Apparatus for carrying out treatments on the human body, which comprises a central unit configured to produce a hot fluid and a cold fluid, and a compressor. The apparatus also has at least two operational heads, each provided with a plate intended to contact the skin of the patient, and susceptible of being temperature-conditioned with a corresponding hot or cold fluid. The plate is associated with a plurality of pneumatic actuators, each comprising a piston, which is slidably inserted in a hole obtained in the plate, and a return spring which acts on the piston. The piston is pneumatically operable to move between a retracted position and a protruding position, through a plurality of solenoid valves, each of which is associated with a corresponding pneumatic actuator housed in the operational head, connected to the compressor and provided with an opening for air discharge.
