Clinical research has supported the idea by showing positive physiological and emotional changes as a result from non-humor based laughter. A 2006 study by Laughter Yoga International conducted in Bangalore, India proved that laughter lowers levels of blood pressure, heart rate, cortisol, and perceived stress. Further research showed that non-humor based laughter increases positive emotions, self-awareness, and overall competencies (Beckman, Regier, & Young, 2007).
Laughter Yoga® helps lower the negative effects of stress, which is a catalyst for health problems. Conversely, laughter lowers blood pressure, relaxes muscles, improves blood circulation, increases oxygen levels in the body, elevates mood, brings hope, and boosts the immune system, all of which are essential parts of maintaining good health.
