A pounding headache, dry mouth, nausea, fatigue, dizziness, and the sudden conviction that last night’s final drink was a terrible idea: hangovers can make even a quiet morning feel difficult.

Unfortunately, there is no instant cure for a hangover. Your body needs time to process the effects of alcohol and recover. However, several practical steps can ease symptoms and make the recovery period more manageable.

Why Do Hangovers Happen?

A hangover is caused by several effects of drinking alcohol rather than one single problem. Alcohol can increase urination and contribute to dehydration, irritate the stomach, disrupt sleep, affect blood sugar regulation, promote inflammation, and expose the body to acetaldehyde as alcohol is metabolized.

These effects can combine to produce familiar symptoms such as:

• Headache
• Thirst and dry mouth
• Nausea or vomiting
• Fatigue and weakness
• Dizziness
• Sensitivity to light or sound
• Difficulty concentrating
• Irritability or anxiety
• Poor-quality sleep

The severity of a hangover varies depending on how much and how quickly you drank, whether you ate, your sleep, individual biology, and other factors.

1. Give Your Body Time

The most important fact about hangovers is also the least exciting: time is the only reliable cure.

Coffee, cold showers, supplements, greasy breakfasts, and other popular remedies cannot make your body eliminate alcohol instantly. Most hangovers improve over the course of the day, although symptoms can sometimes last 24 hours or longer.

Rest, avoid strenuous activity if you feel dizzy or weak, and allow yourself time to recover.

2. Rehydrate Gradually

Alcohol can contribute to fluid loss, so drinking fluids may help with thirst, dry mouth, and some dehydration-related symptoms.

Water is perfectly reasonable. If you have been vomiting or are significantly dehydrated, an oral rehydration solution or a drink containing electrolytes may also be useful.

Rather than forcing yourself to drink a large amount at once, take small, regular sips, particularly if your stomach feels unsettled.

3. Eat Something You Can Tolerate

You do not need an enormous greasy breakfast to recover.

If you feel nauseated, start with relatively bland, easy-to-digest foods such as toast, crackers, rice, bananas, oatmeal, soup, or other foods that normally sit well with you. Once your appetite returns, a balanced meal containing carbohydrates, protein, and nutritious whole foods can help you get back to your normal routine.

If you are vomiting, prioritize small amounts of fluid before trying to eat a substantial meal.

4. Get Some Rest

Alcohol can make you sleepy, but it can also disrupt normal sleep patterns and reduce sleep quality. That is one reason you may wake up exhausted despite spending plenty of time in bed.

If possible, keep your recovery day relatively light. Additional sleep or quiet rest may help while your body recovers.

Most importantly, do not drive or perform potentially dangerous tasks if you might still be impaired. Feeling awake is not the same thing as being sober.

5. Be Careful With Painkillers

Medication deserves more caution than many hangover guides suggest.

Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, may relieve headaches and muscle aches for some people, but they can also irritate the stomach and carry other risks. They may be inappropriate if you have certain medical conditions, take particular medications, are dehydrated, or have significant stomach problems.

Acetaminophen (paracetamol) also requires caution because both alcohol and acetaminophen involve the liver. Avoid casually combining medications with alcohol, and follow medication labels or advice from a healthcare professional.

6. Don’t Rely on More Alcohol

The traditional “hair of the dog” approach may temporarily change how you feel, but drinking more alcohol does not cure the underlying hangover.

At best, it postpones recovery. At worst, it encourages additional drinking and increases the risks associated with alcohol.

Once a hangover has arrived, the better approach is to stop drinking and let your body recover.

7. Coffee Can Help, but It Isn’t a Cure

If you regularly consume caffeine, a moderate amount of coffee or tea may make you feel more alert and can prevent a caffeine-withdrawal headache.

However, caffeine does not sober you up or eliminate a hangover. Large amounts can also make some people feel jittery, anxious, or more uncomfortable.

Stick to an amount you normally tolerate rather than trying to counteract alcohol with excessive caffeine.

Hangover Remedies That Are Mostly Hype

There is no shortage of supposed miracle treatments: detox drinks, special supplements, vitamin megadoses, raw eggs, greasy meals, cold showers, and various “hangover cure” products.

Some things may make an individual symptom feel better, but that is different from curing a hangover. Be skeptical of anything claiming to rapidly remove alcohol or toxins from your body.

Your liver does most of that work, and it needs time.

What About Exercise?

A hard workout is not a shortcut to sobriety. You cannot simply “sweat out” a significant amount of alcohol.

If you are dehydrated, dizzy, nauseated, or still impaired, strenuous exercise can make matters worse. Once you are feeling substantially better, gentle movement such as a short walk may feel good, but exercise should not be treated as a hangover cure.

The Best Hangover Strategy Is Prevention

If you choose to drink alcohol, the most reliable way to reduce the chance of a severe hangover is to drink less.

Eating before or while drinking, slowing your pace, alternating alcoholic drinks with non-alcoholic beverages, and stopping earlier can also help you avoid a miserable morning. Drinking water may reduce dehydration, but it does not cancel out the effects of consuming too much alcohol.

There is also no guaranteed amount of alcohol that will leave everyone hangover-free. Individual responses vary considerably.

When a “Hangover” May Be an Emergency

Not every severe reaction after drinking should be treated as an ordinary hangover. Alcohol poisoning can be life-threatening.

Seek emergency medical help if someone who has been drinking is difficult or impossible to wake, has trouble breathing or breathes unusually slowly or irregularly, has a seizure, repeatedly vomits while severely impaired, becomes severely confused, or develops pale, bluish, grayish, or clammy skin.

Do not assume an unconscious person simply needs to “sleep it off,” and do not leave them alone.

The Bottom Line

There is no magic hangover cure. The most useful approach is straightforward: stop drinking alcohol, hydrate gradually, eat when you can, rest, and give your body time to recover.

Be cautious with medications and skeptical of products promising instant results. If symptoms seem unusually severe or you are concerned about alcohol poisoning, seek medical attention rather than treating the situation as a routine hangover.

And if hangovers are becoming frequent, the most effective long-term remedy is not finding a better morning-after cure. It is reducing how much or how often you drink.
