Hospital clowning, also known as "Clown Care", involves specially trained clowns visiting healthcare facilities. Clown therapy uses humor to promote patient well-being by reducing anxiety and stress and improving emotional flexibility, self-esteem, and attitude. The first hospital clowns worked in the 1970s, and clown doctor programs now operate worldwide. A six-month clown care training program is available, and the career offers benefits like improved immune function and interactions for patients.
