Many causes . . .: Check out http://www.mayoclinic.org/symptoms/headache/basics/causes/sym-20050800 for different causes of headaches. Stress & tension is often said to cause headache. Sinus congestion & infection can too. Avoid dehydration in general & specifically hangovers. Don't become dependent upon caffeine which can lead to caffeine withdrawal headaches when you don't get enough.
