Bright Light’s Impact on Brain Activity and Cognitive Performance

A study from the University of Liège reveals how exposure to bright light can significantly impact brain activity and cognitive performance. Conducted on healthy young adults, the research found that as light levels increased, activity in certain regions of the hypothalamus varied: the posterior portion showed increased activity, while the inferior and anterior portions decreased. Interestingly, higher light levels correlated with improved executive functioning tasks, suggesting a link between brightness and cognitive performance. This insight could pave the way for light therapy treatments targeting sleep problems and alertness issues, offering promising avenues for enhancing mood and cognitive function.
