Effect of weather conditions as ecological factors on vegetative somatic parameters of the preschool children organism

Influence of meteorological environmental factors on people sensitive to severe weather changes manifests itself in the deterioration of health and violation of vegetative functions. One of the main systems of the body, which is sensitive to changes of atmospheric pressure is the cardiovascular system. In people with impaired preventive regulation of vascular tone, who are called weather sensitive, sudden changes in atmospheric pressure can cause jumps of arterial pressure, which can be represented both by its increase (hypertensive crisis) and decrease below the physiological norm, which leads to the decrease of muscle tone and subjective feelings of fatigue. Psychophysiological status of children of preschool age depends significantly on weather conditions due to imperfect preventive regulation of the blood circulation. Due to this, preschoolers feel unwell, their adaptation possibilities go down. This is manifested in changes in blood pressure and a certain decrease in the lability of the motor analyzer defined by means of the tapping-test. Cyclonic changes in climatic conditions have a more pronounced impact on the state of the organism, causing an increase in fatigue and decrease of adaptation reserves, indicating the decrease of one of the most important integral indicators of the vegetative coefficient. Hyperbaric effects associated with the passage of the anticyclone cause less visible changes of the cardiovascular system, compared to cyclonic events. Cyclonic phenomena accompanying low atmospheric pressure, cause depression of the vegetative status of children, a small decrease in tonic activity and as a result negative changes in the basic hemodynamic parameters.
