Light is essential not only for visual perception but also for regulating various physiological and behavioral processes in humans. In the current increasingly urbanized and indoor-centric lifestyles, understanding the relationship between lighting and these components of human functioning is very important. This study aims to investigate the efficacy of controlled, intermittent exposure light on sleepiness, alertness, mood, and cognitive functions in young adults. The findings of this study will contribute to a better understanding of how lighting conditions can enhance the overall well-being. This could lead to broader applications for clinical populations dealing with sleep disorders, mood disorders, and cognitive impairments.
