When activated by an built - in electric waves yanging from 2 to 25 ( microns ) in wavelength and 28 to 34 mw / sq . cm in intensity that coincide with the wavelengths and intensity of the electromagnetic waves released by a human body and are cosquently absorbed by the body ( so - called selective absorption ) 其内部所含元素可以通过电能转换为热能,当激发到一定温度,便会产生一种具有不同波长和不同能量的综合电磁波,这种被吸收的电磁波能增强人体的自身调节机制及免疫力,使症状迅速康复,提高机体抵抗力。
