Breathe In Cedar Wood, Breathe Out Stress


The aroma of essential oils has been investigated to improve wellness in a work environment.

Mentality is not the only target of stress, however. According to Katerina Steventon, Ph.D., FaceWorkshops LLC East Yorkshire, U.K., skin is sensitive to psychological stress and its appearance is affected by health and well-being.

A Whiff of Inspection

A recent study examined the effects Japanese cedar wood essential oil (Cryptomeria japonica) has on salivary dehydroepiandrosterone sulfate levels after tedious work. ScienceDirect highlighted that the salivary markers may therefore serve as a tool to detect the effects of aroma perception. 

The experiment consisted of one room with diffusion of the essential oil and one room without it. The study had participants sit facing a wall and fill out a questionnaire for an understanding of their odor assessment. Participants’ saliva were collected before and four times after they had performed arithmetic work.

Sniffing Out a Solution

The study found inhaling air with volatile compounds of Japanese cedar wood essential oil increased the secretion of dehydroepiandrosterone sulfate. Therefore, this essential oil is proven to improve the mental health and stress responses of employees. With improved mental health, skin's health improves as well.

Fragrance plays a role in brain activity and the sympathetic and parasympathetic nervous system in addition to the neuroendocrine system, neurotransmitters and neuromodulators, said Steventon. This influences psychological behavior and body function.

“… the olfactory system plays a role in central nervous system function beyond that of smell, influencing stress biomarkers, oxidative stress, estradiol, dopamine, skin barrier function, sebum secretion and skin immune system,” explained Steventon.

Air Care Solution

This research suggests Japanese cedar wood essential oil could have a potential in product development for air and home care. From sprays to candles to digital scent messaging, combining sensory research with product innovation can offer new ways to experience scent for consumers who are looking for multifunctional products.

The global air care market is expected to reach US $11.71 billion by the end of 2021. From a regional perspective, Asia Pacific (APAC) is expected to lead the air care market by 31.7%. As a result of growing populations, a rise of disposable income and an increase in product awareness, APAC will take a significant lead over the the current air care market holder, Europe.
