Study links migraines to weather

This may not come as a big surprise, but a new study finds, some people may be vulnerable to developing severe headaches when the temperature climbs or atmospheric pressure drops. A study in the journal Neurology found the risk of migraine and non-migraine headaches tended to climb along with temperature.

This trend was seen during warm and cold months alike.

Also, the risk of non-migraine headaches increased during the 2 to 3 days following a drop in barometric pressure.

Low barometric pressure generally means cloudy skies and storms while high pressure means clear skies.

No one is sure why this happens, but experts say they do know there are a lot of physiological effects of environment, including changes in blood pressure and nerve function.
