Artificial light, although necessary for us to live in a modern society that operates after dark, is actually something that should be absorbed in moderation. Too much artificial, electric light can have severe long-term effects on the human body. Contrary to popular belief, inadequate natural light during the day and too much artificial light at night not only disrupts our sleep cycles, but also our core body temperatures, eating habits and digestion, hormone regulation/release, and patterns of gene expression throughout our bodies. The amount and brightness of this light doesn’t necessarily matter because all light, no matter how dim, can have the exact same impact on our circadian rhythms -- the 24-hour clock all humans run on. Natural light, on the other hand, may hold the key to correcting these disruptions. By informing users of the type and temperature of ambient light they’re taking in, as well as prompting a user when it’s almost time to turn out the lights completely, LUMINOUS aims to help people return to their natural health cycles.
