Safe light bulbs (also known as cancer safe light bulbs) have been developed and are being marketed in response to scientific studies that have determined that performing ordinary functions (reading, sewing, cooking, etc.) under artificial light from ordinary (white) light bulbs decreased the body’s secretion of melatonin. Melatonin, a hormone produced by the pineal gland, is known to effectively fight cancer and therefore reduces the growth of cancerous tumors.
The pineal gland produces melatonin most effectively when the brain perceives total darkness. It’s a well-known fact that people who are blind, and even people who sleep extended hours (9 or more), produce more melatonin and, as a result, have a lower cancer rate. Scientists set out to determine what it was about artificial light that reduced melatonin production and discovered that the blue rays emitted from ordinary light bulbs were the culprits. Safe light bulbs, first developed by physicists at John Carroll University, remove the blue rays and, as a result, do not have a negative effect on the pineal gland's production of melatonin. Safe light bulbs produce yellow light -- that is the visual effect of removing the blue rays emitted by ordinary light bulbs; for the pineal gland, blocking blue rays is the same as darkness. It is recommended that people with cancer in remission, or with a high risk for cancer due to a strong family history, either switch to using safe light bulbs in the evenings or wear yellow-tinted eye glasses to block the blue rays from ordinary light bulbs. |
