This article explains in detail new research that explores how the colour of light effects our cognitive performance. Kyungah Choi and Hyeon-Jeong Suk who performed the study identified that there is a limit to how intense classroom lighting can be before it starts to disrupt the performance of the students. We have seen studies in the past highlight that exposure to regular patterns of light and dark regulates our circadian rhythm and when disrupted we see an increase in some health conditions such as obesity and diabetes so it makes sense that it would also effect our ability to concentrate. I'm relieved schools and organisations are investing in better lighting but also investing in better health for their students and employees.
The intensity of artificial lighting has been shown to have a range of effects on our mood and our ability to concentrate. New research explores the color of lighting and its effect on our cognitive performance. The study, published in in the journal Optics Express, from The Optical Society (OSA), was conducted by Kyungah Choi and Hyeon-Jeong Suk, associate professor of industrial design at the Korea Advanced Institute of Science and Technology (KAIST) in South Korea and head of the Institute's "color laboratory."
