How These Alcohol Compounds Have an effect on Your Hangovers


The pursuit of avoiding a hangover is as previous as alcohol itself. Historical Romans swore by fried canary and sheep’s lungs, whereas the Irish suggested burying your self in moist sand as much as your neck. However one perpetrator that entails no added value or threat of bathroom lung tends to resurface across the holidays: congeners in alcohol.

What are they? Does consuming drinks low in congeners really work? Or is that this an previous (and certain hungover) wives’ story? Let’s check out what the science says.

What Are Congeners?

When grapes or grain are fermented, they produce alcohol — together with byproducts referred to as congeners. These embrace chemical compounds like methanol, acetone, and tannins, which contribute to the colour, scent, and style of an alcoholic beverage, says Gillian Teitz, MS, a biochemist and host of the dependancy science podcast Sober Powered.

What Alcohols Have The Most Congeners?

Mild-colored alcohols include fewer congeners. Examples embrace:

  • Vodka
  • Gin
  • Rum
  • White wine
  • Mild beers

Darkish-colored alcohols include extra congeners. These embrace:

  • Bourbon
  • Whiskey
  • Crimson wine
  • Darkish beers

What Causes Hangovers?

Right here’s a reality worthy of a spit take: Scientists nonetheless don’t totally perceive what causes a hangover. It appears a bit loopy when you think about the familiarity of hangover signs — nausea, headache, fatigue, nervousness, shakiness, and occasional prayers for loss of life.

An early concept — dehydration — is now thought of a separate symptom of an evening of extreme ingesting. Though alcohol is a diuretic (substances that enhance urine manufacturing), some research discovered that individuals who skilled hangover signs weren’t dehydrated.

The present prevailing rationalization entails alcohol metabolism. After we eat alcohol (a.ok.a. ethanol), the physique’s first precedence turns into breaking it down and eliminating it from the physique. Initially, the liver turns ethanol right into a substance known as acetaldehyde, which is believed to be 10 to 30 occasions extra poisonous than alcohol. Acetaldehyde is then damaged down into innocent acetate and water, which is eradicated via urine.

How Do Congeners Have an effect on Hangovers?

The idea continues: The longer alcohol and acetaldehyde stay within the physique, the extra harm they will do, and the more severe your hangover can be. Congeners are believed to compete with ethanol for the physique’s processing bandwidth, and this may end up in alcohol hanging round longer whereas congeners are damaged down, says Teitz.

Some research have discovered that high-congener drinks may cause worse hangovers than low-congener drinks.

“It may be concluded that alcoholic drinks that include extra congeners produce extra extreme alcohol hangovers,” wrote authors of a overview of research within the journal Alcohol and Alcoholism. “Furthermore, a current survey confirmed it takes fewer high-congener drinks to get a hangover, whereas on the identical time the severity of those hangovers is most pronounced.”

It’s all concerning the alcohol

So, to keep away from a hangover, simply keep on with low-congener drinks? Good luck discovering a physician or scientist who will suggest it. Specialists are fairly unanimous: The most important contributor to a hangover isn’t congeners. It’s alcohol itself.

“For those who drink sufficient alcohol, you’ll get a hangover,” says Teitz. “Whereas the quantity of congeners current could barely worsen a hangover, a hangover is brought on by the amount of alcohol you may have consumed.”

“The few experimental research point out that the very best congener beverage (bourbon) ends in extra extreme hangover scores than does the beverage with primarily no congeners (vodka),” wrote authors of a overview of analysis revealed in Present Drug Abuse Evaluations. “Though, ethanol results per se had a significantly stronger impact on hangover than did congener content material.”

In any case, it’s primarily alcohol, not congeners, that causes probably the most bothersome bodily results we affiliate with hangovers: It could actually irritate your abdomen (resulting in nausea or different GI upset), can impression blood sugar stability (making you’re feeling weak or shaky), and might contribute to bodywide irritation and sleep disruption (which may make you’re feeling fatigued, achy, or simply typically awful).

How Do You Keep away from A Hangover?

Nearly everybody who’s tied on one too many has a suggestion on how one can keep away from a hangover after overindulging. These can vary from primary (simply drink water!) to pretty elaborate. For instance, Prime Chef host Padma Lakshmi swears by a pre-bedtime ritual of 1,000 mg of Vitamin C, one liter of water, and an egg-and-cheese sandwich.

However, based on medical science, the official reply is that this: There’s no trickery that may rescue you. “In a number of research, no efficient methodology of hangover prevention was discovered,” mentioned Daniel Ok. Corridor-Flavin, MD, an dependancy psychiatrist on the Mayo Clinic. “The one positive solution to stop a hangover is to drink carefully or not drink in any respect.”

How the specialists outline moderation: Not more than two alcoholic drinks a day for males and no multiple for ladies.

In accordance with the Cleveland Clinic, one drink is equal to:

  • 12 ounces of normal or gentle beer; roughly one can (5% alcohol)
  • 8 to 9 ounces of malt liquor or many varieties of craft beers; about half a pint glass (7% alcohol).
  • 5 ounces of desk wine; about one glass (12% alcohol).
  • 1.5 ounces of liquor; roughly one shot (40% alcohol).

“The very best factor you are able to do to keep away from a hangover is to drink much less alcohol,” says Teitz, “or weigh the professionals and cons and determine that the hangover is value it.”
