A hangover is the after-effect following the consumption of large amounts of one drug or another. In particular, it is most commonly associated with the consumption of alcoholic beverages.

Veisalgia is the medical term for the condition.

1 The symptoms

An alcohol hangover is associated with variety of symptoms. Depending on severity, they may include dry mouth, headaches, irritability, bloodshot eye , sensitivity to light and noise, or nausea and vomiting.

2 The cause

Hangovers are multi-causal. Ethyl alcohol has a dehydrating effect, which causes headaches, dry mouth, and lethargy. This can be mitigated by drinking plenty of water between and after the alcoholic consumptions. Alcohol is also a metabolic poison, and its impact on the stomach lining probably accounts for the nausea.

Another factor contributing to hangover is the conversion of alcohol to acetaldehyde by the liver by the enzyme alcohol dehydrogenase. This metabolite is probably more toxic than alcohol.

Finally there are various nervous effects. The removal of the depressive effects of alcohol in the brain probably account for the light and noise sensitivity.

It is also thought that the presence of other alcohols (such as methyl alcohol and fusel oils), by-products of the alcoholic fermentationIn its strictest sense fermentation is the energy-yielding anaerobic metabolic breakdown of a nutrient molecule, such as glucose, without net oxidation. Fermentation yields lactate, acetic acid, ethanol, or some other simple product. Fermentation is also also called congener s, exaggerates many of the symptoms; this probably accounts for the mitigation of the effects when distilled alcohol, particularly vodka, is consumed.

The amount of tannin in the drink may also have an effect. Red wines have more tannins than white wines, and some people note less of a hangover with white wine.

Some people believe that sugarThis article deals with sugar as food and as an important, widely traded commodity; the word also has other uses; see Sugar (disambiguation A sugar is a form of carbohydrate; the most commonly used sugar is a white crystalline solid, sucrose; used to alte (often found in sweet cocktailIn scuba diving, the word "cocktail" is also used to mean a hazard with diving with some rebreathers: it means a caustic solution resulting from water reaching and dissoving the absorbent. high-proof alcohol which is ignited prior to consumption. A cocktas) worsens hangovers.

NicotineNicotine is an organic compound, an alkaloid found naturally throughout the tobacco plant, with a high concentration in the leaves. It constitutes 0. 3 to 5% of the plant by dry weight. The biosynthesis takes place in the roots and it is accumalated in th poisoning can often worsen hangovers, as smokers tend to smoke much more than usual while under the influence of alcohol.

Genetics also plays a part, as some people seldom, if ever, suffer hangover symptoms no matter how much they drink.

The amount of flavor compounds in the drink will increase the hangover, so a dark beer, or stout, such as GuinnessArthur Guinness Son & Co. founded 1756, produces a dark stout (a type of beer, specifically porter), known widely as Guinness brewed at St. James's Gate, Dublin, Ireland since 1759. It is also brewed under licence internationally the resulting beer is, fr will produce a worse hangover than drinking the equivalent amount of alcohol diluted in water (basically Vodka, which, if drunk pure, doesn't usually cause strong hangovers).

The psychosomatic nature of hangovers shouldn't be ignored either. If people expect a hangover, they tend to feel one.

3 The cures

Common folk medicine has a wide variety of hangover cures. Indeed there appear to be nearly as many ways of curing hangovers as there are of getting drunk in the first place. Essentially all of these hangover cures have one major thing in common, which is that they are nowhere near as effective at curing a hangover as alcoholic drinks are at getting you drunk.

Among the more common (and relatively effective) cures are:

A reasonably effective recipe developed by college students at Franklin & Marshall College uses the following.

Directions: consume all the above together and immediately go to sleep.

It is notable however, that the liver can be highly stressed by processing the amount of alcohol necessary to cause a hangover, and taking pain medicine that the liver needs to additionally process, can be toxic or damaging. This is especially true with acetaminophen/paracetamol (Tylenol), which has known liver toxicity implications.

Another cure that the Northern Irish will Swear by is the Ulster Fry, a meal that is an all day breakfast.

All fried in the same frying pan is the traditional version. Additions to the meal are:

or of course all of the above.

As of 2003, the latest fad hangover cure is a Russian pill, sold in Russia as Antipokhmelin (Anti-Hangover), and marketed as RU-21 in the USA. It is also known as the KGB pill due to its supposed use by the KGB to allow spies to keep a clear head while drinking.
