    Summary
    This summary is machine-generated.

    Autogenic training (AT) and transcendental meditation (TM) significantly lowered cortisol and prolactin levels. Both practices, unlike rest, reduced urinary catecholamines, suggesting stress reduction.

    Area of Science:

    • Psychoneuroendocrinology
    • Mind-Body Medicine

    Background:

    • Stress impacts physiological markers like cortisol, prolactin, and catecholamines.
    • Mind-body interventions are explored for their potential to counteract stress responses.

    Purpose of the Study:

    • To investigate the effects of autogenic training (AT) and transcendental meditation (TM) on stress-related biomarkers.
    • To compare the physiological impact of AT and TM against a control group.

    Main Methods:

    • 30 subjects were divided into three groups: AT, TM, and control (10 each).
    • Plasma cortisol and prolactin levels, along with urinary catecholamines, were measured over 40 minutes.
    • Physiological responses during rest were compared across the groups.

    Main Results:

    Related Experiment Videos

    • Both AT and TM groups showed decreased plasma cortisol and prolactin levels.
    • The transcendental meditation group exhibited significantly lower basal levels of cortisol and prolactin.
    • Urinary catecholamines decreased in AT and TM groups, while increasing in the control group.

    Conclusions:

    • Autogenic training and transcendental meditation appear to induce physiological changes opposite to those of stress.
    • TM demonstrated a more pronounced effect on reducing basal cortisol and prolactin levels.
    • These findings support the stress-mitigating potential of specific meditation and relaxation techniques.
