“…Finally, heliobiology investigates the correlation of the geomagnetic disturbance to the health of humans and other biospheric processes, e.g. [13–15], the MF being regarded as an immediate cause of the correlations [16]. All these effects form a variety of the so-called non-thermal magnetic biological effects.…”

“…One of the principal causes for poor reproducibility is the random character and unpredictability of the nonspecific non-thermal effects. It has not yet been possible to find the causes that control the appearance of nonspecific effects or summarize the outcomes of this research under any theory [16]. In these conditions, the mere accumulation of low-reproducible experimental data has failed to elicit an understanding of the biophysical underpinning of these effects and will hardly be useful in disclosing the nature of magnetoreception.…”

During interplanetary flights in the near future, a human organism will be exposed to prolonged periods of a hypomagnetic field that is 10,000 times weaker than that of Earth’s. Attenuation of the geomagnetic field occurs in buildings with steel walls and in buildings with steel reinforcement. It cannot be ruled out also that a zero magnetic field might be interesting in biomedical studies and therapy. Further research in the area of hypomagnetic field effects, as shown in this article, is capable of shedding light on a fundamental problem in biophysics—the problem of primary magnetoreception. This review contains, currently, the most extensive bibliography on the biological effects of hypomagnetic field. This includes both a review of known experimental results and the putative mechanisms of magnetoreception and their explanatory power with respect to the hypomagnetic field effects. We show that the measured correlations of the HMF effect with HMF magnitude and inhomogeneity and type and duration of exposure are statistically absent. This suggests that there is no general biophysical MF target similar for different organisms. This also suggests that magnetoreception is not necessarily associated with evolutionary developed specific magnetoreceptors in migrating animals and magnetotactic bacteria. Independently, there is nonspecific magnetoreception that is common for all organisms, manifests itself in very different biological observables as mostly random reactions, and is a result of MF interaction with magnetic moments at a physical level—moments that are present everywhere in macromolecules and proteins and can sometimes transfer the magnetic signal at the level of downstream biochemical events. The corresponding universal mechanism of magnetoreception that has been given further theoretical analysis allows one to determine the parameters of magnetic moments involved in magnetoreception—their gyromagnetic ratio and thermal relaxation time—and so to better understand the nature of MF targets in organisms.

“…Despite the smallness of the values of geomagnetic disturbances compared with urban MF, when comparing their integral powers over a wide range of 10 −5 –1 Hz, the correlations between magnetic storms and the state of the human organism are reliably established [Breus et al, 2016]. There is evidence of a direct effect of artificial magnetic storms on the human organism [Gurfinkel et al, 2018; Pishchalnikov et al, 2019], as well as on planktonic species [Krylov and Osipova, 2019].…”

“…This implies that a weak low‐frequency signal of an MF, regardless of its origin, will not pass through the primary magnetic sensor if the latter is “disabled” by a powerful high‐frequency component. If the effect of magnetic storms is still observed, then the organism should possess certain integrating mechanisms capable of eliminating the effect of high‐frequency components; as Breus et al [2016] suggest, the integration is realized in the form of long‐term changes in the concentration of biochemical agents with a long decay period.…”

In this study, we measured and analyzed the spectral characteristics of a low‐frequency magnetic field (MF) inside several gasoline‐powered cars while driving on busy city roads. The spectra obtained upon measurements in the interior of the cars are compared with those measured in office locations at different times of the day and with different disturbances of the geomagnetic field (k‐index of disturbance 2–8). The power spectral density of the electromagnetic field in cars moving on busy roads in the frequency range of 10−3–102 Hz is one to three orders of magnitude higher than that in urban offices. This raises a question regarding the possible influence of these MFs on the psychophysiological state of drivers. In turn, in the daytime, the MF power in the range from 10−3 to 1 Hz inside the locations is three times higher compared with the power of a strong geomagnetic storm. Despite such an overwhelming magnetic background, geomagnetic storms affect various organisms. The nonspecific effect of magnetic storms is supposed to be associated with relatively long (lasting several hours or more [frequency range of 10−4−10−5 Hz]) periods of enhancement or weakening of the local geomagnetic field. In this range, especially at night, the power spectral density of geomagnetic disturbances is comparable to and can even exceed the power density of urban MFs. © 2020 Bioelectromagnetics Society.

This review presents contemporary data on the biological effects of geomagnetic activity. Correlations between geomagnetic indices and biological parameters and experimental studies that used simulated geomagnetic storms to detect possible responses of organisms to these events in nature are discussed. Possible mechanisms by which geomagnetic activity influences organisms are also considered. Special attention is paid to the idea that geomagnetic activity is perceived by organisms as a disruption of diurnal geomagnetic variation. This variation, in turn, is viewed by way of a secondary zeitgeber for biological circadian rhythms. Additionally, we discuss the utility of cryptochrome as a biological detector of geomagnetic storms. The possible involvement of melatonin and protein coding by the CG8198 gene in the biological effects of geomagnetic activity are discussed. Perspectives for studying mechanisms by which geomagnetic storms affect organisms are suggested. Bioelectromagnetics. 38:497-510, 2017. © 2017 Wiley Periodicals, Inc.
