Light, Health & the Electromagnetic Spectrum >>>
“The human eye sees less than 1 per cent of the total electromagnetic spectrum. [Much has been learned] … about the mysterious light sources at either end of the visible spectrum—the ultraviolet, infrared, and so-called background radiation … [and] evidence now [indicates] … they exert a profound influence on the physical and mental health of animals, plants and [humans].”

“Light energy has a profound effect on everything. Imagine if you went into your garden and gave one plant more light than the other—you know there would be a visible difference in their growth. If you took different colored glass and put it on top of each plant so that the color that each plant got was different by eliminating certain colors from the rainbow spectrum, again you notice some of the plants would grow taller, some would never develop fully, some would develop fruit but the fruit would fall off.”
“The same thing happens in the human body but we’ve really never looked at that way. This is so crucial right now, today, because up to 1900, 90% of us made our living working outdoors. We were in natural full spectrum daylight without visual confinement. Our eyes could look off into the horizon. Now more than 90% of us, since 1990, work indoors with artificial lighting that is grossly different from nature’s own daylight, with artificial controlled and conditioned air … and with a huge amount of visual confinement. We sit in front of books, computers, cubicles, small rooms, low ceilings, windowless classrooms…”
