Impact of Schumann resonance frequencies on acute myocardial infarction in the Southern and Northeastern regions of Brazil

Abstract

This study examines the relationship between Schumann Resonance (SR) frequencies and acute myocardial infarction (AMI) mortality rates in the Southern (S) and Northeastern (NE) regions of Brazil, utilizing geomagnetic data collected between 1996 and 2022 from the São Luís (SLZ) and São Martinho da Serra (SMS) stations. The Discrete Fourier Transform (DFT) was applied to identify SR frequencies, while a cluster analysis grouped states into three distinct patterns. The Southern region exhibited a stronger correlation with SR frequencies, likely due to its proximity to the South Atlantic Magnetic Anomaly (SAMA), where the Earth's magnetic field is weaker, intensifying geomagnetic impacts on cardiovascular health. In contrast, the Northeastern region showed less consistent associations, possibly influenced by local factors. These findings highlight the importance of considering geomagnetic variations in health risk analyses, with significant implications for public health in exposed regions.
