Can the weather cause migraines?
I tend to get awful headaches that fall under the migraine classification but I notice that they're weather related. Why is it that weather should have these effects?
I don't know whether there is evidence for a direct relationship between weather, atmospheric pressure and headaches. But one thing that does occur to me is that, if you have high atmospheric pressure, usually that's associated with warm conditions. When people get very hot, they can get dehydrated. One symptom of dehydration is a fierce headache. That could be one of the reasons for your headache symptoms...
