Definition & Meaning of "hangover"

What is a "hangover"?

A hangover is the unpleasant set of symptoms experienced after consuming too much alcohol, typically the morning after heavy drinking. Symptoms of a hangover typically include headache, fatigue, nausea, sensitivity to light and sound, dehydration, muscle aches, and irritability. These symptoms can vary in severity depending on factors such as the amount of alcohol consumed, individual tolerance levels, hydration status, and overall health. Hangovers are caused by a combination of factors, including dehydration, the toxic effects of alcohol metabolism, inflammation, and disruption of sleep patterns. While there is no cure for a hangover, symptoms can be alleviated by staying hydrated, getting rest, eating a balanced meal, and avoiding further alcohol consumption.
