Therapeutic heating pads usually operate from household current and must have protection against overheating.
A moist Heating Pad is used dry on the user's skin. These pads register temperatures from 76 to 82 °C (169 to 180 °F) and are intended for deep tissue treatment and can be dangerous if left on unattended. Moist Heating Pads are used mainly by physical therapists but can be found for home use. A moist cloth can be added with a stupe cover to add more moisture to the treatment.
