Abstract: during the school year, 51 pupils of 10-11 grades studied the changes in the intensity of situational anxiety and the Cerdo autonomic index to assess the impact of psychological stress on blood pressure and the development of an imbalance of the autonomic nervous system depending on the need to pass final exams learning process. Depending on the need to pass the final exams at the end of the school year, students were divided into 2 groups. The first control group consisted of 26 students of the 10th grade, who at the end of the school year did not pass the UNT. The second group consisted of 25 pupils of the 11th grade, who at the end of the school year were to pass the UNT. It was established that as the final exams in Group II approached, compared with I, the intensity of situational anxiety significantly increased (P˂0.05), which led to an increase in the frequency of increase in blood pressure (P˂0.05) and imbalance of the functional state of the vegetative nervous system (P˂ 0.05). The results indicate that in order to prevent arterial hypertension and autonomic dysfunction, it is necessary to carry out activities aimed at increasing resistance to psychological stress.
