O'Halloran et al., 1989

O’Halloran, J. P.; Jevning, R. A.; Wilson, A. F.; Skowsky, R.; and Alexander, C. N. Behaviorally induced secretion of arginine vasopressin. Departments of Medicine and Physiology, University of California at Irvine, Orange, California, USA; Department of Endocrinology, Long Beach Veteran’s Administration Hospital, Long Beach, California, USA; and Department of Psychology and Social Relations, Harvard University, Cambridge, Massachusetts, USA, 1983.

Plasma vasopressin levels were found to be elevated before, during, and after the practice of Transcendental Meditation compared to levels at other times of the day, and to levels in nonmeditating controls who rested. This effect was not due to the usual mechanisms responsible for vasopressin release, and may be of importance in mediating the benefits of Transcendental Meditation for learning, memory, and behavior. The meditators were also found to have lower state and trait anxiety scores before and after Transcendental Meditation, compared to the controls. Furthermore, galvanic skin resistance increased more markedly during Transcendental Meditation than relaxation.
