Geomagnetic storms aren't just beautiful to look at — these disturbances in the Earth's magnetic field could also be messing with your mind and body. There's a ton of evidence suggesting that geomagnetic storms can cause everything from depression to cardiac problems — and may even be influencing the stock market.
A new paper suggests there's a lot more evidence for this connection than anybody realizes. We talked to the paper's author, and here's what he told us.

The paper, published in the Proceedings of the Royal Society B, argues that there's a large, disparate, and controversial body of scientific literature that links geomagnetic storms to a number of animal behaviors, including cardiovascular, psychiatric and behavioral changes in humans. And author Dr. James Close has the enormous literature review to back up his claims.
Close, a researcher with Isis Green, tells io9 that he stumbled into the topic of geomagnetic storms and human behavior, when he read a paper published by the Atlanta Federal Reserve (PDF) entitled "Playing the Field: Geomagnetic Storms and the Stock Market."
Close says he was skeptical at first:
Was this paper just a spurious, one-off finding, or was there a backdrop of corroborating evidence concerning behavioural changes in association with geomagnetic storms? The whole notion of geomagnetic storms influencing human behaviour seems so "wacky" that a very strong body of evidence is required before taking it seriously.
And then he started looking into the evidence, and "the whole thing kind of ran away with itself," says Close, who has a PhD from Oxford and a background hematology and psychiatry. Soon enough, he found way more supporting evidence than he ever expected — much of it in Russian, and thus relatively unknown to English-speaking researchers.
How could it work?
The argument for a connection between geomagnetic storms (GMS) and behavior ties in with an evolutionary leftover humans that may have — the ability to detect magnetic fields through cryptochromes. There's research tying geomagnetic activity to human health.
