Introduction: Determination of individual reactions of the nervous system during self-regulation under experimental cold conditions has a potential to contribute to better understanding of the "physiological costs" humans "pay" for adaptation to the climatic factors of the Arctic. Aim: To study the dynamics of the spectral power of the electroencephalogram (EEG) during heart rate variability biofeedback (HRV BF) sessions in experimental hypothermia. Methods: Thirty healthy male volunteers (18-20 years old) participated in the experiment. The experimental group consisted of men who performed the HRV BF session (n = 15) and the control group (n = 15). The experiment included five stages: I - rest (+20 °С); II - HRV BF session for the experimental group and rest for the control group; III - whole cooling (-20 °С) for 10 min; IV and V - states after cooling, similar to stages I and II, respectively. EEG were recorded during each stage of the study using a portable electroencephalograph "Neuron-Spectrum-SM" (Neurosoft, Russia). Results: Body temperature significantly decreased on average by 2.2-2.7 °С (p
