A healthy brain not only supports your intelligence, but emotional regulation, stress level, and other things that support your professional success. Studies showed that those with a strong meditation background had increased gray matter in several areas of the brain, including the auditory and sensory cortex, as well as insula and sensory regions. Neuroscientists found that the meditators had more gray matter in another brain region, this time linked to decision-making and working memory: the frontal cortex. In fact, while most people see their cortexes shrink as they age, 50-year-old meditators in the study had the same amount of gray matter as those half their age.
