People who follow the ancient practice of yoga may be getting an added health
boost, with a new study suggesting it can fight high blood pressure - also known
"This study confirms many people's feelings that exercise may be useful in
the control of hypertension," said Dr Howard Weintraub, a cardiologist and
associate professor of medicine at NYU Langone Medical Center in New York City.
Weintraub was not connected to the new study.
Based on the new findings, "yoga would be a useful adjunct in the lowering of
blood pressure in certain populations," he said.
How the study was done
In the study, researchers led by Dr Debbie Cohen of the University of
Pennsylvania tracked 58 women and men, aged 38 to 62, for six months.
Although the study couldn't prove a cause-and-effect relationship, doing yoga
two to three times a week was associated with an average drop in blood pressure
readings from 133/80 to 130/77, the researchers said.
In comparison, the average decrease in blood pressure was smaller (134/83 to
132/82) among people who ate a special diet but did not do yoga.
In a bit of a surprise, doing yoga in tandem with a special diet did not
outperform doing yoga alone - blood pressure numbers fell only slightly (135/83
to 134/81) among people who ate a special diet and also did yoga, the
The small decline in blood pressure among people who ate a special diet and
did yoga may be because doing both required a greater amount of time, making it
more difficult for participants to stick with their regimens, the authors
Weintraub said the study shows that "yoga can have a favourable effect" on
hypertension. Although the amount of change was small, he said, "some large
population studies have suggested that changes of this magnitude could have very
significant long-term benefits."
To better health
The study did have some limitations, including its relatively short length
and the fact that most participants were young and had milder forms of high
blood pressure, Weintraub said.
Another expert agreed that the ancient Indian practice of yoga might ease
"Yoga, along with deep breathing exercises, meditation and inner reflection,
is a good adjunctive and integrative cardiovascular approach to better health,
including lowering blood pressure, as this data suggests," said Dr David
Friedman, chief of Heart Failure Services at the North Shore-LIJ Plainview
"In addition to proper diet and aerobic physical fitness most days of the
week, I recommend that my patients take time each day for the above measures of
finding disciplined inner peace, for improved health and well-being," he
The findings were presented at the annual scientific meeting of the American
Society of Hypertension, in San Francisco. Findings presented at medical
meetings typically are considered preliminary until published in a peer-reviewed
