In the month of July this year we conducted a pilot program with a group of employees from Hypercity - a shopping mall in Mumbai. This was to see if Laughter Yoga exercises could help improve sales and efficiency of those working at cash counters. Two batches of 50 people did Laughter Yoga exercises for 20 minutes every day 5 days in a week. The program was well received by participants as they wanted longer sessions of Laughter Yoga! In fact, many people who were not involved in the research program also joined in and enjoyed the laughter exercises. At the end of the program, there was a remarkable improvement in performance and participants reported high levels of well-being and life satisfaction. This study, which was organized by TRRAIN - a non-profit organization committed to help lower-middle-class sales and marketing people to improve their skills and knowledge, proved to be quite successful as seen by the results.
