THE LAST HOURS OF ANCIENT SUNLIGHT PDF SKIN CANCER INDIRECTLY

For the ancient Greeks and Romans, Apollo was the god of medicine and healing as well as of sun and lightвЂ”but Apollo could bring sickness as well as cure. Each day, ApolloвЂ™s fiery chariot makes its way across the sky, bringing life-giving light to the planet. As humankind evolved from hunter-gatherers, weve learned how to use more and more sunlight, which is stored in the form of fossil fuel. Sunlight makes life on earth possible.

The Last Hours Of Ancient Sunlight Pdf Skin Cancer Indirectly

UVA radiation (95вЂ“97% of the UVR that reaches EarthвЂ™s surface) penetrates deeply into the skin, where it can contribute to skin cancer indirectly via generation of DNA-damaging molecules such as hydroxyl and oxygen radicals. Most public health messages of the past century have focused on the hazards of too much sun exposure.

Both forms can damage collagen fibers, destroy vitamin A in skin, accelerate aging of the skin, and increase the risk of skin cancers.

As for what constitutes вЂњexcessiveвЂќ UVR exposure, there is no one-size-fits-all answer, says Lucas: вЂњвЂExcessiveвЂ™ really means inappropriately high for your skin type under a particular level of ambient UVR.вЂќUnlike other essential vitamins, which must be obtained from food, vitamin D can be synthesized in the skin through a photosynthetic reaction triggered by exposure to UVB radiation. At least 1,000 different genes governing virtually every tissue in the body are now thought to be regulated by 1,25-dihydroxyvitamin D 3 (1,25D), the active form of the vitamin, including several involved in calcium metabolism and neuromuscular and immune system functioning.Although most of the health-promoting benefits of sun exposure are thought to occur through vitamin D photosynthesis, there may be other health benefits that have gone largely overlooked in the debate over how much sun is needed for good health. This burden subsumes major disorders of the musculoskeletal system and possibly an increased risk of various autoimmune diseases and life-threatening cancers.The best-known benefit of sunlight is its ability to boost the bodyвЂ™s vitamin D supply most cases of vitamin D deficiency are due to lack of outdoor sun exposure. Therefore, when measuring by DALYs, these diseases incur a relatively low disease burden despite their high prevalence.In contrast, the same WHO report noted that a markedly larger annual disease burden of 3.3 billion DALYs worldwide might result from very low levels of UVR exposure. Coauthor Robyn Lucas, an epidemiologist at the National Centre for Epidemiology and Population Health in Canberra, Australia, explains that many diseases linked to excessive UVR exposure tend to be relatively benignвЂ”apart from malignant melanomaвЂ”and occur in older age groups, due mainly to the long lag between exposure and manifestation, the requirement of cumulative exposures, or both. DALYs measure how much a personвЂ™s expectancy of healthy life is reduced by premature death or disability caused by disease.

The first humans evolved in equatorial Africa, where the direct angle of sunlight delivers very strong UVR most of the year. вЂњLow vitamin D levels will precipitate and exacerbate osteoporosis in both men and women and cause the painful bone disease osteomalacia,вЂќ says Holick.In the 2002 book Bone Loss and Osteoporosis in Past Populations: An Anthropological Perspective, Reinhold Vieth, a nutrition professor at the University of Toronto, writes that early primates probably acquired their relatively high vitamin D requirements from frequent grooming and ingestion of oils rich in vitamin D precursors that were secreted by their skin onto their fur. In August 2007, the Agency for Health Care Policy and Research published Effectiveness and Safety of Vitamin D in Relation to Bone Health, a systematic review of 167 studies that found вЂњfair evidenceвЂќ of an association between circulating 25(OH)D concentrations and either increased bone-mineral density or reduced falls in older people (a result of strengthened muscles as well as strengthened bones). More recently, there has been a growing appreciation for vitamin DвЂ™s impact on bone health in adults. In children, this causes rickets, a disease characterized by growth retardation and various skeletal deformities, including the hallmark bowed legs.

Phototherapy quickly emerged as a popular medical treatment not only for TB, but also for rheumatic disorders, diabetes, gout, chronic ulcers, and wounds. The suntan became valued in the Western world as a new status symbol that signified both health and wealth, as only the affluent could afford to vacation by the sea and play outdoor sports. Nevertheless, a meta-analysis published in the February 2008 International Journal of Epidemiology found that high vitamin D levels reduce the risk of active TB (i.e., TB showing clinical symptoms) by 32%.Almost overnight, as awareness of the sunвЂ™s power against rickets and TB spread, attitudes toward sun exposure underwent a radical shift. Gilchrest of Boston University School of Medicine says that, whereas sun exposure was shown to improve cutaneous TB, sanatorium patients with pulmonary TB likely responded as much or more to rest and good nutrition than to UVR.
