Laughter Yoga is a unique exercise routine which combines unconditional laughter with yogic breathing (Pranayama). Anyone can laugh without relying on humor, jokes or comedy. Laughter is initially simulated as a physical exercise while maintaining eye contact with others in the group and promoting childlike playfulness. In most cases this soon leads to real and contagious laughter. Science has proved that the body cannot differentiate between simulated and real laughter. Laughter Yoga is the only technique that allows adults to achieve sustained hearty laughter without involving cognitive thought. It bypasses the intellectual systems that normally act as a brake on natural Laughter.
