In his latest book (1), physics professor Dr. Richard L. Hansler describes the research of 10 leading scientists that underlies his belief that electric lighting is an important environmental cause of the rapid rise in the incidence of breast and prostate cancer. Primitive societies without electric lighting have a much lower incidence of these cancers according to World Health Organization statistics.. In 1996, Dr. Richard Stevens (University of Connecticut) proposed the “melatonin hypothesis” (2) that the reduction in the time that melatonin is present in the blood as a result of exposure to light, is responsible for the increased incidence of cancer. This hypothesis is supported by the large disparity in the cancer rate in advanced societies compared to that in primitive countries without electric lighting.
Dr. Hansler spent more than 42 years as a research scientist for General Electric developing better and brighter light bulbs. It wasn’t until after his retirement from GE and his move to John Carroll University that he became interested in the health effects of lighting. The health benefits of vitamin D are well known. It is produced when the skin is exposed to ultraviolet light. What was new to him, and most disturbing, is that using ordinary light at night has serious detrimental effects on health as mentioned above. He feels a moral obligation to do something about this situation.
At the turn of the century, two independent research groups (3) (4) discovered that it is primarily the blue rays in ordinary light that are responsible for the suppression of the hormone melatonin. When Dr. Hansler learned this, he realized that there is a simple solution to the problem. All that is needed is to make light bulbs that filter out the damaging blue rays. He, along with Dr. Edward Carome and Vilnis Kubulins at John Carroll University set to work developing such light bulbs. They also developed eyeglasses that block the harmful blue rays. The glasses are worn for 1 to 3 hours before bedtime and then removed.They formed a spin-off company, Photonic Developments LLC that operates a website http://www.lowbluelights.com that makes these products available. Filters for TV and computer screens are also available. His goal is to cut the rate of breast cancer in half, to that of American woman who are totally blind.
He found to his dismay that few people were all that interested in preventing cancer. This then is the purpose of the “Heroes” book. It’s a way of convincing women by examining the work of these 10 scientists, that they can reduce their risk by simply switching to light bulbs that don’t produce the damaging blue rays. As an alternative, they can avoid blue light in the hours before bedtime by wearing glasses that block blue light.
There are very significant side effects of maximizing melatonin. It helps people fall asleep more easily and sleep more soundly (5). This is the primary reason why thousands of people have purchased the special light bulbs and glasses according to sales figures from Photonic Developments LLC. The glasses are sold with a guarantee that their money will be returned if they don’t sleep better. A second significant side effect is that using the glasses helps people with bipolar disorder stabilize their mood (6). Many of the other beneficial effects of melatonin are described in Dr. Russel J. Reiter’s book “Melatonin”.
“Heroes of cancer prevention research” is available from the website or from Amazon as a paperback or as a Kindle book. As Dr. Hansler concludes in his book, “Without action, knowledge is of little value”.
