Melatonin Fights Liver Cancer According to New Studies

June 27, 2013

Maximizing melatonin production in humans is possible by blocking blue light for a few hours before bedtime by wearing amber eyeglasses according to Richard L. Hansler PhD of Photonic Developments LLC. This may be of benefit in avoiding or treating liver cancer.

University Heights, OH (PRWEB) June 27, 2013

A new paper from Thailand (1) shows that melatonin improves the outcome when liver cancer is induced in hamsters. A new study (2) from Spain found that melatonin blocked the processes that control the development of new blood vessels needed for the liver cancer to grow. These studies help explain the 1999 study (3) from France that found that exposing rats to continuous light greatly increased the fraction of rats who developed liver cancer when given a carcinogen compared to those raised in normal 12 hours light 12 hous dark. Continuous light prevents the production of melatonin. This also may explain why the odds are about double of getting colon cancer, prostate cancer, rectal cancer, and pancreatic cancer for men working night shift according to a new paper (4) from Canada. Liver cancer was not included in this study. Working nights reduces the production of melatonin due to exposure to light.

In 2005, physicists at John Carroll University developed light bulbs that don’t produce blue light and amber eyeglasses that eliminate blue light. In 2001, it had been shown that it is primarily the blue rays in ordinary white light that suppress the production of melatonin–the sleep promoting, cancer fighting hormone. These products are available at http://www.lowbluelights.com along with filters for TV and computer screens including iPads and iPhones. Thousands of people have bought these products with a guarantee of money back if they don’t help. About 90% find they help them sleep. Possibly reducing the risk of cancer comes as a free bonus.
