How Can I Sober Up Fast? What Works and What Doesn’t

Many people want to know how to sober up quickly. A search of the internet yields many suggestions. But which of them are just myths? Or worse, dangerous?

Google: Sober Up Fast?

Suggestions on the internet to how to sober up fast include drinking strong black coffee. Widely recommended is taking a cold shower. Many sites suggest drinking lots of water. Many also favor doing anything to sweat. This is to sweat the alcohol out from the bloodstream.

Here are some other recommendations you might find on the web.

Which work and which are just myths?  Let’s examine these recommendations more closely.

Drink coffee.

Coffee, tea and many other beverages contain caffeine. But caffeine doesn’t help our bodies metabolize or break down alcohol. It does make us feel alert.

But we’re just as intoxicated and impaired. And feeling alert may fool us into thinking we are safe to drive. So drinking coffee is not simply ineffective. It can have dangerous consequences.sober up

Take a cold shower.

This does nothing to lower our blood alcohol concentration (BAC). It can briefly make us more alert but we’re just as impaired. However, it might cause some people to go into shock or have a heart attack. Or they could have other serious medical problems.

One site even suggests alternating cold with hot showers. Doing this would greatly increase the medical risks.

Drink lots of water.

Alcohol dehydrates us. Drinking water should reduce the effects of hangover. Unfortunately, it’s useless for sobering up.

Get lots of fresh air.

Fresh air can make us feel better. But it has no impact on our BAC.

Vomit.

Vomiting has no impact on the level of alcohol that is already in our bloodstream.

Sweat.

Sweating, either from exercise or a sauna, has no impact on our rate of sobering.

Eat.

Eating while drinking can reduce the absorption of alcohol into the blood. But once alcohol is in the bloodstream, eating has no effect on it.

Have your face slapped.

Being slapped is not only painful but ineffective. It can make us briefly more alert. Of course, we remain just as drunk.

Take a multi-vitamin.

Taking multivitamins has no impact on our BAC.

Take a metabolism pill.

Taking a commercially produced pill to speed up metabolism might seem reasonable. However, these products escape testing by the Food and Drug Administration (FDA).

The sellers of these unregulated products make unsupported claims of their effectiveness. There is absolutely no evidence that they can help us sober up. Save your money.

So they’re all myths.

And all the other suggestions on the internet for sobering up faster are also myths. Smoking tobacco, massaging your hands and feet, none of it is going to work.

Time is the only thing that will sober up a person.

And we can’t speed up time.

The amount of time needed to reduce our BAC is easy to calculate. And it’s the same for virtually everyone. Height, weight, sex, race or other such factors don’t matter.

BAC drops at the rate of .015 of BAC every hour.  So a person with a very high BAC of .15 will have no measurable alcohol in the blood after ten hours.  That’s because .15 divided by .015 = 10. Here are some other examples.

BAC Level Metabolism Time in Hours
.10 6.66
.08 5.33
.05 3.33
.02 1.33

It’s important to know that BAC can continue to rise for a period of time after the last drink.

Be very cautious about advice on the internet.

This is especially important with health matters. Pages about how to sober up are full of false and misleading assertions. Some suggestions are actually dangerous. When in doubt, simply ask your doctor.

However, there are safe ways to either prevent or reduce hangovers.
