Aromatherapy is used for depression, anxiety, relaxation and disorders related with sleep and stress. A randomised controlled study was conducted with 60 patients to investigate the effect of lavender essential oil on the sleep quality and anxiety level of patients in coronary intensive care unit (ICU).
Study participants were administered a questionnaire, Pittsburgh Sleep Quality Index (PSQI) and the Beck Anxiety Inventory (BAI) scale. The patients in the intervention group were given 2% lavender essential oil via inhalation for 15 days after which they were administered the same scales again to evaluate the sleep quality and anxiety. As for the control group, they were administered the same scales again after 15 days without the inhalation of lavender essential oil.
Lavender essential oil increased quality of sleep and reduced level of anxiety in patients with coronary artery disease.
