Interesting--and significant... At the right time of day, blue light is a good thing. It talks to our 24-hour circadian clock, telling our bodies, for example, when to wake up, eat and carry out specific metabolic functions. In plants, blue light signals them to leaf out, grow, blossom and bloom. In animals, it aids migratory patterns, sleep and wake cycles, regulation of metabolism, as well as mood and the immune system. But too much blue light—especially at the wrong time—throws biological signaling out of whack. As a society, we are using more technology, and theres increasing evidence that artificial light has had a negative consequence on our health, said Zoltowski, an assistant professor in SMUs Department of Chemistry. phys.org/news/2014-12-decoding-blue-mysterious-ability-body.html#jCp
