Oxidative stress, which may contribute to aging and chronic diseases like atherosclerosis, was lower in older adults who practiced the Transcendental Meditation technique compared to those who did not. Long-term practitioners (average 16.5 years) had serum lipid peroxide levels 15% lower than controls, as measured by the TBARS assay. The two groups did not differ in smoking, fat intake, or vitamin supplementation, and the lower red meat consumption among meditators did not account for the difference. These preliminary results suggest that stress reduction through Transcendental Meditation may be associated with reduced oxidative stress, though prospective trials are needed to confirm a causal effect.
A review of 24 studies on Transcendental Meditation (TM) for treating and preventing substance misuse found positive effects across all studies, including those with noninstitutionalized users, treatment program participants, and prisoners with heavy use histories. While some survey studies could not exclude self-selection or responder biases, longitudinal random-assignment studies with objective measures also showed positive results. The evidence indicates TM addresses multiple factors underlying chemical dependence, offering immediate distress relief and long-term improvements in well-being, self-esteem, personal empowerment, and psychophysiological health.
