The best things for a hangover are water, electrolytes, easy-to-digest food, sleep, and time. There’s no instant cure, but the right combination of remedies can shorten your misery and help your body recover faster. Hangover symptoms actually peak once your blood alcohol level drops back to zero, and they can last 24 hours or longer.
Why Hangovers Feel So Terrible
When your liver processes alcohol, it first converts it into a toxic compound called acetaldehyde before eventually breaking it down into harmless acetic acid. That intermediate step is the problem. Acetaldehyde builds up in your system faster than your body can clear it, contributing to nausea, headache, and that general feeling of being poisoned (because, technically, you are).
On top of that, alcohol triggers inflammation throughout your body. In one study, people who drank alcohol saw a 50% spike in C-reactive protein, a key marker of inflammation, along with doubled cortisol (stress hormone) levels. Both of these correlated directly with hangover severity. Meanwhile, alcohol acts as a diuretic, flushing out water along with important minerals like magnesium and potassium. Poor food intake, impaired absorption in your gut, and accelerated urinary loss of electrolytes all compound the dehydration.
Then there’s the sleep problem. Alcohol sedates you initially, increasing deep sleep during the first half of the night while suppressing REM sleep. But during the second half of the night, your brain rebounds. You wake up more often, cycle between sleep stages erratically, and lose the restorative rest your body desperately needs. That’s why you can sleep eight hours after drinking and still feel exhausted.
Water and Electrolytes First
Rehydrating is the single most impactful thing you can do. Alcohol suppresses an antidiuretic hormone in your brain, which means your kidneys dump water you’d normally retain. You’re losing not just fluid but also magnesium, potassium, and sodium along with it. One clinical study found that patients with the worst symptoms of acute alcohol intake almost universally had low serum magnesium levels.
Plain water helps, but drinks containing electrolytes work better because they replace what you actually lost. Sports drinks, coconut water, or oral rehydration solutions all fit the bill. If you don’t have any of those, adding a pinch of salt to water with a squeeze of citrus gets you partway there. Start rehydrating before bed if you can, and keep drinking fluids throughout the morning.
What to Eat When You Feel Awful
Eggs are one of the best hangover foods, and there’s real science behind this. They’re rich in an amino acid called L-cysteine, which directly neutralizes acetaldehyde by binding to it and converting it into a stable, harmless compound. A study published in PLOS ONE confirmed this mechanism, showing that even 200 mg of L-cysteine was enough to significantly reduce acetaldehyde levels after alcohol consumption. Two or three eggs contain roughly that amount of cysteine naturally.
Beyond eggs, your goal is bland, easy-to-digest food that won’t upset your already irritated stomach. Toast, bananas, oatmeal, and broth are all solid choices. Bananas are especially useful because they’re high in potassium, one of the minerals you’ve flushed out. Avoid greasy, heavy meals, which can make nausea worse even though folklore says otherwise.
Ginger, whether as tea, candied pieces, or in ginger ale (the kind made with real ginger), has a long track record for calming nausea. If your main symptom is an upset stomach, sipping ginger tea slowly can make a real difference.
Pain Relief That Won’t Backfire
Reaching for a painkiller is tempting, but your choice matters. Acetaminophen (Tylenol) is processed by your liver, the same organ that’s already working overtime to clear alcohol from your system. Combining the two increases the risk of liver damage, especially if you drink regularly or take more than the recommended dose.
Ibuprofen (Advil, Motrin) or naproxen (Aleve) are generally considered safer options for hangover headaches, since they’re processed differently. That said, these can irritate your stomach lining, which alcohol has already inflamed. Take them with food and water, not on an empty stomach, and stick to the lowest effective dose.
Sleep Is Doing More Than You Think
Going back to bed isn’t laziness. It’s one of the most effective hangover remedies available. Since alcohol wrecked your sleep architecture the night before, stealing your REM sleep and fragmenting the second half of your night, your brain is running on genuinely poor-quality rest. A morning or afternoon nap lets your body complete sleep cycles it was denied, and it gives your liver more time to finish clearing toxins without you suffering through it consciously.
Your Drink Choice Affects Tomorrow
Not all alcohol produces equally bad hangovers. The difference comes down to congeners, byproducts created during fermentation and aging that your body has to process alongside the alcohol itself. Dark spirits contain dramatically more of these compounds than clear ones.
- High congeners: brandy, red wine, dark rum
- Medium congeners: whiskey, white wine, gin
- Low congeners: vodka, beer
The numbers are striking. Brandy contains up to 4,766 milligrams per liter of methanol (one type of congener), while beer has just 27 milligrams per liter. Rum packs as much as 3,633 milligrams per liter of another congener called 1-propanol, while vodka ranges from zero to 102. If you’re trying to minimize hangover severity, sticking to lighter-colored drinks and avoiding sugary mixers (which add their own burden) helps noticeably.
What About Prickly Pear and Other Supplements
Prickly pear cactus extract is one of the few natural remedies with clinical data behind it. In a controlled study, taking prickly pear extract before drinking reduced C-reactive protein (that inflammation marker) back to pre-drinking levels. Since inflammation is a major driver of hangover symptoms, this translated to less severe hangovers for the people who took it. The catch: you need to take it before you drink, not after.
Various “hangover cure” supplements sold online contain combinations of B vitamins, electrolytes, and amino acids like L-cysteine. Some of these ingredients have legitimate mechanisms, but no single pill eliminates a hangover. The most useful ingredients in these products, electrolytes and cysteine, you can get from a glass of electrolyte water and a plate of scrambled eggs.
A Practical Hangover Recovery Plan
Before bed, drink a full glass of water (two if you can manage it) and eat a small snack. When you wake up, drink more water or an electrolyte beverage before anything else. Eat eggs and toast or a banana when your stomach can handle it. Take ibuprofen with that food if you have a headache. Then go back to sleep if your schedule allows it.
Your body clears roughly one standard drink per hour, so if you had eight drinks, you’re looking at eight or more hours before your blood alcohol even reaches zero, which is when hangover symptoms actually peak. For a heavy night of drinking, expect to feel off for most of the following day. The remedies above won’t eliminate that timeline, but they address the specific biological problems, dehydration, acetaldehyde buildup, inflammation, and lost sleep, that make hangovers feel as bad as they do.
