Hangover headache occurs after excessive consumption of alcohol. Headache is one of the symptoms of hangover and it might be associated with other symptoms like nausea, vomiting, diarrhea, excessive thirst, depressed mood, anxiety, irritability, fatigue, weakness, photophobia, etc. The headache is usually described as throbbing headache occurring in the frontal and/or occipital (posterior) region of the head. Usually hangover is experienced in the morning following a night of heavy drinking. However, it can occur anytime after the intoxicating effects of alcohol have subsided.
The mechanism of hangover has not been known, but possible causes like dehydration, congeners, or the ethanol metabolite acetaldehyde are supposed in many theories behind it.
Innumerable methods have been suggested as a remedy for hangover, but only few have proven effectiveness. Even those with proven efficacy may not be effective in all the people.
Some of the methods that provide some relief from the symptoms of hangover are:
The following popular methods of "treating" hangover have no effect in treating or preventing hangover headaches. Moreover, many of these may even worsen the condition. So when you heard about these, just ignore them.
Only definitive preventive measure is not drinking alcohol (or drinking very little alcohol). However, complete abstinence from the alcohol may not be possible. Therefore, the ideal step is to drink only moderate amount of alcohol that won't cause hangover. The hangover symptoms and the severity increases with the increased amount of alcohol intake. However, there is no clear cut limit for the amount of alcohol that will prevent hangover in all people. The amount of alcohol that can be tolerated varies from person to person. Ideally, the currently recommended maximum amount of alcohol is one drink daily for women and two drinks daily for men (one drink having approximately 14g of ethanol).
As already mentioned above, drinking lots of fluids before going to bed also helps in preventing or at least reducing the severity of headaches next morning.
