The Interaction of Specific Frequency Bands in the Geomagnetic Field Diurnal Spectrum, With Specific Frequency Bands in the Human Heart Rate Variability Diurnal Spectrum

" For over 50 years, experiments have been demonstrating an interaction between the dynamics of the human heart and the dynamics of the earth’s magnetic field. In these experiments, specific frequency components in the variability of the geomagnetic field (GMF), involving micropulsations, are shown to significantly interact with specific frequency components in human heart rate variability (HRV). A significant difference was found in the HRV ratio of VLF/HF, on days of low geomagnetic variability (L gmf) compared with days of high geomagnetic field variability (H gmf) (P = 0.0001, n = 24, effect size 1.014)." {Credits 1}

" It was shown that there was a correspondence in the power spectra of the high (HF) and very low (VLF) frequency components in HRV and GMF variability. It was shown that there was a significant difference in the ratio of the VLF and HF frequency band power of the HRV between the ECGs recorded during days of lower geomagnetic variability, and days of higher geomagnetic variability." {Credits 1}

" This may support a hypothesis that high GMF variability, or GMF storms, may act as a physiological stressor, by altering autonomic nervous system responses in the vagal system of the heart, (5,13b,13c). In these experiments, the GMF variability was small, even in the H gmf condition, compared with the degree of variability noted in geomagnetic disturbance during peak sunspot activity in some epochs. However, even with the relatively small, albeit significant differential between L gmf sds and H gmf sds in these experiments (1.95 : 1) (n= 35 and 24, respectively,) significant effects are shown in physiologically indicative parameters of the ECG HRV." {Credits 1}

" It seems that there is some coherence between the harmonics of the geomagnetic field variability and the harmonics of the heart variability. The HF band in the GMF has similar frequency and time series range (10s-45s) as the VLF band in the ECG (25s – 333s). The HF band in the GMF has less power at night, when the VLF band of the ECG has higher power. The HF band in the GMF varies slightly in its peak frequency, according to the season and the time of day (7), and conditions in the solar, ionospheric and geospheric activity, which may include the technologically produced electromagnetic environment (13a) as well as the earth’s inner and outer structural components. Perhaps, one might hypothesise, that in a Page 15/28 relatively healthy heart, the heart adapts optimally with a resonant response to the changing parameters in the GMF. However, if that natural adaptation becomes maladjusted for any reason, possible disturbance in autonomic control of the heart vagal system control may manifest as subtle changes in HRV, and ultimately, over the long term, in health." {Credits 1}

" It seems from research, that heart rate harmonics are meaningful, and synchronise in a meaningful way with harmonics of the GMF. Harmonics and subharmonics are meaningful in terms of complex nonlinear signalling systems (4a,22a,24a). Human biology, geophysical phenomena, astrophysical phenomena, all exhibit complex signalling, involving complex waveforms, that can be analysed or deconstructed into component harmonic frequencies. There is information in these signal waveforms, and in their harmonics. This is how the commensality of the universe evolves, in cooperative harmony, maintaining form and content; each part holding and reading information from the whole; a holographic evolution of chaotic systems." {Credits 1}

" There are processes within the earth that involve piezoelectric and pyroelectric activity in the rocks and the molten mantle around the core, and the viscous layers beneath the crust. It has been noted recently that many of the rocks in the earth have piezoelectric and pyroelectric properties, (9). Amongst the most common are quartz and ice, which includes the large ice deposits in the polar regions (25,26,27). Regional rock strata vary, and so do the pressure and temperature changes in the rocks, caused by convection currents in the molten viscous mantle, heating and cooling, and the expansion and contraction that accompanies this, the grinding of the continental plates, and concomitant shear and stress tensions, (10). Radioactivity in rocks contribute to all of these effects. These forces are difficult to measure, but may be witnessed in the seismic graphology, which records electric field changes in the earth. They may also manifest in the micropulsations in the geomagnetic field, monitored by magnetometers." {Credits 1}

" Schumann resonance of the earth is designated as a 7.83 Hz electromagnetic wave, travelling around the circumference of the earth in the 60 mile ionospheric cavity between the crust and the upper atmosphere. It resonates with itself as it completes every 2 or 3 circuits, (28). This ultra low frequency wave varies around 8Hz, and has subharmonics, which vary according to diurnal, seasonal, solar and water aerosols in the atmosphere, and other terrestrial phenomena which may include the geomagnetic field. It is possible that some resonance exists between the geomagnetic field, the Schumann resonance and the human heart, and this would be in the subharmonic region of the Schumann spectrum (28a) It is of interest to note that the Schumann frequency lies within the alpha band of the human electroencepholagraph (EEG) brain wave spectrum. The EEG alpha band lies between 8 – 12 Hz, and is correlated with a relaxed and unfocussed state of mind, or ‘neutral gear’ for the brain activity, according to neurofeedback research, (29a, 29b). This relaxed state might correlate with the vagal tone in heart rate variability (22a)." {Credits 1}

" There are, indeed, real dynamic mechanisms within the earth that can manifest in the variability of micropulsations in the PC3 HF band of the geomagnetic field, which in turn corresponds in its rhythmicity, to the VLF band in the human ECG, which in turn, can synchronise with these subtle changes, in a finely tuned balancing act, known as homeostasis, fundamental to all successful life forms on the earth." {Credits 1}
