Blue lighting is scientifically proven to help us relax faster than white lighting after an argument

Researchers say that blue light accelerates the relaxation process after acute psychosocial stress such as arguing with a friend or when someone pressures you to quickly finish some task.

 

Said stress is a kind of short-term stress (acute stress) that occurs during social or interpersonal relationships, for example while arguing with a friend or when someone pressures you to finish a certain task as soon as possible.

 

The researchers, which belong to the BCI Lab (Brain-Computer Interface Lab) at the University of Granada, note that psychosocial stress produces some physiological responses that can be measured by means of bio-signals. That stress is very common and negatively affects people's health and quality of life.

 

For their work, whose results have been published in the PlosOne journal, the researchers made twelve volunteers to be stressed and then perform a relaxation session within the multisensory stimulation room at the School for Special Education San Rafael.

 

In said room the participants lied down with no stimulus but a blue (group 1) or white (group 2) lighting. Diverse bio-signals, such as heart rate and brain activity, were measured throughout the whole session (by means of an electrocardiogram and an electroencephalogram, respectively).

 

The results showed that blue lighting accelerates the relaxation process, in comparison with conventional white lighting.
