Alcohol's effects

What is alcohol? Alcohol is a sedative hypnotic drug that depresses the central nervous system, making you feel more relaxed. Most adults in the UK drink alcohol moderately and on a social basis and derive a lot of pleasure from doing so. However, about one in five men and one in seven women regularly drink more than the Department of Health suggests is strictly safe for good health. This is up to two to three units of alcohol a day for women and up to three to four units of alcohol a day for men, to a maximum of 14 units a week for women and 21 units a week for men. A unit of alcohol is equivalent to half a pint of ordinary strength beer, a small glass of wine or a single pub measure of spirits. Top Short-term effects of alcohol The short-term effects of alcohol are dependent on the amount consumed and can vary enormously from person to person and from one situation to another. The main effect is on the brain, which can result in: * Slurred speech * Loss of coordination * Unsteadiness when standing or walking * Impaired attention and judgement * Loss of inhibition * Sleep Relatively low doses of alcohol relax the user, make them more talkative and animated. Larger doses lead to uncoordinated movement, impaired decision-making and sedation. The depressive effects of alcohol on normal brain function - especially those causing impaired judgement - are the main reasons it's always best to avoid alcohol when driving and never to exceed the limit. Top Long-term effects of alcohol The cumulative effects of excessive alcohol consumption, especially when associated with a poor diet, affect every part of the body. The two main sites of damage are the liver and the nervous system. The liver may become progressively damaged through a condition known as cirrhosis, which may lead to liver failure, liver cancer and death. The nervous system may be damaged at many levels. Damage to the brain can interfere with intellectual function, and increase the risk of anxiety and depression, confusion and dementia. Damage to the peripheral nervous system can lead to loss of balance, impotence, numbness of the feet and hands, tremor and blindness. Alcoholism is also implicated in diabetes, inflammation of the pancreas, internal bleeding, weakening of the heart, high blood pressure and stroke.
