The alcohol in alcoholic drinks - such as wines, beers and spirits - is called ethanol. It is a depressant. This means that it slows down signals in the nerves and brain. There are legal limits to the level of alcohol that drivers and pilots can have in the body. This is because alcohol impairs the ability of people to control their vehicles properly.
Short term effects of alcohol include: Sleepiness, impaired judgment, loss of balance and muscle control, blurred speech and vision, increased chance of violence and the occurrence of vasodilation (blood vessels in the skin carry more blood - leading to heat loss).
Long term effects of alcohol include: Damage to the liver and brain. Moderate drinking can lead to a loss of brain cells which can cause impairment of abilities like memory and problem solving. The liver removes alcohol from the bloodstream, as it is a toxic chemical. Over time, alcohol consumption can lead to liver damage - cirrhosis.
