Abstract

Negative ion is considered as one of the forest health attributes. The overall purpose of this study was to investigate the influence of air negative ions on physiological effects. Data were collected from 12 volunteers (university students) who were randomly assigned into treatment and control groups. Subjects in treatment group were exposed to air with negative (2,001,000 ion/cc). Using pretest-posttest control group design, blood cortisol, norepinephrine, epinephrine, and cognitive function were measured. Data analysis indicated that negative ions influenced on positive effects of stress responses.

산림의 건강 기능은 여러 인자에 의하여 수행된다. 본 연구는 산림의 건강물질 중의 하나라고 알려진 음이온의 건강 효과를 알아보기 위하여 수행되었다. 본 연구는 12명의 대학생집단을 피험자로 하여 실험군과 비교군으로 무작위 할당한 후 실험을 진행하였다. 실험군에 속한 피험자들에게는 음이온 (2,001,000 ion/cc)에 노출시키고 인지능력 테스트와 생리적인 변화의 측정을 위하여 채혈을 실시하였다. 자료의 분석결과 음이온에 노출된 실험군에서는 비교군에 비하여 긍정적인 생리적 변화가 발견되었다.
