Systolic Blood Pressure and Long-Term Practice of the Transcendental Meditation® and TM-Sidhi Program: Effects of TM on Systolic Blood Pressure

Systolic blood pressure was measured in 112 subjects practicing the Transcendental Meditation (TM) and TM-Sidhi programs. The subjects were between the ages of 35 and 64 years. A significant difference was found between the systolic blood pressures of subjects (matched for sex, race, and general educational background) practicing the TM and TM-Sidhi programs and norms for the general population. This difference was independent of diet and exercise patterns but related to length of time meditating. A significant difference was also found between short-term (under 5 years) and long-term (over 5 years) participants of the TM program, covarying for age. No previous reports exist concerning the long-term effects of the TM program on blood pressure. Despite methodological problems associated with cross sectional data, the findings suggest the beneficial effects of the long-term practice of the TM and TM-Sidhi programs on systolic blood pressure. Even if self-selection plays a role, the characteristics of an easily identifiable group already showing traits beneficial to the general population deserves further study.
