Mann Whitney U-test was performed to determine the gender different of physiological and mood effect. Results Autonomic nervous system parameters The mean and Standard Deviation (SD) values of autonomic parameters in the experiment are presented in Table 2. The data were compared on various autonomic parameters during resting and inhaling sweet almond oil. Subjects had significantly decreased heart and breathing rates (p-value < 0.05) during the sweet almond oil treatment compared with those of resting. Moreover, when subjects inhaled the lavender the systolic and diastolic blood pressures, heart rate and skin temperature were significantly decreased compared with sweet almond oil inhalation. Mood state response The mean and SD of mood state response are shown in Table 3. Subjects felt unpleasant when sweet almond oil was applied, with data showing decreased scores in good, active, fresh and relaxed feelings. After a lavender inhalation, subjects felt they had significant increases in pleasant emotions; good, active, fresh, and relaxed (p-value < 0.05).
