The most effective hangover remedies target the specific problems alcohol creates: dehydration, inflammation, poor sleep, and a disrupted stomach. No single cure exists, but a combination of rehydration, the right pain reliever, food, and rest can meaningfully shorten your misery. Here’s what actually works, what doesn’t, and why.
Why Hangovers Feel So Bad
Understanding what’s happening in your body helps explain why certain remedies work. When your blood alcohol level rises and then drops sharply, it triggers a cascade of problems. Your immune system releases inflammatory molecules, similar to what happens when you’re fighting an infection. That’s why hangovers can feel like a mild flu, with body aches, headache, nausea, and fatigue.
Alcohol is also a diuretic, meaning it makes you urinate more than the volume of fluid you’re taking in. Over the course of an evening, this creates a significant fluid and electrolyte deficit. On top of that, alcohol fragments your sleep. Even if you were in bed for eight hours, the quality of that sleep was poor. Alcohol suppresses the deep, restorative stages of sleep your brain needs for memory consolidation and cognitive recovery, which is why you wake up foggy and exhausted even after a full night.
Rehydrate With Electrolytes, Not Just Water
Drinking water helps, but it only replaces fluid without restoring the sodium and potassium you’ve lost. Plain water also gets flushed through your kidneys quickly when your sodium levels are low, so you don’t retain as much as you’d expect. An oral rehydration solution like Pedialyte is a better choice. It contains two to three times more electrolytes and about 25 to 50 percent less sugar than most sports drinks, which matters because high sugar content slows fluid absorption and can further upset a sensitive stomach.
Sports drinks are a step up from water but not ideal. Their higher sugar content provides energy but can irritate your gut when you’re already nauseous. If all you have is water, drink it. But if you can grab an electrolyte solution, your body will absorb and hold onto the fluid faster. Drinking a glass of water or electrolytes between alcoholic drinks the night before, and again before bed, also reduces how dehydrated you wake up.
Choose the Right Pain Reliever
For a hangover headache, ibuprofen or aspirin (both NSAIDs) are generally the safer choice over acetaminophen. NSAIDs reduce both pain and inflammation, which directly targets part of what’s causing your symptoms.
Acetaminophen (Tylenol) is riskier after drinking because both alcohol and acetaminophen are processed by your liver. Chronic or heavy drinking depletes a protective compound in your liver called glutathione, and when acetaminophen enters a liver that’s already been taxed by alcohol, the risk of liver damage increases. Acetaminophen toxicity accounts for nearly half of acute liver failure cases in North America. A single normal dose after a night of moderate drinking is unlikely to cause serious harm, but if you drink heavily or regularly, keeping your daily acetaminophen intake below 2,000 mg is a safer threshold.
NSAIDs do come with their own trade-off: they’re harder on your stomach lining and kidneys. If you already have gastrointestinal issues, take them with food.
Eat Something, Even If You Don’t Want To
Food helps in two ways. First, it stabilizes your blood sugar, which alcohol disrupts overnight. Low blood sugar contributes to the shakiness, weakness, and irritability of a hangover. Second, having something in your stomach before taking an NSAID protects your gut lining. Bland, easy-to-digest foods work best when you’re nauseous: toast, crackers, bananas, rice, or eggs. Eggs contain an amino acid that helps your liver process the byproducts of alcohol metabolism, and bananas are a natural source of potassium, one of the key electrolytes you’ve lost.
Greasy food is a popular hangover choice, but it’s better as prevention than cure. A fatty meal before drinking slows alcohol absorption. The morning after, greasy food can make nausea worse.
Sleep More If You Can
Even though you may have slept for hours, the sleep you got while alcohol was in your system was fragmented and shallow. Your brain cycles through several stages of sleep each night, and alcohol disrupts the stages responsible for memory, emotional processing, and physical restoration. This is a major reason you feel mentally sluggish the next day, not just tired but unable to think clearly.
If your schedule allows it, going back to sleep after waking up hungover lets your brain get the restorative sleep it missed. Even a 90-minute nap (roughly one full sleep cycle) can improve how you feel. Caffeine can help with alertness and headache in the short term, but it’s also a mild diuretic, so pair it with extra fluids.
What Your Drink Choice Has to Do With It
Not all alcohol produces equally bad hangovers. Darker liquors like bourbon, whiskey, and red wine contain higher levels of congeners, which are chemical byproducts of fermentation. Research comparing bourbon and vodka drinkers found that bourbon, a high-congener liquor, produced more severe hangovers than vodka, which contains very few congeners. Light-colored drinks like vodka, gin, and white wine tend to cause milder symptoms at the same alcohol volume. This doesn’t mean clear liquor is hangover-proof, but it’s one variable you can control.
What Doesn’t Work
“Hair of the dog,” or drinking more alcohol the next morning, is one of the most persistent hangover myths. It doesn’t cure anything. Drinking again temporarily masks your symptoms by putting alcohol back into your system, but once that drink wears off, the hangover returns, often worse because you’ve added more alcohol for your body to process. A hangover develops when your elevated blood alcohol concentration drops sharply. Delaying that drop just postpones the inevitable.
Vitamin B6 supplements are another common recommendation, but Mayo Clinic notes that claims about B6 treating alcohol intoxication or hangover symptoms remain unproven. Dihydromyricetin (DHM), a plant compound found in many commercial hangover pills, has a long history in traditional Chinese medicine and shows some promise in animal studies for reducing alcohol-related liver inflammation. But clinical evidence in humans for reducing hangover severity specifically is lacking, so these products may not deliver what their marketing suggests.
A Practical Hangover Recovery Plan
If you’re reading this while hungover, here’s the short version of what to do right now:
- Drink an electrolyte solution like Pedialyte or a low-sugar sports drink. Sip steadily rather than chugging.
- Take ibuprofen with a small amount of food to ease headache and body aches.
- Eat bland, potassium-rich food like bananas, toast, or eggs to stabilize blood sugar and settle your stomach.
- Go back to sleep if possible. Your brain needs real rest, not the disrupted sleep alcohol gave you.
- Skip the Bloody Mary. More alcohol only delays your recovery.
Most hangovers resolve within 24 hours. The severity depends on how much you drank, how hydrated you were, what you ate beforehand, and what type of alcohol you chose. None of these remedies are magic, but together they address the actual mechanisms making you feel terrible, and that’s the closest thing to a cure that exists.
