These days, we have a tremendous amount on our plates. We’re constantly looking for an energy boost, something that can give us an edge and extra motivation to get through the day. While coffee, cigarettes, energy drinks and other remedies have received mixed reviews, the most natural of solutions could be the secret to workplace productivity and a sense of well-being.
Many people aren’t aware that there are tangible health benefits provided to us from spending time in the sun. “Being out in the sun boosts our mood, improves sleep, and promotes vitamin D production,” says James Spencer, associate clinical professor of dermatology at Mt. Sinai School of Medicine in New York. “There’s no controversy about that.” The controversy is determining what part of the sun’s light is most beneficial to us, and what part is harmful.
Researchers at the Fraunhofer Institute for Silicate Research in Wurzburg, Germany think they have found the most beneficial part of the sun; the blue light region of the UV spectrum. They’ve developed a special thin, long-lasting and barely noticeable glass coating that lets light with wavelengths between 450-500 nanometers through, i.e. blue light.
Blue light governs our hormonal balance and stimulates our brains. A lack of blue light triggers a response in our bodies that leads to higher melatonin levels, which has often been associated with sleep issues, concentration issues and depression. The patent-pending invention is being called VITAL feel-good glass, and it’s being produced by a company called UNIGLAS.
“Nobody’s ever made glass like this before. It makes you feel as if the window is permanently open,” says Walter Galubitt, an engineer at Fraunhofer.
The less useful, brighter light on the spectrum isn’t allowed through, so the invention has shown few drawbacks. Expect to see this technology trickle into our lives very soon.
These windows would be a welcome addition to automobiles, office buildings and arenas everywhere. Even if you’re not currently sitting by a window, it’s hard not to feel great about an innovation like this.
