Mild temperatures and atmospheric pressure changes can cause headaches and migraines, compared with the pollution, researchers said, in London.
A team of U.S. researchers showed that every time the temperature rose 5 degrees Celsius (about 9 degrees Fahrenheit), it seems to increase the risk of severe headaches for almost 8%, compared with days when the weather is cooler.
Air temperature, humidity and barometric pressure is often cited as reasons for a headache but so far not much evidence to support that opinion, said Kenneth Mukamal of Beth Israel Deaconess Medical Center in Boston and colleagues. The team studied more than 7,000 men and women who were diagnosed with headache or migraine, in a hospital emergency room between May 2000 and December 2007.

They use meteorology and pollutant monitoring in order to analyze the air temperature, air pressure, humidity, particulate matter healthy, black carbon and sulfur dioxide for three days before the visit to the hospital and then afterwards.
"In other words, the design of our study to directly compare the weather and air pollution conditions just before a visit to the emergency room with the same factors are measured at the beginning and end of the same month," said Mukamal.
The study found that of all the studied environmental factors, air temperature higher is required to exclude it as a problem, researchers said.
The findings are published in the journal Neurology shows, weekly forecasts to help people prepare their treatment in order to ward off headaches
