Which method is effective for reducing Blood Alcohol Concentration (BAC)?

Waiting for time to pass is the most effective method for reducing Blood Alcohol Concentration (BAC). Alcohol is metabolized by the liver at a relatively constant rate, usually about 0.015 grams per deciliter per hour for an average adult. This means that the primary way to lower BAC is to give the body time to process the alcohol already consumed.

Other methods, such as drinking coffee, taking a cold shower, or going for a brisk walk, may lead to a false sense of sobriety but do not actually speed up the metabolism of alcohol. These activities can make a person feel more alert or awake but will not decrease the amount of alcohol in the bloodstream. Ultimately, the only reliable way to lower BAC is through time, allowing the body to naturally eliminate the alcohol.
