How long does it generally take for 1.0 per mille of alcohol to be broken down in the blood?

After an intense evening, the blood alcohol level can still be detected in the blood hours later. Even with an initial value of 1.0 per mille, it takes an average of 10 hours for the value to rise 0.0 per mille sinks. Since the reduction is linear, the alcohol level only decreases minimally every hour. This means that even after a long night’s sleep, residual alcohol is often still present in the blood. You should be particularly careful here as the risk of accidents or fines on the road remains high.

• 10 hours

Why does it often take 10 hours to break down alcohol?

The human body breaks down alcohol at a constant rate, regardless of the amount consumed. The main work is done by the liver, which is about 90% of alcohol metabolized. Another part is excreted through sweat, breath and urine, but to a lesser extent. Experts estimate that the reduction of 1.0 per mille takes place in about 10 hours because of the speed at which alcohol is broken down 0.1 to 0.15 per mille per hour is limited. However, individual differences play a major role here.

Factors that can prolong the elimination of alcohol up to 10 hours

The length of time it takes to break down alcohol depends on numerous factors. This includes:

1. Body weight and fat percentage – People with more body mass tend to break down alcohol faster.
2. Gender – Women have less body water, which makes dilution with alcohol more difficult.
3. genetics – The efficiency of liver enzymes, especially alcohol dehydrogenase, varies from person to person.
4. Health – A damaged liver, for example due to alcohol abuse or illness, slows down the breakdown process.
5. Type of alcohol consumption – High-proof drinks or mixtures with sugar can affect the absorption and processing of alcohol.
