| Studies of the long-term trend of the geomagnetic aa-indices has revealed that occurrence probability of quiet magnetic conditions (aa < 7 nT) has been gradually reduced during the 20th century from 50% to 10%. Similar trend of local magnetic k indices at Moscow during 2002 at the declining phase of the 23d solar cycle has been compared with electroacupunctural (EAP) measurements of human electrical conductivity carried out at Institute of Terrestrial Magnetism, Ionosphere and Radio Wave Propagation (IZMIRAN) since 1998 (http://helios.izmiran.rssi.ru/helioecology/index.html). Method of electroacupunctural diagnostics of health condition by R.Voll is used (M.V.Ragoulskaya, V.V.Lyubimov, Investigation of natural magnetic fields′ influence on human biological active points: methods, equipment, results. El. J.of Biomedical Electronics, Nov. 2000). Accumulation of k-index for 27 days (corresponding to rotation of the Sun) preceding day of EAP measurements is used for estimate the percentage occurrence probability of k-index (k<2 for quiet magnetic conditions and k>2 for disturbed magnetic conditions). It is shown that average daily human conductivity EAP index has been gradually reduced during 2002 correlated with the same trend of occurrence of quiet local k-index at Moscow and several other local and planetary estimated k indices. Our EAP results confirm that human conductivity is sensitive to reduced quiet (grown disturbed) magnetic activity. Technological developments may be required for human adapting to reduced quietness of magnetic field. |
