The best things for a hangover are water, electrolytes, sleep, food, and time. No single remedy eliminates a hangover entirely, but the right combination can shorten your misery and ease the worst symptoms. Hangover symptoms typically begin as your blood alcohol level drops toward zero and stem from a mix of dehydration, inflammation, poor sleep quality, and toxic byproducts your liver is still processing.
Why You Feel So Bad
Understanding what’s actually happening in your body helps explain why certain remedies work. After a night of heavy drinking, your body ramps up production of inflammatory molecules, the same ones involved in illness and injury. Plasma levels of several inflammatory markers rise significantly, and their concentration directly correlates with how severe your hangover feels. This inflammation drives the headache, body aches, nausea, and general malaise.
Alcohol also disrupts your sleep in a specific pattern. In the first half of the night, it acts as a sedative, pushing you into deep sleep quickly. But in the second half, as your blood alcohol drops, a rebound effect kicks in: you spend more time in light sleep and wake up more often. The result is that even if you slept for eight hours, you missed out on the restorative phases your brain and body needed. That’s why you feel foggy, slow, and exhausted the next day even after what seemed like a full night’s rest.
On top of all this, alcohol is a diuretic. You lose fluids and electrolytes faster than normal, contributing to the thirst, dizziness, and dry mouth that define the morning after.
Hydration and Electrolytes
Water is the most straightforward fix. You’re dehydrated, and rehydrating addresses headache, dizziness, and dry mouth directly. But plain water alone doesn’t replace the sodium, potassium, and other electrolytes you lost. Sports drinks, coconut water, or oral rehydration solutions all work well here. Broth or soup serves double duty by providing both fluids and sodium.
Sipping steadily is more effective than chugging a large amount at once, especially if your stomach is already irritated. If you’re nauseous, small frequent sips of an electrolyte drink are easier to keep down than a full glass of water.
What to Eat
Eating helps, even if your stomach protests. Bland, easy-to-digest foods like toast, crackers, bananas, and rice settle your stomach while giving your body fuel to continue processing the remaining alcohol byproducts. Bananas are particularly useful because they’re rich in potassium, one of the key electrolytes depleted by alcohol.
Eggs are a popular hangover food for a reason beyond tradition. They’re rich in an amino acid called L-cysteine, which helps your liver neutralize acetaldehyde, the toxic compound your body produces as it breaks down alcohol. L-cysteine reduces cell damage and oxidative stress from acetaldehyde and supports the production of glutathione, your body’s primary detoxifying molecule. In supplement form, L-cysteine has been shown to relieve nausea, headache, fatigue, and anxiety after heavy drinking.
Fruit and fruit juice can also help. Fructose, the natural sugar in fruit, increases the rate at which your body clears alcohol from the blood compared to other sugars. In one study, fructose boosted alcohol clearance by roughly 30% over glucose. Honey, oranges, apples, and watermelon are all good sources.
Pain Relief: Choose Carefully
Reaching for a painkiller is instinctive, but the choice matters. Acetaminophen (Tylenol) and alcohol are both processed by your liver, and combining them raises the risk of liver damage. If you still have alcohol in your system or your liver is working hard to clear it, acetaminophen adds extra strain.
Ibuprofen (Advil, Motrin) or naproxen (Aleve) are anti-inflammatory drugs that can reduce hangover headache and body aches. There’s good reason for this: hangover symptoms are partly driven by elevated inflammatory markers, and these medications work by lowering those exact markers. However, they can irritate your stomach lining, which is already inflamed from the alcohol. Taking them with food helps, but if your stomach is very sensitive, it may be worth waiting until you’ve eaten something and rehydrated before taking a dose.
Sleep and Rest
Because alcohol wrecks your sleep architecture the night before, one of the most effective hangover remedies is simply more sleep. A nap gives your brain a chance at the restorative sleep it missed. Even 90 minutes, enough for one full sleep cycle, can noticeably improve the cognitive fog, irritability, and fatigue that linger through the day. If you can afford the time, sleeping in or napping is doing more for your recovery than most supplements or remedies.
What About Supplements and Herbal Remedies
Prickly pear cactus extract is one of the few herbal remedies tested in a controlled trial. In a study of 64 adults, taking the extract five hours before drinking reduced the risk of severe hangover by 50%. It specifically helped with nausea, loss of appetite, and dry mouth, though it didn’t improve headache, weakness, or dizziness. The catch is that you need to take it before drinking, not the morning after, which limits its usefulness if you didn’t plan ahead.
B vitamins and zinc have some evidence behind them as well, primarily because alcohol depletes both. A multivitamin or B-complex taken with food the morning after won’t hurt and may support your body’s recovery process. Ginger tea or ginger supplements can help settle nausea specifically.
What Doesn’t Work
“Hair of the dog,” or drinking more alcohol, delays your hangover rather than curing it. You’re simply restarting the cycle. Coffee can help with alertness and may ease a caffeine-withdrawal headache if you’re a regular coffee drinker, but it won’t speed up alcohol metabolism and can worsen dehydration if you don’t drink water alongside it.
Activated charcoal, IV drip bars, and most branded “hangover cure” supplements lack strong evidence. Your liver already has the machinery to process alcohol. The goal is to support that process with hydration, nutrients, and rest, not to try to bypass it.
Prevention Makes the Biggest Difference
What you drink matters almost as much as how much. Darker alcohols like bourbon, whiskey, and red wine contain higher levels of congeners, chemical byproducts of fermentation that worsen hangovers. Studies consistently show that bourbon produces more severe hangovers than vodka, which has very few congeners. Lighter-colored spirits and white wine tend to cause less intense morning-after symptoms at the same alcohol dose.
Eating a substantial meal before drinking slows alcohol absorption. Alternating alcoholic drinks with water throughout the night reduces total alcohol intake and keeps you hydrated. These simple strategies won’t make you immune to a hangover, but they can be the difference between a rough morning and a ruined day.
