Why hangovers happen

This is the very worst thing you can do. By putting alcohol back into your body and brain, you are only delaying your hangover! Eggs, in particular, contain a lot of the nutrients your body need. Probiotics are known to reduce leaky gut, and a very small study of heavy drinkers showed the subjects who took probiotics had reduced levels of inflammation in their bodies. Most of these have no evidence, although it might be worth your taking a B vitamin complex.

Some companies are developing combination treatments to speed up alcohol metabolism — they seem promising but expensive.

In theory, any exercise you do will speed up your metabolism and shift your hangover. However, you are unlikely to feel like doing this.

Sensible drinking is about restraint, which might be easier when you know that alcohol impairs you the next day. Excerpted from the new book Drink? David Nutt here:.

Unfortunately, a significant part of this group also has a mutation in the gene for the enzyme that performs the next metabolic step , leading to a much slower conversion of acetaldehyde into acetic acid.

As a result, excess buildup of acetaldehyde can happen quite rapidly. This is known to cause an immediate alcohol flush reaction colloquially known as "Asian glow" , but might also play a role in hangovers the day after drinking. There are other factors that affect who experiences hangovers most readily. After having the same number of drinks, women are more likely to experience hangovers than men , though this simply seems to be a result of the fact that women generally have a lower body weight as well: If you control for body weight and compare a man and woman with the same blood alcohol content, their chances of a hangover are similar.

There's conflicting evidence over whether hangovers become more frequent with age. Some studies have suggested [PDF] that adolescents are less likely to experience hangovers, but a recent large-scale survey showed the opposite—that, even controlling for total alcohol consumption, drinkers over the age of 40 experienced fewer and less severe symptoms.

The authors noted that it's possible, though, that they consume the same amount of alcohol but with less intensity, spreading their drinks out instead of binging. Because the ultimate cause of a hangover is, after all, alcohol, drinks that pack more alcohol into a smaller volume are naturally more likely to give you a hangover.

Shots of liquor, in other words, are more dangerous than mixed drinks, beer or wine. Beyond that, though, some drinks happen to have higher levels of congeners —traces chemicals produced during fermentation—that contribute to hangovers.

Studies have shown that high-congener, darker-colored liquors like bourbon and whiskey lead to more severe hangovers than lighter-colored or clear liquors like vodka, which has none. A Dutch study systematically looked at the congener content and hangover risk of a variety of types of alcohol, producing the ranking above. One particular congener called methanol —found in highest levels in whiskey and red wine—has received a large amount of the blame, due to studies showing that it can linger in the body after all alcohol has been eliminated, perhaps accounting for the enduring effects of a hangover.

This, incidentally, could explain widely-held belief that mixing different sorts of liquor can cause a hangover—a greater variety of congeners could well lead to a wider variety of effects. It can't, however, explain any beliefs about the order of these drinks—despite the age-old adage "liquor-then-beer-you're-in-the-clear, beer-then-liquor-you've-never-been-sicker. The most effective solution is also the most obvious: Don't drink alcohol.

Or, at the very least, don't drink to excess. If you're set on drinking a fair amount, though, there are certain things you can do to minimize your change of a hangover and the severity of its symptoms, and they're all pretty intuitive. Don't drink quickly, on an empty stomach; drink slowly, either on a full stomach or while eating.

Food doesn't literally absorb the alcohol, but having a full digestive tract slows down the rate at which your body absorbs the drug.

Additionally, even though dehydration is only partly to blame, it still plays a role, so staying hydrated while drinking alcohol can help.
