Why don't I feel anything during a magnetic storm?

Most people don't feel the effects of geomagnetic storms. Sensitive individuals — typically older people or those with hypertension or autonomic dysfunction — may experience headaches, fatigue, or blood pressure fluctuations. It's a real effect, not imagined.

What is the Kp index?

Kp is a planetary index of geomagnetic activity measured over a 3-hour interval on a scale of 0 to 9. Values 0-3 are quiet, 4 is a mild storm, 5-6 is notable, 7-9 is severe with potential aurora visibility at lower latitudes including northern Ukraine.

What is this?

Geomagnetic storms are fluctuations of Earth's magnetic field caused by solar flares. The higher the Kp index (0–9), the stronger the storm. Some people feel them as headaches, fatigue, or pressure swings.

What to do?

Drink more water.
Less coffee and alcohol.
Go to bed earlier.
Don't plan big decisions at storm peak.
