Hangover prevention: Does drinking lighter colored drinks help?


By Mayo Clinic News Network


Drinking lighter colored drinks isn't a good method of hangover prevention — but it may help a little. A hangover is caused by several things, including chemicals in alcoholic drinks other than alcohol. Among the compounds linked to a hangover are products of alcohol fermentation called congeners.


Congeners are found in larger amounts in dark liquors, such as brandy, whiskey, darker beer and red wine, than they are in clear liquors, such as vodka, gin and lighter beers. One particular congener — methanol — breaks down into the toxins formaldehyde and formic acid, which can worsen a hangover.


Several studies have investigated hangovers, but none has found an effective method of hangover prevention. While lighter colored drinks may slightly help with hangover prevention, drinking too many alcoholic beverages of any color will still make you feel bad the morning after. Drinking large amounts of alcohol can cause dehydration, low blood sugar, digestive irritation and disturbed sleep — all factors that lead to hangover symptoms.


The only sure way to prevent a hangover is to drink in moderation or not drink at all. For healthy adults, moderate drinking means up to one drink a day for women of all ages and men older than 65, and up to two drinks a day for men 65 or younger. A drink is defined as:

  • 12 ounces (355 milliliters) of beer — about 5 percent alcohol
  • 8 ounces (237 milliliters) of malt liquor — about 7 percent alcohol
  • 5 ounces (148 milliliters) of wine — about 12 percent alcohol
  • 1.5 ounces (44 milliliters) of 80-proof distilled spirits — about 40 percent alcohol

Be careful, though — some drinks may contain more alcohol than you realize. Often drinks are larger at bars and restaurants. And some drinks of the same size may contain more alcohol than others. For example, some light beers contain almost as much alcohol as regular beers, and some liquors contain a higher percentage of alcohol than others.
