Brief Summary

Today, psychophysiological insomnia is the most common persistent insomnia. Lavender essential oil is frequently used in the literature as an aromatherapy method to improve sleep quality. Studies have found that lavender improves sleep quality. They also emphasized that more studies are needed in this area. When the relevant literature is reviewed, no studies examining the effects of lavender oil on patients with psychophysiological insomnia were found. In this context, the aim of the study was to evaluate the effect of lavender on sleep quality and insomnia severity in patients with psychophysiological insomnia.
