버가못 향을 흡입한 젊은 여성들의 감성 및 뇌파 반응

Abstract

In this study, we evaluated the scent intensity, emotional response, and EEG response according to the concentration of bergamot scent inhaled by young women whose average age was 18, and analyzed the correlation between these factors. The correlation between bergamot concentration (P, vol %) and odor intensity (I) was [I] = 1.22 + 0.86P (r2 = 0.99). The scent intensity of bergamot was about 3.8. The emotional response to the scent of bergamot was rated as pleasant, fresh, refreshing and feminine. Inhaling bergamot decreased the α waves in the brain and increased the θ, β, and γ waves. Additionally, the edge frequencies of the SEF50 and SEF90 were increased by 0.14 Hz to 0.59 Hz and 0.75Hz to 1.26 Hz respectively by bergamot. The odor intensity (concentration) and emotional response regarding bergamot showed a weak correlation with the amount of change in the edge frequency (ΔSEF50 and ΔSEF90). These results suggest that bergamot is a refreshing, feminine fragrance with an arousing effect that activates the brain.
