The alcohol hangover develops when blood alcohol concentration (BAC) returns to zero and is characterized by a feeling of general misery that may last more than 24 h. It comprises a variety of symptoms including drowsiness, concentration problems, dry mouth, dizziness, gastro-intestinal complaints, sweating, nausea, hyper-excitability, and anxiety. The alcohol hangover is an intriguing issue since it is unknown why these symptoms are present after alcohol and its metabolites are eliminated from the body.
Although numerous scientific papers cover the acute effects of alcohol consumption, researchers largely neglected the issue of alcohol hangover. This lack of scientific interest is remarkable, since almost everybody is familiar with the unpleasant hangover effects that may arise the day after an evening of excessive drinking, and with the ways these symptoms may affect performance of planned activities.
Many people favour the (unproven) popular belief that dehydration is the main cause of alcohol hangover symptoms.
