What alcohol does to the body
Alcohol has a direct effect on the body. It numbs the brain and affects your emotions: it can trigger feelings of elation or audacity, but also aggression, carelessness, rest, sleepiness, relaxation, apathy or indifference.
Consuming large amounts of alcohol slows down your responsiveness and reaction time. You hear and see less sharply. Your self-confidence can increase to a misleadingly high degree and turn into boldness. This can be dangerous, for instance in traffic. As such, alcohol use is a key risk factor for accidents and injuries.
An even greater amount of alcohol lowers your control over your movement and coordination skills. Walking turns to staggering, and talking to lalling. Often, you fail to remember exactly what has happened or what has been discussed. Excessive alcohol consumption can put you in a coma and cause heart problems.
