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.
