There is a growing body of research indicating that laughter may improve immune function, help lower blood pressure, boost mood and reduce stress and depression, the Washington Post reported on October 24 in a story entitled “Laughing may help ease blood pressure, boost mood and enrich health in other ways.” Robert Provine, professor of psychology, agrees. He said that laughter might benefit the body because it is “an energetic, stressful activity that stirs up all of our physiological systems… involving strong vocalization, an increase in heart rate and blood pressure and muscle contractions all over the body.”
