A Preliminary Study on Influence of Anion Created by Anion-Fiber Used for Decorative Material on People's Physiology and Psychology

Article Preview

Abstract:

This study was conducted to examine whether negative air ions created by anion-fiber would influence the human physiology and psychology. Dynamic continuous blood pressure and electroencephalogram were examined during a 5-h exposure to negative air ions created by anion-fiber in ten adult healthy volunteers. Physiological experiment research was carried out in environmental science laboratory with the anion-fiber curtain. The concentration of negative ions is above 1300 ion/cm3 and the normal standard is 720 ion/cm3.The results suggest that the dynamic continuous blood pressure and skin temperature could possibly be reduced (P<0.01) and the β index of each region decreased significantly.
