Beneficial effect of laughter therapy on physiological and psychological function in elders

Abstract

AIM: In the present study we investigated the effect of laughter therapy on physiological and psychological function in older people. DESIGN: An open-label trial. METHODS: Seventeen older people who regularly attended an elderly day care centre were recruited. Stand-up comedy as laughter therapy was performed once a week for 4 weeks. Parameters of physiological and psychological function were evaluated before and after laughter therapy. RESULTS: Laughter therapy intervention resulted in a significant reduction in systolic blood pressure and heart rate, accompanied by a significant increase in plasma concentration of serotonin and a significant decrease in salivary concentration of chromogranin A. Questionnaire surveys of SF-8, GDS-15, and Vitality Index demonstrated alleviation of depression and improvement of sociability and activity in older people. Laughter therapy could be expected to become a practical treatment to improve quality of life of older people in an elderly day care centre.
