UCLA researchers found that meditation slows the aging process in the brain. People who practice meditation on a regular basis have less brain shrinkage and thickened prefrontal cortexes. This contributes to sharper thought and improved brain function, similar to those of a much younger individual. Regular meditation is also proven to strengthen connections and increase relay time of electrical signals within the brain. These are both qualities reflective of significantly younger brain function. Overall, normal indicators of brain aging are clearly repressed in individuals who regularly practice meditation over long periods of time. In their aging years, meditators are proven to think more sharply than non-meditators.
