WARNING! DO NOT DRIVE THE CAR IF YOU HAVE been drinking! The negative effects of alcohol on driving are well known. It acts on various brain functions (perception, attention, processing, evaluation, etc..), With different effects and closely related to the amount of alcohol in the blood, that of BAC.
The BAC is measured in grams of alcohol per liter of blood, a blood alcohol concentration of 1g/litro thus indicates that in each liter of blood of the subject is 1 gram of pure alcohol, the BAC can also be expressed in the form 1o/oo (one per thousand) or 0.1%.
The first effects are already beginning to be seen with values \u200b\u200bof 0.2 g / liter, eg the ability to divide attention between two or more sources of information and interaction with fatigue, with a rate of 0.5 g / liter are beginning to be affected the lateral field of vision, reaction time, glare resistance, psychomotor coordination. With a rate of 0.8 g / liter above symptoms get worse and is also compromised the ability to assess distances, attention drops dramatically, decreasing the sensitivity to red light. At a rate of 1 to 1.2 g / liter above symptoms appear and worsen the euphoria, side vision is severely damaged, as well as the perception of distance and speed of movement of objects. A rate between, 5 and 2 g / liter in all the above symptoms are exaggerated, with the complete underestimation of the dangers, the uncoordinated movements (such as accelerating instead of braking), very slow reactions. All this is reflected in the risk of a serious accident.
But how do you reach these values? In other words, how much you can drink before you reach the above values \u200b\u200band the first to feel the negative effects?
The answer is not simple, because everything depends on the diffusion mechanism of alcohol (from the stomach to the blood and then to the liquid cell of the brain), the alcohol content of drinks, from the way in which alcohol is drunk, sex and age of the subject, from his habit of drinking alcohol.
