World Laughter Day
Sunday, May 3, 2026
A park bench experiment. On March 13, 1995,Dr. Madan Kataria, a family physician in Mumbai, gathered four neighbors at Lokhandwala Park to test whether group laughter could deliver health benefits without humor. The initial approach relied on joke-telling, but the group quickly ran out of appropriate material. Kataria pivoted to a new method: participants would simply laugh together on purpose, combining sustained laughter with yogic breathing exercises called pranayama
