Your body clears alcohol at a rate of roughly one standard drink per hour, and there’s no way to speed that up. What you can do is manage the symptoms, give your body what it needs to recover, and avoid the mistakes that make things worse. Most hangovers resolve within 24 hours, but the right choices can shorten the misery considerably.
Why You Feel So Terrible
The awful feeling after a night of heavy drinking comes from several things happening at once. As your liver breaks down alcohol, it produces a toxic byproduct called acetaldehyde. This compound triggers a cascade of effects: blood vessels widen (causing flushing and headaches), your heart rate climbs, your airways tighten slightly, and nausea kicks in. Acetaldehyde also stimulates the release of stress hormones from your adrenal glands, which is why you might feel jittery or anxious the morning after.
On top of that, alcohol is a diuretic. It causes your kidneys to flush out extra water, leaving you dehydrated. Your blood sugar drops because alcohol suppresses your liver’s ability to produce glucose. And the sleep you got was poor quality: alcohol pushes your brain into deep sleep early in the night but suppresses REM sleep (the restorative dreaming phase) and fragments your sleep in the second half. Studies show there’s no REM rebound later in the night to compensate, so you wake up cognitively foggy regardless of how many hours you were in bed.
Rehydrate, But Do It Right
Water is essential, but drinking it alone isn’t the whole answer. Alcohol’s diuretic effect flushes out fluid, and if you’ve been vomiting or had diarrhea, you’ve lost even more. Sip water steadily rather than chugging large amounts, which can upset an already irritated stomach. Adding an electrolyte drink or mixing a pinch of salt into water with a squeeze of citrus helps your body actually retain the fluid rather than just passing it through.
Coconut water, broth, or a sports drink all work. The goal is to replace both fluid and the minerals your body lost. Aim to drink at least a few glasses over the first couple of hours after waking, and keep sipping throughout the day.
Eat the Right Foods
Your blood sugar is likely low. Alcohol interferes with your liver’s ability to produce glucose, and if you skipped meals or danced for hours, your energy stores are depleted. Eating is one of the fastest ways to start feeling human again.
Go for bland, easy-to-digest foods: toast, bananas, rice, eggs, or oatmeal. Protein and fat are especially helpful because they stabilize blood sugar more effectively than simple carbs alone. Eggs also contain an amino acid that helps your body process acetaldehyde. If your stomach can handle it, a meal with some combination of carbs, protein, and fat is ideal.
There’s some early evidence that foods rich in zinc and a B vitamin called niacin (found in chicken, fish, peanuts, and whole grains) are associated with less severe hangovers. A study published in the Journal of Clinical Medicine found that people with higher dietary intake of these nutrients reported significantly milder symptoms, including less vomiting. The study was small, so the findings are preliminary, but these are nutritious foods worth eating regardless.
Avoid greasy, spicy, or highly acidic foods. Your stomach lining is already irritated. Beer and wine in particular are powerful stimulants of stomach acid, so if those were your drinks of choice, your gut is working overtime. Gentle foods give it a chance to calm down.
Choose Your Pain Reliever Carefully
For a pounding headache, ibuprofen or naproxen are your best options. These anti-inflammatory medications can help with headache and general achiness. Take them with food to reduce the risk of stomach irritation, since your stomach lining is already vulnerable.
Avoid acetaminophen (Tylenol). Your liver is busy processing alcohol and its byproducts, and acetaminophen adds a competing burden that can increase the risk of liver damage. This risk is especially pronounced in people who drink regularly. Even taking acetaminophen shortly after your body has cleared the alcohol can be problematic, so it’s best to skip it entirely on hangover days.
Rest and Let Your Body Catch Up
Sleep is one of the most effective hangover remedies, partly because your first night’s sleep was compromised. Alcohol delayed the onset of REM sleep, reduced the total amount of it, and caused more wake-ups in the second half of the night. A nap or simply going back to bed gives your brain the restorative sleep it missed. Even 60 to 90 minutes can make a noticeable difference in how sharp you feel.
If you can’t sleep, rest on the couch. Avoid intense exercise. Light movement like a short walk can improve circulation and mood, but anything strenuous will further dehydrate you and stress a body that’s already working hard to recover.
What Makes Hangovers Worse
Not all drinks are created equal. Darker alcoholic beverages like bourbon, brandy, red wine, and whiskey contain higher levels of compounds called congeners, including methanol. Your body metabolizes methanol into formaldehyde and formic acid, both highly toxic. Methanol lingers in your system until ethanol levels drop, so its effects hit right as your hangover begins. Studies consistently find that drinks high in congeners produce worse hangovers than clearer options like vodka and beer, even when the total alcohol consumed is the same.
The “hair of the dog” approach (drinking more alcohol the next morning) delays your hangover rather than curing it. It works temporarily because ethanol blocks methanol metabolism, but you’re simply postponing the inevitable while adding more toxins to the queue.
A Practical Recovery Timeline
Your liver processes about 7 grams of alcohol per hour, roughly equivalent to one standard drink. If you had eight drinks, expect your body to need about eight hours just to clear the alcohol, not counting the additional time to mop up the metabolic damage. There’s a three- to four-fold variability in how fast different people metabolize alcohol, influenced by genetics, body weight, sex, and how often you drink.
For a moderate hangover, you can expect to start feeling better within 12 hours if you hydrate, eat, rest, and manage your headache. A severe hangover from a long night of heavy drinking can linger up to 24 hours. Here’s a reasonable approach for the day after:
- First hour awake: Sip water or an electrolyte drink. Take ibuprofen with a small snack like toast or crackers.
- Within two hours: Eat a real meal with protein, carbs, and some fat. Eggs and toast, oatmeal with banana, or chicken soup all work well.
- Mid-morning to afternoon: Nap if you can. Continue drinking fluids. Avoid coffee if your stomach is upset, since caffeine is a mild diuretic and can increase acid production. If you tolerate it fine, a small cup is okay.
- Evening: Eat another balanced meal. Most people feel significantly better by dinner if they’ve stayed hydrated and rested.
What Doesn’t Actually Work
There is no proven hangover cure. IV drip services, activated charcoal, and most supplements marketed for hangovers lack strong evidence. Greasy breakfast food is a cultural ritual, not medicine, and can actually make nausea worse. Sweating it out in a sauna dehydrates you further. The fundamentals (water, food, rest, and time) remain the only reliable strategy.
