What is the only method to reduce one’s alcohol concentration effectively?

Waiting is the only effective method to reduce one’s alcohol concentration because the body metabolizes alcohol at a consistent rate, typically about one standard drink per hour. This process is governed by liver function, and no external factors can speed it up. Drinking coffee, exercising, or eating food may create the illusion of sobriety or may help an individual feel more alert, but they do not decrease the amount of alcohol in the bloodstream. In fact, while a person may feel more capable after consuming caffeine or exercising, their blood alcohol content remains unchanged until the body has had enough time to metabolize the alcohol naturally. Waiting allows the body to complete this process, making it the only reliable way to reduce alcohol concentration.
