Objective: This study aimed to evaluate the effect of Lavandula angustifolia essential oil inhalation on sleep and menopausal symptoms in postmenopausal women with insomnia. Methods: In this double-blind, randomized controlled trial, 35 women (aged 48-65) with a clinical diagnosis of insomnia were divided into two groups: Placebo, which inhaled sunflower oil before bed and Aroma, which inhaled Lavandula angustifolia essential oil before bed, for 29 days. Both groups received sleep hygiene guidelines before the intervention and weekly follow-up during it. Polysomnography and validated questionnaires, such as Epworth Sleepiness Scale, Insomnia Severity Index, and Pittsburgh Sleep Quality Index were used to evaluate sleep. In addition, the effect of the intervention on quality of life, anxiety and depression symptoms, and postmenopausal symptoms were assessed. Evaluations were performed before and after intervention in both groups. Statistical analyses were performed with SPSS 22 using the Generalized Estimated Equations test and intention-to-treat to impute missing data. Results: There were no significant differences between groups after intervention in the primary outcome; however, a tendency of improvement in wake after sleep onset (WASO) was observed. Both groups presented better sleep quality over time. Aroma group participants showed a significant decrease in sleep onset latency, depression levels, hot flashes, postmenopausal symptoms and, in polysomnography data, increased sleep efficiency (P=0.002) compared to baseline. Conclusion: Although no significant differences were observed between groups, our data presented a tendency of improvement in WASO. Moreover, Aroma group participants had enhanced overall sleep pattern, quality and sleep efficiency. Weekly follow-up and sleep hygiene instructions were essential for both groups to show improvement in almost all outcomes.
