HUMAN RESPONSES TO FLOWER FRAGRANCE STIMULI OF DIFFERENT TIME DURATION
The effects of flower fragrance of rose (Rosa hybrid Escimo), lily (Lilium Siberia), violet (Matthiola incana), gardenia (Gardenia jasminoides) and lemon (Citrus limon) with 1 min, 3 min, and 5 min on human psycho-physiological responses were investigated in December 2008 at Beijing Forestry University. Physiological indexes of 30 undergraduates (15 males and 15 females), including blood pressure (BP), galvanic skin response (GSR), finger skin temperature (FT), fingertip pulse (FP), and oxygen saturation (OS), were measured after flower fragrance stimuli. The scores of state-trait anxiety inventory (STAI) and profile of mood states (POMS) were collected on behalf of the participants psychological reactions. The results showed that fragrance stimuli of rose flower for 1 min had more positive psychophysiological impacts than fragrance stimuli for 3 min and 5 min. The lily, gardenia and lemon flower fragrance stimuli for 5 min, and violet flower fragrance stimuli for 3 min increased significantly GSR and FT, and decreased BP and FP when compared with other stimuli time treatments separately. The results indicated that the stimuli time treatments of rose, lily and lemon flower fragrance mentioned above effectively reduced the subjects stress and anxiety. In conclusion, flower fragrance stimuli resulted in reducing participants stress, fatigue, and anxiety. Rose stimuli for 1 min, lily for 5 min, violet for 3 min, gardenia for 5 min, and lemon for 5 min are the most appropriate duration of stimulation time to study their physiological and psycho¬logical effects on human respectively.
