Laughter-inducing therapies are being applied more regularly in the last decade, and the number of scientific reports of their beneficial effects is growing. Laughter-inducing therapies could be cost-effective treatments for different populations as a complementary or main therapy. A systematic review and meta-analysis has not yet been performed on these therapies for different populations and outcomes, but is needed to examine their potential benefits. This research aims to broadly describe the field of laughter-inducing therapies, and to estimate their effect on mental and physical health for a broad range of populations and conditions.
