Abstract

This study analyzes the physiological healing effects on users according to forest types. Forest types are classified into Chamaecyparis obtusa, Quercus serrata and Pinus densiflora and the subjects of this study, 64 hypertensives, 59 diabetics and 59 ordinary people, were tested to observe their physiological effects. The index of physiological reaction comprises electroencephalogram(EEG), heart rate variability(HRV), blood pressure and cortisol level. An analysis of the stress-buffering effect from the physiological reactions of the overall subjects indicates that Quercus serrata forests have a higher stress-buffering effect than others in terms of central nervous, endocrine and autonomic nervous systems. Chamaecyparis obtusa forests are contributory to soothing stress in the central nervous and endocrine systems. Pinus densiflora forests contribute in some indexes of the endocrine and autonomic nervous systems. In contrast, Pinus densiflora forests are less influential on a stress-buffering effect than the other two. In the level of the effect for lowering blood pressure, Chamaecyparis obtusa and Quercus serrata forests are more effective than Pinus densiflora forests. Therefore, staying in the first two forests can heighten the healing effect of the lowering of blood pressure for hypertensive patients. Every forest is efficacious to lowering diabetic blood glucose levels. Spending time in Quercus serrata forests is more effective for hypoglycemic.

본 연구는 숲의 종류에 따른 이용자의 생리적 효과를 분석하기 위하여 실시하였다. 숲은 편백나무숲, 졸참나무숲, 소나무 숲으로 구분하고, 실험대상 집단은 고혈압 환자(64명), 당뇨병 환자(59명) 및 일반인(59명)으로 구분하여 생리적 반응을 측정하였다. 생리적 반응은 뇌파, 심박 변이, 혈압, 맥박, 코티졸, 혈압 등을 지표로 선정하였다. 전체 피험자의 생리적 반응으로 숲의 스트레스 완화효과를 분석한 결과, 졸참나무숲은 중추신경계, 자율신경계, 내분비계 측면에서 다른 숲에 비하여 높은 스트레스 완화효과를 기대할 수 있다. 편백나무숲은 자율신경계를 제외한 지표에서, 소나무숲은 내분비계와 자율신경계 일부 지표에서 스트레스 완화에 기여할 수 있다. 그러나 소나무숲은 스트레스 완화효과에 있어서 상대적으로 효과가 적다. 고혈압 환자는 효과의 정도 측면에서 소나무숲보다 편백나무숲과 졸참나무숲에서 체류할 때 높은 혈압 강하의 효과를 얻을 수 있다. 당뇨병 환자는 혈당저하의 효과측면에서는 모든 숲이 효과적이나 특히, 졸참나무숲에서 체류하는 것이 높은 효과를 경험할 수 있다.
