Everyone has long known that Magnetic storms increase blood pressure and risks for the heart. Many scientific studies have been conducted where it is said (especially relevant scientific studies of 2021–2025) even weak geomagnetic storms can cause pressure jumps of 2–8 mm Hg. and increase the likelihood of arrhythmia and heart attacks. So the question arises: Who is at risk and how to protect the cardiovascular system
Everyone has long known that Magnetic Storms increase blood pressure and heart risks. Many scientific studies have been conducted that say (especially relevant scientific studies from 2021–2025) that even weak geomagnetic storms can cause pressure jumps of 2–8 mm Hg and increase the likelihood of arrhythmia and heart attacks.
So the question arises: Who is at risk and how to protect the cardiovascular system in 2026? We will analyze this in this article below, edited by Ukrainian Information, together with involved medical specialists, based on real scientific studies with links to them, so that you can check it yourself.
It is important to note right away: Correlation does not always mean direct causation. Human health is a complex living organism where everything is interconnected, so heart and blood pressure problems do not always directly depend on solar flares. For details and clarification of the causes of your health problem, consult a cardiologist.
Let’s get started. Studies show a statistically significant effect of geomagnetic storms on the cardiovascular system, but the reaction of each organism is individual. This article does not replace a doctor’s consultation. If you have problems with blood pressure or heart, be sure to consult a cardiologist or other doctor with a referral from your family doctor.
Why the topic of solar flares and heart and blood pressure problems in people is relevant right now
2026 is not only the 5th year of a full-scale invasion with its stress and all the resulting consequences of war, but also the peak of solar activity Solar Cycle 25 , and in general, geomagnetic storms have become more frequent in recent crusts. Thousands of Ukrainians are daily looking for answers to the questions impact of magnetic storms on blood pressure and heart , magnetic storms and blood pressure and health problems from magnetic storms .
Statistics show: on days of even weak storms (G1–G2), the number of visits with hypertensive crises and arrhythmias increases by 15–40%. Recent studies from 2024–2025 ( Nature Communications Medicine, PMC ) confirm: geomagnetic storms have a statistically significant effect on the cardiovascular system.
In this article, we will analyze the scientific evidence, mechanisms of influence, and practical recommendations from cardiologists. This is the most comprehensive review in Ukrainian for 2026.
What are magnetic storms and how do they affect the human body?
Magnetic storms (geomagnetic storms) are disturbances in the Earth’s magnetosphere caused by solar wind and coronal mass ejections (CMEs). The NOAA Space Weather Prediction Center classifies them on a scale of G1–G5 based on the Kp index (5 to 9).
In simple terms, magnetic storms: The Sun “spits out” charged particles, they reach Earth in 1–3 days and “shake” our magnetic field. This affects not only technology, but also living organisms.
The scientific explanation for magnetic storms: Changes in the geomagnetic field affect heart rate variability (HRV), melatonin levels, and the autonomic nervous system. Studies show that even weak storms (G1) can trigger a reaction in sensitive people.
Scientific evidence of the effect on blood pressure
Many studies confirm: magnetic storms increase pressure .
- The results of the study by Dimitrova S. et al., 2004 (PubMed 15300726): confirm that during local geomagnetic storms, blood pressure increased in most volunteers who participated in the study. Link to the scientific study: https://pubmed.ncbi.nlm.nih.gov/15300726/
- Conclusions based on the results of Wang VA et al., 2021 (Journal of the American Heart Association): In 675 elderly men, solar activity and Kp-index were associated with an increase in systolic blood pressure by 2.1–2.7 mm Hg and diastolic blood pressure by 1.7–2.8 mm Hg. The effect, according to the study, is strongest 16–28 days after the peak of activity. Link to the source of the study https://pubmed.ncbi.nlm.nih.gov/34713707/
- Data – Mayrovitz HN, 2023 (PMC10589055): A review of 20+ studies and analysis of the results showed an increase in systolic and diastolic pressure by 3–8 mm Hg during geomagnetic storms. In addition, systolic pressure responds more often. In hypertensive patients, the increase reaches 7 mm Hg. https://pmc.ncbi.nlm.nih.gov/articles/PMC10589055/
- Recent study from 2025 (Nature Communications Medicine, s43856-025-00822-w): A recent study at mid-latitudes found that geomagnetic activity has a statistically significant effect on blood pressure fluctuations, especially during severe storms.

Comparison table of studies on the impact on pressure:
| Research | Year | Increased systolic pressure | Increased diastolic pressure | Group of participants |
|---|---|---|---|---|
| Dimitrova et al. | 2004 | + a few mm Hg. | + a few mm Hg. | General population |
| Wang et al. | 2021 | +2.1–2.7 mmHg | +1.7–2.8 mmHg | Elderly men |
| Mayrovitz (review) | 2023 | +3–8 mmHg | +3–8 mmHg | Hypertensive + norm |
| Nature Comm. Med. | 2025 | statistically significant | statistically significant | Mid-latitudes |
The effect of magnetic storms on the heart, causing: arrhythmias, heart attacks, heart failure
Geomagnetic storms and the heart are not a myth. Studies show an increase in risks:
- A 2025 study (Nature, s43856-025-00887-7): Geomagnetic disturbances increase the risk of myocardial infarction in women and men in Brazil. These results are confirmed by: https://www.nature.com/articles/s43856-025-00887-7
- Separately, it is worth mentioning PMC12005662, the previous 2025 , where Geomagnetic storms increase the risk of myocardial infarction. Read the argument in more detail in the study below – https://pmc.ncbi.nlm.nih.gov/articles/PMC12005662/
- Older works (PubMed 12653177, 16075902) have shown changes in cardiovascular parameters and disruption of homeostasis during global and local geomagnetic activity.
That is, we can logically judge the “Effect,” namely, a decrease in heart rate variability (HRV), which increases the risk of arrhythmias.
Who is most sensitive to magnetic storms and why: the elderly, hypertensive patients, women, pregnant women
The highest risk is in:
- people over 60 years of age (according to the results of the Wang 2021 study);
- patients with hypertension (according to the results of the Mayrovitz 2023 study – namely due to increased sensitivity);
- women (Data – Nature 2025 — the stronger effect is on heart attacks);
- pregnant women (increased pressure may affect the fetus).
Less sensitive than usual are young, healthy men.
Mechanisms of influence
- Changes in heart rate variability (HRV) lead to a decrease in parasympathetic activity.
- Disruption of melatonin synthesis is a side effect of the effect on the pineal gland.
- Activation of the autonomic nervous system — sympathetic imbalance as a direct consequence.
Therefore, these studies, through the mechanisms listed above, directly explain how magnetic storms affect the cardiovascular system .
What does Statistics say in Ukraine and the world?
In the world as a whole, on days of G1–G3 storms, the number of hospitalizations with hypertensive crises increases by 20–30%. In Ukraine, cardiologists record similar dynamics and support this opinion, since during solar maxima (data from the Ministry of Health and clinical observations 2024–2026) the flow of patients is higher.
How to protect the heart and blood pressure during magnetic storms?
We have prepared these practical recommendations based on the recommendations of cardiologists of Ukraine with scientific justification:
- Blood pressure monitoring – measure 3-4 times a day during dangerous periods, as monitoring is a prevention of complications.
- Medications – do not change the dose yourself, but keep your medications on hand (as prescribed by your doctor).
- The regimen is 7–9 hours of sleep, limiting caffeine and alcohol (reduces blood pressure).
- Nutrition — magnesium (bananas, nuts), potassium, omega-3.
- Physical activity – light walks, avoid intense exercise (to prevent blood pressure from rising).
- Relaxation – breathing techniques, meditation (improve HRV).

Myths and reality
Many doctors say “it’s a myth” because not all people react. But meta-analyses (Mayrovitz 2023, Nature 2025) show a statistically significant correlation. Scientific studies of magnetic storms and pressure prove: there is an effect, just not for everyone.
Conclusion + recommendations for 2026
The impact of magnetic storms on blood pressure and the heart is a real risk factor in 2026. Scientific evidence (from Dimitrova 2004 to studies in 2025) confirms an increase in blood pressure by 2–8 mm Hg, an increase in the risk of arrhythmias and heart attacks.
Recommendations for 2026 :
- Subscribe to the magnetic storm forecast (NOAA, SpaceWeatherLive).
- Keep a blood pressure diary.
- Get a check-up with a cardiologist.
