These occupational demands may contribute to sleep disturbances and accumulated work stress, potentially affecting nurses’ health, work performance, and quality of patient care. Aromatherapy has increasingly been used as a complementary intervention for stress reduction and sleep improvement because of its noninvasive nature, low risk of adverse effects, and ease of administration. However, empirical evidence regarding its effects on work stress and sleep quality among ICU nurses remains limited.Purpose: This study aimed to examine the effects of aromatherapy on work stress and sleep quality among ICU nurses.Methods: An experimental research design was adopted. A total of 73 nurses were recruited from adult intensive care units at a medical center in Taichung, Taiwan. Participants were randomly assigned to an experimental group or a control group using pre-coded, sealed, opaque envelopes. The experimental group received aromatherapy using lavender essential oil and an aroma diffuser stone before bedtime for 1–2 hours daily over a four-week period, whereas the control group maintained their usual sleep routines without any intervention. Both groups completed the Nursing Staff Stress Scale and the Chinese version of the Pittsburgh Sleep Quality Index (CPSQI) before and after the intervention to evaluate the effects of aromatherapy on occupational stress and sleep quality. Data were analyzed using descriptive statistics, linear regression analysis, paired-samples t-tests, and generalized estimating equations (GEE). GEE was used to examine the group-by-time interaction to determine the effectiveness of the aromatherapy intervention. Results: Work stress scores decreased significantly in the experimental group following the intervention; however, GEE analysis showed that the group-by-time interaction was not statistically significant (β = −9.75, 95% CI [−27.35, 7.84], p = .277), indicating no significant difference in the magnitude of change in work stress between the experimental and control groups. For sleep quality, the CPSQI global score significantly decreased in the experimental group following the intervention. Moreover, GEE analysis revealed a statistically significant group-by-time interaction (β = −1.36, 95% CI [−2.52, −0.20], p = .022), indicating that the improvement in sleep quality was significantly greater in the experimental group than in the control group.Conclusions and Recommendations: The findings indicate that lavender aromatherapy significantly improved sleep quality among ICU nurses compared with the control condition. Although work stress decreased significantly within the experimental group, the magnitude of change did not differ significantly between the experimental and control groups. Future studies with larger sample sizes and longer intervention periods are recommended to further evaluate the effects of aromatherapy on work stress and the sustainability of its effects on sleep quality. These findings may provide a reference for the development of health promotion strategies for ICU nurses.工作壓力重症護理人員芳香療法睡眠品質work stressintensive care unit nursesAromatherapysleep qualitythesis
