LED Lighting Fights Continue After AMA Warnings

It seems like high-intensity LED streetlights have taken over cities and towns everywhere you go. Municipal governments like them because they’re bright and cheaper to run. But, they have a downside, and red flags are going up on these blue light forms of illumination, most recently reported in The Washington Post.

The American Medical Association (AMA) has already issued warnings that these lights not only have a negative effect on drivers, but can severely disrupt your sleep. The AMA says these blue-rich LED streetlights operate at a wavelength that adversely suppresses melatonin at night, with “five times greater impact” on circadian sleep rhythms than conventional street lamps.

Melatonin is a hormone your body produces at night, and one of its primary roles is to help you sleep. But did you know that melatonin also may help protect against heart disease, diabetes, Alzheimer's and migraine headaches? Or that it may help with weight control and strengthening your immune system? It even appears to play a role in cancer prevention and as a powerful antioxidant that helps “cool down” excess inflammation.

Because artificial lighting disrupts your melatonin production, many Americans are looking for ways to reduce their exposure to it. One way is to use blue light-blocking glasses. The benefits of blue-blocking glasses are immense and varied, including helping to prevent damage to the DHA essential fat in your retinal pigmented epithelium which is responsible for converting sunlight into vital DC electric current your body needs.
