The effect of nonstationary solar processes on human organism was studied. Daily measurements of electrical conductivity of 22 biologically active points on human skin, arterial pressure, and pulse frequency of 30 persons were performed, and their subjective sensations were registered. A comparative analysis of the data and variations in environment parameters, such as local A-index, atmospheric pressure, temperature, and indices of cosmic rays indicated a coincidence of their main periods. The conclusion is made that the reaction of the human organism on abrupt solar disturbances is biphasic and that there is a semiannual wave of synchronization of work of internal organs. The results are confirmed by simultaneous measurements in different cities.
