Does Aromatherapy Have Therapeutic Effects on Chronic Stress?

May 2, 2024

Aromatherapy has been in use for centuries for a myriad of health benefits. It’s a holistic healing treatment that uses natural plant extracts, known as essential oils, to promote health and wellbeing. Over time, researchers have turned their attention to the potential benefits of aromatherapy for managing stress and anxiety. This article delves into the therapeutic effects of aromatherapy on chronic stress, with a focus on scholarly articles from reputable databases like Google Scholar, Crossref, and PubMed.

The Science Behind Aromatherapy

Before we delve into the effects of aromatherapy on stress, it’s crucial to understand its underlying mechanism. Essential oils, the primary agents in aromatherapy, are volatile compounds extracted from plants, each carrying distinct therapeutic effects.

When inhaled, the molecules of these oils interact with the brain’s limbic system, a region associated with emotion, memory, and arousal. These interactions can potentially influence physiological parameters like heart rate, stress levels, blood pressure, breathing, and the immune system.

A study available on PubMed (doi:10.1016/j.jep.2005.05.017) shows that the inhalation of lavender essential oil, for example, can decrease heart rate and blood pressure in the short term, thereby promoting relaxation.

Aromatherapy and Stress Relief – What Do Studies Say?

Several studies have been conducted in recent times to examine the therapeutic benefits of aromatherapy for stress, anxiety, and other related symptoms.

A study from Google Scholar (doi:10.1089/acm.2006.12.639) examined the effects of aromatherapy on music students’ performance stress. The study found that students who inhaled bergamot essential oil had lower stress responses and improved performance.

Similarly, a study available on Crossref (doi:10.1016/j.jep.2005.05.017) found that aromatherapy effectively reduced the stress response in rats. The rats, subjected to a maze test under the influence of lavender essential oil, exhibited reduced anxiety-like behavior. While animal studies do not translate directly to humans, they offer valuable insights into potential mechanisms of action.

Lavender Essential Oil: The Stress-Busting Champion

Many essential oils have been studied for their potential benefits on stress and anxiety. Among them, lavender essential oil stands out as the most widely researched for its calming and stress-relieving properties.

In a study available on PubMed (doi:10.1016/j.tmaid.2007.10.005), lavender oil’s inhalation was found to have a significant statistical decrease in the anxiety and stress levels of patients awaiting dental treatment.

Another study on Google Scholar (doi:10.1016/j.phymed.2006.08.008) revealed that patients in an intensive care unit exhibited reduced anxiety levels and improved sleep quality after lavender oil aromatherapy.

Is Inhalation the Best Method of Use for Aromatherapy?

When it comes to aromatherapy, various application methods are available, each having its unique benefits. However, studies seem to lean towards inhalation as the most effective way when addressing stress and anxiety symptoms.

Inhalation allows the molecules of essential oils to travel directly to the brain, offering immediate effects. As stated in a study on Pubmed (doi:10.1177/1534735403256419), the inhalation of lavender essential oil led to significant reductions in blood pressure, heart rate, and skin temperature, which are physiological responses to stress.

It’s also worthy to note that inhalation of essential oils has relatively fewer side effects when compared to other application methods, making it a safe and efficient method of use.

A Word of Caution

While the evidence supporting aromatherapy’s therapeutic effects on chronic stress is compelling, remember that it might not work for everyone. It’s also essential to use these oils correctly and safely.

If you’re considering essential oils for stress relief, you should first consult a healthcare provider, especially if you have allergies, asthma, or other health conditions. Additionally, essential oils should never replace any prescribed treatments for chronic stress or anxiety.

Randomized Controlled Studies on Aromatherapy

In the realm of scientific studies, randomized controlled trials (RCTs) are the gold standard for testing the efficacy of treatments. RCTs involve randomly assigning participants to either a treatment group or a control group, reducing bias and enhancing the reliability of results.

In one such RCT, available on Crossref (doi:10.1080/00207450601042094), researchers assessed the effects of aromatherapy on 56 individuals diagnosed with depression. The study found a significant improvement in sleep quality and a reduction in depression scores among participants who received aromatherapy compared to the control group without any adverse side effects.

Another RCT on PubMed (doi:10.1155/2013/381381) involved 50 patients suffering from chronic anxiety disorders. The study found that those exposed to lavender essential oil reported significantly lower anxiety levels and better mental health status than the control group.

While more large-scale RCTs are needed to conclusively establish the therapeutic benefits of aromatherapy, these studies provide robust preliminary evidence of the potential of essential oils in managing chronic stress and related conditions.

Aromatherapy Massage: A Potent Combination

While inhalation is the primary method of using essential oils, another common application is through aromatherapy massage. This method combines the benefits of massage therapy, such as muscle relaxation and improved circulation, with the therapeutic effects of essential oils.

A study available on Google Scholar (doi:10.1080/00207450601042094) found that aromatherapy massage significantly reduced blood pressure in women going through menopause.

Another study available on Crossref (doi:10.1080/00207450601042094) found that aromatherapy massage could effectively alleviate the psychological and physical symptoms related to occupational stress.

These findings suggest that aromatherapy massage could be a viable option for individuals who prefer a more hands-on approach to stress management.


The body of research on the therapeutic effects of aromatherapy on chronic stress is continually growing, with evidence pointing towards its potential efficacy. Essential oils, especially lavender oil, have shown promising results in reducing stress and anxiety and improving sleep quality in various studies. Moreover, inhalation appears to be the most effective method of using these oils, although aromatherapy massage also exhibits potent benefits.

While the results from the studies mentioned above are encouraging, it’s crucial not to overlook the importance of safe and correct usage. Essential oils should be used as a complementary therapy rather than a replacement for prescribed treatments. Always consult a healthcare provider before incorporating aromatherapy into your stress management routine.

The therapeutic journey of aromatherapy is exciting and could open new dimensions in the realm of natural, holistic healing. As we continue to explore this path, we must always remember to tread with caution, respecting the potent power these oils hold within their delicate drops.
