This study examined the relationship between weather and headache risk. The study’s scope could not include air pollution, which has been implicated in other diagnoses.

“Many migraine sufferers will tell you they don’t need a weatherman to tell them the forecast; their headaches signal what is coming. But there has been little scientific evidence to link the two – until now.

“Researchers from Beth Israel Deaconess Medical Center – who studied 7,000 emergency-room visitors over a seven-year period – reported yesterday that headache-related hospital visits increased in the 24 hours after air temperatures rose. Lower barometric pressure in the 48 to 72 hours before a patient’s arrival was also associated with a higher risk of headache.”

…”The study appears today in the journal Neurology. Much larger studies have implicated air pollution in cardiovascular disease and respiratory illnesses, such as asthma. Previously, two small Canadian studies looking at weather and headaches had conflicting results.”
