Appearance of magnetic storms
Scientists have long debated whether space weather affects human health, with some arguing that there is little to no link. Fresh research in solar biology, however, points in a different direction, offering clearer evidence of a connection between solar activity and physiological responses on Earth.
Space weather describes disturbances in the Earth’s geomagnetic field and atmospheric conditions. Our planet sits inside a protective magnetic shell called the magnetosphere, which shields us from cosmic influences, especially solar flares. Yet at high latitudes there are openings through which streams of charged particles from the Sun can penetrate the atmosphere and interact with terrestrial systems. Tamara Breus, a Doctor of Mathematical Sciences, explains how these solar winds can disrupt geomagnetic balance and trigger magnetic storms, along with auroras that light up polar skies.
When solar wind invades the magnetosphere, the geomagnetic field becomes unsettled, giving rise to magnetic storms and related atmospheric phenomena.

The heliobiologist notes that while people are adapted to such events, health effects can still be significant. Numerous studies point to this influence, suggesting a sensitivity in human biology to geomagnetic fluctuations.
Each cell in the human body carries its own electrical charge, making it responsive to changes in magnetic fields. As Breus puts it, people overall are linked to the weather, even if the impact varies by individual.
Researchers including VIOYu, the principal investigator at the Earth Physics Institute, and Natalia Kleimenova of the Russian Academy of Sciences, report that magnetic field fluctuations may play a role in health outcomes. They describe the disturbances as having amplitude and frequency, which can interact with organ rhythms. When the magnetic field oscillates at a rate similar to those of key organs, a tuning fork effect can occur. Studies on strokes and heart attacks have shown a potential pattern: magnetic field changes lasting about one to two seconds during storms may coincide with cardiac stress, potentially contributing to cardiovascular events such as heart attacks or strokes.
Because all cells follow a rhythmic pattern, geomagnetic disturbances can disrupt this harmony and may affect cardiovascular, musculoskeletal, and even mental health states on a three-hour cycle. The idea that solar activity could influence broad human behavior is not new; Chizhevsky proposed that solar cycles might affect collective thought, a hypothesis that Breus notes has been explored in recent work.
The team behind this line of inquiry analyzed language use in a large dataset of forum posts. Over 11,000 messages were processed by a specialized bot, revealing correlations between geomagnetic activity, measured by the Kp index, and the frequency of terms related to fundamental concepts in quantum mechanics, relativity, and related ideas. The analysis found peaks in discussions about these topics on days with higher Kp values, suggesting a potential link between space weather and cognitive or philosophical discourse in certain environments.
In cardiovascular terms, magnetic disturbances can cause red blood cells to clump together, narrowing vessels and elevating blood pressure. Some studies have estimated that magnetic storms may contribute thousands of heart attacks and strokes annually, underscoring the potential risk for those with existing cardiovascular conditions. Breus notes that heart rate can be affected during storms, with potential tachycardia, bradycardia, or arrhythmias, particularly in individuals with serious heart issues.
Space weather also influences the musculoskeletal system. Since bones receive blood supply, inflammation or pain in joints may intensify during magnetic storms, especially for those with preexisting joint conditions. Breus adds that our surroundings can influence these rhythms too, though the overall effect remains tied to the body’s internal timing rather than external forces alone.
Airborne forces and rhythmic variations in the environment are part of the broader picture. The idea that magnetic fields shape biological rhythms persists, though its practical effects can vary from person to person and depend on overall health and resilience.

The risk magnetic storms pose to an individual depends on health status, time of day, season, and location. Breus notes that intense storms tend to be stronger at higher latitudes, while equatorial regions experience them less frequently. People living closer to the poles often report more noticeable effects from space weather.
Magnetic disturbances follow a seasonal pattern, typically peaking in the March-April window and diminishing during the summer and winter. The Sun’s influence itself reaches a daily peak around noon, which Breus identifies as a period of greater potential impact.
Children may not notice the effects, but sensitivity rises with age. Elderly individuals and infants are among the most vulnerable groups, with some studies indicating a higher risk of adverse events during strong magnetic storms for these populations. Kleimenova emphasizes that people with existing health issues should be particularly mindful of geomagnetic changes.
There are divergent views on the magnitude of magnetic storms’ effects. Some researchers argue that storms are relatively weak perturbations and that other factors often play a larger role in health outcomes. There is evidence from experiments conducted in various environments, including extreme latitudes, showing mixed results in terms of physiological changes. In general, the consensus is that individuals with compromised health are more likely to experience noticeable effects during geomagnetic disturbances.
Just a coincidence?
Despite ongoing research, a portion of the scientific community remains skeptical about the degree to which a person depends on weather. Some scientists argue that urban noise and activity introduce greater magnetic fluctuations than storms. Yet, there are statistics showing a rise in ambulance calls during magnetic disturbances, suggesting a measurable, if nuanced, impact in real-world settings.
Vyacheslav Pilipenko of the Gazete.Ru Institute for Earth Physics notes that industrial activity can produce stronger magnetic perturbations than magnetospheric storms, while the biological consequences of storms still appear in some cases. The effect may not touch everyone, but it is possible for certain borderline cases to experience noticeable responses, particularly during strong events.
Cardiologist Anton Rodionov from Sechenov University argues that weather itself is not a direct risk factor. He points out that health outcomes depend on the presence of disease and the body’s ability to adapt. Normal functioning may withstand weather shifts, but a sick person may be more susceptible to disturbances in atmospheric conditions.
