The most effective hangover remedies target the specific problems alcohol creates in your body: dehydration, inflammation, low blood sugar, and the toxic byproducts your liver produces while breaking down alcohol. No single cure eliminates a hangover entirely, but several strategies can meaningfully reduce how miserable you feel and how quickly you recover.
Why Hangovers Happen
Hangover symptoms begin as your blood alcohol concentration drops back toward zero, which is why you typically feel worst the morning after drinking rather than while you’re still intoxicated. Several overlapping processes drive the headache, nausea, fatigue, and brain fog.
Alcohol suppresses your body’s production of antidiuretic hormone, the chemical signal that tells your kidneys to hold onto water. Without it, your kidneys flush out extra free water, which is why you urinate so frequently while drinking. This diuresis is the main driver of dehydration, and in people who drink heavily or have poor nutrition, it can also lead to electrolyte imbalances. Meanwhile, your liver converts alcohol into acetaldehyde, a toxic compound that’s eventually broken down further into harmless acetate. When you drink faster than your liver can keep up, acetaldehyde accumulates and contributes to nausea, flushing, and general discomfort. Alcohol also interferes with your body’s ability to maintain normal blood sugar levels by disrupting the liver processes that release stored glucose into your bloodstream.
Rehydrate Before and After
Water is the simplest and most important hangover intervention. Because alcohol triggers your kidneys to dump extra fluid, you can lose significantly more liquid than you take in during a night of drinking. Alternating alcoholic drinks with glasses of water slows this deficit, and drinking a full glass of water before bed helps even more. The next morning, steady sipping is better than chugging a huge amount at once, which can upset an already irritated stomach.
Sports drinks or oral rehydration solutions add back sodium and potassium, which can help if you’ve been vomiting or had diarrhea. For most people with a standard hangover, plain water and a meal will restore electrolytes just fine. Coconut water is another option that provides potassium naturally.
Eat Something, Especially Carbs
Alcohol disrupts your liver’s normal glucose production, which can leave your blood sugar lower than usual the next morning. That drop contributes to the shakiness, weakness, and foggy thinking that make hangovers so unpleasant. Eating a meal with complex carbohydrates (toast, oatmeal, rice, crackers) gives your body a steady source of glucose to restore those levels. Bland foods are also easier on a sensitive stomach than anything greasy or acidic.
If you can manage a more substantial meal, adding some protein and healthy fat will slow digestion and provide more sustained energy. Eggs, bananas, and avocado are popular choices, and bananas have the added benefit of being rich in potassium.
Over-the-Counter Pain Relief
A standard dose of ibuprofen or aspirin can ease a hangover headache. Both are anti-inflammatory, which addresses part of the underlying problem. However, the Mayo Clinic notes that aspirin and ibuprofen can irritate your stomach lining, and alcohol has already done some of that work for you. Taking them with food reduces that risk.
Acetaminophen (Tylenol) is a different story. Your liver processes both acetaminophen and alcohol, and combining them puts extra strain on an organ that’s already working overtime. Cleveland Clinic physicians note that an occasional dose or two the morning after social drinking is generally fine for healthy people, but anyone who drinks heavily or regularly should keep their acetaminophen intake well below the normal daily limit. Chronic heavy drinking depletes a protective compound in the liver called glutathione, and without that buffer, acetaminophen is more likely to cause liver damage. If you drink frequently, ibuprofen is the safer choice.
Coffee and Caffeine
Caffeine won’t detoxify your body or speed up alcohol metabolism, but it does counteract the fatigue and grogginess that make hangovers hard to push through. If you’re a regular coffee drinker, skipping your morning cup can add a caffeine withdrawal headache on top of the hangover headache, so having your normal amount makes sense. Just keep in mind that caffeine is a mild diuretic itself, so pair it with extra water.
Sleep and Rest
Alcohol fragments your sleep architecture, reducing the amount of deep, restorative sleep you get even if you’re in bed for eight hours. Much of hangover fatigue comes from this poor sleep quality rather than from alcohol’s direct effects. If your schedule allows it, extra sleep the next day is one of the most effective recovery tools available. Your body clears acetaldehyde and restores normal hormone levels faster when you’re resting.
Supplements That Show Some Promise
The supplement market is flooded with hangover products, and most have little evidence behind them. Two exceptions stand out, though neither is a guaranteed fix.
Red ginseng has the most encouraging human data. A randomized crossover study in 25 healthy men found that a red ginseng drink taken alongside alcohol significantly lowered blood alcohol concentrations at 30, 45, and 60 minutes compared to a placebo, and participants reported reduced hangover severity. The researchers observed faster alcohol clearance as the likely mechanism.
Dihydromyricetin (DHM), a flavonoid extracted from the Japanese raisin tree, has shown strong results in animal studies. In rats, DHM at modest doses counteracted acute alcohol intoxication and reduced withdrawal symptoms including anxiety and seizure susceptibility. It appears to work by interacting with the same brain receptors that alcohol targets, essentially blunting alcohol’s effects on the nervous system. Human clinical trials are still limited, so the real-world benefit remains uncertain, but DHM is the active ingredient in many popular hangover supplements.
B vitamins and zinc are sometimes recommended because alcohol depletes both, and a few observational studies have linked higher dietary intake of these nutrients with less severe hangovers. A standard multivitamin covers this base without the need for specialized products.
What Doesn’t Work
“Hair of the dog,” or drinking more alcohol the next morning, delays your hangover rather than preventing it. It temporarily raises your blood alcohol level, which masks symptoms, but once that drink wears off you’re back where you started with an even larger toxin load for your liver to process.
IV drip bars have become popular in some cities, offering intravenous saline and vitamins as a premium hangover cure. While IV fluids do rehydrate you quickly, there’s no evidence they work better than simply drinking water and eating a meal. You’re paying for speed and a placebo effect.
Activated charcoal is another frequent suggestion, but alcohol is absorbed rapidly from the stomach and small intestine. By the time you’re hungover, charcoal has nothing left to bind to.
Prevention Is the Best Remedy
The most reliable way to reduce hangover severity is to drink less, drink slower, and drink with food in your stomach. Food slows alcohol absorption, giving your liver more time to keep up. Darker liquors like bourbon and red wine contain higher levels of congeners, byproducts of fermentation that appear to worsen hangovers compared to lighter options like vodka or white wine. Alternating every alcoholic drink with a glass of water cuts your total intake and maintains hydration at the same time.
Your body clears alcohol at a roughly fixed rate, about one standard drink per hour, regardless of what you eat or drink afterward. No supplement or remedy speeds that up meaningfully. The practical takeaway: give your body enough time between your last drink and when you need to function the next day, and stack the simple interventions (water, food, sleep, a pain reliever if needed) to manage the gap between how you feel and how you want to feel.
