Headaches almost always occur when you have a hangover. In fact, even drinking small amounts can cause them. Alcohol causes dehydration and stresses your liver. Your liver produces glucose, or sugar, and brain cells are particularly susceptible to shortages in this. Alcohol also has an inflammatory effect, which makes your blood vessels swell.

Drinking plenty of water and eating something bland with protein and carbs, say eggs and toast, will help to get rid of a hangover headache. We recommend making our banana milkshake hangover cure.

Against popular belief, coffee is not a cure for a hangover headache. It can actually make your headache and hangover worse. It is a diuretic, which can cause you to become even more dehydrated.
