【摘要】
大量實證研究證實自然能帶給人們正向的心理效益，然而鮮少以
「接觸自然時間長短」的角度切入。本研究結合智慧型手機，連續記錄7日
受測者日常生活環境中「與自然接觸之劑量」，試圖探討接觸自然時間長
短、知覺自然度與產生之情緒反應。結果顯示接觸自然時間長短呈現倒U
字型曲線的趨勢：在接觸61-90分鐘呈現最佳的正向情緒狀態，之後接觸時
間越長，情緒狀態越趨於平緩或下降，然而接觸151-180分鐘情緒反應有上
升趨勢；受測者知覺到的自然度越高，越能獲得正向情緒。本研究驗證每
日生活環境接觸自然對情緒有影響，未來應進一步使用穿戴式裝置收集生
理數據，更有助於分析與自然接觸時間之質與量對生心理反應，作為每日
接觸自然時間劑量之參考指標。
Increasing empirical research has confirmed the positive
psychological effects of nature on human beings. However, limited studies have
discussed the impact of daily exposure to nature. Employing a smartphone to
record the daily impact of exposure to nature continuously over a seven-day
period, this study examined the duration of exposure, perceive naturalness,
and emotional condition using the Zuckerman inventory of personal reactions
(ZIPERS) scale. The results showed that the relationship between emotion
and exposure time formed an inverted U-shaped curve. The strongest positive
emotional state was observed for the duration of 61–90 minutes, following
which the effect of nature tended to weaken. During the 151–180 minutes, the
exposure-response curve sloped upward. In addition, the higher the perceived
naturalness, the more positive the emotional responses were. This study clarified
the relationship among contact time, naturalness, and psychological responses. It
also verified the benefits of daily exposure to nature or greenery. Future research
could further examine physiological data obtained from wearable devices as well
as surrounding environment and natural elements to provide more insight into the
impact of daily exposure to natural landscapes.
