Differences in Physiological Effects of Aromas : Study with EEG Analysis

(Research Paper,The 31st Symposium 31st Symposium on Life Information Science)

Abstract

The effects of aromas were discussed by analysis of fatigue reduction effects and by physiological effect differences of various aromas, based on EEG alpha waves as the indicator of relaxation. Among the aromas for this study, grapefruit aroma showed refreshing and relaxing effects and Japanese cherry birch (Mizumezakura) aroma, whose main component is methyl salicylate showed a sedative relaxing effect. The cherry birch was considered to be effective for fatigue reduction after participation in sports.
