Using Blue Light To Our Advantage
A recent New York Times article in the health section explains the idea that exposure to light at night can suppress one’s production of melatonin, a hormone that promotes sleep, and thus disrupts our 24-hour circadian cycle. It also expands on more recent experiments showing that specifically blue light is especially effective at suppressing our release of melatonin, and in fact, keeps us more awake and alert.
What does this mean for us in the lighting world?
Most LEDs for general lighting use blue LEDs with specific phosphors that change this near-ultraviolet light into white light. At night these blue lights are disrupting our sleep patterns, but in the day, they are helping us keep alert and stay awake.
What if we had lights that changed their wavelength throughout the day corresponding to the activity we were performing? Is this the future of lighting? Please let us know what you think in the comments!
