Migraine Brain Freeze Hangover Headache Tension Headaches Migraines may be caused by hormonal changes in women, foods such as alcohol, aged cheeses,and chocolate, stress, sensory stimuli such as bright lights, unusual smells, or unpleasant odors, changes in sleep-wake pattern, physical factors, changes in the environment, and medications. Hangover headaches are caused by dilated blood vessels in the brain, loweredblood glucose, and substances in the alcohol that dilate the blood vessels. When something cold touches the roof of your mouth, the sudden temperature change of the tissuestimulates nerves to cause rapid dilation and swelling of blood vessels. The dilation of the bloodvessels triggers pain receptors, and increase sensitivity to further pain.
