Although it is environmentally friendly, blue light can affect your sleep and potentially cause disease. Until the advent of artificial lighting, the sun was the major source of lighting, and people spent their evenings in relative darkness. Now, in much of the world, evenings are illuminated, and we take our easy access to all those lumens pretty much for granted. But we may be paying a price for basking in all that light. At night, light throws the body's biological clock—the circadian rhythm —out of whack. Sleep suffers. Worse, research shows that it may contribute to the causation of cancer, diabetes, heart disease, and obesity. Not all colors of light have the same effect.
