Electric potential therapy device

An electric potential therapy device comprising:

• a negative voltage applying unit configured to apply a negative voltage to a living body;
• an electrostatic charge removing unit configured to remove electrostatic charges from inside the living body;
• and
• a controller configured to control the negative voltage applying unit and the electrostatic charge removing unit in a predetermined therapy time in which a therapy cycle is repeated a plurality of times, the therapy cycle consisting of a first period and a second period, wherein:
• the negative voltage applying unit includes a negative voltage generator that generates a negative voltage and a first electrode connected to the negative voltage generator;
• the negative voltage generated by the negative voltage generator is applied to the living body through the first electrode;
• the controller charges the living body to a negative potential in the first period by controlling the negative voltage applying unit to apply the negative voltage to the living body;
• the controller puts the living body into a non-charged state by controlling the electrostatic charge removing unit to remove electrostatic charges from inside the living body in the second period;
• a time duration of the first period is 5 seconds to 30 seconds;
• and
• a time duration of the second period is 1/1000 second to 1/200 second.
