We must understand that if we were meant to spend the greater part of our lives underground and hidden from the outdoors, only appearing socially at night, then nature would have arranged for us to be born rodents and not humans.
Fluorescent lighting may save some money, but it takes a bigger toll on your health. The UV emissions from ceiling fixtures have been linked to a higher risk of melanoma skin cancer by the American Journal of Epidemiology.
Researcher Dr. Helen Shaw and her team conducted a melanoma study at the London School of Hygiene and Tropical Medicine, and at the Sydney Melanoma Clinic in Sydney Hospital. They found that office workers had twice the incidence of the deadly cancer as people who worked outdoors. The results of the study were published in 1982 by the British medical journal Lancet. Dr. Shaw proved that those who spent most of their time exposed to natural sunlight had by far the lowest risk of developing skin cancer. In sharp contrast to those living or working outdoors, office workers, who were exposed to artificial light during most of their working hours had the highest risk of developing melanomas. She also discovered that fluorescent lights cause mutations in cultures of animal cells.
Dr. Shaw's research led to the conclusion that both in Australia and Great Britain, melanoma rates were high among professional and office workers and low in people working outdoors. In other words, the Australians and British (and the rest of us) would be better off spending more time outside where there is plenty of UV light! Similar controlled studies were conducted at the New York University School of Medicine, which confirmed and substantiated Dr. Shaw's research results.
Fluorescent lighting has also been known to cause headaches, eye problems such as night blindness, fatigue, concentration difficulties and irritability. It has also been observed that an increase in the brightness of fluorescent light leads to higher stress levels by raising cortisol hormone levels.
In a study conducted on US Navy personnel between 1974 and 1984, researchers found a higher incidence of skin cancers among sailors who had indoor jobs than those working outside. Those working both indoors and outdoors showed the most protection, with a rate 24 percent below the U.S. national average. Since none of the sailors spend their entire day outside, it could not be determined whether being outside all day would offer the highest degree of protection.
It is interesting to note that some of the hottest places in the U.S., such as Phoenix, Arizona, have the highest rates of skin cancers, but not because they expose their skin to the sun. Researchers are readily tempted to relate the alarming skin cancer rates to the sun and the fact that these areas are some of the hottest and sunniest in the country. But to hastily make that link without careful observation, without exhausting all possible parameters is foolish and irrational.
The extreme heat throughout much of the year keeps most people indoors during the day. As a result, although there is plenty of sunlight, people avoid it and develop health problems including cancers from underexposure rather than the other way round. There are now hundreds of scientific studies to show that vitamin D deficiency is one of the leading causes of cancer, including malignant melanomas.
However, don't expect to hear about these studies from those who make a living of selling you sunscreens and treating cancers. It's a trillion dollar business that's too big to fail.Article Source: http://EzineArticles.com/6435656
