In this captivating video clip, cardiologist Herbert Benson leads actor Alan Alda through the “relaxation
response,” a simple technique of sitting in a comfortable position, with closed eyes and relaxed muscles, while
slowly breathing and repeating a focus word such as “calm.”
Within minutes, Alda’s muscle tension decreases dramatically, illustrating how the mind can produce
stress-reducing benefits. Benson’s research studies have focused on the remarkable feats of Tibetan monks as they
practice Tummo yoga, including raising the temperature of their extremities by as much as 15 degrees. Benson
explains that meditation counteracts the vasoconstriction triggered by the stress hormones of the fight-or-flight
response, opening capillaries and increasing blood flow.
