Hangovers are worsened by dehydration, disrupted sleep, and electrolyte imbalances caused by alcohol consumption.

Hangovers are caused by disrupted sleep architecture and the negative effects of alcohol on the gut microbiome, leading to headaches and malaise.

Alcohol consumption can impair motor function and judgment, especially in those not accustomed to drinking, and it suppresses the neural networks involved in memory formation and storage, which is why people often forget events from a night of drinking.
