The Effects of Alcohol

The effects of alcohol can vary person to person. Alcohol is converted in the body into acetaldehyde. This substance is responsible for, among others, hangovers. These chemical conversions take place in the liver. Also, the following changes take place when drinking alcohol (Alcohol level in per mille, 1/1000):






About 1 glass

About 2 glasses

The blood vessels under the skin dilate, causing a warm feeling. Taste, smell and vision are reduced a little, and also the sense of pain is reduced.


About 1 to 5 glasses

About 2-7 glasses

There is a change of mood and behavior. There is overestimation. A numbing effect starts to play a role. Memory decreases, judging situations become more difficult, and speed of reaction is reduced. Muscle coordination is affected, vision changes.


About 5-9 glasses

About 7-14 glasses

All the above-mentioned effects are enhanced. Behavior becomes excessively emotional. Self-criticism disappear. The face becomes red and gets swollen, pupils dilate. The chance of nausea and vomiting is high.
