What Causes Headaches?
Asking what causes headaches is a little bit like asking how long a piece of string is. Although we talk about a headache there are in fact many different types of headache including cluster, migraine, ocular, sinus and tension (or more accurately tension-type) headaches and each of these can have a variety of different causes. In other words there are literally hundred of things that can result in a headache. This said, the vast majority of headaches are simple tension headaches and these are generally caused by such simple things as eye strain from staring at your computer screen for too long or environmental factors such as eating cheese or drinking too much red wine or caffeine.
