The study found a shocking 31 percent increase of the risk of headache and a 28 percent increased risk of migraine for chronic headache sufferers on days that lightning struck within 25 miles (40 kilometers) of their homes. … Furthermore, new-onset headaches and migraines increased by 24 percent and 23 percent, respectively, according to the study, published January 24 in the headache-focused journal Cephalalgia.
While there have been conflicting studies linking factors such as weather, humidity, and barometric pressure and headaches, the new study is the first to show a correlation between lightning and associated weather phenomena and the squalls in our heads. …
Participants in the study logged their daily headache activity for three to six months, during which any nearby lightning strikes were also recorded. Mathematical models were then applied to rule out other weather factors as the cause of the headaches–and the correlation held true. … results “suggest that lightning has its own unique effect on headache,” study leader Vincent Martin, a professor of medicine at the University of Cincinnati, said in a statement. …
“Electromagnetic waves emitted from lightning could trigger headaches. In addition, lightning produces increases in air pollutants like ozone, and can cause release of fungal spores that might lead to migraine.” … “the exact mechanisms through which lightning and/or its associated meteorologic factors trigger headache are unknown.” …
