Effect of hypomagnetic field on the heart

What is it about?

The planning of manned missions in deep space in the absence of the Earth magnetosphere obliges us to take seriously the issue of hypomagnetic conditions (HMC) experimental modeling affecting the human body. Cardiovascular system and the mechanisms of its regulation can be one of the main targets. The issues of creating an artificial geomagnetic field, the safety and reliability of local means of human protection have not been studied enough. Experiments on cellular structures, planaria, snails, laboratory animals in most cases emphasize the negative effect of HMC. Experiments involving humans sometimes give ambiguous results and are carried out under conditions of limited exposure time. Studies involving volunteers have shown that HMC (within 60-90 minutes) or conditions of an alternating magnetic field caused a change in the light flash’s critical frequency, worsened the performance of cognitive tasks, decreased memory, and reaction time . We have conducted studies with an increased time of HMC exposure combined with physical activity limitation. For continuous 8-hour exposition of 8 male volunteers aged (27-38 years), we used the “Arfa” equipment, in which HMC s were created with an average 1000-fold attenuation in the group relative to the Earth magnetic field.
