[Weather sensitivity of healthy organism]

Healthy organism is featured by keen physiological weather sensitivity. Normally it appears as the brain and behavior responses to the ordinary geophysical factors such as wind conditions, temperature, atmospheric pressure and relative humidity. Based on the comparative evolutionary assessment, behavioral sensitivity to weather grows with its phylogenetic complication within a species, which was demonstrated in rats (Rattus norvegicus), and people. Behavioral response of rats is more acute than of people. In people, correlation between the electroencephalogram rhythms (EEG) and weather fluctuations becomes stronger as frequency of the delta-theta-alpha-beta rhythms increases. This dependence progresses throughout human ontogenesis, i.e. as one matures and advances in age. Number of correlations between the weather and REG or EEG parameters increases nonlinearly within the ontogenetic string from 3 to 72 years of age. Physiological weather sensitivity is manifested by a diversity of reactions enlarging the arsenal of adaptive plasticity of organism.
