The case study conducted by Catalan researchers at the Obos Living Lab in Oslo, Norway, tested a prototype artificial lighting system aimed at simulating natural sunlight and confirmed its effectiveness in improving the psychophysiological state of the test subjects. The study's results demonstrated that biologically optimized lighting simulating the sun is an ideal solution for areas with a lack of sunlight, such as the Nordic countries. This lighting system effectively replaced the insufficient amount of natural daylight, thus reducing negative impacts on health and well-being, such as sleep deprivation and seasonal affective disorder (SAD).
Spending time in the environment with the tested lighting was associated with positive emotions by most participants
The research results show that the primary emotion felt by the research participants after spending time in the tested light was joy for 91%. At the same time, improvements in subjectively perceived well-being were shown in 61% and creativity in 62% of the subjects. These results highlight the need for an artificial lighting system that can offset the lack of sunlight, effectively address related health issues and promote human well-being and vitality.
