Еcological and comparative analysis of the influence of weather and climate conditions on the vegetative balance of boys of different age groups

Abstract

Nowadays, when man-made and social conditionsare actively exacerbating the negative effects of environmental factors, the peculiarities of climatic influences are becoming one of the determining factors of human well-being. In the era of urbanization and industrialization, people spend most of their lives indoors in comfortable or subcomfortable microclimate conditions, which reduces its adaptive responses to changing weather parameters. As a result, the dynamic balance between the human body and the externalenvironment and the state of functional activity oforgans and systems of the body is disturbed. It hasbeen established that the body’s response to variousstressors is largely determined by the ratio of the tone of the sympathetic and parasympathetic divisions of the autonomic nervous system. It is the autonomic nervous system (ANS) and, above all, its sympathetic department that has a special role in the formation of body’s adaptive reactions, the development of meteorological reactions, i.e the autonomic nervous system is the primary site of meteorological influences that cause changes in its balance.The determination of vegetative status and direction of vegetative activity in the body of boys was performed using functionalvegetative diagnostics by the method of V. Makats. We examined 1206 boys, 215 boys aged 7–11 years, 861 — aged 12–15 years and 130 boys aged 16–21 years; FVD was conducted in the morning at 10:00-11:00. Since the state of the autonomic nervous system is decisive in the development of meteorologicalreactions analysis of the study data of vegetative tone in sunny, changeable, cloudy and rainy weather and determination of favorable and unfavorable weather conditions for the body.t was found that there are agerelated features of meteorological instability under the influence of meteorological factors on the body of almost healthy young boys. The group of boys aged 16–21 was the most sensitive to changes in weather and climatic conditions, in which the maximum deviations of the activity of functional systems from the age norm were observed and the least sensitive was the group of boys aged 12–15. When analyzing the impact of changes in weather conditions on the body of boys by the vegetative coefficient (kV) it was found that at a rate of kV 0.87–1.13 it increased as much as possible on the effects of rainy weather and was1.23, which indicates a pronounced sympathicotonia,under the influence of variable and cloudy weather on the body, sympathicotonia acquires less pronounced values, 1.08 and 1.13, respectively. Sunny weather can be considered the most ecological and physiological factor influencing the body. In a healthy body, changes in physiological processes and functional activity of systems under the influence of such factors as weather changes are easily compensated and a special role in this belongs to the autonomic nervous system, whose activity provides an adequate response to environmental factors. The knowledge of meteorological sensitivity and meteopathic reactions is necessary for the development of both preventive and curative measures aimed at increasing non-specific resistanceand adaptive mechanisms of the body, the normalization of organ and system function as a basis for normal reactions to adverse environmental changes.
