In the Christmas season, we become even more aware that light affects mood, and a new study indicates that light may also play a role in modulating fear and anxiety. So whether or not you’ve switched, turn on the lights (just avoid standing under those spy streetlights)!read more
Sleep with the blinds closed! Exposure to even dim light at night is enough to cause physical changes in the brains of hamsters (and humans?) that may lead to depression.

People who witness UFOs often comment that they shine a bright lights onto the ground in a single color: blue. Now science may have made some progress in finding out what’s so important about blue light. The world turns out to be a lot stranger than we used to think it was.
Human eyes can only see light in a very small region of the electromagnetic spectrum. For us, visible light corresponds to a wavelength range of 400 – 700 nanometers in a color range of violet through red. Blue light has a wavelength of about 475 nm, one of the shortest in the light spectrum. The human eye is more sensitive to short-wavelength light, which produces “cool” tones like blue or green, as opposed to long-wavelength light, which produces “warm” tones like yellow and red.
