“A considerable amount of research has been dedicated to showing how meditation positively affects gene expression. One study conducted at the University of Wisconsin–Madison, published in the journal Psychoneuroendocrinology in 2013, revealed that meditators, after only eight hours of meditation, experienced clear genetic and molecular changes, including decreased levels of pro-inflammatory genes, which would enable them to physically recover from stressful situations more quickly.10 Church says that when we meditate, we are “bulking up the portions of our brains that produce happiness.”11”
