“…Research shows that daily activity of the autonomic nervous system not only responds to changes in solar and geomagnetic activity, but is also synchronized with time-varying magnetic fields associated with geomagnetic field line resonances and Schumann resonances that coincide with physiological rhythms [9], [10], [11] and may affect human health [12], [13], [14].…”

The human body, even at rest, needs energy to perform necessary physiological functions. Strict conditions are required for measuring basal metabolic rate (BMR). Many factors that have a direct impact on BMR including the condition of autonomic nervous. All living systems are affected by external and internal environments. One factor in the external environment is the Earth's magnetic field, which fluctuates over a wide frequency range. A series of studies indicate that low frequency magnetic fields can affect cellular mitochondrial activity and impacts every cell's metabolism. Information on gas metabolism during respiration was obtained by indirect calorimetry using a system where the gas flow was continuously analyzed. Time varying local Earth magnetic field data were recorded at a magnetometer site located in Lithuania using 2 induction coil magnetometers. For all magnetic field data, power spectral density PSD was calculated for every hour (fast Fourier transformation) in the band between 0.32 to 36 Hz. Investigations of metabolic rate were performed in Lithuanian during 2016-2020 years. We assessed 395 persons: 116 men and 279 women. Conclusions: 1) Oxygen consumption has significant negative correlation with local geomagnetic field activity; 2) Metabolic rate decreases with increases in local geomagnetic time varying field power; 3) Measured metabolic rate decreases with increase of local geomagnetic field power.

Statistical Associations between Geomagnetic Activity, Solar Wind, Cosmic Ray Intensity, and Heart Rate Variability in Patients after Open-Heart Surgery

The aim of this study was to identify associations of the parameters of heart rate variability (HRV) with the variations in geomagnetic activity (GMA), solar wind, and cosmic ray intensity (CRI) in patients after coronary artery bypass grafting or valve surgery in Kaunas, Lithuania, during 2008–2012. The data from 5-minute electrocardiograms (ECGs) in 220 patients were used. ECGs were carried out at 1.5 months, 1 year, and 2 years after the surgery (N = 495). A lower (higher) very-low-frequency-band (VLF) and a higher (lower) high-frequency band (HF) in normalised units (n.u.) were associated with a low maximal daily 3-hourly ap (the DST index > 1). A lower mean standard deviation of beat-to-beat intervals (SDNN) and VLF, LF, and HF powers were lower in patients when Ap < 8 occurred two days after the surgery, and a low solar wind speed (SWS) occurred two days before the ECG. The effect of CRI was non-significant if the linear trend was included in the model. Low GMA and a low SWS may effect some HRV variables in patients after open-heart surgery. The GMA during the surgery may affect the SDNN in short-term ECG during the longer period.
