Studies show that exercising your brain can improve its health and functioning, in the same way that exercise can improve your physical health. Fit Brains is a new site from Vivity Labs that offers brain fitness products that are fun and engaging, but also stimulate cognitive functioning of the brain. There are currently four games up on the site (with titles like “Crime Scene Shuffle” and “Deep Blue Expedition”), with a fifth coming soon, and all are free. A paid, premium service is in the works. In addition to the games, FitBrains.com also provides tools to measure your personal brain fitness, and the games can then be personalized to your own brain metrics. Fit Brains also integrates social networking aspects and hosts brain teaser competitions (some of which require teamwork), to stimulate social functioning of the brain too. In the Brain Science section of FitBrains.com, you can learn more about the science behind Fit Brains and read up on lifestyle changes that can also improve brain fitness.
