All young women with a Premenstrual Syndrome Scale total score of 110 and above will be included in the study. Since all women who have a Premenstrual Syndrome Diagnostic Scale of 110 and above, volunteer to participate in the study and meet the inclusion criteria will be included in the study, no additional sample selection will be made. The application and control group will be determined on random.org among the group that constitutes the sample of the study. Laughter therapy sessions will be administered face to face to the application group once a week for 2 months by a researcher with a laughter therapy certificate. At the end of two months, the Personal Information Form, Premenstrual Syndrome Scale, and the Food Craving Scale will be administered again to both the application group and the control group.
