According to the data of some geophysicists [1-4], from the end of the XXth century the full vector of the magnetic
field of the Earth, following jerks, periodic secular excursions, is gradually weakening. Accordingly the buffering
properties of the Earth magnetosphere, which protects biosystems from excess solar proton-electron beams, are decreasing.
Using modeled weakening of the geomagnetic field we had to answer the question: what are the possible biotropic
consequences of heliophysical pressing for further human development?
The aim of the research was the prognostic evaluation of the possible genetically conditioned polyfunctional human reactions
of healthy male volunteers (n-39) aged 18-20 years to repeated weakening of the magnetic field of the Earth and, if
necessary, the development of preventive non-medicinal technologies.
Results. Significant differences (P <0.05) between volunteers in the experimental and control groups on the dynamics of
electric, psychophysiological and other parameters, coupled with the appropriate genetic markers (genes D4, B1, TNF),
and intensity of heliophysical factors at different stages of ontogeny of the examinees and their parents were showed .
The phenomenon of "heliophysical expression of genes", manifested at modeling of the short-term prolonged geomagnetic
deprivation, was opened. It is shown, that drinking water "AquaHelios" has helioprotective properties and contributes
to significant positive inversion of the functional dependence of many human functional systems on heliogeophysical
impacts, increasing at geomagnetic deprivation. The necessity for the creation of a global system of geoecological human
life support in conditions of spreading heliogeophysical changes of our biosphere and long space missions are scientifically
