Evidence for the Effectiveness of Fragrances – Poised Aroma

Evidence for the Effectiveness of Fragrances

This blog post outlines 2 meta-analyses which showcase the efficacy of aromacology in improving mental and physical states. 

The data is clear, over 150 individual studies conclude different aromas produce different enhancements.

Aromas have been found to reduce anxiety and stress, increase confidence, enhance physical performance, improve cognitive productivity, induce relaxation, improve sleep quality, and even spark romantic arousal.

Study 1.

“The results indicated that various odours can significantly affect mood, cognition, physiology and behaviour.”

The first study looked at experiments which had to meet the following criteria: "(1) theory-guided goals and clear hypothesis testing, (2) fragrances are tested using appropriate experimental methodology, (3) sufficient and representative subject populations and appropriate contrasting control groups are used, (4) data are analyzed using suitable statistical methods, and (5) the results have been vetted by scientific peers and accepted for publication in reputable journals."

Some fascinating results were:

"Both male and female athletic college students exposed to peppermint oil in a patch on their upper lip experienced enhanced physical performance, specifically generating more push-ups and running faster (400m dash), compared to when they were exposed to an un-scented patch."

"Lavender decreased negative mood and arousal during a 20 min stressful situation compared to the stressor without lavender."

"Peppermint odour significantly reduced perceived workload and effort and increased self-evaluated physical performance."

"Both men and women undergoing a stressful procedure experienced decreased state anxiety, more positive mood and greater calmness when exposed to either orange or lavender oil in ambient air compared to no-odour or music."

"Lavender increased slow-wave-sleep and subjects reported higher vigour upon awakening compared to control."

Study 2.

"Based on the previous studies, it can be concluded that fragrances directly and/or indirectly affect the psychological and physiological conditions of humans. In addition, the electroencephalograph studies clearly revealed that fragrances significantly modulate the activities of different brain waves and are responsible for various states of the brain."

The second study reviews over 150 individual aromacology studies, and over 40 different scents. 

Some notable examples of the effects of individual fragrances are:

"The inhalation of jasmine oil increased the beta wave activity in the anterior center as well as the left posterior regions. These changes were associated with the increase of positive emotions such as the feeling of well-being, or feeling active, fresh and romantic."

"The results showed that the odour of Kouju may induce positive emotion. It may also affect the beta 1 activity at the right frontal region and improve memory task performance."

"Bergamot essential oil and synthetic oil relieved work-related stress of teachers with various workloads"

"The inhalation of eucalyptus oil effectively decreased the patient’s pain and blood pressure after total knee replacement surgery."
