FULL ANSWER

1. Begin the session with warm-up exercises
   Yoga instructors instruct the participants to perform warm-up exercises, such as talking gibberish and tongue swindling, in order to express joy. Participants start off doing these exercises quietly, then increase the volume as they get more comfortable. People who practice laughter yoga alone often warm-up in front of a mirror.
2. Perform the laughter exercises
   There are several different laughter exercises a yoga instructor can use. The greeting laughter technique involves the participants walking around the room and greeting each other with a laugh. The argument laughter technique involves participants arguing with each other with laughter. Another technique, the heart laughter technique, has the participants laugh together as they hold hands or hug.
3. End the session with laughter meditation
   The session ends with 15 minutes of laughter meditation, which involves the participants breathing deeply and laughing when they feel like it. Gradually, the laughter winds down to a period of deep relaxation.(Hasyayoga) is a practice involving prolonged voluntary laughter. Laughter yoga is based on the belief that voluntary laughter provides the same physiological and psychological benefits as spontaneous laughter. Laughter yoga is done in groups, with eye contact and playfulness between participants. Forced laughter soon turns into real and contagious laughter.
   In the mid-1990s, laughter yoga was practiced in the early mornings in open parks, primarily by groups of older people. Laughter yoga was made popular^{[citation needed]} as an exercise routine developed by Indian physician Madan Kataria, who writes about the practice in his 2002 book Laugh For No Reason.^[1]The yoga is performed without any humorous reason to laugh, with one practitioner observing that "The mind does not know that we’re faking it."^[2]
   Laughter yoga sessions may start with gentle warm-up techniques which include stretching, chanting, clapping, eye contact and body movement, to help break down inhibitions and encourage a sense of playfulness. Breathing exercises are used to prepare the lungs for laughter, followed by a series of ‘laughter exercises’ that combine the method of acting and visualization techniques with playfulness. Laughter exercises are interspersed with breathing exercises.^[3] Twenty minutes of laughter is sufficient to develop full physiological benefits.
