High blood pressure -- or hypertension -- is a major risk factor for heart attack and stroke that affects as many as 100 million Americans and 1 billion people worldwide. Decades of research have demonstrated that the relaxation response -- the physiological and psychological opposite of the well-known fight-or-flight stress response that can be achieved through relaxation techniques like yoga or mediation -- can reduce blood pressure in people with hypertension. Exactly how these interventions act on the body to lower blood pressure remains unclear.
A new study led by investigators at Beth Israel Deaconess Medical Center (BIDMC), Massachusetts General Hospital (MGH), and the Benson-Henry Institute for Mind Body Medicine at MGH identified genes associated with the body's response to relaxation techniques and sheds light on the molecular mechanisms by which these interventions may work to lower blood pressure. The findings were published today in the Journal of Alternative and Complementary Medicine.
"Traditionally, hypertension is treated with pharmacologic therapy, but not all patients respond to drug therapy, and many experience treatment-limiting side effects," said co-senior author Randall Zusman, MD, Director of the Division of Hypertension at MGH's Corrigan Minehan Heart Center. "In these patients, alternative strategies are invaluable. In this study, we found that the relaxation response can successfully help reduce blood pressure in hypertensive patients who are not taking medication."
