Laughter is the best medicine! Laughter Yoga is the practice of combining laughter exercises with yogic breathing. The many benefits of laughter include: lowering the negative effects of stress, oxygenating the body and brain, and improving mood and overall health. The concept of Laughter Yoga is based on a scientific fact that the body cannot differentiate between fake and real laughter if done with willingness. One gets the same health benefits, whether laughter is real or simulated. It was started by a medical doctor, Dr. Madan Kataria, in India in 1995. There are thousands of Laughter Clubs in more than 106 countries!
