The device comprises a voltage converter that receives altern voltage through a connection to the grid (4) with ground connection (5) and transform it at the exit of the converter into direct voltage, a first conductor (2) electrically connected to the positive pole (6) at the exit of the converter and a second conductor (3) electrically connected to the ground connection (5) of the grid (4), so that, a user who connects to the first conductor (2) and to the second conductor (3), when turning the voltage converter on, receives an electric current across his body, that produces the discharge of residual electromagnetic energy stored in the body.
