Magnetic storms are natural phenomena that can affect not only technical systems but also human health. On June 18, 2025, one of the most powerful geomagnetic storms of the month is expected, with warnings already coming from scientists around the world. Experts recommend preparing in advance for potential changes in well-being and technical disruptions. As the Baltimore Chronicle notes, this date is of particular concern to researchers due to the level of solar activity.
What is a magnetic storm and why does it occur
A magnetic storm is a disturbance of Earth’s magnetic field caused by interactions with the solar wind. When solar flares occur on the Sun, they eject clouds of charged particles that reach our planet in 1–3 days. These particles interact with Earth’s magnetosphere, triggering geomagnetic disturbances.
Main causes of magnetic storms:
- Solar flares (especially class X)
- Coronal mass ejections (CME)
- High-speed solar wind streams from coronal holes
Storms most often occur during periods of increased solar activity, which can last for several years. We are currently in the rising phase of the solar cycle, which explains the increased frequency of geomagnetic storms.
Magnetic storm forecast for June 18
According to preliminary data, the magnetic storm on June 18 is expected to reach level G3 (moderately strong) or even G4 (strong). This means not only weather-sensitive people may feel unwell, but technical systems such as satellites, radio communication, and GPS may also be disrupted.
Key storm characteristics:
- Level: G3–G4
- Activity begins: morning of June 18
- Storm peak: afternoon
- Expected duration: up to 20 hours
The magnetosphere will remain unstable for several days afterward, so “echoes” of the storm may still be felt on June 19–20.
How magnetic storms affect human health
People react to magnetic storms differently. Those with chronic cardiovascular or nervous system conditions, as well as weather-sensitive individuals, are especially vulnerable.
Most common symptoms:
- Headache, migraine
- Dizziness, fatigue
- Elevated blood pressure
- Sleep disturbances
- Anxiety, irritability
At-risk groups:
- People with high or low blood pressure
- Individuals with heart rhythm disorders
- Pregnant women
- Elderly people
- Those with vegetative-vascular dystonia
Experts recommend monitoring your health and consulting a doctor if needed.
What to do to ease symptoms during a magnetic storm
There are simple steps you can take to reduce the storm’s impact on your body:
- Drink plenty of water
- Avoid alcohol and caffeine
- Limit physical exertion
- Get more rest
- Take mild sedatives (only as prescribed)
You should also reduce screen time and avoid stressful situations.
Things to keep with you:
- A bottle of water
- Essential medications
- Elastic bandages or a blood pressure monitor
- Light snacks (nuts, bananas)
How storms affect technology and infrastructure
Magnetic storms can disrupt:
- Radio communication and internet
- Satellite navigation (GPS)
- Aviation systems
- Power grids (especially in northern regions)
For regular users, this may lead to:
- Mobile network outages
- Banking transaction failures
- Lost navigation signals
Drivers and airline passengers should be especially cautious on days with high geomagnetic activity.
Comparison of geomagnetic storms in recent months
| Date | Storm Level | Duration | Health Impact | Technical Disruptions |
|---|---|---|---|---|
| April 10 | G2 | 14 hours | Moderate | Minimal |
| May 3 | G3 | 17 hours | Significant | Moderate |
| June 18 | G3–G4 | Up to 20 h | Strong | Likely |
These data show that June 18 may be the most intense day in recent months.
How to prepare for the magnetic storm in advance
To minimize risks, consider:
- Planning your day with potential weakness in mind
- Stocking up on needed medications
- Preparing appliances for possible power outages
- Charging batteries and power banks
- Staying calm and avoiding panic
For office workers:
- Avoid overworking
- Take a walk during lunch
- Limit caffeine intake
For parents:
- Monitor children’s moods
- Reduce screen time
- Spend more time outdoors
Is the June 18 storm dangerous for Ukrainians?
Although Ukraine is not in a high-risk zone for power grid failures, the magnetic storm will still affect vulnerable populations. This especially applies to:
- Hospital patients
- Drivers planning long trips
- People working with technical systems or data
Experts assure that the storm will not cause disasters, but everyone should stay informed and prepared.
