Scientists at the University of Cincinnati say the link between the sometimes debilitating conditions and nearby thunderstorms is profound.
“Many studies show conflicting findings on how weather, including elements like barometric pressure and humidity, affect the onset of headaches,” said Geoffrey Martin, who conducted the research with his father, Vincent.
“But this study very clearly shows a correlation between lightning, associated meteorological factors and headaches.”
The scientists aren't exactly sure how lightning and headaches are related, but research suggests the electromagnetic waves or increased ozone from the lightning could be the culprits.
The researchers compared symptoms outlined by the International Headache Society with where lightning struck within 25 miles of a participant's homes.
They also looked at the magnitude and polarity of lightning currents believed responsible for the headaches.
