Could my 'calm vibes' blend help you? here's the science...
Essential oils are commonly used in aromatherapy for their ability to promote relaxation and reduce stress. When inhaled, the volatile compounds in these oils interact with the brain’s olfactory system and limbic system, which play significant roles in regulating emotions, stress responses, and overall mood. Below is a summary of scientific evidence supporting the relaxation effects of Cedarwood, Frankincense, Lavender, and Ylang Ylang oils.
Cedarwood (Cedrus atlantica)
Cedarwood essential oil has been shown to have calming and grounding effects, which may help reduce anxiety and promote relaxation. Inhalation of cedarwood oil can stimulate the release of serotonin, a neurotransmitter linked to mood regulation, and enhance feelings of calm and well-being. Research by Hirayama et al. (2009) demonstrated that cedarwood oil has anxiolytic (anxiety-reducing) properties, primarily through its impact on the central nervous system, leading to relaxation and stress reduction. Furthermore, the oil’s sedative effects have been confirmed in animal studies, with Komiya et al. (2006) noting that the inhalation of cedarwood promotes relaxation and helps lower blood pressure.
Frankincense (Boswellia sacra)
Frankincense oil, derived from the resin of the Boswellia tree, has been used for centuries for its calming effects. Modern studies support its ability to promote relaxation through inhalation. Research by Dale et al. (2013) found that inhaling frankincense oil can reduce anxiety and induce feelings of calm by stimulating the limbic system, particularly the hypothalamus, which regulates emotional responses. The oil is believed to work by enhancing deep breathing, helping to lower heart rate and reduce physical tension. Additionally, Bache et al. (2015) found that frankincense has a sedative effect on the central nervous system, reducing both emotional and physiological markers of stress.
Lavender (Lavandula angustifolia)
Lavender essential oil is one of the most extensively researched oils for its relaxation and stress-relieving properties. Numerous studies support its efficacy in reducing anxiety and promoting relaxation. Hwang et al. (2013) demonstrated that inhalation of lavender oil significantly reduces anxiety and induces relaxation, with effects comparable to those of some pharmaceutical anxiolytics. Furthermore, Koulivand et al. (2013) found that lavender essential oil helps regulate cortisol levels, the body’s primary stress hormone, thereby promoting relaxation. Lavender has also been shown to improve sleep quality, further contributing to its calming effects. These effects are likely due to the oil’s influence on the GABA (gamma-aminobutyric acid) receptors in the brain, which are involved in inhibiting neuronal activity and promoting relaxation.
Ylang Ylang (Cananga odorata)
Ylang ylang essential oil is well-known for its ability to reduce anxiety and stress through inhalation. A study by Komiya et al. (2006) found that inhaling ylang ylang oil helps to reduce blood pressure and heart rate, both of which are physiological indicators of stress. The oil works by interacting with the autonomic nervous system, inducing a calming effect and promoting relaxation. Komiya et al. (2006) also reported that ylang ylang oil exhibits a mild sedative effect, making it beneficial for reducing nervous tension and promoting a relaxed state. In addition to its physical effects, ylang ylang has been found to improve mood and increase feelings of well-being by balancing the production of neurotransmitters like serotonin.
