Are you getting confused in search of your answers related to bac? Don’t worry; we will clear your confusion and provide the exact answer that will help you in your matter. Many articles tell that a person’s bac will go down if they drink coffee, take a cold shower, or vomit after drinking alcohol. Here, we will discuss whether they are right or wrong and the right answer for it.
Before debating the right answer, here are some facts about what the bac is. Let’s dive into the detail;
What is bac?
BAC is actually used for Blood Alcohol Concentration, and it is the percentage of alcohol (ethyl alcohol or ethanol) in the bloodstream. For example, if the value of bac is 10% in the bloodstream, that means every 1000 parts of blood contains one part of alcohol.
Thus, it is the measurement of alcohol intoxication used for legal or medical purposes. However, the percentage of legal alcohol intoxication is 0.8% established by law enforcement of California. Any person having more than it will be considered to be involved in illegal activity. Moreover, some factors will determine the bac level in a person’s bloodstream;
- Food that they eat
- Medications
- Hormonal level
- No. of standard drinks
- Weight of the body
- The time calculation for alcohol consumption
Now we will discuss the correct answer or whether a person’s bac will go down by drinking coffee, taking a cold shower, or vomiting.
A person’s bac will go down if they drink coffee, take a cold shower, and vomit:

Now it’s the most focused question of how the bac level will go down via any technique or hack. However, none of these will reduce the bac level from a person’s bloodstream. Here are reasons for not letting down its concentration;
- When a person suffers from an illegal bac level, their bloodstream contains alcohol molecules. These molecules cannot be removed via a cold shower as they don’t have internal molecules. A person feels active after a cold shower when they have a higher bac level due to the cooling effect. It has nothing to do with medication.
- In the same way, drinking coffee will only put caffeine in the body, via which you feel active. It doesn’t play any role in reducing the bac level. Caffeine affects the kidneys via which kidneys pull water from the blood and surely the ethanol too. This causes the removal of ethanol, not reducing the bac level.
- Let’s take a look at vomit after drinking alcohol. You might say it eradicates alcohol from the body, but do you think how vomit can eradicate alcohol molecules from the bloodstream? The answer is straight; if a person has alcohol in the stomach, vomit can eradicate it to prevent further consumption. But it will never reduce the bac level because vomit doesn’t have any connection with the bloodstream.
Thus, you are assuming what could be the solution for it. So, a person’s bac will go down if they stop consuming alcohol and wait for a period when the liver does its work to eradicate or degenerate alcohol molecules. Now you have a proper answer for your confusion related to bac. Hoping for you or your friend’s good health
