Effects of far infrared rays on hydrogen peroxide-scavenging capacity

Far infrared rays (FIRs) have several proven effects on the human body and are generally considered to be biologically beneficial. In this study, we determined the effect of FIRs on hydrogen peroxide (H2O 2)-scavenging activity, which was directly increased by 10.26% after FIR application. Even in the indirect use of FIRs accompanying carrot extract, FIRs still contributed to a 5.48% increase in H2O2- scavenging activity. We further proved that additional FIR treatment resulted in about 23.02% and 18.77% viability increases of osteoblast cells in the 200 and 800 μM H2O2, respectively; and about 25.67% and 47.16% viability increases of fibroblast cells in the 25 and 50 μM H 2O2, respectively. Finally, FIR treatment also delayed senescence of detached Railway Beggarticks leaves in H2O2 solution with the concentrations of 10, 100, and 1000 μM. By reviewing past articles related to the effects of oxidative stress from metabolically produced H2O2, we discuss possible benefits of FIRs for plants and animals.
