A selected stress reduction approach, the Transcendental Meditation program, may be useful as an adjunct in the long-term treatment of hypertension in African Americans.

Standard ambulatory night sleep electroencephalograph (EEG) of 11 long-term practitioners of the Transcendental Meditation (TM) program reporting "higher states of consciousness" during sleep (the experimental group) was compared to that of nine short-term practitioners and 11 non-practitioners. EEG tracings during stages 3 and 4 sleep showed the experimental group to have: 1) theta-alpha activity simultaneously with delta activity and 2) decreased chin electromyograph (EMG) during deep sleep (p = 0.002) compared to short-term practitioners. Spectral analysis fast Fourier transform (FFT) data of the first three cycles showed that: 3) the experimental subjects had significantly greater theta 2 (6-8 Hz)-alpha 1 (8-10 Hz) relative power during stages 3 and 4 than the combined control groups [t(30) = 5.5, p = 0.0000008] with no difference in time in delta; 4) there was a graded difference across groups during stages 3 and 4 in theta 2-alpha 1 power, with experimentals having greater power than short-term practitioners, who in turn had greater power than non-practitioners [t(30) = 5.08, p = 0.00002]; and 5) experimentals also had increased rapid eye movement (REM) density during REM periods compared to short-term practitioners (p = 0.04). Previous studies have found increased theta-alpha EEG activity during reported periods of "transcendental consciousness" during the TM technique. In the Vedic tradition, as described by Maharishi Mahesh Yogi, transcendental consciousness is the first of a sequence of higher states. The maintenance of transcendental consciousness along with deep sleep is said to be a distinctive criterion of further, stabilized higher states of consciousness. The findings of this study are interpreted as physiological support for this model.

Overall, TM practice is more effective than treatment as usual and most alternative treatments, with greatest effects observed in individuals with high anxiety. More research is needed in this area, especially with high-anxiety patients, conducted under medically supervised conditions.

This field study compared 5 years of medical insurance utilization statistics of approximately 2000 regular participants in the Transcendental Meditation (TM) program with a normative data base of approximately 600,000 members of the same insurance carrier. The benefits, deductible, coinsurance terms, and distribution by gender of the TM group were very similar to the norm, yet the TM group had lower medical utilization rates in all categories. Inpatient days per 1000 by age category were 50.2% fewer than the norm for children (0-18), 50.1% fewer for young adults (19-39), and 69.4% fewer for older adults (40+). Outpatient visits per 1000 for the same age categories were, respectively, 46.8%, 54.7%, and 73.7% fewer. When compared with five other health insurance groups of similar size and professional membership, the TM group had 53.3% fewer inpatient admissions per 1000 and 44.4% fewer outpatient visits per 1000. Admissions per 1000 were lower for the TM group than the norm for all of 17 major medical treatment categories, including -55.4% for benign and malignant tumors -87.3% for heart disease, -30.4% for all infectious diseases, -30.6% for all mental disorders, and -87.3% for diseases of the nervous system. However, the TM group's admission rates for childbirth were similar to the norm. The issue of self-selection is addressed in terms of previous medical research in this area.
