This study characterized studies on aromatherapy and sleep quality and identified the measurable effects of aromatherapy on the sleep quality of adults and elderly people. Based on combined results of 30 included studies, the overall effect size for sleep quality improvement was statistically significant. Subgroup analysis assessed overall improvement based on country, study design, and type of intervention, with aroma massage therapy showing the largest effect. Significant combined effects of aromatherapy were also observed for stress, pain, anxiety, depression, and fatigue. Aromatherapy improves sleep quality and reduces stress, pain, anxiety, depression, and fatigue in adults and elderly people.
