A previous investigation has demonstrated that the practice of a meditational technique elicits a wakeful, hypometabolic state. Measurement of O2 consumption and CO2 elimination was made by sampling techniques; mean values of these parameters were calculated from 6–10 minute samples. The present study extends this investigation, using a recently developed method of continuous measurement of O2 consumption and CO2 elimination. Continuous measurement of these parameters permitted the de […]

PHYSIOLOGIC CHANGES consistent with the decreased sympathetic nervous system activity are present during the practice of a relaxation technique, Transcendental Meditation. The changes consist of decreased oxygen consumption, carbon dioxide elimination, respiratory rate and minute ventilation. Arterial blood lactate decreases markedly. Arterial blood pH and base excess decrease slightly. There are no changes in arterial blood pressure, in respiratory quotient, nor in rectal temperature […]

Oxygen consumption, carbon dioxide production, and respiratory rate are significantly decreased during the practice of a new, easily-learned relaxation technique. The elements of the technique are a mental device to prevent distracting thoughts, a passive attitude, decreased muscle tonus, and a quiet environment which is as free of visual and auditory stimuli as possible. Sitting quietly with the eyes either open or closed failed to produce the same changes. These physiologic changes […]

A wakeful hypometabolic state accompanies the practice of a relaxational, meditation technique called Transcendental Meditation. The state is characterized by decreased oxygen consumption, carbon dioxide elimination, respiratory rate and minute ventilation, with no change in respiratory quotient. Arterial blood pH and base excess decrease slightly while arterial blood lactate markedly decreases. Systolic, diastolic, and mean arterial blood pressures remain unchanged. The electroenceph […]

In the Western world today, there is a growing interest in nonpharmacological, self-induced, altered states of consciousness because of their alleged benefits of better mental and physical health and improved ability to deal with tension and stress. During the experience of one of these states, individuals claim to have feelings of increased creativity, of infinity, and of immortality; they have an evangelistic sense of mission, and report that mental physical suffering vanish (Dean). […]

A wakeful hypometabolic state may be induced by simple, non-cultic mental techniques or by traditional meditational practices. The hypometabolic state seems to represent an integrated hypothalamic response ("relaxation response") which is consistent with a state of decreased sympathetic-nervous-system activity. A prospective investigation was designed to test whether regular elicitation of the relaxation response might lower blood-pressures in hypertensive patients who were maintained […]

Mental states can markedly alter physiologic function. Hypermetabolic physiologic states, with an increased oxygen consumption, accompany anticipated stressful situations. Hypometabolic physiologic changes, other than those occurring during sleep and hibernation, are more difficult to produce. The present investigation describes hypometabolic and other physiologic correlates of a specific technique of meditation know as "transcendental meditation". Thirty-six subjects were studied, ea […]

Background Transcendental meditation (TM) is a stress reduction technique that can potentially lower blood pressure (BP) safely. The American Heart Association recommends that TM may be considered in clinical practice. Objective To provide an overview of all systematic reviews and meta-analyses of TM on BP for evidence-informed clinical decision making. Method Systematic searches of PubMed, EBSCOhost, Cochrane Library, Web of Science, Embase, and PsycINFO for all systematic rev […]

A prospective investigation was designed to test whether the altered behavior of the regular practice of a relaxation, meditational technique might lower blood pressure in 22 borderline hypertensive subjects. The investigation was unbiased with regard to the presence of antihypertensive agents; subject familiarity with blood pressure measurement or with the observer; observer error; and the effects of blood pressure variability. During the control period, blood pressures averaged 146. […]
