The drug increases blood flow to the skin, producing a feeling of warmth, while the body is actually losing heat internally. High levels of alcohol use can lead to dangerously slowed breathing, unconsciousness, alcohol poisoning, coma or death. A hangover is the body's reaction to mild alcohol poisoning after a bout of excessive drinking. This often results in dehydration, headaches, stomach pain, and possibly, nausea and vomiting. There is no cure for a hangover, though it can be avoided by moderating alcohol intake.
Alcohol acts on the emotional and cognitive centers of the brain.
It is often mistakenly confused as a stimulant because one of its initial effects includes reduced inhibitions in the user. In low doses, alcohol can produce relaxation and a sense of well-being. As amounts increase, an individual may become confused, forgetful, withdrawn, depressed, angry or talkative, as well as experiencing the loss of decision-making skills. Because of its effects on the brain, alcohol use has been linked to a significant amount of violent crime. In the U.S., one half of all murders and one third of all suicides involve alcohol.
