Most migraine sufferers believe that weather changes can bring on

their headaches, but the scientific proof has been lacking -- until

now.

New research suggests that certain weather conditions may trigger

migraines and other severe headaches. But frequent sufferers may be

surprised by some of the findings.

The study reveals that:

Regardless of the time of year, an increase in temperature was the

biggest weather-related headache trigger. Researchers reported that

every 9 degree Fahrenheit increase in temperature raised the headache

risk by 7.5%.

Low barometric air pressure is considered by some to be specific to

migraines, but the study found no link between migraines and

low-pressure systems. The researchers say lower pressure was

associated with a small increase in risk for non-migraine headaches.

Air pollution was not strongly associated with an increased risk for

migraine or non-migraine headaches. But the automobile exhaust

pollutant nitrogen dioxide did show a borderline effect on

non-migraine headaches.
