According to Dr. Nguyen Huy Hoang, Vietnam - Russia Tropical Center, Ministry of National Defense , based on the common reality of people drinking alcohol in most countries in the world, the World Health Organization (WHO) has introduced the concept of alcohol unit.
One unit of alcohol is equivalent to 10g of pure ethanol, equal to 200ml of beer; 75ml of wine (1 glass); 25ml of spirits (1 cup). Depending on the amount of alcohol consumed, it will be converted to approximately how many units of alcohol.
Drinking a glass of strong alcohol, how long does it take for the alcohol concentration to reach 0 is a question of interest to many people. (Illustration photo)
A healthy adult can eliminate 1 unit of alcohol every hour. This is an average number. Depending on the individual, such as people with weak livers or people who are heavier than average, this time period can increase or decrease.
In addition, pathological factors, age, weight, or when the stomach contains a lot of food, the rate of alcohol absorption in the stomach will be slow and the rate of alcohol excretion will also be slow.
Regarding the body's alcohol excretion mechanism, about 10 - 15% will be excreted through the respiratory tract, skin, and sweat. About 85 - 90% will be processed through the liver.
Drinking 1 glass of strong alcohol (about 40 degrees) is equivalent to 1 unit of alcohol, the liver will take about 1 hour to eliminate. However, after elimination, the body needs 2-3 hours for the alcohol in the blood to return to 0. Therefore, if you drink 1 glass of strong alcohol, it will take you about 3 hours after drinking for the alcohol concentration to not increase.
“There is no exact answer to the question, ‘If I drink a certain amount of alcohol, how long will it take for my alcohol concentration to be zero?’” said Dr. Hoang.
The exact time it takes to completely eliminate alcohol from the body will vary from person to person. We can estimate the time, but this is an average, estimated number. Each individual will have a different time and many factors affect the speed at which the body eliminates alcohol.
