Headaches affect 16% of the world's population on a daily basis, and alcohol consumption is one of the main causes.
Although excessive consumption of any alcohol can cause headaches, red wine is the biggest culprit: The headaches it causes come on more quickly than those caused by white wine, beer or spirits. Another important difference is that red wine headaches can be caused by only a glass or two, while other drinks only cause problems once a large amount has been ingested.
