Essential oils reduce cortisol levels

Research based evidence showing essential oils reduce cortisol levels.

Recent studies shed light on the potential of pure essential oils to impact physiological parameters like cortisol levels, which are often associated with stress and hormonal balance. We already knew this - but it's nice to have some science based evidence!!

A comprehensive systematic review involving 34 studies examined the effects of aromatherapy on menopausal symptoms, perceived stress, and depression in middle-aged women. This meta-analysis found that aromatherapy massage was effective in reducing menopausal symptoms and stress when compared to control groups. Notably, jasmine oil was highlighted for its ability to control salivary cortisol levels, among other essential oils such as rose, lavender, basil, peppermint, tea tree, ylang-ylang, rose geranium, grapefruit, cypress, rosemary, eucalyptus, chamomile, and geranium, which were found to alleviate depression and manage stress. Clary sage, neroli, and jasmine, in particular, were noted for their effects on stress and hormones, with studies reporting decreased cortisol levels and improved mood with the inhalation of clary sage oil. Neroli oil was found to positively affect menopausal symptoms, stress, and estrogen levels, while jasmine oil showed a physiological and psychological effect by increasing alertness and a sense of well-being​.

Another significant piece of research conducted by the International Federation of Aromatherapists (IFA) focused on the long-term impact of essential oils on chronic stress. This pioneering study aimed to establish empirical evidence of the effectiveness of essential oils over an extended period, rather than just a short-term decrease in stress levels. The study involved two protocols: a laboratory-based study with 100 participants over 8 weeks to test cortisol levels using saliva samples, and a 'live' study where volunteers used the oils at home, with hair samples taken at the beginning and end of the study to measure cortisol. The results suggested that daily inhalation of essential oils could help maintain lower cortisol levels throughout the day, leading to improved sleep quality and a more refreshed awakening.

These findings highlight the potential of essential oils as a natural, non-invasive means of managing stress and balancing hormones, contributing to the growing body of evidence supporting the therapeutic use of aromatherapy. However, it's important to note that these studies are specific to the context and populations in which they were conducted, and further research is always needed. :)
