Question: Does Coffee Sober Up a Drunk?

Does coffee sober up a drunk? You may have heard you can drink coffee or take a cold shower to sober up from drinking alcohol, but does it really help? Here's the answer.

Answer: The answer to this question is a qualified "no". Your body takes a certain amount of time to metabolize alcohol. The time required is dependent on the quantity of alcohol dehydrogenase, an enzyme, that is present. You cannot make this enzyme more abundant or more effective by drinking coffee.

However, coffee contains caffeine, which acts as a stimulant while alcohol is a central nervous system depressant. Although you will be intoxicated until your body metabolizes the alcohol the caffeine can serve to wake you up.
