Questions and Answers on the
Scientific Research
Many people have questions about specific benefits of Transcendental
Meditation. The following topics provide a more detailed discussion
of the scientific research conducted on Transcendental Meditation.
It gives you a concise reference guide to the benefits of the
technique in the areas of mental potential, health, relationships,
business, and society.
TRANSCENDENTAL
MEDITATION AND EYES-CLOSED RESTING
Is there scientific evidence to show that Transcendental Meditation
is different from just resting with your eyes closed?
Yes. Research shows that Transcendental Meditation is unique;
it is much different from eyes-closed rest.
A comprehensive statistical "meta-analysis" was
conducted that compared the findings of 31 physiological studies
on Transcendental Meditation and on resting with eyes closed.
(A meta-analysis is the preferred scientific procedure for drawing
definitive conclusions from large bodies of research.) The study
evaluated three key indicators of relaxation and found that Transcendental
Meditation provides a far deeper state of relaxation than does
simple eyes-closed rest. The research showed that breath rate
and plasma lactate decrease, and basal skin resistance increases,
significantly more during Transcendental Meditation than during
eyes-closed rest. Interestingly, immediately prior to the Transcendental
Meditation sessions, meditating subjects had lower levels of
breath rate, plasma lactate, spontaneous skin conductance, and
heart rate than did controls. This deeper level of relaxation
before starting the practice suggests that reduced physiological
stress through Transcendental Meditation is cumulative. (American
Psychologist 42: 879-881, 1987.)
COMPARISON
OF ALL TECHNIQUES
Are all meditation and relaxation techniques equally as effective
as Transcendental Meditation?
No. All meditation and relaxation techniques are not the same.
Four studies were conducted that compared findings of research
on different meditation and relaxation techniques. These meta-analyses
found that Transcendental Meditation is the most effective technique
for reducing anxiety; increasing self-actualization; reducing
alcohol, cigarette, and drug abuse; and improving psychological
health.
- Reduced anxiety -- A statistical meta-analysis of
146 previously conducted studies indicated that compared with
every other meditation and relaxation technique tested to date,
Transcendental Meditation is much more effective at reducing
anxiety, the most common sign of psychological stress. (Journal
of Clinical Psychology 45: 957-974, 1989.)
- Increased self-actualization -- A second meta-analysis
of 42 studies found that Transcendental Meditation was significantly
more effective in increasing self-actualization than other meditation
and relaxation techniques. (Journal of Social Behavior and
Personality 6: 189-247, 1991.)
- Reduced substance abuse -- A third meta-analysis of
198 studies found that Transcendental Meditation was significantly
more effective in reducing drug, alcohol, and cigarette abuse
than were standard treatment and prevention programs, including
relaxation. (Alcoholism Treatment Quarterly 11: 13-87,
1994.)
- Improved psychological health -- A fourth meta-analysis
of all relevant, previously conducted research -- 51 studies
in all -- showed that compared with every other meditation and
relaxation technique tested to date, Transcendental Meditation
is far more effective at enhancing psychological health and maturity.
The studies showed that Transcendental Meditation promotes greater
overall self-actualization, as indicated by increased self-regard,
spontaneity, inner directedness, and capacity for warm interpersonal
relations. (Dissertation Abstracts International 42(4):
1547, 1980.)
HYPERTENSION
Does Transcendental Meditation lower high blood pressure?
Yes. More than 30 million Americans suffer from high blood
pressure, one of the most serious risk factors for heart disease.
Sixteen studies have clearly demonstrated the positive effects
of Transcendental Meditation on hypertension.
For example, a recent study was conducted on 128 inner-city,
elderly African-Americans with hypertension. They were randomly
assigned to either the Transcendental Meditation technique, progressive
muscle relaxation, or a usual-care control group. All subjects
followed the same diet and exercise regimen. After 3 months Transcendental
Meditation produced an 11-point decrease in systolic blood pressure
and a 6-point decrease in diastolic blood pressure, compared
to untreated controls, and more than twice the reduction in blood
pressure produced by progressive muscle relaxation. (Personality,
Elevated Blood Pressure, and Essential Hypertension, Johnson,
Gentry, and Julius (eds.). Hemisphere, Washington, D.C., 291-312,
1992.)
CHOLESTEROL
Does Transcendental Meditation reduce cholesterol levels?
Yes. Cholesterol is also a major risk factor in heart disease.
A longitudinal study showed that cholesterol levels significantly
decreased through Transcendental Meditation in hypercholesterolemic
patients, compared to matched controls, over an 11-month period.
(Journal of Human Stress 5 (4): 24-27, 1979.)
REDUCED
HEALTH CARE COSTS
Is there any evidence to show that Transcendental Meditation
can lower health care costs?
Yes. Spiraling health care costs in the U.S. pose a dangerous
threat to the health and financial well-being of individuals,
institutions, and the government. The only permanent solution
to the health care crisis is to make people healthier. Transcendental
Meditation has been shown to be most effective in promoting health
and reducing health care utilization and medical fees, compared
to other wellness and health promotion programs.
- Reduced health care utilization -- A large study of
the insurance statistics of 2,000 Transcendental Meditation participants
over a 5-year period gives an indication of what could happen
if Transcendental Meditation were incorporated into existing
health care programs. The study found that the Transcendental
Meditation group had 50% less of the medical care utilization,
both in-patient and out-patient, compared to controls matched
for age, gender, and occupation. The Transcendental Meditation
group had lower sickness rates in all categories of disease,
including 87% less hospitalization for heart disease and 55%
less for cancer. The difference between the Transcendental Meditation
and non-Transcendental Meditation groups was greatest for individuals
over 40 years of age. (Psychosomatic Medicine 4:, 493-507,
1987.)
- Reduced health care expenses -- A study of 599 Transcendental
Meditation participants in Quebec, Canada, found an average 12%
reduction in medical expenses each year over a 3-year period.
In the 3 years before starting the technique, the group's medical
expenses had been equivalent to the norms for the same age and
sex. Medical fees for "high-cost" individuals and older
people decreased by 19% annually. (Dissertation Abstracts
International 53(12:) 4219-A, 1993.)
AGING
What effect does Transcendental Meditation have on aging?
Successful aging is the best indication of how effectively
an individual handles the stresses of life. Transcendental Meditation
has proven highly effective in promoting successful aging.
- Younger biological age (1) -- A study comparing people
practicing Transcendental Meditation who were an average age
of 50-years-old to matched controls on the Adult Growth Examination
(a test measuring indicators of biological age: systolic blood
pressure, auditory threshold, and near-point vision) found that
the biological age of long-term participants in the Transcendental
Meditation program was, on average, 12 years less than their
actual chronological age. This means that a 50-year-old who has
been practicing Transcendental Meditation for 5 years would,
on average, have the biological age of a 38-year-old. (International
Journal of Neuroscience 16: 53-58, 1982.)
- Younger biological age (2) -- Higher levels of plasma
dehydroepiandrosterone sulfate (DHEAS) is a hormonal marker of
younger biological age. This hormone was found to be significantly
higher for 326 adult Transcendental Meditation technique practitioners
than for 972 age- and sex-matched controls. These differences
were largest for the oldest age categories. (Journal of Behavioral
Medicine 15(4): 327-341, 1992.)
- Longer life -- Seventy-three residents of homes for
the elderly (mean age 81 years) were randomly assigned to one
of three treatments which were highly similar in external structure
and expectation-fostering features: Transcendental Meditation,
mindfulness training in active distinction making, and a relaxation
program; while a fourth group received usual care. The Transcendental
Meditation group improved significantly more than did all other
groups on all the measures tested: systolic blood pressure, mental
health, paired-associates learning, two measures of cognitive
flexibility, self-ratings of behavioral flexibility and aging,
and multiple indicators of treatment efficacy. Moreover, after
3 years the survival rate for Transcendental Meditation was 100%,
compared to 65%, 77%, or 88% survival rates for the other treatment
groups, respectively, and 63% for the untreated elderly. These
results indicate that Transcendental Meditation promotes a longer
life and a higher quality of life. (Journal of Personality
and Social Psychology 57(6): 950-964, 1989.)
MENTAL
HEALTH
Has there been research on the effects of Transcendental Meditation
on mental health?
Yes. Transcendental Meditation has been found to improve mental
health by reducing biochemical indicators of stress, decreasing
anxiety, and enhancing psychological development.
- Increased field independence -- A study of perception
found that after 3 months those who learned Transcendental Meditation
increased significantly more than did controls in their ability
to perceive the world more accurately under potentially confusing
conditions. Psychologists call this ability "field independence"
because it indicates the growth of a stable internal frame of
reference that makes the individual more self-sufficient and
independent of the "field" of the physical and social
environment. These individuals have broader comprehension and
improved ability to focus and are better able to see another
person's perspective, while remaining unswayed by social pressure
to do something that they judge to be wrong. (Perceptual and
Motor Skills 39: 1031-1034, 1974.)
- Most effective technique to reduce anxiety -- As previously
cited on page 159, a meta-analysis of 146 previously conducted
studies on the effects on trait anxiety of Transcendental Meditation,
other meditation techniques, and progressive relaxation and other
relaxation techniques, found that Transcendental Meditation had
a significantly greater effect on reducing anxiety than did all
other treatments. This study controlled for a number of possible
variables, including population, age, sex, experimental design,
etc. (Journal of Clinical Psychology 45: 957-974, 1989.)
- Most effective technique for enhancing psychological maturity
-- As previously cited on page 160, a meta-analysis of 51 studies
of different meditation techniques found a significantly larger
effect from Transcendental Meditation, compared to other forms
of meditation, on a wide range of psychological measures, including
anxiety, depression, anger, self-esteem, and internal locus of
control. The result was maintained in the studies of highest
validity and strongest experimental design. (Dissertation
Abstracts International 42(4): 1547, 1980.)
- Less hospital admissions for psychiatric care -- The
Swedish government's National Health Board conducted a nationwide
epidemiological study that found that hospital admissions for
psychiatric care were 150-200 times less common among the 35,000
people practicing Transcendental Meditation in Sweden, than for
the population as a whole. (Suurkula, University of Gothenburg,
Vasa Hospital, Gothenburg, Sweden, 1977.)
EDUCATION
Is there research on the effects of Transcendental Meditation
in the schools?
Yes. Over 30 years of experience in schools, colleges, and
universities in the U.S. and around the world, and extensive
scientific research, have shown that Transcendental Meditation
improves basic learning skills, increases intelligence, improves
grades, and improves moral reasoning in students.
- Improved basic learning skills -- A study of elementary
school children found that students who practiced Transcendental
Meditation over the course of an academic year significantly
improved in mathematics, reading, language, and study skills.
(Education 107: 49-54, 1986.)
- Improved intellectual performance and self-concept in
inner-city children -- A study of inner-city children found
that through regular practice of the Transcendental Meditation
technique, students increased in analytic intelligence, self-concept,
and general intellectual ability. (Presented at the 98th annual
meeting of the American Psychological Association, Washington,
D.C., August 1990.)
- Increased intelligence -- A study of college students
who practiced Transcendental Meditation at Maharishi International
University in Fairfield, Iowa, found that they improved significantly
on a "culture-fair" (nonverbal) measure of IQ over
a 2-year period, while no change in IQ was found in non-meditating
college students from another Iowa university over the same period.
Subjects' age, education level, level of interest in meditation,
father's education level, and father's annual income were statistically
controlled for in the study. No other procedure has consistently
been found to increase general intelligence in college-age students.
(Maharishi International University integrates the arts, sciences,
and professions with the study and development of consciousness
through the practice of Transcendental Meditation. The University
is accredited to the Ph.D. level by the North Central Association
of Schools and Colleges.) (Personality and Individual Differences
12: 1105-1116, 1991.)
BUSINESS
What effect does Transcendental Meditation have in a business?
Transcendental Meditation has been used in hundreds of businesses
in the U.S. and around the world. Research in several business
settings has found Transcendental Meditation to be a highly effective
corporate development program.
- Improved health and increased job performance -- Transcendental
Meditation proved highly effective in reducing on-the-job stress
and promoting employee health and development, when the technique
was offered in the manufacturing plant of a large Fortune 100
company and in a smaller distribution sales company. The study
found that managers and employees practicing Transcendental Meditation
displayed less anxiety, job tension, insomnia, and fatigue, and
reduced cigarette and hard liquor use, compared to non-meditating
employees. The study also found the Transcendental Meditation
group showed improved health and fewer health complaints, and
enhanced effectiveness, job satisfaction, and work/personal relationships.
(Anxiety, Stress and Coping: International Journal 6:
245-262, 1993.)
- Increased job performance -- A second study found
that Transcendental Meditation increased job productivity and
satisfaction. In addition, relationships with both supervisors
and co-workers improved. (Academy of Management Journal
17: 362-368, 1974.)
- Case history of business success -- A 7-year case
study of a chemical manufacturing company found dramatic increases
in productivity and net income, and decreases in sick days, correlated
with increases in the number of employees in the company practicing
Transcendental Meditation. (Enlightened Management: Building
High Performance People. Maharishi International University
Press, Fairfield, Iowa, 1989.)
- Improved health in Japanese industry -- The Japanese
government's National Institute of Industrial Health, in a controlled
longitudinal study with nearly 800 subjects in one of Japan's
largest companies, found significant improvements in physiological
and mental health in industrial workers who practiced Transcendental
Meditation compared to controls. The meditators showed decreases
in physical complaints, anxiety, depression, smoking, insomnia,
digestive problems, neurotic tendencies, and psychosomatic problems.
(Japanese Journal of Public Health 37(10): 729, 1990;
Japanese Journal of Industrial Health 32(7): 177, 1990.)
TRAUMATIC
STRESS
Has research been done on the effects of Transcendental Meditation
on traumatic stress?
Yes. In a Vietnam veterans center, 18 men suffering from severe
and apparently intractable post-traumatic stress syndrome were
randomly assigned to either the Transcendental Meditation technique
or psychotherapy (multiple modalities). After 3 months of treatment,
the counseling had no significant impact, but Transcendental
Meditation reduced emotional numbness, alcohol abuse, insomnia,
depression, anxiety, and severity of delayed stress syndrome.
Veterans practicing Transcendental Meditation also showed significant
improvement, compared to controls, in employment status. (Journal
of Counseling and Development 64: 212-214, 1985.)
SUBSTANCE
ABUSE
Has Transcendental Meditation been used to prevent and treat
cigarette, drug, and alcohol abuse?
Yes. Cigarette smoking is the largest, non-genetic cause of
death in the U.S. (400,000 people per year), and alcohol is the
third largest cause of death (100,000 per year). Experts estimate
that nearly 80% of crime is drug or alcohol related. Research
has found Transcendental Meditation to be highly effective in
both the treatment and prevention of substance abuse.
- More effective than other programs -- As previously
cited on page 159, a statistical meta-analysis of 198 studies,
which compared all standard treatment and prevention programs
for substance abuse (including Alcoholics Anonymous, individual
counseling, educational programs, anti-smoking courses, anti-drug
programs, and self-esteem training), found that Transcendental
Meditation was far more effective than all these other approaches.
(Alcoholism Treatment Quarterly 11: 13-87, 1994.)
- 81% quit or decreased cigarette smoking -- In a prospective
study of 324 smoking adults -- 110 who started Transcendental
Meditation and 224 matched controls who did not start -- significantly
more (51%) of the Transcendental Meditation participants quit
smoking, compared to 21% for non-meditating controls. When reduction
of smoking (at least five cigarettes less per day -- a 25% average
decrease) was considered along with cessation, 81% of the regular
Transcendental Meditation participants quit or decreased smoking,
compared to 33% for the non-meditating controls. (Alcoholism
Treatment Quarterly 11: 219-236, 1994.)
- 65% abstinence rate in alcoholism treatment -- In
a study funded by the National Institute of Alcohol Abuse and
Alcoholism, 108 transient, chronic alcoholic patients were randomly
assigned to learn Transcendental Meditation, standard drug counseling,
or two other programs. Transcendental Meditation was significantly
more effective than all other treatment programs. For example,
after 18 months, 65% of the Transcendental Meditation group were
abstinent, compared to 25% for standard drug counseling. (Alcoholism
Treatment Quarterly 11: 185-218, 1994.)
- 89% reduction in use of illicit drugs -- An 18-month
study of 115 high school- and college-age drug users in an out-patient
drug rehabilitation center in Germany showed that the Transcendental
Meditation group had significantly greater reductions in drug
usage and improvements in psychological health, compared to matched
controls of comparable age, gender, and severity and type of
drug consumption who received only standard out-patient drug
counseling. After 4 months of Transcendental Meditation, drug
use dropped 50%; after 18 months, 89%. (Zeitschrift fur Klinische
Psychologie 7: 235-255, 1978.)
CRIMINAL
REHABILITATION
Has Transcendental Meditation been used in prisons?
Yes, very successfully.
Currently, about 1.4 million Americans are behind bars, and
experts agree that conventional approaches to rehabilitating
prisoners have failed. In fact, nearly two-thirds of all inmates
who are paroled return to prison within 3 years -- often after
committing further violent crimes. In the past 20 years, Transcendental
Meditation has been taught to thousands of adult inmates in 18
U.S. correctional institutions and to hundreds of incarcerated
juveniles in 8 U.S. facilities. It has also been used in prisons
in 12 other countries. Research has found Transcendental Meditation
to be very effective in rehabilitating offenders and reducing
recidivism (the rate at which offenders return to prison).
- 33-38% reduction in recidivism -- In a study conducted
by Harvard researchers of 133 maximum- security inmates, those
who learned Transcendental Meditation decreased significantly
in aggression and mental disorders, and increased markedly in
psychological maturity, compared to matched controls and matched
participants in four other treatment programs. Inmates practicing
Transcendental Meditation also had recidivism rates 33-38% less
than those of the four other treatment groups and the control
group, over a 3 1/2 year period. (Dissertation Abstracts International
43(2): 539-B, 1982.)
- 35-40% reduction in recidivism -- In a 5-year study
of 259 male felons in California who had been paroled from such
prisons as Folsom and San Quentin, the Transcendental Meditation
group had 35-40% less recidivism than did matched controls. Other
programs, including vocational training, psychotherapy, and prison
education, did not consistently reduce recidivism. (Journal
of Criminal Justice 15: 211-230, 1987.)
- Large-scale study in Senegal -- In Senegal, West Africa,
in 1987, President Abdou Diouf introduced the Transcendental
Meditation program into 31 prisons nationwide. More than 11,000
prisoners and 900 correctional officers learned the technique.
Violence in the prisons decreased markedly and recidivism rates
dropped from 90% to about 8%. The Director of Penitentiary Administration
in Senegal Colonel Mamadou Diop credited the Transcendental Meditation
program for the dramatic reduction in recidivism. (Total Rehabilitation.
Maharishi Vedic University Press, in press.)
- Comprehensive research review -- A narrative and quantitative
review of research projects on Transcendental Meditation in eight
correctional settings indicated that regular practice of Transcendental
Meditation consistently leads to positive changes in health,
personality development, and behavior, as well as lower recidivism,
among inmates. (International Journal of Comparative and Applied
Criminal Justice 11: 111-112, 1987.)
QUALITY
OF LIFE
Is there evidence that people practicing Transcendental Meditation
have a positive effect on society as a whole?
Yes. More than 40 studies have shown that group practice of
Transcendental Meditation and the more advanced TM-Sidhi Program
reduces social stress, as indicated violence, crime, and international
conflict in society and improves economic vitality and governmental
efficiency. (For a discussion of the mechanics of this effect,
please see Chapter 7, "Reducing
Crime in Society and Creating World Peace.")
How did scientists measure this? To evaluate the potential
impact of the Transcendental Meditation and TM-Sidhi Program
on society, researchers assessed many variables, including crime
rate, violent fatalities (homicides, suicides, and motor vehicle
fatalities), armed conflict, economic indicators, and broad quality-of-life
indices, which include the above variables as well as rates of
notifiable diseases, hospital admissions, infant mortality, divorce,
cigarette and alcohol consumption, and GNP.
The results indicated that the effects for each of these variables,
or for overall indices, consistently changed in the direction
of improved quality of life when a sufficiently large group of
people were practicing the Transcendental Meditation and TM-Sidhi Program in society.
The following are summaries of four studies published in peer-reviewed
scientific journals.
- Decreased crime rate in 24 U.S. cities: Twenty-four
cities that reached 1% of their populations practicing the Transcendental
Meditation program in 1972 were found to have significant reductions
in crime trend during the 6-year experimental period from 1972-1977,
compared to 24 control cities matched for total population, college
population, and geographic region. Even when statistically controlling
for specific demographic factors known to affect crime, such
as median years of education, stability of residence, and pre-intervention
crime rate, the crime trends in the 1% cities were still significantly
lower. (Crime and Justice IV: 26-45, 1981.)
- Decreased crime rate in 160 U.S. cities: A study of
a random sample of 160 U.S. cities found that increasing the
numbers of Transcendental Meditation participants in the 160
cities over a 7-year period (1972-1978) was followed by reductions
in crime rate. The study used data from the FBI Uniform Crime
Index total and controlled for other variables known to affect
crime. Causal analysis supported the hypothesis that Transcendental
Meditation caused the reduction in crime. (Journal of Mind
and Behavior 9: 457-486, 1989.)
- Decreased crime rate in Washington, D.C.: A study
of weekly data from October 1981 through October 1983 found that
increases in the size of a large group practicing the Transcendental
Meditation and TM-Sidhi Program in Washington, D.C., were followed
by significant reductions in violent crime. Weekly violent crime
totals in Washington decreased 11.8% during the 2-year period.
Time series analysis verified that this decrease in crime could
not have been due to changes in the percentage of the population
who were of young-adult age, nor Neighborhood Watch programs
nor changes in police polices or procedures. (Journal of Mind
and Behavior 9: 457-486, 1989.)
- Reduced armed conflict and improved quality of life in
the Middle East: This study found that increases in the size
of a group of individuals in Jerusalem practicing the Transcendental
Meditation and TM-Sidhi Program had a statistically significant
effect on improving the quality of life in Jerusalem (automobile
accidents, fires, and crime) and the quality of life in Israel
(crime, stock market, and national mood measured through news
content analysis) and on reducing the war in Lebanon (war deaths
of all factions and war intensity measured through news content
analysis). The effects of holidays, temperature, weekends, and
other forms of seasonality were explicitly controlled for and
could not account for these results. As in many other studies,
the pattern of results supported the hypothesis that the Transcendental
Meditation and TM-Sidhi Program group caused the reduction in
armed conflict and the improvement in the quality of life. (Journal
of Conflict Resolution 32: 776-812, 1988; Journal of Conflict
Resolution 34: 756-768, 1990.)
The accuracy of the results of these and
other studies was strengthened through the use of sophisticated
methods, including:
- statistically controlling for a broad range of demographic
variables, such as population density, median years of education,
age, etc.;
- applying causal "cross-lagged analysis" methods,
which indicated that increasing numbers of people practicing
Transcendental Meditation is followed by corresponding improvements
in society;
- employing "time-series analyses" to control for
seasons, trends, drifts, and rival hypotheses, and to demonstrate
temporal relationships among variables, supporting the hypothesis
that Transcendental Meditation caused these beneficial changes;
- creating large groups of Transcendental Meditation and TM-Sidhi Program participants in various populations to demonstrate positive
changes on specific social indicators, such as crime, and predicting
that these changes would occur.
Moreover, the results of the studies assessing the effect
of group practice of the Transcendental Meditation and TM-Sidhi Program on society are highly statistically significant. The
probabilities that these positive effects could have been due
to chance are very small.
