The best things to drink after a hangover are water, electrolyte-rich beverages, and fruit juice. Alcohol suppresses the hormone that tells your kidneys to hold onto water, which means you lose significantly more fluid than you take in while drinking. Replacing that lost fluid and the minerals that went with it is the fastest way to start feeling human again.
Why Alcohol Leaves You So Dehydrated
Alcohol directly blocks the release of vasopressin, the hormone that signals your kidneys to reabsorb water. Without it, your kidneys essentially let fluid pass straight through. Early research estimated that every 10 grams of alcohol (roughly one standard drink) produces an extra 100 milliliters of urine beyond what you’d normally lose. Over a night of several drinks, that adds up to a substantial fluid deficit before you even factor in sweating, skipping water, or staying up late.
This isn’t just about thirst. When you lose that much water, you also flush out electrolytes like sodium and potassium, which your muscles, nerves, and brain need to function properly. That’s why a hangover doesn’t just make you thirsty. It makes you foggy, achy, and nauseous. Rehydration works best when you replace both the water and the minerals.
Water: Start Here
Plain water is the obvious first step and genuinely the most important one. Sip it steadily rather than chugging a huge amount at once, which can make nausea worse. Your body absorbs water more efficiently in smaller, consistent amounts. If you can keep a glass of water by your bed and drink some before you fall asleep, you’ll wake up in noticeably better shape. But even if you didn’t, starting the morning with water begins closing the gap.
On its own, water doesn’t replace lost electrolytes. That’s fine for mild hangovers, but if you’re dealing with a headache, muscle cramps, or serious fatigue, pairing water with something that contains sodium and potassium will help more.
Electrolyte Drinks and Sports Drinks
Sports drinks and oral rehydration solutions contain sodium, potassium, and a small amount of sugar, all of which help your body absorb and retain water faster than water alone. The sodium is especially important because it triggers your body to hold onto fluid rather than just passing it through. Any standard sports drink or electrolyte powder mixed into water will do the job.
If you want something with fewer artificial ingredients, coconut water is a strong natural option. A single cup of store-bought coconut water contains about 470 milligrams of potassium and 30 milligrams of sodium. That potassium content is unusually high, which makes it effective for replenishing what alcohol flushed out. The trade-off is that it’s relatively low in sodium compared to a sports drink, so pairing it with a salty snack or a pinch of salt can round things out.
Fruit Juice and the Fructose Effect
Fruit juice does more than just rehydrate. The natural sugar in juice, fructose, appears to speed up how fast your body processes any remaining alcohol in your system. One study found that fructose increased the rate of alcohol metabolism by an average of 80%, though results varied significantly from person to person depending on how well they absorbed the sugar.
Apple juice, orange juice, and grape juice are all good choices. Orange juice has the added benefit of potassium and vitamin C. The sugar in juice also helps stabilize blood glucose, which tends to drop after heavy drinking as your liver prioritizes breaking down alcohol over regulating blood sugar. That low blood sugar contributes to the shaky, weak feeling many people experience the morning after. A glass of juice addresses dehydration, mineral loss, and blood sugar all at once.
One caveat: if your stomach is sensitive, the acidity in citrus juice can make nausea worse. Apple juice or pear juice tends to be gentler.
Pickle Juice and Broth
Pickle juice has a reputation as a hangover cure, and the reasoning is sound. One cup of pickle brine contains roughly a third of your daily recommended sodium intake, making it one of the most electrolyte-dense things you can drink. That concentrated sodium helps your body retain fluid and speeds up rehydration. You don’t need a full cup. Even a few ounces can make a noticeable difference, especially early in the morning when you’re most depleted.
Bone broth or any simple soup broth works on the same principle. It delivers sodium, potassium, and water in a warm, easy-to-digest form. If you’re too nauseous for solid food, sipping warm broth is one of the gentlest ways to get calories, salt, and fluid into your system simultaneously. Miso soup is another excellent option for the same reasons.
What to Avoid
Coffee is tempting because you’re exhausted, but caffeine is a mild diuretic, meaning it can push you further into dehydration if you drink it before rehydrating with something else. A cup of coffee after you’ve had water and electrolytes is fine. A cup of coffee as your first drink of the morning will make things worse before they get better.
“Hair of the dog,” or drinking more alcohol, delays symptoms rather than resolving them. It temporarily suppresses the rebound effects your nervous system is going through, but once that additional alcohol wears off, you’re back where you started with even more dehydration to recover from.
Sugary sodas and energy drinks are less effective than they seem. They provide sugar and caffeine but very little sodium or potassium. The carbonation can also aggravate an already unsettled stomach.
A Practical Morning-After Sequence
If you want a simple plan: start with a full glass of water as soon as you wake up. Follow it 15 to 20 minutes later with something containing electrolytes, whether that’s a sports drink, coconut water, or a few ounces of pickle juice. Then have a glass of fruit juice with a light meal when your stomach can handle it. This combination covers fluid replacement, mineral restoration, blood sugar recovery, and faster clearance of any lingering alcohol. Most people feel a meaningful improvement within one to two hours of consistent rehydration.
