An alternating current of 100,000 Hz or higher is called a high-frequency current, and when this high-frequency vibration is transmitted to the human body, molecules within the body’s tissue cells rub against each other, and heat is generated inside the body due to collisions such as the movement of positive and negative ions and the rotational movement of molecules.
The heat generated by high frequency is transmitted deep into the body through vibration friction heat and is called ‘deep heat’, and high frequency stimulators helps increase deep heat.
