Cryptochromes and the “Sixth Sense”
In recent years, scientists have discovered a unique class of proteins, dubbed cryptochromes, which may function to detect subtle electromagnetic fields in creatures ranging from amphibians and birds, to humans. The significance of this obscure fact is that cryptochromes may be the mechanism whereby some people are sensitive to supposedly undetectable electromagnetic energy fields.
The implications for human health are a bit disturbing. Some people believe that radio-frequency wavelength energy from sources like cell phones, cell phones towers and cordless phone bases may subtly affect human health. There is limited, emerging evidence that exposure to these fields discourages the production of melatonin, an important antioxidant hormone that is secreted by the pineal gland (the “third eye”) in response to complete darkness at night. Both artificial light, (and, theoretically) unnatural EMF fields can interfere with the release of melatonin.
And disturbances in melatonin production and release have been linked to an increased risk of cancer, insomnia, and other ailments. Many scientists now believe that EMF, like artificial blue light, disturbs the natural 24-hour cycle of melatonin, which is intimately linked to the sleep/wake cycle. The “melatonin hypothesis” remains an open question, however. My personal feeling is this: If you must use cordless phones in the home, consider erring on the side of caution. Remove cordless phones and/or their base stations from the bedroom to limit unnecessary exposure to the EMF fields these devices generate.
