This article examines the psychological and pedagogical features of winter swimming (morzhovanie) in the extreme climatic conditions of the Pavlodar Irtysh region. Pavlodar Irtysh is characterized by a harsh, sharply continental climate, which many consider a risk factor. The problem of strengthening the health of the population in regions with severe climatic conditions remains highly relevant in the modern scientific and applied agenda. Northern regions of Kazakhstan are characterized by long winter periods, significant negative air temperatures, and pronounced wind activity. Prolonged exposure to cold is traditionally considered an unfavorable environmental factor, increasing the risk of respiratory and cardiovascular diseases. At the same time, in recent years there has been a stable increase in interest in natural methods of hardening the body. One of the most radical and controversial methods is winter swimming (morzhovanie) – a short-term immersion in water with a temperature close to zero during the winter period. Objective: To scientifically justify the features of morzhovanie in the conditions of the Pavlodar Irtysh region and determine its effect on the human body, taking into account regional specifics. To achieve this goal, the following tasks were set: to characterize the climatic features of the region, analyze the physiological responses of the body to cold stress, identify potential benefits and risks of winter swimming, and determine the social significance of this movement. Methods: Theoretical methods, clinical-physiological methods, psychophysiological methods, pedagogical and sociological methods, experimental methods (questionnaire, observation, and expert interviews).
