Still have a morning ritual of drinking a few cups of Joe? Well, researchers at Mid Sweden University compared the effects of caffeine and blue light on the brain and found them both to have a positive effect. Here’s the kicker, people who were exposed to blue light performed better on tests of brain function that included a distraction. Continue reading for two videos and more information.

Here’s what one researcher has to say: “The same distraction, however, proved too much for caffeine users, who performed poorly. Blue light and caffeine demonstrated distinct effects on aspects of psychomotor function. The study builds on research that suggests blue light can improve cognitive abilities such as memory, alertness and reaction time. Although harmless to tissue, blue light is strong enough to trigger biological effects in the body, and it’s being used increasingly for a range of medical treatments.”
