Apparatus for massaging the human body, which comprises: - a central unit; - pneumatic driving means comprising at least one compressor housed in said central unit; - at least two operational heads, each connected to the central unit for receiving control and fluid signals and provided with: ∘ a plate having at least one treatment surface intended to contact the skin of the patient to be treated; ∘ a plurality of pneumatic actuators connected to said compressor and each comprising: • a piston, which is slidably inserted into a hole obtained in said plate and facing said treatment surface, provided with a free end intended to contact the skin of the patient; • a return spring acting on said piston, the latter being operable by said pneumatic driving means to move between a retracted position, in which said free end is contained within said hole, and a protruding position in which said free end extends protruding from said treatment surface, said piston having overcome the action of said return spring; characterized in that: - said pneumatic driving means further comprise a plurality of three-way solenoid valves, each of which associated with a corresponding pneumatic actuator by means of a connecting conduit and housed in said operational head, and connected to said compressor and to said pneumatic actuator to check the air supply of said pneumatic actuator, and provided with an opening for air discharge, through which said solenoid valve is susceptible of discharging the pressurized air contained in said pneumatic actuator and in said connecting conduit to bring back the piston to said retracted position; - said apparatus further comprises heating means for the production of a hot fluid housed in said central unit, cooling means for the production of a cold fluid housed in said central unit; each said operational head being provided with at least one exchanger for the thermal exchange with one corresponding fluid of said hot and cold fluids so that said plate is heated or cooled by means of said heating means or said cooling means. - a central unit;
