Abstract

Overview

The study explores the ambiguous relationship between geomagnetic fields (GMF), geomagnetic disturbances (GMD), and the occurrence of cardiovascular diseases (CVDs) on a global scale.

Background

• Focus on the correlation between stable and unstable geomagnetic activities with the health outcomes related to CVDs.

Method

This research was grounded on data from the Global Burden of Disease study of 2019, covering 204 countries and territories. It analyzed GMF intensity, GMD frequency, CVDs events alongside weather and economic health indicators spanning from 1996 to 2019.

Methodologies used include linear regression and multi-factor panel data analysis to adjust for confounding factors and identify correlations between GMF, GMD, and CVD events.

Findings

• Positive correlation discovered between total GMF intensity and CVDs mortality.
• Negative correlation observed with the horizontal component of GMF intensity.
• Analysis adjusted for confounding factors confirmed these trends.
• In high-income areas, a positive correlation between geomagnetic storms and CVD mortality was noted, diminishing toward the equator.

Conclusion

The research highlights the beneficial effects of stable, horizontal GMF and the potential health risks associated with unstable, short-term geomagnetic disturbances on cardiac health.
