Hot air linked to headaches, but how? - CNN.com: "Headaches, big and small, are among the most common health complaints. Almost 90 percent of women and about 70 percent of men get tension headaches, the Mayo Clinic says. Yet doctors still don't know much about what causes them.
About 18 percent of women and 6 percent of men in the United States report having migraines.

About 18 percent of women and 6 percent of men in the United States report having migraines.

In a new large-scale study published in the journal Neurology this week, researchers found that higher temperatures and, to a lesser extent, low air pressure, influence severe headaches.

But researchers aren't sure how temperature influences headaches, and others say that a slew of other factors could be involved in the connection.

'I think it's more complicated than that,' said Dr. Joel Saper, director of the Michigan Head Pain and Neurological Institute in Ann Arbor, Michigan, who was not involved in the study. Temperature and pressure may be indirect evidence of other causal factors."
