LAS VEGAS—I honestly hope you're not reading this story just before you get ready for bed. Because honestly, the light from the computer screen is likely to disrupt your sleep patterns. In fact, many of the lights in your home are probably confusing the heck out of your poor, tired brain.
This is not the ramblings of a madman—well, not any more than usual, really—but actual science, and it's the driving force behind a line of light bulbs developed by Lighting Science.
As Robert Soler, Lighting Science's director of lighting research explained to me on the CES show floor, photoreceptors in the eye send signals to your brain to regulate your internal clock. Specifically, blue light signals your brain that it's daytime, and that it needs to be alert.
Most of the light bulbs we use mimic that blue light, and that's a problem around bed time. The clock on the wall may say that it's time to turn in, but the clock inside your head is still getting pelted with blue light from the lamps in your home. And that can make it difficult to fall asleep or have a very restful night.
