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 much lower latitudes than usual — during strong storms the northern lights have been seen across the northern US, the UK, and central Europe.

Q: Where does the data come from?

From NOAA SWPC — the US Space Weather Prediction Center. It's the global standard for measuring geomagnetic storms via the Kp index. Updates every 10 minutes.

Q: Is this medical advice?

No. This is an informational site showing geomagnetic activity data. For serious symptoms, see a doctor — not a website.

What is a geomagnetic storm?

A geomagnetic (magnetic) storm is a temporary disturbance of Earth's magnetic field driven by charged particles from the Sun — solar flares and coronal mass ejections. Storm strength is measured by the Kp index on a 0–9 scale: the higher the value, the stronger the disturbance. Kp 5 and above corresponds to NOAA storm levels G1–G5.

Most people feel nothing. Weather-sensitive individuals — often older people or those with high blood pressure — may report headaches, fatigue, blood-pressure swings, and disrupted sleep, especially at Kp 5+. More on symptoms and what to do →

Kp scale and storm levels G1–G5

Kp	Level	What it means
0–2	—	Quiet. No effect on wellbeing.
3	—	Unsettled. Barely noticeable.
4	—	Active field. The most sensitive may feel it.
5	G1	Minor storm. Possible headaches, fatigue. Aurora at high latitudes.
6	G2	Moderate storm. Pressure swings in sensitive people.
7	G3	Strong storm. Aurora visible at mid-latitudes.
8	G4	Severe storm. Possible GPS and radio disruption.
9	G5	Extreme storm. Aurora seen far toward the equator.

What to do during a geomagnetic storm?

Drink more water — it helps with blood-pressure swings.
Cut coffee and alcohol, especially at Kp 5 and above.
Go to bed earlier and rest more.
Don't schedule big decisions for the storm peak.

Why don't I feel anything?

Most people don't. If you're among the storm-sensitive, you usually notice. If not — lucky you.
