It is already scientifically proven that exposure to a lot of blue light (or a lot of cold white light, which has a significant amount of blue in it) messes with the body’s melatonin-secreting cycle, desynchronizing the internal clock of the body and, by that, affecting the normal functioning of almost all processes in the body.

That’s exactly why there’s a lot of publicity about avoiding looking at any kind of electronic device screen with at least two hours before going to sleep, or using various methods to diminish the blue light ratio in the overall light given off by electronic device displays.

During a recent a study, scientists in the Brain-Computer Interface Lab at the University of Granada have discovered something interesting about the influence blue light can have on the brain.

They discovered that exposure to blue light can actually help the brain relax and recover after exposure to acute psychological stress (like an argument with someone you care about). In the above-mentioned study, the researchers used a group of twelve healthy adults, aged from 18 to 37, which they exposed to acute psychological stress using the MIST (Montreal Imaging Stress Task) method.

The subjects were asked to do mathematical calculations while exposed to socially stressful circumstances. The second step of the process was a session of relaxation in a chromatherapy room (using colored light to obtain mental or physiological changes).

Six of the twelve people were exposed to white light, while the other six were exposed to blue light. The scientists were monitoring and recording the heart rate and brain activity patterns of all subjects during the whole length of the session.

The result showed that the subjects in the group exposed to blue light managed to relax about three times faster than the subjects exposed to white light. This result could have applications not only in clinical environments (where psychologists and other experts can incorporate it in their light therapies) but also in education-related environments and even in our daily life.
