Philadelphia, Pa. (October 15, 2013) -- Blood pressure is effectively lowered by mindfulness-based stress reduction (MBSR) for patients with borderline high blood pressure or "prehypertension." This finding is reported in the October issue of Psychosomatic Medicine: Journal of Biobehavioral Medicine, the official journal of the American Psychosomatic Society. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.

"Our results provide evidence that MBSR, when added to lifestyle modification advice, may be an appropriate complementary treatment for BP in the prehypertensive range," writes Joel W. Hughes, PhD, of Kent State (Ohio) University and colleagues.

Mindfulness Practice Leads to Drop in Blood Pressure

The study included 56 women and men diagnosed with prehypertension -- blood pressure that was higher than desirable, but not yet so high that antihypertensive drugs would be prescribed. Prehypertension receives increasing attention from doctors because it is associated with a wide range of heart disease and other cardiovascular problems. About 30% of Americans have prehypertension and may be prescribed medications for this condition.

One group of patients was assigned to a program of MBSR: eight group sessions of 2 hours per week. Led by an experienced instructor, the sessions included three main types of mindfulness skills: body scan exercises, sitting meditation, and yoga exercises. Patients were also encouraged to perform mindfulness exercises at home.

The other "comparison" group received lifestyle advice plus a muscle-relaxation activity. This "active control" treatment group was not expected to have lasting effects on blood pressure. Blood pressure measurements were compared between groups to determine whether the mindfulness-based intervention reduced blood pressure in this group of people at risk of cardiovascular problems.

Patients in the mindfulness-based intervention group had significant reductions in clinic-based blood pressure measurements. Systolic blood pressure (the first, higher number) decreased by an average of nearly 5 millimeters of mercury (mm Hg), compared to less than 1 mm Hg with in the control group who did not receive the mindfulness intervention.

Diastolic blood pressure (the second, lower number) was also lower in the mindfulness-based intervention group: a reduction of nearly 2 mm Hg, compared to an increase of 1 mm Hg in the control group.
