun?
Here are more facts you should know about the causes of melanoma:
- First of all, people in the highest quintile (fifth) of alcohol consumption have a 65% increase in risk.
- Weekly meat consumption increases the risk of melanoma by 84% and daily fruit consumption reduces the risk by nearly 50%.
- Furthermore, those with the highest levels of blood PCBs have 7-times the risk compared to those with the lowest levels.
- Recent use of Viagra is associated with an 84% increase in risk, and long-term use of the drug is associated with a 92% risk increase.
- Finally, there is a positive association between melanoma and obesity.
Furthermore, Dr. Adele Green found that the strongest risk factor for both limb and trunk melanoma was moles. The presence of more than 10 moles on the arm predicted a 42-times increased risk.
Therefore, please stop blaming the sun. Safely embrace the non-burning sun and reduce your risk of melanoma.
