What Causes
Barometric Pressure Headaches?
Barometric pressure headaches are caused due to air-pressure changes following weather changes. This might sound a very simple definition; but the justification is not as candid.
Many opinions have been expressed about barometric pressure headaches, some of which accept the role of weather while others negate it.
Scientists and researchers have long tried to fathom the relationship between weather changes and headaches.
Their efforts have led to the following findings:
* Change in pressure (effected by seasonal changes) brings about changes in the oxygen level, which in turn causes headache.
* Many a times the blood vessels try to compensate for the lowered oxygen level by contracting and expanding. This exertion leads to migraine.
* Headaches and migraines can be the resultant of many factors (which are often weather-related) – like high temperature and humidity, overcast skies, etc. etc.
* Weather changes sometimes also effect chemical changes in the body, which again trigger headaches and migraines.
* Electrically charged air very often sets off a bad headache.
These findings do not go uncontested and they have been strongly opposed. Scientists opposing the above assertions opine that the fluctuation in pressure resulting from seasonal changes is far too insignificant to lead to serious health crisis.
