Can alcohol still be detected as drunk driving if it was left overnight? How long does it take for alcohol to be metabolized?

Don't drink and drive, and don't drive after drinking. How long should you rest after drinking to avoid being caught driving under the influence? Do you really know?

On the way back during the Spring Festival travel rush, many people were caught driving under the influence because they had drunk alcohol "every other meal" or "overnight". Not only were they fined, given points, and had their licenses revoked, but their normal return journey was also delayed.

Therefore, the traffic police remind you: If you have drunk a lot of alcohol the night before, it is recommended to wait 24 hours before driving.

How long does it take to metabolize alcohol?

Generally speaking, our body metabolizes about 15-20 mL of alcohol per hour. That is:

If you drink a bottle of low-alcohol beer, it will take about 2 hours to metabolize;

If you drink a bottle of wine with an alcohol content of about 12%, it will take 5-6 hours to metabolize;

If you drink high-proof liquor, it will take more than 21 hours to metabolize it.

Generally, the alcohol content in the body will be greatly reduced 8-12 hours after drinking, and will completely evaporate within 24-48 hours.

Factors that affect alcohol metabolism

The metabolism time of alcohol in the human body is not only affected by factors such as age and gender, but also related to the following factors.

1. Alcohol consumption

If the amount of alcohol consumed is small, the liver has a strong ability to detoxify alcohol, and the alcohol may be completely metabolized within a few hours. However, if the amount of alcohol consumed is large and the liver's metabolic capacity is poor, it may take half a day or even a day to metabolize it.

2. Liver function

After drinking, the alcohol decomposition enzymes that break down alcohol are mainly synthesized in the liver. If the liver function is good and the liver synthesizes more alcohol decomposition enzymes, the alcohol metabolism rate will be faster and can be metabolized within a few hours.

If the liver function is not good and the ability to synthesize alcohol-degrading enzymes is low, it will affect the speed of alcohol detoxification and it may take several days to metabolize it.

3. Sugar/Sugary Fruits

Sugar and sugary fruits can also affect the metabolism of alcohol. Sugar can combine with ethanol to form sugar esters, which can accelerate the metabolism of alcohol.

03

How to promote alcohol metabolism?

After drinking, you can promote alcohol metabolism by the following methods

Drink some honey water appropriately;

Drink more warm water;

Eat hangover-relief foods, such as watermelon, bananas, tomatoes, etc.;

Exercise more;

Take some drugs that promote alcohol metabolism under the guidance of a doctor.

Drinking is harmful to your health. It is recommended to drink in moderation in daily life so as not to cause trouble to your body or your life.
