This study investigated specific subjective or psychological effects of relatively long exposure to negative ions generated by a conventional air purification device. Subjects--24 males matched for age, education, physical condition, and smoking habits--were divided into a control (N = 12) and an ion exposure group (N = 12). The groups were subjected to 6 h normal and negatively charged atmospheres, respectively. The tests used were the Taylor Manifest Anxiety Scale (TMAS) and a self-report mood index. The analysis of TMAS change scores clearly showed no effect of negative ion exposure on anxiety. Analysis of mood index data showed significant changes in the subjective perception of both physiological state (relaxation increased) and psychological state (irritability, depression, and tenseness decreased while calmness and stimulation increased.
本研究调查了长时间暴露于传统空气净化设备产生的负离子所产生的特定主观或心理影响。研究对象——24名年龄、教育程度、身体状况和吸烟习惯相匹配的男性——被分为对照组（N = 12）和离子暴露组（N = 12）。两组分别在正常大气环境和带负电荷的大气环境中暴露6小时。使用的测试工具为泰勒显性焦虑量表（TMAS）和一份自我报告情绪指数。对TMAS变化分数的分析清楚地表明，负离子暴露对焦虑没有影响。对情绪指数数据的分析表明，生理状态（放松感增强）和心理状态（易怒、抑郁和紧张感降低，平静感和兴奋感增强）的主观感受均发生了显著变化。
