Laughter yoga combines breathing exercises, light stretches, and laughter to promote health benefits. Dr. Santosh Sahi leads sessions in Delhi's Lodhi Gardens, emphasizing laughter's physical, mental, social, and spiritual advantages. Originating in the 1990s, laughter yoga was founded by Dr. Madan Kataria to combat stress. Studies show laughter can improve heart health by affecting blood vessel function and reducing inflammation. Participants, like Manwar Singh Rawat, find social connection and stress relief through laughter yoga, which is also offered virtually worldwide.
