| Outline of Final Research Achievements |
This study aimed to confirm the effects of aroma compounds from different wood species. Evaluation indices of participants were changes in the cerebral blood flow determined using functional near infrared spectroscopy and subjective assessments of aroma compounds. The essential oil of five wood species, Hiba (Thujopsis dolabrata), Himekomatsu (Pinus pentaphylla)，Sawara (Chamaecyparis pisifera), Sugi (Cryptomeria japonica)，and Hinoki (Chamaecyparis obtusa) were used as experimental materials. We found that the inhalation of air containing aroma compounds emitted from Hinoki were subjectively preferred. Differences in temporal changes in the cerebral blood flow with the wood species were obvious, and aroma compounds emitted from Sawara and Hinoki were found to reduce the cerebral blood flow and Hiba were found to elevate. Therefore, we suggested that aroma compounds and their composition of wood species lead to different psychophysiological influences.
