It’s widely accepted that yoga, meditation and other practices that involve conscious relaxation can reduce stress and enhance a person’s general well-being. But for many, notions of “mindfulness” and “wellness” still come off as a tad New Age-y and amorphous.
So here, for skeptics, is a molecular-level reality check: Researchers at Massachusetts General Hospital and Beth Israel Deaconess Medical Center report that the relaxation response – a state of deep rest attained through breathing, meditation, yoga and other practices — triggers changes in gene expression that can affect the body’s immune function, energy metabolism and insulin secretion. The new research — the first to look at rapid, gene-level changes following the relaxation practice — is published in the journal PLOS ONE.
Herbert Benson, a senior author of the new study, first described the “relaxation response” — what he calls the physiologic opposite of fight-or-flight — nearly 40 years ago. He’s now the director emeritus of the Benson-Henry Insitute for Mind-Body Medicine at MGH, where the technique is used to help patients manage a wide variety of medical conditions from anxiety and chronic pain to cancer.
Benson says the new research should give a credibility boost to his endeavors (which, by the way, non-Westerners have been practicing in various forms for thousands of years). “There’s now a scientific basis for these mind-body approaches that work,” Benson said. “For the mainstream, every little bit of evidence helps.”
Benson’s collaborator, Towia Libermann, PhD, director of the Beth Israel Deaconess Medical Center (BIDMC) Genomics, Proteomics, Bioinformatics and Systems Biology Center and co-senior author of the study, says the evidence clearly links the relaxation response to rapid changes in gene expression. “There is a relatively small subset of biological pathways affected by relaxation response,” he said. For instance, a pathway involved in immune disturbances and inflammation was repressed after the relaxation technique while another set of pathways involved in mitochondrial function and energy production were enhanced.
