World Laughter Day is celebrated annually on the first Sunday of May, promoting the healing benefits of laughter and raising awareness about community laughter clubs worldwide. Founded by Dr. Madan Kataria, this event encourages people to gather in large cities, public parks, and auditoriums to share laughter through various activities, including laughter clubs that often feature music, dance, and laughter contests. Participants engage in peace marches, chanting phrases like “Ho Ho, Ha-Ha-Ha,” and carry banners promoting community and wellness. The day emphasizes the health benefits of laughter, such as boosting the immune system, reducing stress hormones, and improving cardiac health. It also encourages individuals to learn to laugh at themselves and participate in activities like joke jars and comedy classes.
