What actually lowers a person's blood alcohol concentration after drinking?
Correct answer: Time for the body to process alcohol.
Why
The body needs time to metabolize alcohol. Coffee, a cold shower or fresh air cannot quickly restore driving judgment or coordination. Do not estimate a safe drive time from how awake you feel; arrange a sober ride.
