“…In addition, magnetic storms affect the dynamics of the speed of capillary blood flow. Periodic changes in the speed of skin microcirculation are a very sensitive marker of the physiological state of the body under normal conditions, with age-related changes and pathology [87][88][89][90][91][92]. The effects on microcirculation consist of an increase in the amplitude of oscillation of skin blood flow rate in response to magnetosphere disturbances [62].…”

“…It is very informative to assess the degree of correlation between microcirculation fluctuations in different rhythms. This approach can be used for noninvasive techniques for diagnosing and monitoring the development of diabetes mellitus, bronchial asthma, and other pathologies [90,91,[93][94][95][96][97]. The use of a correlation approach to the study of microcirculation oscillations in different rhythms during a magnetic storm may open new aspects of the physiological effects of weak ELF-MFs in the future.…”

Magnetic fields are a constant and essential part of our environment. The main components of ambient magnetic fields are the constant part of the geomagnetic field, its fluctuations caused by magnetic storms, and man-made magnetic fields. These fields refer to extremely-low-frequency (<1 kHz) magnetic fields (ELF-MFs). Since the 1980s, a huge amount of data has been accumulated on the biological effects of magnetic fields, in particular ELF-MFs. However, a unified picture of the patterns of action of magnetic fields has not been formed. Even though a unified mechanism has not yet been generally accepted, several theories have been proposed. In this review, we attempted to take a new approach to analyzing the quantitative data on the effects of ELF-MFs to identify new potential areas for research. This review provides general descriptions of the main effects of magnetic storms and anthropogenic fields on living organisms (molecular–cellular level and whole organism) and a brief description of the main mechanisms of magnetic field effects on living organisms. This review may be of interest to specialists in the fields of biology, physics, medicine, and other interdisciplinary areas.

“…After an occlusion test in healthy volunteers, increases in the amplitudes of oscillations in the skin microcirculation of all five rhythms were observed [190]. Decreases in the amplitudes of skin microcirculation oscillations in the intervals of myogenic, neurogenic, and NO-dependent endothelial rhythms were shown in bronchial asthma (BA) patients with a low expiratory volume in the first second (FEV1) compared with apparently healthy volunteers and patients with BA with high FEV1 values [189,190]. The decrease in FEV1 in BA also affected PORH by reducing the change in the amplitude of oscillations in the microcirculation rate in the myogenic and NO-dependent endothelial rhythm [206].…”

“…), and understanding the characteristics of intracellular signaling in these cells may be the key to developing new therapeutic approaches to the treatment of socially significant diseases [279]. Secondly, one of the functions of endotheliocytes is the regulation of the rate of skin microcirculation [179,187,[189][190][191][192]. The following question arises: are the rhythms of oscillations in the skin microcirculation and the rhythms of oscillations in calcium and other signaling molecules in endotheliocytes related?…”

The presence of biological rhythms is a characteristic of all living organisms. Over the past 60 years, scientists around the world have accumulated a huge amount of data on rhythmic processes in living systems at various levels. The acquired knowledge has found applications in human economic activity and medicine. The ultradian (less than a day) rhythms at the organismal, organ, and cellular levels are characterized by high diversity. Unfortunately, biorhythms in different systems are considered, most often, in isolation from each other. Much knowledge about biorhythms was obtained using expert evaluation methods, and later methods of spectral analysis were used to describe biorhythms. Ultradian rhythms have a relatively short duration; therefore, they can be characterized by spectral analysis methods. More and more researchers believe that in order to further expand the understanding of the nature and purpose of biorhythms, the use of more advanced methods of mathematical processing is required, and rhythms in different organs, tissues, and cells should be considered parts of a single system. This review is intended to provide the reader with the variety of ultradian rhythms in living systems (organismal, organ, cellular, molecular levels), the mechanisms of their generation, and their functions to give the reader a picture of the possible relationships between these rhythms. Further, the reader will be able to get acquainted with the variety of mathematical methods for analyzing biorhythms, including bispectral and cross-correlation analyses.
