Water is the single most important thing to drink after a hangover, but it’s not the only thing that helps. Alcohol suppresses a hormone that tells your kidneys to hold onto water, so you lose more fluid than you take in while drinking. That fluid loss drags electrolytes like sodium and potassium with it. At the same time, your liver breaks alcohol down into a toxic byproduct called acetaldehyde, which triggers inflammation, and your blood sugar drops because alcohol disrupts your body’s ability to produce glucose. The best recovery drinks tackle all three problems: dehydration, electrolyte loss, and low blood sugar.
Water First, Then Add Electrolytes
Plain water is your starting point. Sip it steadily rather than gulping a huge amount at once, which can make nausea worse. But water alone doesn’t replace the sodium and potassium you’ve lost, so pairing it with an electrolyte source speeds things along.
Sports drinks and oral rehydration solutions (like Pedialyte) both work. Oral rehydration solutions contain about three times as much sodium as a typical sports drink (roughly 60 mM versus 18 mM), which you’d expect to make a big difference. In practice, research comparing the two during dehydration found no significant difference in fluid retention. The volume of fluid you drink matters more than the exact electrolyte formula. So grab whichever option you have on hand. If you don’t have either, adding a small pinch of salt and a squeeze of lemon to a glass of water creates a rough approximation.
Coconut Water for Potassium
Coconut water is naturally rich in potassium, along with some sodium, chloride, and carbohydrates. Studies comparing it to commercial sports drinks found no differences in fluid retention, and both promoted rehydration equally well. Coconut water is a solid choice if you prefer something with a milder, less artificial taste than a sports drink. It also contains natural sugars, which helps with the blood sugar issue discussed below. One cup typically has around 600 mg of potassium, roughly the same as a medium banana.
Fruit Juice and Blood Sugar Recovery
Alcohol interferes with your liver’s ability to release stored glucose, so your blood sugar can dip overnight and into the morning. That contributes to the shakiness, fatigue, and brain fog you feel the next day. Drinking something with easily absorbed sugar helps correct this. Fruit juice, regular (not diet) soda, or even a spoonful of honey in warm water all deliver fast-acting carbohydrates that bring blood sugar back up. The Mayo Clinic recommends 15 to 20 grams of fast-acting carbs when blood sugar drops too low, which is roughly the amount in half a cup of orange juice or apple juice.
There’s an added benefit to fructose, the natural sugar in fruit juice. A study that held subjects at a constant blood alcohol level found that a dose of fructose increased the rate of alcohol metabolism by an average of 80%, though the effect varied widely between individuals. You’re unlikely to still have significant alcohol in your blood by morning, but if you’re dealing with a lingering “still drunk” feeling, juice may genuinely help your body clear the remaining alcohol faster.
Milk Holds Fluid Better Than Water
This one surprises most people. A study that tested 13 common beverages and ranked them by a “beverage hydration index” found that both full-fat and skim milk retained significantly more fluid than plain water over four hours. Participants who drank water produced about 1,337 grams of urine in that window, while those who drank milk produced only around 1,050 grams. Milk scored a hydration index of roughly 1.5, meaning it kept about 50% more fluid in the body compared to the same volume of water. The combination of protein, fat, electrolytes, and lactose slows gastric emptying, giving your body more time to absorb the liquid. If your stomach can handle it, a glass of milk is one of the most hydrating options available.
Ginger Tea for Nausea
When nausea is your main complaint, ginger tea is worth trying. Ginger has well-documented anti-nausea properties, used clinically for motion sickness, pregnancy-related nausea, and chemotherapy side effects. Steep a few slices of fresh ginger in hot water for five to ten minutes, or use a ginger tea bag. You’re also getting warm fluid, which can feel easier on a sensitive stomach than cold drinks. Adding honey gives you a small sugar boost at the same time.
Coffee: Helpful With Caveats
If you’re a regular coffee drinker, a hangover headache can be partly caffeine withdrawal on top of everything else. Caffeine narrows blood vessels, which is why it’s an ingredient in many over-the-counter headache medications. A cup of coffee can take the edge off that pounding head.
The common worry is that coffee will dehydrate you further. According to the Mayo Clinic, the fluid in a caffeinated drink generally balances out caffeine’s mild diuretic effect at normal doses. High doses of caffeine, or caffeine in someone who doesn’t normally drink it, can increase urine output. So if coffee is part of your routine, a single cup is fine. Just don’t rely on it as your primary source of fluids, and drink water alongside it.
Tomato Juice and Bloody Marys (Hold the Vodka)
Tomato juice has some legitimate things going for it. It contains lycopene, a compound with anti-inflammatory properties that has shown protective effects against alcohol-related liver stress in animal studies. Tomato powder reduced markers of liver injury and inflammation in mice fed alcohol. Tomato juice also provides potassium, sodium, and simple sugars, checking several recovery boxes at once. A glass of tomato juice with a pinch of salt and some hot sauce is essentially a Bloody Mary without the alcohol, and that’s exactly the point.
Skip the “Hair of the Dog”
Hangover symptoms peak when your blood alcohol level hits zero. Drinking more alcohol the next morning raises that level again, temporarily masking your symptoms. Laura Veach, a researcher at Wake Forest Baptist Medical Center, puts it simply: “It doesn’t cure the hangover; it just sort of tricks you by masking the symptoms. They’re going to show up eventually.” You’re delaying the inevitable while adding more toxic byproducts for your liver to process. Every drink that claims to be a hangover cure because it contains alcohol is just pushing the hangover to later in the day.
A Practical Recovery Plan
Start with water as soon as you wake up. Within the first hour, add something with electrolytes and sugar: a sports drink, coconut water, or diluted fruit juice all work. If nausea is significant, sip ginger tea with honey before trying anything else. If you normally drink coffee, have a cup alongside water, not instead of it. A glass of milk later in the morning, when your stomach has settled, provides long-lasting hydration that plain water can’t match.
There’s no single miracle drink. The most effective approach combines fluids, electrolytes, and some sugar, then gives your body the few hours it needs to finish clearing acetaldehyde and restoring its normal balance.
