Laughter yoga is a unique practice that combines intentional laughter with deep yogic breathing to promote physical, mental, and emotional well-being. Developed by Dr. Madan Kataria in 1995, it encourages group laughter exercises, playful activities, and mindfulness to reduce stress and boost happiness. Unlike humor-based laughter, laughter yoga uses voluntary laughter that quickly becomes genuine through eye contact and childlike playfulness. The practice increases oxygen supply, improves mood, strengthens the immune system, and promotes relaxation. It can be practiced by people of all ages and does not require special equipment or experience, making it an effective and joyful wellness activity.
