If you've ever blamed the weather for a splitting headache, you
might be right. A new University of Cincinnati study finds that
lightning may affect the onset of headache and migraines. "What
we found was that on days with lightning around the patients'
homes there was approximately a 30-percent increase in headache
activity, or headache occurrence, and also a 30-percent increase
in migraine," said fourth-year medical student Geoff Martin, one
of the researchers. The study looked at chronic headache
sufferers. There are a number of ways lightning might be a
trigger.
