Abstract

This study was conducted to investigate the effect of agarwood (Thymelaeaceae) inhalation using an electric incense burner on stress and brain waves. Sixteen participants were included in the study during the period from September 2019 to April 2020. Participant recruitment was undertaken by the 'H' center. This paper focused on stress reduction and compared the differences in stress and brain waves before and after agarwood inhalation using an electric incense burner. Electroencephalography was measured by a 19 Channel, Brainmaster Discovery, and analyzed using a NeuroGuide, LORETA (Brain Mapping). The analysis of technical statistics was carried out using SPSS/WIN 21.0 and the Wilcoxon signed-rank test. The study observed that the stress response index was reduced by a significance level of 0.01 in patients with anxiety, depression, and somatization disorders after agarwood inhalation. Secondly, alpha waves were increased by a significance level of 0.05, in 18 out of 19 regions measured, except FP 1. The difference after agarwood inhalation was the most significant in the region that affects emotion. Thirdly, a LORETA analysis found that alpha waves were increased in the brain region (BA 40) predominantly responsible for memory and emotion. This result clarifies that agarwood inhalation using an electric incense burner reduced stress and had a positive effect on brain waves and hence, has potential as an alternative therapy.

본 연구는 전기향로를 이용한 침향 흡입이 스트레스와 뇌파에 미치는 영향을 파악하기 위해 시행되었다. 'H' 발달센터 공고로 모집한 성인 남녀 16명 대상으로 2019년도 09월부터 2020년 4월까지 실시하였다. 전기향로에 침향편(沈香片)을 올려놓고 침향 흡입 전과 후의 스트레스 반응과 뇌파 측정을 비교 분석하여 침향 흡입이 스트레스 대처자원의 가능성을 알아보고자 하는 것이다. 뇌파 측정은 19 Channel, Brainmaster Discovery로 하였으며, 분석은 NeuroGuide와 LORETA를 사용하였다. 수집된 자료는 SPSS/WIN 21.0 프로그램으로 기술 통계, Wilcoxon 부호 순위 검정을 하였다. 결과는 첫째, 침향 흡입 후 스트레스 반응 지수는 분노, 우울, 신체화 모든 항목에서 유의수준 0.01로 유의미한 차이로 감소하였다. 둘째, 침향 흡입 후 뇌파에서 측정 부위 19곳 중에서 FP1 1곳을 제외한 18곳에서 Alpha Wave가 증가하였고, 유의수준 0.05에서 확인되었다. 감정에 영향을 주는 영역(우측 측두엽, T6)에서 침향 흡입 전과 후의 차이가 가장 크게 나타났다. 셋째, LORETA 분석 결과 침향 흡입 후 기억과 정서적 활동에 중요한 뇌 영역(BA40)에서 Alpha Wave가 증가하였다. 이러한 결과로 전기향로를 이용한 침향 흡입이 스트레스와 뇌파에 긍정적인 영향을 미쳐 스트레스 대처 자원이 될 가능성을 확인하였다.
