Why blue light's special
Light makes it easier to read a book and find your way around, but it's much more important than that. By affecting hormones such as melatonin and nutrients such as vitamin D, it also has a big impact on the body, mind, and behavior.
"For thousands upon thousands of generations we were hunter-gatherers, out in the daylight and exposed to that blue sky," says neurologist George Brainard,Firms are aware of the economic pressures that are memo-pad placed on consumers nowadays and recognise there is an importance in obtaining value for money.Remember, hiphonei9 themselves aren’t new; they have been available to consumers for about four years as bulbs that can be screwed into existing light sockets Ph.D., the director of the Light Research Program at Thomas Jefferson University, in Philadelphia. "Since about a century ago, when Edison and others developed electricIn order to perform your work more accurately in the kitchen, you need to have adequate illumination compact fluorescent light bulb or task light in the key work areas. These work areas include the counter, range, sink, island and table. lighting,It's also important to remember that you don't guccijean always have to stick with the overall style of the room. we've become [a] predominantly indoor-dwelling species. We've been removed from our natural stimulus."
Studies have shown that blue light improves alertness and mental performance, but researchers haven't fully understood what makes it different from red, green, or white light.

Now they're getting some answers. In the new study, 17 healthy volunteers were placed in a dimly lit lab, hooked up to a brain-scanning machine, and exposed to 40-second bursts of alternating blue and green light with periods of darkness in between. As the lights came on and off, the researchers played snippets of recorded speech that sounded angry or neutral, as a way of provoking an emotional reaction.
When they analyzed the brain scNexxus Lighting, Inc. recently announced it received the ENERGY STAR label, and is included in the ENERGY STAR Qualified necklabel list, for its Array branded R30 LED light bulb.ans, the researchers discovered that blue light, more so than the green light, seemed to stimulate and strengthen connections between areas of the brain involved in processing emotion and language.
"We found that if you have an emotional stimulus processed by the brain, it is quite impressively affected by light and wavelength composition," says the lead researcher, Gilles Vandewalle, a brain expert at the University of Liege, in Belgium.
Emotion and mood are related, of course, but Vandewalle and his colleagues aren't certain that the emotional changes they saw in the study would translate into lasting effects on mood. (The researchers did not ask the participants how they felt.)
However, they suspect that the brain response associated with blue light may enable people to adapt to emotional challenges more easily, which could help regulate mood over the long term.
