How much does alcohol in the blood? What is the normal blood alcohol content?

Currently, no holiday is complete without taking alcohol. However, many are interested in the question: "How much alcohol does alcohol hold in the blood?" When, after taking alcohol, you can get behind the wheel or go to work?

What is alcohol?

If you are guided by the terms of chemistry, then alcohol can be called any alcohol - a compound containing several hydroxyl (OH) groups. From a marketing point of view, alcohol is any alcohol-containing liquid.

Alcohol burns well, which is associated with its chemical properties.

Currently, alcohol is widespread. They can be purchased in grocery stores (alcoholic beverages), and in the ranks of industrial products (perfumes, some liquids for cars, etc.).

Due to their properties, some alcoholic beverages and liquids can be consumed inside (except for technical alcohols - methanol, propanol, etc.).All of them are poisons, but ethyl has the lowest toxicity among all alcohols.

It is part of the food alcohol, which we are accustomed to drink for various celebrations and holidays. However, how should this alcohol be consumed without harm to health and surrounding people?

Blood Alcohol Rate

Is there any alcohol in our blood in a normal state? As it turned out - there is. Its concentration is low, and sometimes it can not be detected by any tests. However, with a more thorough study, it was proved that there is still a fraction of a percent of alcohol in our body.

As studies show, in normal blood up to 0.3 ppm of alcohol can be contained, and in exhaled air (determined if it is necessary to “blow into a tube”) to 0.15. The excess of these figures allows to judge about alcohol intoxication.

It is formed as a result of certain metabolic processes and is a by-product of the reaction, but without its formation, the reaction cannot proceed, so you have to put up.

Some everyday factors (for example, hard work) can contribute to an increase in its concentration even in a sober state.It all depends on the fermentation processes in our muscles. As a result of metabolism, lactic acid and a certain amount of alcohol are formed in them, but it does not exceed a tenth of a percent. It contains quite a short time; there may be no alcohol in the blood in half an hour after the work, but it will be in the muscles. Therefore, we can assume that work or sports are “intoxicating”.

Factors affecting the retention of alcohol in the body

"How much does alcohol in the blood hold?" - the question is quite vague. It depends on the strength of the alcohol, the quality of the product, who consumes alcohol, its body mass and mood. As can be seen, there are quite a few factors that influence the retention of alcohol in the blood.

Each of them matters, because all people are different in nature: someone is small and skinny, someone, on the contrary, is big and massive. In these two people, the metabolism (metabolism) will go differently. That is why the answer to the question "How much alcohol is kept in the blood?" pretty ambiguous.alcohol in the blood keeps

Plays a significant role and such factors as the body's sensitivity to alcohol.It is caused by a special enzyme - alcohol dehydrogenase, the level of which is different for each person.

Undoubtedly, the function of the excretory system, as well as what was eaten in parallel with the alcoholic beverage, will also affect the time alcohol is removed from the blood.

It is worthwhile to dwell on each of the factors in more detail.

Fortress of liquor

Surely each of us paid attention to the label of alcoholic beverage. It indicates the composition from which the alcohol was produced, the alcohol content in the volume, as well as the number of revolutions.

The most important is the amount of alcohol - the content of the pure product per 100 grams of solvent (usually water). The more alcohol is contained in an alcoholic beverage, the stronger it is.

Some parallel can be drawn with the human body. Most of our body is liquid, solvent. The more we consume strong alcohol, the higher will be its concentration in this solvent and the longer it will be removed. If a little alcoholic drink, its use can pass completely without a trace, but it will still be determined in the blood.

For example, if you take a person with an average weight of 80 kg, if you use strong alcoholic beverages (40% vodka or 42% cognac) to 100 g, alcohol will be in the blood for about 4.5 hours. If the mass is greater (for example, 100 kg), then the same dose of alcohol will be eliminated from the body more slowly (about 5 hours).

If we take into account only the factor of strength, then it is clear that the alcohol content in the blood will be the higher, the stronger the alcoholic drink and the more it was taken.

Gender as one of the factors affecting alcohol concentration

Almost with absolute certainty, we can say that gender is one of the dominant factors in the development of intoxication.

Women, due to the fact that their body is weaker metabolic than the male, are experiencing alcohol intoxication much faster than men. How long alcohol in a woman’s blood can be is a moot point. Several factors play a role here:

  • First of all, you should pay attention to the level of alcohol dehydrogenase. In women, it is produced much less than in men, so their blood contains alcohol a little longer. The reserves of the enzyme are not infinite, and in women, due to metabolic reactions, it is also recovering more slowly.
  • Ladies prefer sparkling alcoholic beverages (champagne, sparkling wines). This factor contributes to the fact that alcohol is faster, due to the saturation of the drink gases, enters the blood, thereby causing faster intoxication. However, after taking such drinks, women usually get sober faster, as they usually stop using after the first signs of alcohol.
  • Physiologically, a woman’s body weight is much less than that of a man; therefore, strong alcohol causes intoxication an order of magnitude faster than women and stays in their blood a little longer, because in women blood proteins have a tendency to more strongly bind to alcohol than men. of which, their blood alcohol content is much higher with the same volumes drunk.blood alcohol count

For example, a woman weighing about 60 kg consumes liquor. Fortress liquor - 30 percent. 100 g of such liquor from the body of a woman will be removed for about 5 hours, and when consumed, for example, half-liter, alcohol will circulate in blood almost a day.

Body mass

About the weight of a person and the influence of alcohol on him has already been mentioned above. The greater the mass of the human body, the theoretically more fluid in it.It is because of this that it is quite difficult to reach the necessary concentration of alcohol in the blood of such people - it is necessary to take strong alcoholic drinks in sufficiently large quantities. However, such people sober much more slowly than long does alcohol in the blood

It all adds up to the thin. The concentration of fluid in the body is small; incoming alcohol dissolves in a smaller volume of solvent and causes intoxication of the body more quickly. However, there is a small body mass and a plus - blood is less than that of larger people, and the kidneys require less cycles to clear the blood from alcohol. Due to this, in thinner people alcohol in the blood is kept much less than in obese and fat subjects.

Consider this situation. A man weighing 70 kg consumes beer (4%). when consumed half a liter of this drink in the blood, it will be about 2.5 hours. In a fuller man, this volume will be displayed almost completely in 3-4 hours.

Given this factor, we can say that alcohol lasts longer in the blood of large people than in smaller ones.

Emotional attitude

In the people there is a saying: “Drink and you will become more fun.” However, it is deceptive.Alcohol in no way affects the mood. He can either worsen it if it is corrupted or a person is loaded with his own problems, or, conversely, to stimulate if a person is happy. It all depends on whether the subject wants to be fun.

The character of a person is also an important trait. Choleric and sanguine - usually quite active people. By virtue of their nature, positive emotions appear more often than phlegmatic and melancholic emotions. Such people get drunk quickly, but because of their activity, alcohol is eliminated from the body more quickly.

In melancholic and phlegmatic all the way around. Their metabolism is usually somewhat lower than that of other people. That's why alcohol stays in blood much long does alcohol in the blood

Because of a more closed mood, such people are prone to slow intoxication and slow sobering up. Therefore, to drink such people is recommended weak alcoholic beverages, as they will be displayed for a long time.


What a booze without a snack ... Someone prefers a wide and generous table, someone is guided by a smaller one. However, this factor is also important in deciding how much alcohol is contained in the blood.

The leaner the appetizer, the faster intoxication occurs. However, alcohol in a “pure”, unbound form enters the bloodstream, and from there it is easier for it to go out with the help of, for example, kidneys.

If the table was abundant, and the dishes - high-calorie and fat, the situation is somewhat more complicated. First of all, alcohol binds to food molecules, which makes it harder for the enzyme to act on it. Food helps to reduce the concentration of alcohol formed in the blood, however, it increases the residence time of alcohol in the body. A person may not feel intoxicated, but his blood will contain quite a lot. This may create a problem with the traffic police, because, without feeling intoxicated the next day, a person can get behind the wheel, but alcohol has not gone anywhere from the blood, and some of it will still be there. If you breathe into the tube, you can see that alcohol is still present in the blood.
