Heat is generated when high frequency currents goes into the human body (this heat is called Endogenous Dermal Heat) because every time the direction of current changes, the molecules that compose tissues vibrate and produce friction spinning, twisting, colliding.
Unlike other type of currents, this high frequency current does not stimulate a sensory nerve or a motor nervehydrostatic. Therefore, it can heat up a particular part of the human body’s tissues without any discomfort or muscle shrinkage. Body heat converted from high frequency energy heats up tissues, and it promotes the function of cells, increases blood flow, and so on.
42°C is generally known for the proper temperature for tissue function recovery. When the temperature of a part of a tissue exceeds 40° C, it makes arteries and capillaries expand, and increases blood flow. Therefore, it improves the human body’s defense mechanism, the circulation of blood, and metabolism.
Compared to when we rest, the blood flow amount increased by E.D.H. goes 5 to 6 times higher. Moreover, oxygen, nutrition, antibody, and white blood cell supplies increase. The expansion of blood vessels increases the pressure of capillaries, and it promotes the lymph’s circulation system.
