If you ever feel like your emotions are getting the best of you, you may want to try dimming the lights. According to researchers at the University of Toronto Scarborough, bright light can make us more emotional — for better or for worse — making us experience both positive and negative feelings more intensely. The findings seem to contradict commonly held notions that people feel happier and more optimistic on bright, sunny days and gloomier on dark, cloudy days. In fact, the idea for the study was spurred by findings that suicide rates peak in the late spring and summer, when sunshine is most abundant. “I was very surprised by this,” study author Alison Jing Xu told CBC News. Xu is an assistant professor of management at UTSC and the Rotman School of Management. “Normally I would say if brighter days generally increase people’s affect, then suicide rates should peak in winter — but actually it does not,” she said. Xu, along with the study’s co-author Aparna Labroo of Northwestern University in the U.S., conducted six experiments to explore the relationship between light and emotion. Their paper is published in the Journal of Consumer Psychology. Participants in each case were divided into two groups: Some were placed in a brightly lit room where fluorescent ceiling lights were turned on, while others were placed in a dimly lit room where the only light came from computer monitors.
