Solar Storms & Heart Attacks: New Study Links Geomagnetic Disturbances to Increased Risk, Especially in Women
(Last Updated: October 26, 2023)
Almost 15 million kilometers separate the Earth and the Sun. Despite this vast distance,solar eruptions – sudden and violent releases of energy from the Sun’s surface – have a demonstrable impact on our environment. These impacts range from the mesmerizing aurora borealis (Northern Lights) to disruptions in electrical grids and satellite communications. But emerging research suggests these solar storms may also have a direct and harmful effect on human health, specifically increasing the risk of heart attacks.
Researchers from the São Paulo Research Foundation (FAPESP) have discovered a link between disturbances in the Earth’s magnetic field, resulting from solar storms, and an increase in the frequency of heart attacks. The effect appears to be more pronounced in women.
Solar Eruptions and Heart Attacks: Women Seem More at Risk
The study, published in Communications Medicine, analyzed the medical records of 871 men and 469 women in Brazil who were treated for myocardial infarction (heart attack) between 1998 and 2005. This period was chosen due to its classification as a time of intense solar activity. Researchers correlated these records with data from the KP index – a measure of variations in the Earth’s geomagnetic field – classifying days as calm, moderate, or disturbed based on the KP score.
“It should be noted that the number of heart attacks in men is almost twice as high,whatever the geomagnetic conditions. But when we examine the relative frequency of cases, we note that for women, it is significantly higher in geomagnetic conditions disturbed compared to calm conditions,” explains Luiz Felipe Campos de Rezende, researcher at the National Institute for Spatial Research in Brazil (INPE) and the corresponding author of the article. “In the age group of 31 to 60, it is up to three times more likely for a woman to experience a heart attack during a period of geomagnetic disturbance.”

Understanding the Connection: How Do solar Storms Affect the Heart?
The exact mechanisms linking geomagnetic disturbances to heart attacks are still under inquiry. Several theories are being explored:
- Changes in Blood Viscosity: Some research suggests that geomagnetic fluctuations can alter blood viscosity, potentially increasing the risk of clot formation.
- Autonomic Nervous System Disruption: Solar storms may disrupt the autonomic nervous system, which controls heart rate and blood pressure, leading to instability.
- Inflammation: Geomagnetic activity could trigger inflammatory responses in the body, contributing to cardiovascular risk.
- melatonin Suppression: Solar flares can suppress melatonin production,a hormone with antioxidant and cardiovascular protective properties.
