The purpose of our study is to study changes in the power characteristics of the bioelectric activity of the human brain under the influence of speleoclimatotherapy. The study involved 14 volunteer students, aged 19-22. The electroencephalogram of patients was recorded in a state of functional rest before and after a 2-hour session of speleoclimatherapy using an «Encephalan - EEGR - 19/26» electroencephalograph (Medicom, Taganrog). Analysis of the average power of brain bioelectric activity of various rhythmic ranges showed that the power of the theta rhythm tended to decrease after caving both with closed and open eyes of the subjects. In a state of functional rest with open and closed eyes, the stress in the central nervous system decreased after exposure to electronegative air ions. The power of the beta-1 rhythm with closed and open eyes, and the alpha rhythm with open eyes increases after caving. At rest, with closed eyes, the alpha rhythm power decreased slightly in the Cz and C4 regions, the rest - increased. Changes in the power of beta-2 rhythm are ambiguous. In the functional state of rest with closed eyes, the hemisphere asymmetry of the arising changes manifested itself, on the right, the power of the theta rhythm decreased, on the left, it mainly increased. The obtained results allow us to recommend speleoclimatotherapy as a method of non-pharmacological correction and prevention of prenosological changes in the health and electrical activity of students' brains, with caution, in a state of health or remission, taking into account the individual approach to each patient and controlling the main parameters of his health during the course of speleoclimatotherapy.
