Aromatherapy has been practiced for thousands of years as a way to promote physical and emotional well-being. In recent years, research has provided evidence for many of the purported benefits of this ancient practice. In this blog post, we look at the health benefits of Aromatherapy and provide an evidence-based review of the scientific literature, including its effects on anxiety and depression, sleep quality, immune function, and pain relief.
Several studies have found that aromatherapy can help reduce symptoms of anxiety and depression. A 2018 study published in the Journal of Clinical Nursing found that aromatherapy massage using lavender oil helped reduce anxiety levels in patients with kidney disease undergoing hemodialysis. The study’s authors concluded that “lavender oil can be used as an effective intervention to reduce anxiety levels in patients undergoing hemodialysis.”
Another study published in the Journal of Alternative and Complementary Medicine found that a blend of lavender and bergamot essential oils was effective at reducing anxiety levels in patients undergoing cardiac catheterization. The study’s authors noted that “aromatherapy can be a cost-effective and noninvasive adjunct to the routine care of patients with cardiac disease.”
Aromatherapy has also been shown to improve sleep quality. A 2016 study published in the Journal of Korean Academy of Nursing found that inhalation of lavender essential oil improved sleep quality in patients with insomnia. The study’s authors concluded that “lavender inhalation could be recommended as an effective way to improve the sleep quality of patients with insomnia.”
Another study published in the Journal of Alternative and Complementary Medicine found that inhalation of a blend of lavender, marjoram, and neroli essential oils was effective at improving sleep quality in patients with coronary artery disease. The study’s authors noted that “aromatherapy using essential oils may be an effective nonpharmacologic intervention for improving sleep in patients with coronary artery disease.”
Aromatherapy may also have positive effects on immune function. A 2019 study published in the Journal of Ethnopharmacology found that inhalation of eucalyptus essential oil helped reduce symptoms of the common cold in patients with upper respiratory tract infections. The study’s authors noted that “the results of this study suggest that inhalation of eucalyptus essential oil can be used as a safe and effective treatment for the symptoms of the common cold.”
Another study published in the Journal of Alternative and Complementary Medicine found that inhalation of a blend of essential oils, including eucalyptus, thyme, and tea tree, helped reduce symptoms of the flu in patients with influenza-like illness. The study’s authors concluded that “aromatherapy using essential oils may have a positive impact on the management of symptoms of influenza-like illness.”
Aromatherapy has also been shown to be effective at reducing pain. A 2016 study published in the Journal of Clinical Nursing found that inhalation of lavender essential oil was effective at reducing pain in patients with primary dysmenorrhea, or painful menstrual cramps. The study’s authors noted that “aromatherapy with lavender essential oil is an effective treatment for primary dysmenorrhea and can be used as a safe and noninvasive alternative to pain medication.”
Another study published in the Journal of Korean Academy of Nursing found that massage using a blend of essential oils, including lavender, marjoram, peppermint, and ginger, was effective at reducing pain in patients with chronic lower back pain. The study’s authors concluded that “aromatherapy massage can be recommended as a nonpharmacologic intervention for managing chronic lower back pain.”
The scientific evidence suggests that aromatherapy can have numerous health benefits, including reducing symptoms of anxiety and depression, improving sleep quality, boosting immune function, and reducing pain. These benefits have been documented in numerous studies, with various essential oils demonstrating particular efficacy for certain conditions. For example, lavender oil has been shown to be effective at reducing anxiety levels, improving sleep quality, and reducing pain, while eucalyptus oil has been found to be effective at reducing symptoms of the common cold.
While more research is needed to fully understand the mechanisms behind these benefits, the evidence strongly suggests that aromatherapy is a safe and effective alternative or complement to traditional medicine. By incorporating aromatherapy into their daily routines, individuals can improve their physical and emotional well-being in a natural and non-invasive way.
As with any natural remedy or therapy, it’s important to consult with a qualified healthcare professional before using essential oils, particularly if you have any underlying health conditions or are pregnant. With proper use and guidance, however, aromatherapy can be a powerful tool for promoting health and wellness, and improving overall quality of life.
