As a result of improved stability of the physiology and more health related behavior the long-term effect of practicing Transcendental Meditation and better health is measured in this study, done in Quebec, Canada, among 1400 people who began the practice of Transcendental Meditation compared to 1400 matched controls, and before they began with the practice of TM there was virtually no difference between the groups.
After beginning the practice of TM there was a highly significant decrease of about 14% per year of reduction of medical expenses as measured by the government insurance. That means that over the course of 3 years a reduction of approximately 40% could be measured.
