What will make a drunk person sober again?

The process of sobering up after consuming alcohol primarily relies on time. Alcohol is processed by the liver at a constant rate, regardless of external factors such as hydration, food intake, or physical activity. Thus, the body requires time to metabolize and eliminate alcohol from the system.

While drinking water can help alleviate some symptoms of dehydration caused by alcohol consumption, it does not speed up the rate at which the body metabolizes alcohol. Similarly, while eating food might slow the absorption of alcohol into the bloodstream, it does not remove alcohol already in the system. Exercise, although beneficial for overall health, does not enhance the body’s ability to process alcohol, as it remains dependent on the liver’s metabolic capabilities.

Therefore, the only reliable method for achieving sobriety is simply waiting for the body to naturally eliminate the alcohol over time.
