Laughter and positive therapies: modern approach and practical use in medicine

The exploration of the possible strategies centered in positive emotions is a suggestion to investigate and probably useful to raise the efficiency of therapeutic interventions. Laughter and humor have been classified as part of the 24 personal strengths and are considered as one of the activities that encourage personal well-being, savoring, and promoting flow states. Laughter therapy, classified within alternative or complementary therapies in medicine, includes a group of techniques and therapeutic interventions aimed to achieve laughter experiences which result in health-related outcomes, both physiological and psychological. Recent advent of positive psychology has developed high interest and expectations in the benefits of adding positive techniques to laughter therapy (and to other mind-body therapies). Consequently with this modern approach positive laughter therapy was born, as add-on to conventional laughter therapy and positive psychology, with its contributions and limitations. Health professionals can exert an important role in order to disseminate overall benefits of "positive therapies" while applying them in real-world clinical settings, for both patients and themselves.
