The fastest way to feel better from a hangover is to rehydrate with electrolytes, eat something, and rest. There’s no instant cure, but several strategies can meaningfully shorten your misery and help your body recover. Hangover symptoms peak once your blood alcohol level drops back to zero and can last 24 hours or longer, so the sooner you start helping your body along, the better.
Why You Feel So Terrible
A hangover isn’t just dehydration, though that’s part of it. Your liver converts alcohol into a toxic byproduct that triggers inflammation throughout your body. Blood levels of inflammatory molecules rise in proportion to how much you drank, and higher levels of these molecules are directly linked to worse next-day symptoms. At the same time, alcohol suppresses your liver’s ability to release stored sugar into your bloodstream, which can leave you shaky, weak, and foggy for up to 12 hours after your last drink.
Then there’s the sleep problem. Alcohol sedates you initially, but as your body processes it overnight, your sleep becomes lighter and more fragmented, particularly in the second half of the night. The deep, restorative sleep stage responsible for memory and emotional processing gets cut short. That’s why you can sleep eight hours after drinking and still wake up feeling like you barely slept at all.
Rehydrate With More Than Just Water
Alcohol is a diuretic, meaning it pushes fluid out of your body faster than normal. You lose not just water but essential minerals like sodium, potassium, and magnesium along with it. Plain water helps, but if you were vomiting or sweating heavily, an electrolyte drink will rehydrate you more effectively because the sodium helps your body actually retain the fluid rather than just passing it through.
You don’t need anything fancy. A sports drink, an oral rehydration solution, or even broth will work. Sip steadily rather than chugging a huge amount at once, especially if your stomach is still unsettled. Coconut water is another solid option since it’s naturally high in potassium.
Eat Something, Even If You Don’t Want To
Your blood sugar is likely low. While your liver was busy processing alcohol overnight, it wasn’t doing its other job of releasing glucose into your bloodstream. This contributes to that weak, trembling, can’t-think-straight feeling. Eating brings your blood sugar back up and gives your body fuel to work with.
Go for bland, easy-to-digest foods if your stomach is sensitive. Toast, crackers, bananas, eggs, or oatmeal are all good choices. Bananas are particularly useful because they’re rich in potassium, one of the electrolytes you’ve lost. Eggs contain an amino acid that helps your liver process the toxic byproducts of alcohol. The key is simply getting calories in. Don’t wait until you feel hungry, because the low blood sugar itself is making you feel worse.
Take the Right Pain Reliever
If your head is pounding, ibuprofen or naproxen are your best options. These reduce the inflammation driving your headache and body aches. Take them with food to protect your stomach lining, which is already irritated from the alcohol.
Avoid acetaminophen (Tylenol) while your body is still processing alcohol. Your liver is already working overtime to break down alcohol’s toxic byproducts, and acetaminophen adds to that burden. Overdose of acetaminophen is the most common cause of acute liver failure, and the threshold for harm drops when your liver is stressed. Stick with ibuprofen-type pain relievers, and keep the dose moderate.
Go Back to Sleep If You Can
The fragmented sleep you got last night is a major reason you feel so rough. Alcohol disrupts communication between the brain chemicals that regulate sleep and wakefulness, leading to frequent awakenings you may not even remember. A nap lets your body get the restorative sleep it missed overnight. Even 20 to 90 minutes can noticeably improve your energy and mental clarity.
If you can’t sleep, at least rest. Your body is running an inflammatory response and clearing toxins simultaneously. Physical exertion won’t “sweat out” the hangover. It will just dehydrate you further and make your heart work harder while it’s already under stress.
What Actually Doesn’t Work
“Hair of the dog,” or drinking more alcohol the next morning, is one of the most persistent hangover myths. It does temporarily mask symptoms by putting alcohol back in your system, but it simply postpones the hangover rather than curing it. You’ll feel the same symptoms later, potentially worse, because you’ve given your body even more alcohol to process.
Coffee is a mixed bag. Caffeine can help with the headache and grogginess, but it’s also a diuretic, which works against your rehydration efforts. If you’re a regular coffee drinker and skipping it would give you a caffeine withdrawal headache on top of everything else, have a small cup alongside plenty of water. Just don’t rely on it as a fix.
Why Some Hangovers Are Worse Than Others
The type of alcohol you drank matters more than you might think. Darker drinks like whiskey, bourbon, red wine, and dark beer contain higher concentrations of chemical compounds called congeners, which are byproducts of fermentation. These congeners independently worsen hangover symptoms. One study found that bourbon, a high-congener liquor, produced significantly more severe hangovers than vodka, which contains very few congeners. If you’re planning ahead for next time, sticking to lighter-colored drinks can make a real difference.
How fast your body processes alcohol also plays a role. People whose livers convert alcohol quickly tend to have less severe hangovers, because less alcohol reaches the brain. This is partly genetic, which explains why some people seem to bounce back easily while others are flattened by the same amount.
A Small Supplement That May Help
Red ginseng has some of the better evidence behind it. In a randomized crossover study of 25 healthy men, those who took a red ginseng drink after consuming whiskey had significantly lower blood alcohol levels at 30, 45, and 60 minutes compared to placebo. They also reported less fatigue, fewer stomachaches, less thirst, and better concentration the next day. Their overall hangover symptom score was about 35% lower than the placebo group’s. This is a small study, but the results were consistent across multiple measures.
If you already have red ginseng on hand, it’s worth trying. But don’t count on any supplement as a magic bullet. The fundamentals of hydration, food, rest, and time will always do the heaviest lifting.
The Realistic Recovery Timeline
Most hangover symptoms peak right around the time your blood alcohol concentration hits zero, which for a heavy night of drinking is typically mid-morning the next day. From there, symptoms gradually ease over the next 12 to 24 hours, though some people feel “off” for longer. Cognitive effects like poor concentration and slow reaction times can linger even after the headache and nausea fade.
The honest truth is that time is the only thing that fully resolves a hangover. Everything else just helps you feel less miserable while your body does its work. Prioritize fluids, food, and rest, and give yourself permission to take it easy for the day.
