Practically relevant stress relieving effects of olfactory stimuli delivered by a specially formulated odour inhaler (AromaStick®): Overview of an initial series of studies testing different boundary conditions. International Journal of Clinical Aromatherapy, 11, 48-58.
Abstract: A series of studies was designed to investigate the effects of direct application of odours (using a nasal inhaler) in relieving stress. In order to see whether odour inhalers had any practical use, this method was compared to popular stress-relieving interventions. Results showed a consistent pattern of success with a pronounced, measurable impact on stress-related physiological parameters (heart rate, blood pressure and cortisol levels) and mood, pointing to the practical relevance of this method of aromatherapy.
