Hangovers typically last anywhere from a few hours up to about 24 hours after the last alcoholic drink. However, the duration can vary depending on factors such as the amount and type of alcohol consumed, individual tolerance, hydration levels, sleep quality, age, underlying health conditions, and medications. In some cases, hangover symptoms can last longer than 24 hours, especially if dehydration or other factors are severe. The worst symptoms often peak when blood alcohol concentration returns to zero. The primary way to recover from a hangover is time, with hydration, rest, and nourishment helping to ease symptoms. There are no quick cures, and the best prevention is to drink in moderation or abstain from alcohol altogether.
