For this study, the effects of lavender essential oil on the rate of relaxation after physical stress were investigated. While previous studies have been performed relating lavender aroma to decreased psychological stress, little data exists on the effect of lavender aroma on physical stress. Physical and mental stress share many of the same physiological effects including increases heart rate, respiration rate, and galvanic skin conductance. Due to these similarities it is probable that physical stress will reduce these values by comparable amounts to mental stress when lavender aroma is administered during recovery time. It was hypothesized that exposing subjects to lavender essential oil after moderate physical activity would decrease the recovery time for heart rate, respiration rate, and skin conductance to return to baseline, compared to control subjects not treated with lavender aroma. To test this hypothesis, the average recovery time and percent change of physiological vitals, including heart rate, respiration rate, and galvanic skin conductance between treatment groups were compared. From the results, no significant data was observed, therefore, it can be concluded that the presence of lavender does not have any appreciable effect on lowering heart rate, respiration rate and skin conductance after moderately intense physical activity, which the study used as indicators of physical stress.
