The second half of May 2026 will bring a series of powerful geomagnetic disturbances. Solar activity will reach peak levels, forcing weather-sensitive people and those with chronic illnesses to be especially careful.
RBC-Ukraine, citing Space Weather Prediction Center, shares a detailed storm calendar and advice on how to protect blood vessels during this period.
Magnetic storm calendar: Detailed forecast
According to astrophysicists’ forecasts, space weather from May 11 to 15 will remain highly unstable:
May 11. Activity begins. The disturbance level will reach 4 points. Possible symptoms include apathy, rapid fatigue, and trouble concentrating.
May 12-13. Geostorm peak. The storm will intensify to 5 points (red level). This is a critical level that may trigger severe migraine attacks and blood pressure spikes.
May 14. The storm will gradually weaken, though activity will remain at 3-4 points. The body may experience overall exhaustion.
May 15. The magnetosphere will stabilize. Indicators will return to normal, allowing the body to begin recovery.
What is a magnetic storm?
When solar flares erupt on the Sun, clouds of charged particles are released toward Earth. Their collision with the planet’s magnetic field causes disturbances in the atmosphere. This not only creates auroras but may also affect blood viscosity and the human nervous system.
Who is at greatest risk?
A red-level geostorm (5 points) may pose risks for:
- People recovering from surgery
- Weather-sensitive individuals
- Those with cardiovascular disease or hypertension
- Elderly people and pregnant women
- People experiencing chronic stress or severe fatigue
Most common symptoms
During peak solar activity on May 12-13, people may experience:
- Headaches: from mild pressure in the temples to intense migraines
- Blood pressure fluctuations: sudden spikes even in otherwise healthy individuals
- Weakness: feelings of heaviness and joint aches
- Sleep problems: insomnia or overwhelming daytime drowsiness
- Anxiety: inner tension without an obvious reason
How to protect yourself: experts’ advice
To reduce the impact of magnetic storms on the body, doctors recommend:
Avoid stimulants. Coffee, strong tea, and alcohol can overload blood vessels during these days.
Stay hydrated. Drink more still water to help thin the blood and reduce strain on the heart.
Reduce physical activity. Skip intense workouts. A slow walk in the park is a better option.
Follow a lighter diet. Cutting back on salty foods may help prevent fluid retention and swelling.
Keep medication nearby. Make sure blood pressure or headache medicine is within reach.
