Outline of Final Research Achievements

It has been reported that brief exposure to nature-derived stimuli in experimental settings, such as plant odors, generally elicits a sedative physiological response. In this study, we aimed to examine the effects of nature-derived stimuli in the daily lives of healthy young adults living in urban areas (at rest/during normal times). The results showed that the introduction of nature-originated materials and odors reduced stress and chronic fatigue and had a relaxing effect, but also suggested the possibility of “habituation” to the stimuli. Due to the COVID-19 situation, issues remain regarding the investigation of human adaptation to artificial environments.

Academic Significance and Societal Importance of the Research Achievements

森林浴や植物の香りなど「自然」との触れ合いによる鎮静的な生理反応は、「現代人は人工環境下において常に生理機能が緊張状態にあり,自然に触れると緊張のため上昇した状態にあった血圧や心拍数が低下する」との仮説で説明されている。本研究は人工環境下に生きる人の生活の場における自然由来の材料やにおいの影響を調査することで、この仮説の検証を従来の実験室における実験とは異なる面から行おうとしたものである。
