Abstract

芳香のセラピー効果の判定には,主観的な感情による評価と客観的な生理的効果の両面から確認する必要がある.私たちは,クレペリンテストを45分間負荷した後,カモミール茶(または同量・同温の白湯)を飲ませ,自律神経機能(心電図R-R間隔データと体温)と感情指標(質問紙MCLによって測定した快感情,リラックス感,不安感)の変化を同時に測定した.カモミール茶を飲んだ後にリラックス感得点が上昇した.一方,自律神経機能では心拍数と交感神経活動の指標とされるLF/HF比の低下が大きく,末梢皮膚温の上昇が大きかった.カモミール茶を飲んだ後のリラックス感得点の変化量と自律神経機能の変化量の間に,有意な相関が認められた.これらの結果から,客観的に評価される生理指標の値と主観的な感情得点がかなり良く対応すると考えられる.

Physiological and psychological evaluations are both necessary in order to judge the effects of aromatic substances. We measured the both changes in autonomic nervous system parameters (i.e. heart rate R-R intervals data and skin temperature) and mood scores (i.e. pleasantness, relaxation and anxiety) following drinking chamomile tea (or hot water of same volume and temperature as chamomile tea) after 45 min Kraepelin test. Scores of relaxation increased after drinking chamomile tea. Decrease of heart rate and LF/HF ratio, an indicator of sympathetic nervous activity, were greater after drinking chamomile tea than hot water. Elevation of peripheral skin temperature was higher after drinking chamomile tea than hot water. Significant correlation was observed between changes in relax scores and autonomic nervous system parameters after drinking chamomile tea. From the results, it became obvious that the objective physiological parameters fully correlated with the psychological indices reported subjectively using the standardized questionnaire.
