Powerful magnetic storms will hit the Earth: the schedule for October 2025

Magnetic storms, which are the result of solar flares, are expected to cover the Earth in early October. On Sunday, September 28, the most powerful pulse flare of the M6 class in the last three months occurred on the star closest to us.4. In general, there is increased activity in the Sun, the consequences of which are still difficult to speak with certainty, experts say. However, on October 2, a G1-level magnetic storm hit our planet. For more information about the cosmic phenomenon, as well as how to protect yourself from its effects, see the Izvestia article.

Geomagnetic storms in October 2025: graph

The occurrence of geomagnetic, or magnetic, storms on Earth depends on solar flares, which, despite the development of technology, are still difficult to predict. Because of this, forecasts are made based on historical data or indirect indicators of the star's activity. Because of this, notifications of approaching magnetic storms come only after an outbreak has already occurred on the Earth—Sun line. Nevertheless, experts make forecasts that help to give an approximate assessment of space weather, as well as indicate the days when increased geomagnetic activity is possible.

According to some forecasts, there may be several periods before the end of October when geomagnetic activity will be unstable, there is a possibility of storms of G1 level or higher.

There are five levels of intensity of magnetic storms.:

— G1 (weak storm). There may be small errors in the operation of artificial satellites. During the solar cycle (about 11 years) occur about 1,700 times.;

— G2 (moderate storm). Voltage fluctuations, radio interference, and damage to transformers may occur. Occur about 660 times per cycle;

— G3 (severe storm). It occurs about 200 times in 11 years and can cause satellite navigation problems.;

— G4 (very strong or severe storm). In such storms, electric currents can be generated in metal objects and wires, and protective devices are triggered by mistake. It happens about 100 times per cycle;

— G5 (extremely strong storm). Such storms are extremely rare and occur no more than four times per cycle. They cause serious disruptions in the operation of satellites and power grids, up to a complete shutdown.

It is estimated that the nearest most likely intensification of geomagnetic storms may occur as early as October 2, and it will last for six days. According to forecasts, the storm will reach the G1 level, after which an excited magnetosphere will remain until the 6th.

Magnetic storms in July: a strong wave will cover the Earth more than once before the end of the month

They won't be extreme.

Magnetic storms in October 2025: what health problems to expect

Recent research in the field of heliobiology (a branch of biophysics that studies the effects of changes in solar activity on terrestrial organisms) reveals correlations between geomagnetic activity and its effects on some people. Chronic diseases may occur, especially cardiovascular, neurological, and psychophysiological ones. Below are the main risks and manifestations that are worth paying attention to.

Cardiovascular problems

— Increased blood pressure. A number of studies have shown a link between geomagnetic activity and pressure in humans. However, some scientists believe that its growth could be related to other phenomena, such as changes in the weather.

— Increased risk of seizures, including angina pectoris, arrhythmias, and exacerbations in people with heart failure.

— Some studies have noted an increase in the death rate from heart disease during severe geomagnetic disturbances.

Neurological and psychoemotional effects

— Headache, migraine, dizziness.

— Sleep disorders: difficulty falling asleep, intermittent sleep, feeling tired even after sufficient rest.

— Decreased concentration, irritability, mood swings.

Exacerbation of chronic diseases

— Deterioration of health can be observed in people with hypertension, coronary artery disease, varicose veins, and diseases of the cerebral vessels.

— Decreased immune defenses, a general feeling of weakness, and possibly a deterioration in well-being with colds and viral diseases.

Other possible manifestations

— Increased anxiety, anxiety.

— Problems with the vestibular apparatus, some have nausea, coordination disorders.

It is believed that the elderly (over 60 years old) are most susceptible to the effects of magnetic storms, especially in the presence of chronic diseases; people with cardiovascular, neurological and mental illnesses.

Scientific articles emphasize that the impact of magnetic storms on health is often indirect. Changes in health status may depend on many other factors: stress, sleep disorders, and the weather. The direct cause-and-effect relationship is still the subject of active research.

Often, the cause of the influence of magnetic storms on a person is a psychosomatic reaction — in anticipation of negative consequences, as well as knowing about approaching cosmic events, people may feel physically unwell.

Scientists warn: the strongest magnetic storm in two months is coming.

Magnetic storms in October 2025: how to deal with negative influences

To minimize possible negative effects on the body during geomagnetic storms, it is useful to follow a number of practical recommendations.:

— sleep and mode. It is important to get a good night's sleep — at least 7-8 hours, with regular bedtime and wake-up time. An hour or two before falling asleep, it is recommended to limit screen time, especially blue and bright light, as well as stimulating activities.;

— load limitation. Physical activity should be moderate. Doctors advise weather-dependent people to avoid intense workouts on days of intense space activity. Experts also recommend practicing breathing exercises, yoga, or meditation.;

— power control. Especially in the evening, it is worth excluding coffee, strong tea and energy drinks. It is also important to limit the consumption of alcohol, heavy and fatty foods. It is better to stick to proper nutrition and a healthy lifestyle (not only during the days of magnetic storms);

— maintaining health. People who are aware of their weather sensitivity are advised to regularly measure blood pressure, especially if they have hypertension or heart disease. It is also important to prepare all necessary (exclusively prescribed by a doctor) medications in advance. You can also pay attention to symptoms such as chest pain, shortness of breath, and palpitations. You can not self-medicate, if any symptoms appear, you need to consult a specialist.;

— the external environment. On days of magnetic storms, it is worth ventilating the room and maintaining a comfortable temperature and humidity.

— information readiness. Weather-dependent people can monitor the forecast of magnetic storms and prepare for them in advance.

If any symptoms occur, consult a doctor and do not take medications without prescription.
