Meditation and Yoga Switch Off Stress Genes

The mechanism behind how relaxation techniques like yoga, meditation, and prayer improve health has been identified by scientists.

Research collaborators from the Benson-Henry Institute for Mind/Body Medicine at Massachusetts General Hospital (MGH) and the Genomics Center at Beth Israel Deaconess Medical Center (BIDMC) say that such relaxation techniques work by changing patterns of gene activity that affect how the body responds to stress.

The changes were seen in long-term practitioners as well as in newer recruits during the study, published the open-access journal PLoS.

"It's not all in your head. What we have found is that when you evoke the relaxation response, the very genes that are turned on or off by stress are turned the other way. The mind can actively turn on and turn off genes. The mind is not separated from the body," Live Science quoted Dr. Herbert Benson, president emeritus of the Benson-Henry Institute for Mind/Body Medicine at Massachusetts General Hospital and an associate professor of medicine at Harvard Medical School, as saying.

Dr. Gerry Leisman, director of the F.R. Carrick Institute for Clinical Ergonomics, Rehabilitation and Applied Neuroscience at Leeds Metropolitan University in the U.K., agreed: "It's sort of like reverse thinking: If you can wreak havoc on yourself with lifestyle choices, for example, [in a way that] causes expression of latent genetic manifestations in the negative, then the reverse should hold true."
