A study of health insurance statistics on over 2,000 people practicing the Transcendental Meditation program over a 5-year period found that the Transcendental Meditation meditators consistently had less than half the hospitalization than did other groups with comparable age, gender, profession, and insurance terms. The difference between the Transcendental Meditation and non-Transcendental Meditation groups increased in older-age brackets. In addition, the Transcendental Meditation meditators had fewer incidents of illness in 17 medical treatment categories, including 87% less hospitalization for heart disease and 55% less for cancer.
