The invention relates to an apparatus for stimulating local and higher homeostatic autoregulatory mechanisms during the sleep phase and the rest of relaxation phase of the organism by means of a pulsed electromagnetic field. Said apparatus comprises a pulse generator, a control device, and a filed generating device. The pulse generator is designed in such a way as to generate a pulsed electromagnetic field along with the control device and the filed generating device by applying 5 special series of pulses in which the frequency is the same for all signals, ranging from 8 to 15 Hz, the series of pulses are repeated multiple times, and the control time amounts to at least 3.5 h within a period of 7 to 9 hours.
