Do Air Pollution and Weather Trigger Headaches?
Story by: Guest Contributor First posted on 03-11-2009 A new study shows that higher temperatures and lower barometric air pressure may lead to a higher, short-term risk of headaches, but air pollution may not have a significant effect on headache. The research is published in the March 10, 2009, print issue of Neurology®, the medical journal of the American Academy of Neurology. For the study, researchers looked at 7,054 people who were diagnosed with headache in a Boston emergency department over seven years. Scientists then compared temperature levels, barometric pressure, humidity and other air pollutant or weather factors during one to three days leading up to the hospital visit. The study found that higher temperatures increased the risk of headache. The risk went up by 7.5 percent for every five degree Celsius increase in temperature. Lower barometric air pressure within the two or three days leading up to a person’s hospital visit also increased the risk of non-migraine headach
