Those who get bogged down by incessant arguments in office or home can turn to blue lighting immediately to relax faster and cool down from the heat of an agitated mind, said researchers from the University of Granada.
The researchers from the BCI Lab (Brain-Computer Interface Lab) at the University of Granada, found that psychosocial stress produces some physiological responses that can be measured by bio-signals. Since this stress is very common and affect people's health and quality of life, the new remedy may be helpful, stressed the scientists.
Researchers proved that after an objective evaluation using electrophysiological measurements, blue lighting accelerates the relaxation process after acute psychosocial stress compared to sitting under a conventional white lighting, usually seen in offices or homes.
Stress is a kind of short-term phenomenon that occurs during social or interpersonal relationships, while arguing with a friend or when someone pressures you to finish a certain task as soon as possible, with deadline hovering over your mind.
The results of the recent study, published in the PlosOne journal, show that the experiment on 12 volunteers to be stressed and then perform a relaxation session within the multisensory stimulation room at the School for Special Education San Rafael, proved far more rewarding.
In the 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 with an electrocardiogram and an electroencephalogram, respectively, gave out the positive and faster results in blue lighting than in white lighting.
The research was led by Francisco Pelayo and was carried out by researcher Jesús Minguillón, professor Miguel Ángel López Gordo and the bachelor student Diego Adrián Renedo Criado, in collaboration with Dr. María José Sánchez Carrión of the School for Special Education San Rafael.
