What you didn’t know about skin cancer could kill you

We must understand that if we were destined to spend most of our lives underground and hidden from the outside, appearing socially only at night, then nature would have arranged for us to be born rodents and not humans.

Fluorescent lighting may save you some money, but it comes at a greater cost to your health. UV emissions from overhead fixtures have been linked to an increased risk of melanoma skin cancer from american journal of epidemiology.

Researcher Dr. Helen Shaw and her team conducted a study of melanoma at the London School of Hygiene and Tropical Medicine and at the Sydney Melanoma Clinic at 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 showed that those who spent the most time in natural sunlight had by far the lowest risk of developing skin cancer. In stark contrast to those who live or work outdoors, office workers who were exposed to artificial light for most of their work hours had the highest risk of developing melanomas. He also discovered that fluorescent lights cause mutations in cultured animal cells.

Dr Shaw’s research led to the conclusion that in both Australia and Great Britain, melanoma rates were high among professional and office workers and low among people who worked outdoors. In other words, Aussies and Brits (and the rest of us) would be better off spending more time outdoors, where there’s plenty of UV light! Similar controlled studies were conducted at the New York University School of Medicine, which confirmed and corroborated the results of Dr. Shaw’s research.

Fluorescent lighting is also known to cause headaches, eye problems such as night blindness, fatigue, concentration difficulties, and irritability. An increase in the brightness of fluorescent lighting has also been observed to lead to increased stress levels by raising levels of the hormone cortisol.

In a study conducted among US Navy personnel between 1974 and 1984, researchers found a higher incidence of skin cancer among sailors who had indoor jobs than those who worked outdoors. Those who work both indoors and outdoors showed the greatest protection, with a rate 24 percent below the U.S. national average. Since none of the sailors spend all day outdoors, it could not be determined if being outdoors all day would offer the greatest degree of protection.

It’s interesting to note that some of the hottest places in the US, like Phoenix, Arizona, have the highest rates of skin cancer, but not because they expose their skin to the sun. Researchers are easily tempted to link the alarming rates of skin cancer to the sun and the fact that these areas are some of the hottest and sunniest in the country. But hastily making that link without careful observation, without exhausting all possible parameters, is foolish and irrational.

Extreme heat for 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, due to insufficient exposure, not the other way around. There are now hundreds of scientific studies showing 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 sell you sunscreen and treat cancer for a living. It is a multi-billion dollar business that is too big to fail.
