It is shown that the mechanism of action of magnetic fields at body level is based on the development of unspecific adaptational reactions of the body - stress and anti-stressor reactions; elevated activation, calm activation and training. The character of the changes in the body and its subsystems (reaction pattern) is determined by the type of unspecific adaptational reactions of the body developing under the influence of a magnetic field. In the presence of stress the parameters of homeostasis go beyond the norm and protection is interwoven with damage; in anti-stressor unspecific adaptational reactions of the body on training, changes are observed within the lower half of the zone of the norm, on calm activation the upper half and with elevated activation are somewhat higher than normal. The dependence of the type of reaction on the value of magnetic induction and frequency is periodic: as these parameters change, there is regular repetition of the unspecific adaptational reactions at different levels of reactivity of the body. The unspecific adaptational reactions of the body at high reactivity levels (to weak ultralow-frequency magnetic fields) are more favourable, low reactivity levels (strong magnetic fields) have the features of tension and desynchronization. The anti-stressor unspecific adaptational reactions of the body, especially activation of high reactivity levels, raise unspecific resistance in contrast to stress, with no elements of damage and no waste of energy and exert an anti-tumour, protective (in relation to toxic preparations and in irradiation) and are rejuvenating effect, promoting self-organization. The patterns of the unspecific adaptational reactions of the body match the behaviour of complex non-equilibrium systems.
