Step-by-step explanation:
Alcohol has several short-term effects on the body. At low doses, it can cause feelings of euphoria and relaxation. As the dose increases, it can lead to sedation, decreased reaction time, and lowered levels of alertness. Excessive alcohol use can result in a loss of consciousness and difficulty remembering events during intoxication. Furthermore, high doses of alcohol can have negative consequences such as lack of coordination, blurred vision, impaired judgement, and aggression. It can also lead to memory loss, physiological disorders like liver cirrhosis, and an increased risk of certain types of cancer.
