How many hours does it take to recover from a hangover?

The recovery time from a hangover can vary widely depending on factors such as the amount and type of alcohol consumed, individual tolerance, hydration, and overall health. Generally, symptoms can last anywhere from a few hours to 24 hours. Most people start to feel better within 12 to 24 hours after their last drink. Staying hydrated, eating well, and resting can help speed up the recovery process.
