General health is an important and pervasive issue for all society members, including students. Concerning the presence of various factors, university is a mentally stressful period. In this respect, commitment to religious beliefs and practical attachment to them can be considered an important factor in the prevention of mental traumas and in the improvement of health. The present study aimed to investigate the relationship between dimensions of religious practicing according to Islamic beliefs (RPAIB) and students’ general health. The study sample included 375 undergraduate students of Shahid Bahonar University who were selected using stratified random sampling. Tow questionnaires, including GHQ–28 and RPAIB, were administrated and analysed using Pearson correlation method and multiple regression analysis. Results showed that there was a significant relationship between GHQ and its dimensions and RPAIB and the dimensions related to it. Also, based on the results of the regression analysis, one dimension of RPAIB, i.e., commitment to conduction of religious behaviors (CCRB) could significantly predict general health. According to the results, it can be concluded that practical attachment to religious beliefs plays an important role in general health. Also, it can be considered as an effective factor for the students’ health in educational and preventive interventions in educational environments.
