INTRODUCTION: Regarding the importance of anxiety management and improvement of the quality of sleep in patients with burn injuries, this study aimed to determine the effect of aromatherapy massage (using aromatic oils of lavender and chamomile) on the anxiety and sleep quality of the patients with burn injuries. METHOD: In a quasi-experimental study, 105 patients with burns were recruited by convenience sampling method and then assigned into three groups (control, placebo massage, and combined aromatic oil massage). The study intervention was performed 20min before bedtime in three sessions, within a week. The control group was only under daily routine care. The study data were collected using the Persian version of Spielberg's anxiety scale and the Pittsburgh Sleep Quality Inventory. Descriptive and inferential statistical tests were used to analyze the data in SPSS version 20. RESULTS: The results showed a significant difference among the three groups in terms of anxiety score (P<0.001) and in terms of sleep quality after the intervention (P=0.027). CONCLUSION: Since the aromatherapy massage as a non-pharmacological and simple method can improve the anxiety and quality of sleep in patients with burns, it is suggested that nurses and burn medical care team apply it to reduce burn patients' anxiety and promote their sleep quality. Applying massage alone also reduces anxiety in burn survivors.
