The geomagnetic storm on August 13 is a natural phenomenon that may impact the health and mood of many people. According to forecasts from space observatories, this day is expected to bring elevated solar activity with a G2 level, considered moderate but capable of producing noticeable effects. These may include headaches, fatigue, blood pressure fluctuations, and reduced concentration. The storm can also affect communications, navigation systems, and power grids. People with chronic heart and nervous system conditions are particularly sensitive. Read more at Baltimore Chronicle.
What is a geomagnetic storm and how is it predicted
A geomagnetic storm is the Earth’s magnetic field reacting to streams of charged particles from the Sun. Its impact is measured on a scale from G1 (minor) to G5 (extreme). Forecasts are based on observations of sunspots, coronal mass ejections, and solar wind speed. In August 2025, solar activity is at the peak of its 11-year cycle, which explains the increased frequency of flares.
How geomagnetic storms affect the human body
Doctors note that geomagnetic disturbances can raise blood pressure, alter heart rates, cause sleep problems, and trigger irritability. Those with cardiovascular conditions face higher risks of hypertensive crises and arrhythmias. Psychologists warn of increased anxiety levels. To reduce the negative impact, experts advise avoiding excessive physical exertion, staying hydrated, and limiting caffeine and alcohol.
Possible symptoms during the storm:
- Headache or migraine
- Dizziness
- Rapid fatigue
- Sleep disturbances
- Mood swings
Geomagnetic storm forecast for August 2025
Astronomical services have created an activity calendar for August, indicating impact levels. This helps people, especially the weather-sensitive, plan important activities.
| Date | Storm Level | Impact on People and Technology |
|---|---|---|
| August 13 | G2 | Moderate impact, possible sleep disruption |
| August 17 | G1 | Minor fluctuations, weak impact |
| August 23 | G3 | Strong impact, GPS and navigation issues |
How to prepare for a geomagnetic storm
Experts recommend adjusting your schedule in advance, avoiding heavy physical and emotional stress, and ensuring adequate rest. Sensitive individuals should keep necessary medication handy and spend more time outdoors.
Tips for the storm day:
- Drink water in small portions throughout the day.
- Eat light meals rich in magnesium and potassium.
- Avoid stressful situations and arguments.
- Limit screen time in the evening.
- Take a short walk before bed.
Impact on technology and communications
Moderate and strong storms can cause satellite communication issues, GPS malfunctions, and short-wave radio interference. Power companies sometimes report voltage fluctuations. While these effects are minor in everyday life, airlines and navigation services account for them in their operations.
