“…There is also an interesting paper reporting an inverse correlation of dental caries with respect to hours of sunlight in the United States. In a study of male adolescents aged 12-14 years living in rural or semirural regions, the findings were: 4.86 caries/adolescent for \2200 h of sunshine/year; 3.74 for 2200-2600 h; 3.25 for 2600-3000 h; and 2.91 for [3000 h [107].…”

Originally recognized for reducing the risk of rickets, the benefits of vitamin D were extended in the past three decades, to protection against many non-calcemic diseases. The primary source of vitamin D is production by solar ultraviolet B (UVB) irradiance. In this paper, evidence is reviewed that vitamin D reduces the risk of about 17 types of cancer; bacterial infections for diseases such as dental caries, periodontitis, septicemia, and tuberculosis; viral infections such as respiratory infections and EpsteinBarr virus; autoimmune diseases such as asthma and multiple sclerosis; cardiovascular diseases such as coronary heart disease, diabetes, and stroke; and dementia. Several studies have also reported longer life expectancy with higher vitamin D supplement or serum 25-hydroxyvitamin D levels.

“…An ecologic study in the USA in the 1930s found that the number of dental caries among adolescent white males living in the west, where there is >3000 h of sunlight/year, was half that of those living in the northeast, where there is <2200 h of sunlight/year [471]. Bacteria are involved in the development of dental caries, and are sensitive to cathelicidin produced by vitamin D. Chronic adult periodontitis is a bacterially induced chronic inflammatory disease that destroys the connective tissue and bone that support teeth and for which the mechanisms involved are still being worked out [472].…”

The Sun has played a major role in the development of life on Earth. In Western culture, people are warned against Sun exposure because of its adverse effects: erythema, photoimmunosuppression, photoageing, photocarcinogenesis, cataracts and photokeratitis. However, Sun exposure is also beneficial, since moderate doses give beneficial physiological effects: vitamin D synthesis, reduction of blood pressure and mental health. Shortage of Sun exposure may be even more dangerous to human health than excessive exposure. Avoiding Sun exposure leads to vitamin D deficiency which is associated not only with rickets and osteomalacia, but also with increased risk of cardiovascular disease, multiple sclerosis, rheumatoid arthritis, diabetes, influenza, many types of cancer and adverse pregnancy outcomes. Solar radiation induces nitric oxide release in tissue and immediate pigment darkening which certainly play important roles, although these are still unknown. Action spectra relevant for health are described. We will also review what is known about spectral and intensity variations of terrestrial solar radiation as well as its penetration through the atmosphere and into human skin and tissue.

Multiple Sclerosis and Prostate Cancer: What Do Their Similar Geographies Suggest?

Mortality rates from multiple sclerosis show a well-known north-south gradient, both within the United States and internationally. Mortality rates from prostate cancer show a similar gradient and are significantly correlated with multiple sclerosis (MS) mortality and MS prevalence. This finding adds prostate cancer to the set of diseases whose geographic distributions are significantly correlated with MS and whose members include colon cancer, dental caries, and Parkinson''s disease. Review of the literature indicates that these clinically dissimilar diseases may share an aberration in vitamin (hormone) D. Recent evidence demonstrating a multi-faceted role for vitamin D in immunoregulation suggests that a vitamin D aberration may also contribute to the etiology of MS. A vitamin D hypothesis can illuminate several unexplained features of the epidemiology of MS and suggests opportunities for epidemiologic, laboratory, and clinical investigation.
