title: Blue light improves cognitive performance.
abstract: A newly discovered system of photoreceptors for circadian rhythms works non-visual and responds to blue light (460 nm). We report a longitudinal study in 44 adults, showing that a significant increase in alertness and speed of information processing could be achieved by blue light as compared to normal light.
