Can Meditation Help Reduce Heart Disease and Stroke Risk?

Hypertension, or what is more commonly known as high blood pressure, is definitely a risk factor for heart disease and stroke. Therefore, when one is diagnosed with hypertension, his or her doctor will prescribe hypertensive medication for reduction of blood pressure.

Besides drugs, there are also other ways such as diet and exercise can help reduce blood pressure. In fact, a study, which was carried out by researchers from the University of Kentucky in Lexington and published in the American Journal of Hypertension, reported that practicing a particular type of meditation twice a day could significantly reduce blood pressure.

The findings also indicated that the blood pressure reductions associated with regular practice of transcendental meditation (TM) would actually translate to a 12 to15 percent reduced risk of dying from cardiovascular causes and a 15 to 20 percent lower risk of stroke.

Besides TM, there are a number of different types of meditation and relaxation techniques. However, TM is unique in a way that it can bring the practitioner into a quiet zone that acts as some kind of sanctuary for a person, refreshing them and reducing stress.

In TM, a person sits in a comfortable chair for 20 minutes twice a day and attempts to quiet the mind by focusing on a mantra. It is simple but training is required for one to get into it.

In order to understand better the real benefits of practicing TM for people with high blood pressure, the researchers examined 9 trials that compared blood pressure changes in a group of patients practicing TM versus a so-called 'control' group. As some previous research on TM has been criticized as being biased and of poor quality, they analyzed the findings of only 3 clinical trials that they rated as being high quality.

Their analysis showed that TM reduced systolic blood pressure (the top number in a blood pressure reading) by 4.7 points and diastolic blood pressure (the bottom number) by 3.2 points. Sustained blood pressure reductions of such magnitude, according to the researchers, could significantly reduce the risk of heart disease.
