Abstract

The use of scents in sleep medicine is gaining increasing attention since they have been shown to improve sleep quality. This randomized double-blinded crossover trial measured the extent to which a continuous nightly presentation of a synthetic jasmine scent combined with lavender oil and passionflower herb improves subjective and objective sleep quality. Thirty sensitive sleepers (ISI 7-14) who suffer from delayed sleep-onset and frequent sleep disturbances (2-3 per week) were monitored under four conditions in the sleep laboratory over four nights. The first night was for acclimation (baseline), and the other nights were randomized in a counterbalanced order (placebo rose scent, a high-dose of jasmine scent, or a low-dose relative to the essential oils). Alongside this, subjects were given standardized questionnaires to complete in the morning and evening. There was a significant improvement in sleep quality and total sleep time when using scents compared to baseline. Furthermore, both variants of jasmine decreased wake after sleep onset. The results also indicated that the application of scent on the T-shirt was well tolerated by all subjects. Overall, it was shown that the jasmine scent may positively affect sleep parameters, and moderators such as dosage, application method, and duration of the scent should be further investigated.
