The most effective hangover helpers are unsexy but well-supported: water, electrolytes, anti-inflammatory pain relievers, food, and time. There’s no instant cure, but the right combination of these can meaningfully shorten your misery and get you functional faster.
A hangover is essentially your body dealing with the aftermath of processing a toxic substance. When you drink, your liver converts alcohol into a compound called acetaldehyde, which is even more toxic than the alcohol itself. Acetaldehyde eventually gets broken down into harmless acetic acid, but while it lingers, it contributes directly to nausea, headache, and that general feeling of being poisoned. Because that’s more or less what’s happening.
Rehydrate With More Than Just Water
Alcohol is a diuretic, meaning it makes you urinate more than the volume of fluid you’re taking in. By morning, you’re dehydrated, and dehydration alone accounts for a good chunk of the headache, fatigue, and dizziness. Plain water helps, but it’s not the whole picture. You’ve also lost electrolytes, particularly sodium and potassium, and replacing those speeds up actual rehydration at the cellular level.
Sports drinks work. So do electrolyte packets you dissolve in water. The principle behind oral rehydration solutions is a specific balance of sodium and glucose that helps your intestines absorb water more efficiently. You don’t need to be precise about it. A glass of water with a pinch of salt and a splash of juice, a bowl of broth, or a commercial electrolyte drink all accomplish the same basic goal. Start drinking fluids as soon as you wake up and keep sipping throughout the morning rather than chugging a liter at once, which can make nausea worse.
Choose the Right Pain Reliever
For a hangover headache, ibuprofen (Advil) or naproxen (Aleve) are your best options. Both are anti-inflammatory, which matters because inflammation is a core driver of hangover symptoms, not just pain. Aspirin works too, though it can irritate an already-sensitive stomach.
Avoid acetaminophen (Tylenol). Your liver is already working overtime to clear alcohol and its byproducts, and acetaminophen is processed through the same liver pathways. The combination can cause real liver damage. This is especially important if you drink regularly. The Cleveland Clinic notes that heavy or binge drinkers should keep acetaminophen doses under 2,000 mg per day even under normal circumstances. After a night of drinking, it’s safest to skip it entirely.
Eat Something, Even If You Don’t Want To
Alcohol disrupts your blood sugar regulation. Your liver, busy metabolizing alcohol, deprioritizes its normal job of releasing stored glucose into your bloodstream. Research published by the American Diabetes Association has shown that evening alcohol consumption leads to significantly lower blood sugar levels the next morning. Even in people without diabetes, this dip contributes to shakiness, weakness, irritability, and brain fog.
Bland, carbohydrate-rich foods like toast, crackers, oatmeal, or bananas help stabilize blood sugar without overwhelming a queasy stomach. If you can manage something more substantial, eggs are a solid choice. They’re high in cysteine, an amino acid found in many protein-rich foods that supports your body’s production of glutathione, one of the key antioxidants your liver uses to neutralize alcohol byproducts. Meat, dairy, legumes, and nuts are also good sources.
What You Drank Matters
Not all alcohol produces the same hangover. Darker spirits like bourbon, brandy, cognac, and red wine contain high levels of congeners, chemical byproducts of fermentation that your body has to process separately from the alcohol itself. One of the most problematic congeners is methanol, which your body breaks down into formaldehyde and formic acid. Dark liquors contain the highest quantities.
Clear drinks like vodka, gin, white wine, light rum, and light beer have significantly fewer congeners. This doesn’t mean they’re hangover-proof, but at equivalent amounts of alcohol, you’ll generally feel worse after a night of bourbon than a night of vodka. If you’re planning ahead, choosing lighter-colored drinks is one of the few preventive moves that actually has a physiological basis.
Why “Hair of the Dog” Backfires
Drinking more alcohol the next morning does temporarily reduce hangover symptoms. This isn’t a myth. But the mechanism is the same one behind alcohol withdrawal: your brain adapts to the presence of alcohol, and when it’s removed, rebound effects kick in. A morning drink simply delays the inevitable while adding more toxic byproducts to the queue your liver is already working through.
Research from the University of Southampton confirmed that small doses of alcohol can relieve withdrawal-like symptoms, but also showed that this pattern increases dependency over time. In practical terms, you’re trading a shorter hangover today for a longer one later, plus a higher tolerance that means worse hangovers in the future.
Supplements: What Has Evidence
Most hangover supplements are marketing with minimal science. Two exceptions stand out, though neither is a miracle.
Prickly pear extract, taken before drinking, has the strongest published evidence. A study in JAMA Internal Medicine found that participants who took prickly pear extract before drinking had C-reactive protein levels (a marker of inflammation) 40% lower than those who took a placebo. Some hangover symptoms improved, particularly nausea and dry mouth, though the effect on headache was less consistent.
Dihydromyricetin (DHM), derived from the Japanese raisin tree, is widely sold as a hangover supplement and is currently being studied in clinical trials for its effects on alcohol metabolism and liver protection. Early research suggests it may help the liver process alcohol more efficiently through effects on cellular energy pathways, but human data is still limited. It’s not harmful, but “promising” is the most honest description right now.
The Practical Hangover Playbook
If you’re reading this while hungover, here’s the sequence that will help most:
- Immediately: Drink a large glass of water with electrolytes. Broth, coconut water, or a sports drink all work.
- Within 30 minutes: Take ibuprofen or naproxen with a small amount of food, even just a few crackers. Taking anti-inflammatories on a completely empty stomach can cause its own nausea.
- Within an hour: Eat a real meal. Eggs, toast, oatmeal, or a banana are all good starting points. Pair carbohydrates with some protein.
- Throughout the day: Keep drinking fluids. Alternate water with something containing electrolytes. Avoid coffee until you’ve had at least a couple glasses of water, since caffeine is also a diuretic and can worsen dehydration before it helps your alertness.
Most hangovers resolve within 24 hours. The severity depends on how much you drank, how hydrated you were while drinking, what you ate beforehand, and your individual biology. Some people break down acetaldehyde faster than others due to genetic differences in enzyme activity. Many people of East Asian descent, for example, carry a slower-acting version of the enzyme that clears acetaldehyde, which is why alcohol causes more intense flushing and worse hangovers in this population.
Sleep also matters more than most people realize. Alcohol fragments your sleep architecture, reducing the amount of deep, restorative sleep you get even if you’re unconscious for eight hours. If you can nap the next day, it genuinely helps your body catch up on the recovery it couldn’t do overnight.
