A vast research base shows that contemplative practice has good effects not only on our brains but on every cell in our body. Changes in brain structure and reactivity produced by meditation lead to a greater ability to experience internal sensations, less emotional reactivity, and greater attentional efficiency, among several other important cognitive processes that improved. Meditation also changes the expression of 7 to 8 percent of the genes you have, primarily through epigenetic changes that up- and down-regulate genes involved in the stress response.
