This study found that those who learned TM showed reduced thickening of the carotid artery. This finding was in contrast to continued thickening of this artery among a control group, shown on the left, who took a health education program on diet and exercise for alleviating cardiovascular problems.

Those who practiced the TM technique showed significantly decreased plasma levels of cortisol during the practice, in contrast to controls. Increased plasma cortisol is an endocrine response to stress, and decreased plasma cortisol thus indicates reduced stress. Reference: Hormones and Behavior 10: 54–60, 1978.

A meta-analysis of all available physiological research on the TM program found that it produces a state of deep rest compared to control conditions, as measured by reduced respiration rate, reduced basal skin conductance (increased skin resistance), and reduced plasma lactate.

Individuals who learned the Maharishi TM program showed increased creativity in comparison to controls as measured by a higher level of pictorial originality when measured after five months of practice.
