Weather “really can cause headache”

A change in the weather really can give you a headache, according to research at the Beth Israel Deaconess Medical Center in Boston.

Doctors have reported that higher temperatures and lower barometric air pressure lead to an increased short-term risk.

Dr Kenneth Mukamal writes in the journal Neurology: "Certainly, our results are consistent with the idea that severe headaches can be triggered by external factors.

"These findings tell us that the environment around us does affect our health and, in terms of headaches, may be impacting many, many people on a daily basis."

A study of 7,000 people who attended a Boston accident and emergency department found that the risk of headache went up by 7.5% for every 5C rise in temperature.

Of these, 2,250 were diagnosed with migraine and 4,803 with "tension" or "unspecified" headaches.

Dr Mukamal reports no association between pollution and headaches, although other research has shown that pollutants in the air can exacerbate problems such as heart disease and stroke.
