Human Centric Lighting continues to be in the forefront of LED advancement technology in providing users with well-being in office spaces. This article shows the detriment to our sleep patterns and possibly health by using phone, tablet and computer screens.
There’s a lot of evidence that blue light, emitted by smartphones, tablets, laptops, and many other electronic devices, is impacting on the quantity and quality of our sleep. Darkness is a natural cue to our bodies that it’s time for sleep, but we’re circumventing it by staring at bright screens for hours in the evening. “There are about 30,000 cells inside your eye that are reactive to the wavelength of light which would be considered blue,” explains clinical psychologist and sleep therapist, Dr. Michael J. Breus. “Blue runs in about the 460 nanometer range, in terms of the spectrum of light. That particular spectrum of light hits these cells and makes them send a signal to an area of the brain and tells it to turn off melatonin production. Melatonin is the key that starts the engine for sleep.”
