Purpose: To examine the effect of Benson's relaxation technique on occupational stress in midwives working in a Labor and Delivery (L&D) unit. Methods: This pre- and post-quasi-experimental study involved 65 midwives with a minimum 1 year of experience using convenience sampling. After training, the participants performed Benson's relaxation technique twice a day for 4 weeks. Results: Occupational stress was measured using standard questionnaires of occupational stress. Data were analyzed using the Statistical Package for Social Sciences software. Statistical analysis was performed using the Kolmogorov-Smirnov goodness-of-fit test, Student's t-test, and Wilcoxon signed rank test. Conclusion: This study demonstrated that Benson's relaxation technique may be effective in reducing occupational stress among midwives in L&D units.
