Summary
This paper examines how daytime light exposure produces acute alerting effects, with a focus on the role of intrinsically photosensitive retinal ganglion cells (ipRGCs) in mediating these responses. Practical implications include optimizing daytime lighting in workplaces and other settings to enhance alertness and cognitive performance through targeted spectral and intensity choices.
