Causes Headaches

headache is pain anywhere in the region of the head or neck, Headaches can often be more than a pain, making it hard to concentrate on anything but the pounding, throbbing, or dull ache inside your head. What causes of headaches? I think changes in sleep or lack of sleep, skipped meals, stress, high blood pressure, and continuous thinking. I read an article in medical journals says that water is an effective treatment for headaches, and drink water continuously relieves headaches, i dont know why? But i agree with this article, In the end, there is no magic cure for headaches, but recent research allows doctor to control most of them.
