When lightning strikes, so may a headache.
Past research has shown weather elements like barometric pressure can trigger headaches and migraines, but a new study specifically links lightning to the onset of headaches, regardless of other weather factors associated with storms.
Researchers followed a group of migraine sufferers, asking them to record their headache activity for three to six months.
They found there was a 31% increased risk of headache and 28% increased risk of migraine on days lightning struck within 25 miles of a person's home.
Experts speculate that electromagnetic waves from lightning may be to blame but also point out that lightning increases air pollutants in the air, which could lead to migraine.
