Abstract：
The alcohol hangover is a combination of negative mental and physical symptoms which can be experienced after a single episode of alcohol consumption, starting when blood alcohol concentration (BAC) approaches zero. A popular theory suggests that dehydration is the primary cause of alcohol hangover and that the consumption of water could alleviate hangover symptoms. Here, the current evidence on the relationship between hangover severity, thirst, and water consumption is summarized. The positive correlations of the amount of water consumed with both hangover severity and thirst suggest that both dehydration and the hangover are co-occurring after-effects of alcohol consumption. While hangovers were typically relatively enduring, dehydration effects were usually mild and short-lasting. Survey data revealed that water consumption during or directly after alcohol consumption had only a modest effect in preventing next-day hangover. Also, the amount of water consumed during hangover was not related to changes of hangover severity and thirst. Thus, water consumption was not effective to alleviate the alcohol hangover. Taken together, these data suggests that alcohol hangover and dehydration are two co-occurring but independent consequences of alcohol consumption.
摘要：
酒精宿醉是负面的精神和身体症状的组合，可以在单次饮酒后经历，开始时，血液酒精浓度（BAC）接近零。一个流行的理论表明，脱水是酒精宿醉的主要原因，喝水可以缓解宿醉症状。这里,目前关于宿醉严重程度之间关系的证据，口渴,并总结了用水量。饮水量与宿醉严重程度和口渴之间的正相关关系表明，脱水和宿醉都是饮酒后共同发生的。虽然宿醉通常相对持久，脱水效果通常是温和和短暂的。调查数据显示，饮酒期间或饮酒后直接用水对预防第二天宿醉只有适度的影响。此外，宿醉期间消耗的水量与宿醉严重程度和口渴程度的变化无关。因此，水消耗并不能有效缓解酒精宿醉。一起来看,这些数据表明，酒精宿醉和脱水是两种同时发生但独立的饮酒后果。
