Impact of alcohol on aging

The impact of alcohol on aging is multifaceted. Evidence shows that alcohol consumption can cause both accelerated aging – in which symptoms of aging appear earlier than normal – and exaggerated aging, in which the symptoms appear at the appropriate time but in a more exaggerated form.http://pubs.niaaa.nih.gov/publications/arh23-4/272-283.pdf]

Alcohol is a potent neurotoxin. [cite book|author=Thomas P. Beresford, Edith Lisansky Gomberg, Edith S. Gomberg|title=Alcohol and Aging|pages=85] The National Institute on Alcohol Abuse and Alcoholism has found, "Alcoholism may accelerate normal aging or cause premature aging of the brain." [ [http://pubs.niaaa.nih.gov/publications/aa40.htm Alcohol and Aging - Alcohol Alert No. 40-1998 ] ] Another report by the same agency found, "Chronic alcohol consumption, as well as chronic glucocorticoid exposure, can result in premature and/or exaggerated aging." Specifically, alcohol activates the HPA axis, causing glucocorticoid secretion and thus elevating levels of stress hormones in the body. Chronic exposure to these hormones results in an acceleration of the aging process, which is associated with "gradual, but often dramatic, changes over time in almost every physiological system in the human body. Combined, these changes result in decreased efficiency and resiliency of physiological function." Chronic stress and chronic heavy alcohol use cause a similar premature aging effect, including nerve cell degeneration in the hippocampus. Non-alcoholics tend to be faster and quicker in cognitive abilities than alcoholics of the same age. [ [http://serendip.brynmawr.edu/bb/neuro/neuro00/web1/Kim.html Alcohol and its effects ] ]

Drinking too much can also interrupt one's sleep, causing a tired look.
