http://psychcentral.com/news/2013/05/04/meditation-produces-opposite-effect-of-fight-or-flight/54449.htmlA new study reveals that practitioners of meditation experience changes in gene expression that are the exact opposite of what occurs during the “flight or fight” stress response.
Specifically, genes associated with energy metabolism, mitochondrial function, insulin secretion, and telomere maintenance are turned on, while those involved in inflammation are turned off.
These effects are more significant and consistent for long-term practitioners.
