Brief Summary: Laughter is an innate, universal response we give to events in our lives. "Laughter Therapy" is a technique created by combining breathing techniques and laughter and takes its place in complementary medicine. It is a simulation performed by making eye contact with the members of the group, in which physical exercise and childlike games take place. Laughter sessions are about 30-40 minutes. continues and this simulation in a short time creates a real and contagious laugh. It has been determined by studies that laughter therapy physiologically increases breathing and relaxes muscles, strengthens mental function by decreasing the level of stress hormones, reduces burnout, depression and anxiety levels, positively affects quality of life, increases social interaction and provides psychological well-being.

Self-efficacy, on the other hand, is a state that expresses a person's belief that he or she is able to perform a certain task. More broadly, self-efficacy examines an individual's ability to perform a task rather than individual characteristics such as physical or psychological characteristics. Psychological well-being is as important as self-efficacy in the development of students. In addition, studies on mental health have generally focused on anxiety and depression. Most of these studies were related to well-being and contributed to the literature. Psychological well-being is defined as managing existential challenges in life.
