Synchronization of human heart-rate indicators and geomagnetic field variations in the frequency range of 0.5–3.0 mHz

et al. 2017

IJERPH

A new analysis technique for the evaluation of the degree of synchronization between the physiological state of a group of people and changes in the Earth’s magnetic field based on their cardiac inter-beat intervals was developed and validated. The new analysis method was then used to identify clusters of similar synchronization patterns in a group of 20 individuals over a two-week period. The algorithm for the identification of slow wave dynamics for every person was constructed in order to determine meaningful interrelationships between the participants and the local magnetic field data. The results support the hypothesis that the slow wave rhythms in heart rate variability can synchronize with changes in local magnetic field data, and that the degree of synchronization is affected by the quality of interpersonal relationships.

“…Khabarova and Dimitrova demonstrated that the magnetic waves in the 2–10 mHz region had the higher correlations with increased blood pressure than geomagnetic indices 69 . In addition, Zenchenko et.al found there was a significant degree of synchronization between HRV rhythms and the osculation’s in geomagnetic field in the frequency range between 0.5 to 3.0 mHz in two-thirds of their experiments of over periods of 4 to 30 minutes 78 . It has also been demonstrated that ANS activity not only reacts to shifts in geomagnetic and solar activity, it can also synchronize with rhythms in the time-varying magnetic fields related to the Schumann resonances (SR) and geomagnetic field-line resonances 15 , 79 .…”

Long-Term Study of Heart Rate Variability Responses to Changes in the Solar and Geomagnetic Environment

This long-term study examined relationships between solar and magnetic factors and the time course and lags of autonomic nervous system (ANS) responses to changes in solar and geomagnetic activity. Heart rate variability (HRV) was recorded for 72 consecutive hours each week over a five-month period in 16 participants in order to examine ANS responses during normal background environmental periods. HRV measures were correlated with solar and geomagnetic variables using multivariate linear regression analysis with Bonferroni corrections for multiple comparisons after removing circadian influences from both datasets. Overall, the study confirms that daily ANS activity responds to changes in geomagnetic and solar activity during periods of normal undisturbed activity and it is initiated at different times after the changes in the various environmental factors and persist over varying time periods. Increase in solar wind intensity was correlated with increases in heart rate, which we interpret as a biological stress response. Increase in cosmic rays, solar radio flux, and Schumann resonance power was all associated with increased HRV and parasympathetic activity. The findings support the hypothesis that energetic environmental phenomena affect psychophysical processes that can affect people in different ways depending on their sensitivity, health status and capacity for self-regulation.

“…Khabarova and Dimitrova also found that the ULF waves between 2–10 mHz had the strongest correlation with increases in blood pressure (0.6) compared to geomagnetic measures (0.3) [ 6 ]. In addition, Zenchenko et al reported that in two-thirds of their experiments, they found a synchronization between heart rhythms and the ultra-low frequency components (0.5 to 3.0 mHz) of the geomagnetic field [ 58 ].…”

Synchronization of Human Autonomic Nervous System Rhythms with Geomagnetic Activity in Human Subjects

Štolc

et al. 2017

IJERPH

A coupling between geomagnetic activity and the human nervous system’s function was identified by virtue of continuous monitoring of heart rate variability (HRV) and the time-varying geomagnetic field over a 31-day period in a group of 10 individuals who went about their normal day-to-day lives. A time series correlation analysis identified a response of the group’s autonomic nervous systems to various dynamic changes in the solar, cosmic ray, and ambient magnetic field. Correlation coefficients and p values were calculated between the HRV variables and environmental measures during three distinct time periods of environmental activity. There were significant correlations between the group’s HRV and solar wind speed, Kp, Ap, solar radio flux, cosmic ray counts, Schumann resonance power, and the total variations in the magnetic field. In addition, the time series data were time synchronized and normalized, after which all circadian rhythms were removed. It was found that the participants’ HRV rhythms synchronized across the 31-day period at a period of approximately 2.5 days, even though all participants were in separate locations. Overall, this suggests that daily autonomic nervous system activity not only responds to changes in solar and geomagnetic activity, but is synchronized with the time-varying magnetic fields associated with geomagnetic field-line resonances and Schumann resonances.
