Cancer Safe Light Bulbs Announced: Ordinary Light Bulbs 'Stimulate the Growth of Human Breast Tumors' (Gov. Report)

University Heights, OH (PRWEB) December 29, 2005 -- The nighttime use of artificial light stimulates human breast tumors according to a Dec. 19, 2005 press release from the National Institute for Environmental Health Sciences.
This is the result of melatonin suppression. University scientists have invented light bulbs that do not suppress melatonin.
A press release from the National Institute for Environmental Health Sciences states:
“Results from a new study in laboratory mice show that nighttime exposure to artificial light stimulated the growth of human breast tumors by suppressing the levels of a key hormone called melatonin. The study also showed that extended periods of nighttime darkness greatly slowed the growth of these tumors.” 12/19/2005
Light is known to suppress the secretion of melatonin, a powerful antioxidant and cancer fighter. It is also known it is the blue rays in ordinary light that suppress melatonin.
Physicists at John Carroll University have invented light bulbs that remove the blue rays. Light without the blue rays looks yellow. They recommend that people at high risk for cancer switch to using the yellow lights in the evening to get melatonin flowing.
Scientists at Toronto University have proven that wearing goggles with filters that block the blue light allow people to make melatonin. Putting on yellow glasses in the evening is thus another option for getting melatonin to be present for a longer time to fight cancer.
Blocking blue light is the same as darkness (“Virtual darkness”) for the pineal gland that makes melatonin.
Studies show that blind people and people who consistently sleep unusually long (9 hours or more) have a significantly lower cancer rate. They also produce melatonin for a longer time. This is consistent with the idea that avoiding white (contains blue) light during the evening will reduce the risk of cancer.
Studies with turkey hens with ovarian cancer showed that doubling the time they were held in darkness each day from 8 hours to 16 hours resulted in decreased tumor growth and complete remission in some birds. There is a huge difference between turkeys and humans so caution is necessary in drawing any conclusions. It is suggestive however, that long periods of real darkness combined with “virtual darkness” might be useful for patients with cancer. Melatonin has been shown to be beneficial in combination with some forms of chemotherapy and radiation therapy.
Yellow light bulbs, filters for TV and computers screens and blue-blocking eyeglasses are all available at www.lowbluelights.com.
