Blood Pressure Slowing the breathing rate has been shown to reduce blood pressure. Within a few minutes, the muscles surrounding the small blood vessels dilate [relax], allowing blood to flow more freely, resulting in lower blood pressure. The research cited below shows that with a breath rate of 10 breaths per minute, blood pressure is reduced up to 36 points systolic and 20 points diastolic. Average reductions in seven clinical tests were 14/9 points. Heart Rhythm Meditation lowers the breathing rate even farther to 5 breaths per minute. Advanced practitioners reach 3 breaths per minute. We do not have data yet on how much more this lowers the blood pressure beyond that shown at 10 breaths per minute. We have found that the average person can easily learn to reduce their breath rate to 5 breaths per minute, without the use of any monitors or instruments, through Heart Rhythm Meditation. Five breaths per minute is accomplished with a six-second inhale and a six-second exhale. "Normal" Blood Pressure May Still Be Too High A new study of heart disease patients finds that "normal" blood pressure may not be low enough. By reducing their pressure well below the levels suggested by national guidelines, patients had fewer heart attacks, strokes, cardiac arrests, hospitalizations for chest pain, and procedures to open blocked coronary arteries. The study showed that the risk of heart attacks increased continuously as systolic blood pressure climbed above 115. (Reported in the NY Times, Nov. 10, 2004)

Research Studies in Peer-Reviewed Publications

These studies are cited by the makers of "Resperate", an electronic device that guides one into rhythmic breathing. Heart Rhythm Meditation also creates rhythmic breathing, at an even slower rate, without an instrument, by feeling the pulse or heartbeat.
