Many people believe that drinking coffee after a night of heavy drinking can help to sober you up.
But is there any truth to this belief, or is it just a myth? In this article, we will explore the science behind the effects of coffee on alcohol intoxication and answer the question of whether coffee can really sober you up after a night of drinking.
How does alcohol affect the body?
Before we can understand the potential effects of coffee on alcohol intoxication, it’s important to understand how alcohol affects the body in the first place. Alcohol is a depressant drug that slows down the central nervous system.
It acts on the brain, altering mood, behavior, and coordination.
When you drink alcohol, it is absorbed into the bloodstream and distributed throughout the body. The liver is responsible for metabolizing alcohol and breaking it down into harmless substances that can be excreted from the body.
However, the liver can only process a certain amount of alcohol at a time, and when you drink more alcohol than your liver can handle, the excess alcohol builds up in the bloodstream, leading to the symptoms of intoxication.
The symptoms of alcohol intoxication vary depending on the amount of alcohol consumed, but can include slurred speech, impaired judgment, slowed reaction time, loss of balance, and blackouts.
In extreme cases, alcohol poisoning can occur, which can lead to coma or even death.
How does coffee affect the body?
Coffee is a stimulant that affects the nervous system by blocking the action of adenosine, a neurotransmitter that promotes sleep and suppresses arousal.
By blocking adenosine, coffee increases the levels of other neurotransmitters like dopamine and norepinephrine, which can help to improve mood, alertness, and cognitive function.
Caffeine, the active ingredient in coffee, is rapidly absorbed into the bloodstream and reaches its peak concentration in the blood within 30-60 minutes of consumption.
The effects of caffeine typically last for several hours, but can vary depending on factors like the amount of caffeine consumed, individual tolerance, and other factors like age and weight.

Can coffee sober you up after drinking?
So, can drinking coffee after a night of heavy drinking actually sober you up? The short answer is no, coffee cannot sober you up after drinking.
While coffee may help to improve alertness and cognitive function, it does not have any direct effect on the metabolism of alcohol in the body.
The only way to lower your blood alcohol concentration (BAC) and sober up after drinking is to wait for time to pass and for your body to metabolize the alcohol naturally.
Drinking coffee after drinking alcohol may lead to a false sense of sobriety, as the caffeine may mask some of the symptoms of intoxication like fatigue and drowsiness.
However, this does not mean that your BAC has decreased or that you are no longer impaired.
Can coffee make you more intoxicated?
There is some evidence to suggest that drinking coffee after alcohol consumption may actually increase the level of alcohol impairment.
A study conducted by researchers at the University of Barcelona found that drinking coffee after drinking alcohol could lead to a higher BAC and more severe impairment compared to drinking alcohol alone.
It is thought that this effect may be due to the fact that caffeine can increase the rate of gastric emptying, which can cause alcohol to be absorbed more quickly into the bloodstream.
This can lead to a higher BAC and more severe impairment compared to drinking alcohol alone.
What are some alternatives to sobering up?
If you have been drinking and need to sober up, there are a few things you can do to help your body metabolize the alcohol more quickly:.
- Drink water to help prevent dehydration
- Eat a meal or snack to help slow the absorption of alcohol
- Take a nap to help your body recover
- Avoid driving or operating heavy machinery until you are completely sober
- Seek medical attention if you or someone else is experiencing alcohol poisoning
Conclusion
While many people believe that drinking coffee after a night of heavy drinking can help to sober you up, there is no evidence to support this claim.
In fact, drinking coffee after alcohol consumption may actually increase the level of alcohol impairment and lead to a higher risk of harm. The only way to truly sober up after drinking is to wait for time to pass and for your body to metabolize the alcohol naturally. If you have been drinking, it is important to take steps to stay safe and prevent harm.
