The idea of happiness is fundamental to mental health and influences several aspects of life. It is essential to consider the impact of persistent stress on individuals, particularly medical students. This study at Ayub Medical College aimed to evaluate factors influencing happiness among students. A cross-sectional survey was conducted with ethical approval, using stratified random sampling to select participants. Data was gathered through two questionnaires: the Oxford Happiness Questionnaire and another exploring additional factors. A total of 69 students participated, with an average happiness score of 4.01 ± 1.12. Results revealed that students who regularly engaged in physical activities, such as visiting the gym, reported higher happiness levels. Additionally, active involvement in social and religious organizations was linked to increased happiness. SPSS was used for data analysis. Also, people's happiness levels were much greater when they were actively involved in their social and religious organizations.
