Debaucherous evening last night? You’re probably dealing with veisalgia right now.
More commonly known as a hangover, this unpleasant phenomenon has been dogging humanity since our ancestors first happened upon fermentation.
Those nasty vertigo-inducing, cold sweat-promoting and vomit-producing sensations after a raucous night out are all part of your body’s attempt to protect itself from injury after you overindulge in alcoholic beverages.
Your liver is working to break down the alcohol you consumed so your kidneys can clear it out ASAP. But in the process, your body’s inflammatory and metabolic reactions are going to lay you low with a hangover.
As long as people have suffered from hangovers, they’ve searched in vain for a cure. Revelers have access to a variety of compounds, products and devices that purport to ease the pain.
But there’s a lot of purporting and not a lot of proof. Most have not been backed up well by science in terms of usefulness for hangover treatment, and often their effects don’t seem like they’d match up with what scientists know about the biology of the hangover.
Hangovers are virtually guaranteed when you drink too much. That amount varies from person to person based on genetic factors as well as whether there are other compounds that formed along with ethanol in the fermentation process.
Over the course of a night of heavy drinking, your blood alcohol level continues to rise. Your body labors to break down the alcohol – consumed as ethanol in beer, wine or spirits – forming damaging oxygen free radicals and acetaldehyde, itself a harmful compound.
The longer ethanol and acetaldehyde stick around, the more damage they can do to your cellular membranes, proteins and DNA, so your body’s enzymes work quickly to metabolize acetaldehyde to a less toxic compound, acetate.
Over time, your ethanol levels drop through this natural metabolic process. Depending on how much you consumed, you’re likely to experience a hangover as the level of ethanol in your blood slowly returns to zero. Your body is withdrawing from high levels of circulating alcohol, while at the same time trying to protect itself from the effects of alcohol.
Scientists have limited knowledge of the leading causes of the hangover. But they do know that the body’s responses include changes in hormone levels to reduce dehydration and cellular stress.
Alcohol consumption also affects a variety of neurotransmitter systems in the brain, including glutamate, dopamine and serotonin.
Inflammation increases in the body’s tissues, and the healthy gut bacteria in your digestive system take a hit too, promoting leaky gut.
Altogether, the combination of all these reactions and protective mechanisms activated by your system gives rise to the experience of a hangover, which can last up to 48 hours.
Your misery likely has company Drinking and socializing are cultural acts, and most hangovers do not happen in isolation. Human beings are social creatures, and there’s a high likelihood that at least one other individual feels the same as you the morning after the night before.
Each society has different rules regarding alcohol use, which can affect how people view alcohol consumption within those cultures.
Drinking is often valued for its relaxing effect and for promoting sociability. So it’s common to see alcohol provided at celebratory events, social gatherings and holiday parties.
In the United States, drinking alcohol is largely embraced by mainstream culture, which may even promote behaviors involving excessive drinking. It should be no surprise that overindulgence goes hand in hand with these celebratory social events – and leads to hangover regrets a few hours later.
Your body’s reactions to high alcohol intake and the sobering-up period can influence mood, too. The combination of fatigue that you experience from sleep deprivation and hormonal stress reactions, in turn, affect your neurobiological responses and behavior. As your body is attempting to repair itself, you’re more likely to be easily irritated, exhausted and want nothing more than to be left alone.
Of course, your work productivity takes a dramatic hit the day after an evening of heavy drinking.
When all is said and done, you’re the cause of your own hangover pain, and you’re the one who must pay for all the fun of the night before. But in short order, you’ll forget how excruciating your last hangover was. And you may very soon talk yourself into doing the things you swore you’d never do again. Speeding up recovery While pharmacologists like us understand a bit about how hangovers work, we still lack a true remedy.
Countless articles describe a variety of foods, caffeine, ion replenishment, energy drinks, herbal supplements including thyme and ginger, vitamins and the “hair of the dog” as ways to prevent and treat hangovers.
But the evidence isn’t really there that any of these work effectively. They’re just not scientifically validated or well reproduced.
For example, Kudzu root (Pueraria lobata), a popular choice for hangover remedies, has primarily been investigated for its effects in reducing alcohol-mediated stress and hangover.
But at the same time, Kudzu root appears to inhibit the enzymes that break down acetaldehyde – not good news since you want to clear that acetaldehyde from your system quickly.
To fill this knowledge gap, our lab is working with colleagues to see if we can find scientific evidence for or against potential hangover remedies. We’ve focused on the benefits of dihydromyricetin, a Chinese herbal medicine that is currently available and formulated as a dietary supplement for hangover reduction or prevention.
Dihydromyricetin appears to work its magic by enhancing alcohol metabolism and reducing its toxic byproduct, acetaldehyde. From our findings in mice models, we are collecting data that support the usefulness of dihydromyricetin in increasing the expression and activity of enzymes responsible for ethanol and acetaldehyde metabolism in the liver, where ethanol is primarily broken down.
These findings explain one of the several ways dihydromyricetin protects the body against alcohol stress and hangover symptoms.
We are also studying how this enhancement of alcohol metabolism results in changes in alcohol drinking behaviors. Previously, dihydromyricetin was found to counteract the relaxation affect of drinking alcohol by interfering with particular neuroreceptors in the brain; rodents didn’t become as intoxicated and consequently reduced their ethanol intake.
Through this combination of mechanisms, we hope to illustrate how DHM might reduce the downsides of excessive drinking beyond the temporary hangover, and potentially reduce drinking behavior and damage associated with heavy alcohol consumption.
Of course, limiting alcohol intake and substituting water for many of those drinks during an evening out is probably the best method to avoid a painful hangover.
However, for those times when one alcoholic beverage leads to more than a few more, be sure to stay hydrated and catch up on rest.
Your best bet for a smoother recovery is probably some combination of nonsteroidal anti-inflammatory drug like ibuprofen, Netflix, and a little downtime.

Shopping season for Medicare coverage is about to begin. With it comes the annual onslaught of TV ads and choices to consider.
People eligible for the federal government’s Medicare program will have from Oct. 15 to Dec. 7 to sign up for 2025 Medicare Advantage plans, which are privately run versions of the program. They also can add a prescription drug plan to traditional Medicare coverage.
Many people on Medicare Advantage plans will probably have to find new coverage as major insurers cut costs and pull back from markets. Industry experts also predict some price increases for Medicare prescription drug plans.
Shoppers often have dozens of options during this sign-up period. Here are some things to consider.
Don’t put off shopping for Medicare coverage
Start thinking about next year’s coverage before the annual enrollment window begins. Insurers will usually preview their offerings or let customers know about any big changes. That makes anything arriving in the mail from your insurer important to read.
Insurance agents say many people wait until after Thanksgiving to decide coverage plans for the new year. That could be a mistake this year: The holiday falls on Nov. 28, leaving slightly more than a week to decide before the enrollment window closes.
Look beyond the premium
Many Medicare Advantage plans promote a $0 premium. That may sound attractive, but price is only one variable to consider.
Shoppers should look at whether their doctors are in the plan’s coverage network and how prescriptions would be covered. They also should know the maximum amount under the plan that they’d have to pay if a serious health issue emerges.
Plans offer many supplemental benefits, including help paying food or utility bills. Don’t let those distract from understanding the core coverage, said Danielle Roberts, co-founder of the Fort Worth, Texas, insurance agency Boomer Benefits.
“Remember that we buy health insurance for the big things, not the frills,” she said.
How to get help shopping for plans
The federal government operates a plan finder that lets people compare options. The State Health Insurance Assistance Program can be another resource. Insurance brokers or agents also guide customers through searches.
Sometimes a plan’s coverage doesn’t work as expected. If that happens, there’s another enrollment window in the first three-months of each year where some shoppers may be able to make a change.

WASHINGTON (AP) — Americans can once again order COVID-19 tests, without being charged, sent straight to their homes.
The U.S. government reopened the program on Thursday, allowing any household to order up to four at-home COVID nasal swab kits through the website, covidtests.gov. The tests will begin shipping, via the United States Postal Service, as soon as next week.
The website has been reopened on the heels of a summer COVID-19 virus wave and heading into the fall and winter respiratory virus season, with health officials urging Americans to get an updated COVID-19 booster and their yearly flu shot.
“Before you visit with your family and friends this holiday season, take a quick test and help keep them safe from COVID-19,” U.S. Health and Human Services Assistant Secretary for Preparedness and Response Dawn O’Connell said in a statement.
U.S. regulators approved an updated COVID-19 vaccine that is designed to combat the recent virus strains and, they hope, forthcoming winter ones, too. Vaccine uptake is waning, however. Most Americans have some immunity from prior infections or vaccinations, but under a quarter of U.S. adults took last fall’s COVID-19 shot.
Using the swab, people can detect current virus strains ahead of the fall and winter respiratory virus season and the holidays. Over-the-counter COVID-19 at-home tests typically cost around $11, as of last year. Insurers are no longer required to cover the cost of the tests.
Before using any existing at-home COVID-19 tests, you should check the expiration date. Many of the tests have been given an extended expiration from the date listed on the box. You can check on the Food and Drug Administration’s website to see if that’s the case for any of your remaining tests at home.
Since COVID-19 first began its spread in 2020, U.S. taxpayers have poured billions of dollars into developing and purchasing COVID-19 tests as well as vaccines. The Biden administration has given out 1.8 billion COVID-19 tests, including half distributed to households by mail. It’s unclear how many tests the government still has on hand.
