Germanium is a metal semiconductor, the outermost track has 4 electrons to make irregular movements. When the temperature is above 32 degrees, one of the electrons will excite off the orbit and create negative ions.
Function of Germanium fiber
Enhance human immunity, Anion can accelerate energy exchange, reduce
Far infrared, improve blood circulation and make the body warm.
Release negative ions, Anion can accelerate energy exchange, reduce fatigue and rapidly recovery.
