Features of Lipid Metabolism and Psychophysiological Reactions in Healthy Male Subjects during 24-Hour Exposure to a Hypomagnetic Environment

Lipid metabolism was studied in six subjects during a 24-h stay in a hypomagnetic medium with a weakening of 350, 650, and 1000 times relative to the geomagnetic field. Psychological testing was conducted in parallel. It was established that in a normal geomagnetic environment (placebo series) and a hypomagnetic one, the content of lipid substrates of energy metabolism increases in the blood due to immobilization stress, which developed as a result of the subjects being in a sitting position during the experiment for three 8-h sessions with minimal movements. When the geomagnetic field weakens by 350 and 650 times, the concentration of phospholipids increases due to changes in their intermolecular interactions in cell membranes. A thousand-fold weakening of the geomagnetic field leads to an increase in the blood of lipid substrates of energy metabolism and apolipoprotein B relative to the background and placebo series, being the body’s reaction to being in a hypomagnetic environment, reflecting its stressfulness. The hypomagnetic environment negatively affects the physical condition of the body, reducing the level of its physiological and psychological well-being. The changes took place within the reference ranges, so the reaction to the experimental effect was adaptive.
