Even though this is something we runners have known all along, scientific proof comes to us via the Ririan Project
Research suggests that people who get plenty of physical exercise can wind up with better brains. Scientists at the Salk Institute for Biological Studies in La Jolla, Calif., found that adult mice who ran on an exercise wheel whenever they felt like it gained twice as many new cells in the hippocampus, an area of the brain involved in learning and memory, than mice who sat around all day discussing Lord of the Rings in Internet chat rooms. The researchers weren’t sure why the more active rodents’ brains reacted the way they did, but it’s possible that the voluntary nature of the exercise made it less stressful and therefore more beneficial. Which could mean that finding ways to enjoy exercise, rather than just forcing yourself to do it, may make you smarter – and happier, too.
