Best food for a hangover: what to eat, what to skip and what your heart rate shows

Short answer

No food cures a hangover — time does. The US National Institute on Alcohol Abuse and Alcoholism (NIAAA) says there is "no cure for a hangover other than time", and a systematic review of randomized trials found "no compelling evidence" that any remedy prevents or treats one (1, 3).

What you eat can still make the day easier. The best food for a hangover is simple, gentle on the stomach and comes with fluid and salt: water, broth or soup, toast or crackers, rice or oatmeal, a banana, eggs if you can face them. MedlinePlus notes that sports drinks and bouillon soup help replace the salt and potassium lost through drinking (2). Most hangovers are gone within 24 hours, though symptoms can last longer (1, 2).

Your heart shows the night, too. In a study of 4,098 adults wearing heart monitors, sleep heart rate rose by about 1.4 beats per minute after a low dose of alcohol and by about 8.7 after a high dose, while HRV-based recovery dropped in step with the amount (4). If you feel wrecked the next morning, you're not imagining it, and it's not weakness: your body is still working.

Note: this article is for adults of legal drinking age (21+ in the US). It is general education, not medical advice, and it doesn't encourage drinking. Confusion, vomiting that won't stop, seizures, slow or irregular breathing, or someone who can't be woken up are signs of alcohol overdose: call 911 immediately and don't leave the person alone (5). Don't take acetaminophen (Tylenol) for a hangover: with alcohol it can harm the liver (1, 2). This guide is published by Welltory, which makes one of the apps mentioned.

Why you feel so bad the morning after

A hangover isn't one problem. It's several happening at once, and that's why no single food fixes it. The NIAAA lists the main causes (1):

• Fluid loss. Alcohol suppresses vasopressin, the hormone that tells your kidneys to hold on to water, so you lose more fluid than usual. Thirst, headache and a dry mouth follow.

• Broken sleep. Alcohol may help you fall asleep, but sleep later in the night becomes fragmented and you tend to wake early. That alone explains much of the fatigue.

• Stomach irritation. Alcohol irritates the stomach lining and increases acid, which is behind the nausea and stomach pain.

• Inflammation. Drinking raises inflammation in the body, which may add to the "flu-like" feeling.

• Acetaldehyde. Your liver turns alcohol into this short-lived, toxic byproduct before breaking it down further.

• A mini-withdrawal. As the alcohol wears off, the nervous system rebounds. Many people feel restless, shaky or anxious — the feeling often called "hangxiety".

• Congeners and sulfites. Compounds from fermentation, more common in darker drinks like bourbon, may make symptoms worse; sulfites in wine can cause headaches in sensitive people.

Symptoms usually peak as your blood alcohol level returns to about zero, which is why the worst hours are often mid-morning, not the moment you wake (1).

Food works on only some of these: fluid, salt, an irritated stomach and an empty tank. It can't speed up how fast your liver clears alcohol, and it can't give you back the sleep you lost. Keeping that in mind saves money on "miracle" products.

The best food for a hangover, by symptom

Think of hangover food as matching what your body is short of, not as a cure. Here's what tends to work, and why.

Based on the causes described by the NIAAA and the fluid advice from MedlinePlus (1, 2). The food choices are practical suggestions, not tested treatments.

Water, broth and soup

Fluid comes first. Small, frequent sips are easier to keep down than a big glass at once. If plain water feels hard, warm broth or a simple soup gives you fluid and salt together, and MedlinePlus specifically names bouillon soup as a good way to replace the salt and potassium alcohol washes out (2). Chicken noodle soup, miso soup or rice in broth all count.

Toast, crackers and other bland carbs

When your stomach is unsettled, plain starches are usually the easiest thing to keep down. Dry toast, saltine crackers, plain rice, pasta without a heavy sauce, oatmeal and a plain bagel all work. They don't neutralize alcohol, but they give you something gentle to eat when a full meal feels impossible.

Bananas

A banana is soft, easy on the stomach and a source of potassium, which you lose along with fluid. "Bananas for hangover" is a popular search for a reason: they're one of the few fruits most people can face on a rough morning. Pair one with toast or oatmeal for a gentle breakfast.

Eggs

Eggs are a hangover-breakfast classic. They're a simple source of protein, and scrambled or boiled eggs on toast are easy to make when you're tired. You'll often read that eggs "clear toxins" because they contain the amino acid cysteine; there isn't good human evidence that eating eggs speeds up recovery, so treat them as a good meal, not a remedy (3).

Oatmeal and whole grains

Oatmeal is warm, soft and filling without being heavy. Add a sliced banana or a little honey if you want it sweeter. MedlinePlus notes that fruit juice and honey are sometimes recommended for hangovers but that there is "very little scientific evidence" they help (2) — so enjoy them for taste, not as treatment.

Ginger and peppermint tea

Many people reach for ginger tea or peppermint tea when they feel sick. They're a pleasant way to get fluid in. We didn't find hangover-specific trials we could open and verify, so we won't promise they ease nausea; if they help you, that's reason enough.

What to drink for a hangover

Water is the base. Sip steadily through the morning rather than forcing a liter at once.

Sports drinks and oral rehydration drinks like Pedialyte add salt and sugar. MedlinePlus says electrolyte solutions such as sports drinks are good for replacing lost salt and potassium (2). The NIAAA adds an honest caveat: research hasn't shown that electrolyte drinks or IV "hangover drips" reduce how bad a hangover feels (1). So is Pedialyte good for a hangover? It's a reasonable way to rehydrate if you've vomited or sweated a lot, but it's not a cure, and plain water plus a salty snack does much of the same job.

Coffee won't cure a hangover (1). If you drink coffee every day, skipping it can add a caffeine withdrawal headache on top, so a normal cup is fine. Don't double it to "push through" — extra caffeine can worsen the jitters and the next night's sleep.

More alcohol — "hair of the dog" — may dull symptoms briefly but can drag the hangover out (1). It also delays your recovery and the next good night of sleep.

What not to eat or drink when you're hungover

• A greasy fry-up as a "cure". Does greasy food help a hangover? There's no evidence it does (3). Alcohol already irritates the stomach and raises acid (1), so a heavy, fatty meal can sit badly and worsen heartburn. If you want a diner breakfast, keep it modest and add toast and water.

• Very spicy or acidic food if your stomach is burning. Save the hot sauce for tomorrow.

• "Hangover cure" supplements and patches. The review in the BMJ found no compelling evidence for any conventional or complementary remedy; a few showed a small signal in single small trials that were never properly repeated (3).

• Acetaminophen (Tylenol). Combined with alcohol it can be toxic to the liver (1, 2). Aspirin and ibuprofen can irritate the stomach lining, so be cautious with them too and follow the label (1).

• Energy drinks. A lot of caffeine and sugar on top of poor sleep tends to make the afternoon crash worse.

A simple hangover breakfast and day plan

You don't need a special menu. A gentle, structured day does more than any single "superfood".

1. On waking: a glass of water, sipped slowly. If you feel sick, start with a few sips every few minutes.

2. Within an hour: something bland — toast, crackers or a banana.

3. Breakfast: eggs on toast, or oatmeal with banana, plus water or a sports drink. Your usual coffee if you're a daily drinker.

4. Mid-morning: more water. This is often when symptoms peak, as blood alcohol returns to zero (1).

5. Lunch: soup with rice or noodles, or a simple sandwich.

6. Afternoon: a short walk outside if you feel up to it, and a nap if you need one. Skip hard training — your heart is still recovering (more on that below).

7. Dinner: a normal, balanced meal.

8. Evening: no alcohol, an early night, and a cool, dark bedroom. The next night of sleep is the real repair.

MedlinePlus also notes that alcohol's effects on performance can linger even when you feel fine (2). Don't drive or operate machinery while you might still have alcohol in your system, and don't plan anything that needs sharp judgment for the morning after.

What eating before and during drinking can — and can't — do

This guide is about the morning after, but people often ask whether what they ate the night before matters. The honest answer: drinking on an empty stomach tends to hit harder, and a meal makes the evening more comfortable, but food doesn't stop a hangover. The NIAAA is clear that the only sure way to avoid one is to drink in moderation or not at all (1). The total amount of alcohol matters most, not the order of drinks (1).

It helps to know what counts as one drink. In the US, a standard drink contains 14 grams of pure alcohol — about 0.6 fluid ounces (5). A large glass of wine or a strong cocktail can easily be two.

What your resting heart rate and HRV show the morning after

Here's the part a hangover-food list usually skips: your heart keeps a record of the night.

In a large real-world study, researchers in Finland followed 4,098 employees who wore chest heart monitors through normal life, comparing nights with and without alcohol in the same people (4). In the first three hours of sleep:

The effect showed up even at low intake, and it grew with each step up in dose (4). In plain terms: after drinking, your nervous system spends the night in a more "on" state instead of resting. That fits with what you feel — a racing heart in bed, waking at 4 a.m., and a tired, wired morning.

What this means for you:

• A higher morning pulse is expected after a night of drinking. On its own it doesn't tell you what's wrong, but it does show your body hasn't fully recovered.

• A lower HRV is expected too. One low reading isn't a diagnosis; the pattern over the next few days is more useful.

• Food and water help you feel better, but they don't reset these numbers. Your heart rate and HRV usually come back as you sleep well and don't drink again. How long that takes varies — we cover it in how long it takes your body to recover after drinking and in what alcohol does to your HRV, heart rate and sleep the next day.

If you track your resting heart rate, compare the morning after with your usual range rather than with a chart. A normal resting heart rate for adults is broadly 60 to 100 beats per minute (what's a normal resting heart rate); what matters here is how far you are above your own baseline, and how fast you return to it.

Common hangover food myths

• "Greasy food soaks up the alcohol." By the morning, the alcohol has mostly been absorbed and processed. Fat doesn't absorb what's left, and it can sit badly on an irritated stomach.

• "Coffee or a cold shower will fix it." Neither prevents nor cures a hangover (1).

• "Beer before liquor, never sicker." The amount of alcohol matters most, not the order (1).

• "An IV drip or electrolyte powder is a cure." There's no research showing they reduce hangover severity (1).

• "A hangover pill will stop it." No remedy has been shown to work in rigorous trials (3).

• "If I eat well, I'm fine to drive." Food doesn't change how quickly alcohol leaves your blood, and performance can stay impaired even when you feel normal (2).

Who should be extra careful

• People taking medicines. Many medicines interact with alcohol, and some pain relievers are risky after drinking. Ask your pharmacist what's safe for you.

• People with diabetes. Alcohol can affect blood sugar. Follow the plan you've agreed with your care team, and eat regular meals.

• People with heart rhythm problems. If you notice a racing or irregular pulse after drinking that doesn't settle, get it checked.

• People who get hangovers after only one or two drinks. That's worth noticing — and worth discussing with a doctor.

• Anyone who feels they need a drink to stop feeling bad. That's a sign to talk to someone, not to push through.

Living with hangovers: the questions people ask next

What should I eat for a hangover breakfast?

Something bland and filling with fluid on the side: eggs on toast, oatmeal with a banana, or toast with peanut butter, plus water or broth. If your stomach is upset, start with dry toast or crackers and work up to a full breakfast.

What should I eat after drinking, before bed?

If you're hungry, a small, simple snack and a glass of water — toast, a banana, yogurt. A heavy, late meal can disrupt sleep further. Food at this point won't prevent a hangover, but water and a calm bedtime routine can make the night less rough.

Why do I crave junk food when I'm hungover?

Poor sleep shifts appetite toward high-calorie, salty and sweet foods — your body is tired and looking for quick energy. It's normal. Try to have a proper breakfast first; the cravings often ease once you've eaten and had some water.

Why do I feel anxious the day after drinking?

As alcohol wears off, the nervous system rebounds, which can feel like restlessness or anxiety (1). We go deeper in hangxiety: anxiety after drinking.

Why am I still tired two days after drinking?

The broken sleep from the first night plus a higher heart rate and lower HRV can take more than a day to settle, especially after heavier drinking (4). If you're also sluggish after big holiday meals, why you feel tired after eating may help.

Before you blame yourself

Feeling awful the morning after a celebration doesn't make you weak or "bad at drinking". It's chemistry: lost fluid, an irritated stomach, a nervous system rebounding and a night of fragmented sleep.

Before you blame yourself, look at your data. If your resting heart rate is up and your HRV is down, that's the night showing on your body — the cause is visible, and so is the way back. Pick one lever for the next two weeks: for example, a glass of water between drinks and a hard stop two hours before bed, or alcohol-free weeknights. Then watch whether your morning numbers and your energy change. Small, specific changes tell you more than any hangover hack.

When to see a doctor

Call 911 immediately if someone shows signs of alcohol overdose: confusion or stupor, trouble staying conscious or can't be woken, vomiting, seizures, slow breathing (fewer than 8 breaths a minute) or long gaps between breaths, a slow heart rate, clammy skin, very low body temperature, or bluish or pale skin (5). Don't wait for every symptom. Don't leave the person alone, and don't rely on cold showers, coffee or walking — they don't reverse an overdose (5). If they're vomiting, help them lean forward; if they're lying down, roll them onto their side (5).

See a doctor soon if:

• you can't keep fluids down for many hours, or you see blood in vomit

• you have chest pain, a racing or irregular heartbeat that doesn't settle, or you feel faint

• symptoms last well beyond a day, or you get bad hangovers after small amounts

• you notice yellowing of the skin or eyes, or severe stomach pain

• you're worried about how much or how often you drink

How to bring this up with your doctor

What to ask, by name. "Could my medicines interact with alcohol?" "Would liver function tests make sense for me?" "Is my heart rate after drinking something to look into?"

What to bring. A rough, honest count of how many standard drinks you have in a typical week; a list of your medicines and supplements; any notes on your morning resting heart rate or palpitations after drinking.

What to say, out loud. "After even a couple of drinks, I feel [symptom] for [how long]. I'd like to understand why."

If you feel brushed off. Ask: "What would make this worth checking further?" And if you're worried about your drinking itself, you can ask your doctor directly for support — it's a normal part of their job.

How Welltory helps — and what it cannot do

The limits first. Welltory is a general wellness product, not a medical device. It doesn't diagnose or treat anything, it can't tell you whether you're safe to drive, and it doesn't make drinking safer. If you're worried about alcohol, talk to a doctor.

What it can do is help you see your own pattern after a night out:

A morning spot reading. You can take a short HRV and heart rate reading with your phone's camera and flash — a deliberate spot reading, not continuous monitoring. It doesn't work on Google Pixel phones (6). Measuring at the same time each morning, before coffee, makes readings comparable — see how to measure HRV without a wearable.

Data from a watch you already wear. Welltory's compatibility list marks Apple Watch and Samsung Watch for HRV measurements and activity tracking; Fitbit, Garmin, Oura and Pixel Watch are marked for activity tracking (7).

Notes on what happened. When Welltory spots a stress or recovery episode and asks "What happened?", you can add a tag such as "late night" or "drinks", or type or say it in your own words, so you can later see how those days compared (8).

A record to share. From the web app you can export your data as CSV to bring to a doctor (9).

How we made it

We based this guide on the NIAAA fact sheets on hangovers and on alcohol overdose, the MedlinePlus Medical Encyclopedia entry on hangover treatment, a systematic review of hangover remedies published in the BMJ, and a large real-world study of alcohol, heart rate and HRV during sleep. Search questions came from what people in the United States most often ask about hangover food and what to eat when hungover. For the product section, we checked every function against the Welltory Help Center on November 8, 2026.
