In October 2025, the Earth is expected to experience high geomagnetic activity in several periods. Scientists have already determined when to expect dangerous storms that may affect people's well-being and the operation of equipment. Here is the exact forecast, along with the doctors' advice.
Calendar of magnetic storms for October
Experts predict several waves of disturbances in the Earth's magnetic field. They will be most noticeable in the first and second ten-day periods of the month.
October 3-4: a moderate storm is expected, which may affect meteorosensitive people
October 6: moderate storm
October 10-12: a powerful red-level magnetic storm
October 16-17: moderate activity, deterioration of well-being is likely on these days
October 19-20: strong magnetic storm
October 25: moderate disturbances are forecast
Additionally, short periods of activity are possible on October 11 and 20.
Who is at risk
Geomagnetic fluctuations affect people differently. The most sensitive to storms are:
- People with heart and vascular diseases
- People with hypertension
- Elderly people
- Weather-dependent and meteorosensitive people
- Pregnant women
- Patients with chronic neurological and endocrine diseases
These groups may experience headaches, fatigue, fluctuations in blood pressure, and insomnia.
How to protect yourself during magnetic storms
Doctors recommend following simple rules to better cope with periods of solar activity:
- Sleep at least 7-8 hours
- Drink enough water and avoid alcohol, energy drinks, and excessive coffee
- Eat light food, more vegetables and fruits, and less salty and fatty foods
- Take walks in the fresh air, and avoid heavy physical exertion
- Take medications on schedule, especially cardiovascular drugs
- Reduce stress levels, avoid overwork
- Monitor the space weather forecast
- On days of magnetic storms, plan your day more calmly so as not to provoke exacerbations of chronic conditions.
What a geomagnetic storm is
Solar flares (also solar storms or geomagnetic storms) are internal reactions of the Sun, including coronal mass ejections and surface flares, which release energy in all directions.
When this energy reaches the Earth and collides with our magnetosphere, it triggers geomagnetic activity. Magnetic storms are classified into five levels:
G1 is the weakest, affects sensitive people, and can cause minor technical glitches.
G5 is the strongest, capable of disabling equipment and power systems and seriously worsening health.
