Specific extreme climatic conditions of the North can cause long-term psychoemotional stress, causing violations of the state of adaptive mechanisms of the body and the formation of psychosomatic diseases. Adolescence, due to specific changes in the body, is most susceptible to various stressful factors. The purpose of this work was to study the psychoemotional state and features of the regulatory mechanisms of the body of adolescents living in the North, depending on gender. A study of the level of neuroticism (H) according to G. Eysenck, situational (ST) and personal anxiety (LT) according to Spielberger, analysis of heart rate variability (HRV) using the hardware and software complex "VNS-Spectrum" (LLC "Neuro-Soft", Russia, Ivanovo) in adolescents (n = 58; 30 girls, 28 boys), permanently residing in the city of Yakutsk. Statistical data processing was performed using the program Statistica 13 for Windows. The differences were considered statistically significant at p<0.05. The results show that more than 40% of adolescents (40% - girls, 43% - boys) permanently residing in Yakutsk have a high level of neuroticism, which is significantly higher than in adolescents in Central Russia. Gender differences were revealed in the study of CT and LT. In girls, a high level of CT is detected in 31% of individuals, and a high level of LT is detected in 44%. The values of CT and LT in girls correspond to the average values (40.31±1.85 and 44.06±1.37 points, respectively). Boys have a higher number of individuals with high levels of CT (43%) and LT (54%) than girls. The average CT values are 41.42±1.95 points. Average LT values in boys (45.42±1.56 points), which corresponds to a high level of anxiety. The high level of LT in boys strongly correlates (r = 0.81) with the tension of the mechanisms of regulation of heart activity with the involvement of the suprasegmental Central loop of regulation, which indicates a high level of psychoemotional tension in more than 50% of adolescent boys living in Yakutia.
