Scientists and medical doctors now agree that laughter ( láp tờ) can help people deal with stress and anger (êng gờ). Laughter yoga is a series ( si riz) of exercises which teaches you to laugh for no reason. When you do laughter yoga in a group, you laugh (laf) and do yoga breathing, so that you increase the amount of oxygen (ˈäksəjən) in your body. Soon the laughter exercises turn into real laughter. After a laughter yoga class, you feel calm (kam) and relaxed, but also happy and full of energy. Laughter yoga was developed by a medical doctor, Dr Madan Kataria. He started the first laughter yoga classes in 1995 with just five people, and now there are over six thousand laughter clubs in sixty different countries.
