Abstract
This mini-review examines the effectiveness of essential oils, such as lavender, chamomile, and valerian, in enhancing sleep quality. Addressing the growing prevalence of sleep disorders, this review analyzes research from 2020 to 2023, sourced from databases like PubMed and ScienceDirect. Findings show a notable positive impact of these oils across various groups, including postmenopausal women and palliative care patients. Lavender oil is highlighted for improving sleep efficiency and reducing nighttime awakenings. Chamomile oil, recognized for its calming properties, shows promise in managing sleep issues linked to anxiety disorders, though its efficacy in treating primary insomnia needs more exploration. Valerian oil, known for its sedative effects, has been effective in enhancing sleep and reducing anxiety. These oils' benefits are attributed to their influence on the nervous system, including anti-inflammatory and neuroprotective properties. The review points out the heterogeneity among studies and calls for more comprehensive research to understand these oils' mechanisms and identify the most effective types for sleep improvement. This research underscores the potential of essential oils as a natural, non-pharmacological option for treating sleep disorders, indicating a significant area for future investigation.
