The fastest way to feel better when you’re hungover is to rehydrate, eat something, get a pain reliever in your system, and rest. Most hangovers last about 12 hours after waking up, with symptoms peaking roughly 14 hours after your last drink. There’s no instant cure, but the right steps can take the edge off and help your body recover faster.
Why You Feel This Bad
Your body breaks alcohol down into a toxic byproduct called acetaldehyde before eventually converting it into harmless acetic acid. While that conversion is still happening, acetaldehyde circulates through your system and drives many of the symptoms you’re feeling: headache, nausea, fatigue, and general misery. Alcohol also triggers your body to release stress hormones and inflammatory compounds, which pile on top of everything else.
Dehydration is a major player too. Alcohol suppresses a hormone that tells your kidneys to hold onto water, so you urinate far more than you normally would. You lose electrolytes (sodium, potassium, chloride) every time that happens. On top of that, alcohol can cause your blood sugar to drop because it interferes with how your body manages glucose. Low blood sugar contributes to the shakiness, weakness, and brain fog.
Your sleep was also worse than you think. Alcohol disrupts the deeper, restorative phases of sleep, particularly REM sleep. Even if you were in bed for eight hours, you likely got far less quality rest than usual, which is why you feel exhausted despite technically sleeping.
Drink Fluids the Right Way
Water is the obvious first step, but how you drink matters. Sip slowly rather than chugging a full glass. Your body absorbs fluid more effectively in small, steady amounts. If you chug water on an already-irritated stomach, you may just trigger more nausea.
Electrolyte drinks can help because they contain a specific ratio of sugar and salt that pulls fluid into your bloodstream faster than water alone. Pedialyte, sports drinks, or even a pinch of salt in juice all work. That said, you don’t need to overdo it. Consuming excessive electrolytes can cause its own problems, including too much sodium in your blood. For most hangovers, alternating between water and an electrolyte drink is plenty.
Eat Something, Even If You Don’t Want To
Your blood sugar is likely low, and eating will help stabilize it. Bland, easy-to-digest foods are your friend here: toast, crackers, bananas, or oatmeal. Oatmeal is a particularly good choice because it’s gentle on your stomach and provides a solid dose of an amino acid called cysteine (about 227 mg per cup), which your liver uses to process alcohol’s toxic byproducts.
If you can handle something more substantial, eggs are a classic hangover food for good reason. They’re protein-rich and also contain cysteine. Broth-based soups work well too because they deliver both fluid and salt at the same time. The goal is to give your body fuel and nutrients without overwhelming your stomach.
Managing Your Headache Safely
You can take an over-the-counter pain reliever, but choose carefully. Ibuprofen (Advil, Motrin) or aspirin will help with headache and inflammation, though both can irritate an already-sensitive stomach. Take them with food if possible.
Avoid acetaminophen (Tylenol) when you’re hungover. The combination of acetaminophen and alcohol can cause serious liver damage. Your liver is already working overtime to clear the alcohol from your system, and acetaminophen adds a dangerous extra burden. This is one of the most important things to get right.
Dealing With Nausea
Ginger is one of the most reliable natural remedies for nausea, and it’s been used for hangovers since the Middle Ages. Ginger tea, ginger chews, or ginger ale (made with real ginger) can all settle your stomach. Studies on nausea relief have found that doses between 250 mg and 1 gram per day are effective, and going higher doesn’t seem to help more. A cup or two of strong ginger tea falls in that range.
If nausea is severe, avoid lying flat on your back. Sitting upright or propping yourself up with pillows helps keep stomach acid where it belongs. Small sips of clear fluids, taken frequently, are less likely to come back up than large gulps.
Should You Exercise?
The idea of “sweating it out” is appealing but misleading. Exercise doesn’t speed up how fast your body clears alcohol or its byproducts. That said, there’s some evidence that people who exercise vigorously as part of their regular routine experience less severe hangovers overall. The protective effect comes from consistent fitness habits, not from forcing yourself through a workout while miserable.
If you do feel up to moving, a light walk or gentle stretching is fine and may improve your mood. But don’t expect to perform well. Research confirms that hangovers impair physical performance, so it’s not the day for a hard run or heavy lifting. You’re also dehydrated, which makes intense exercise riskier than usual.
Sleep It Off (For Real This Time)
One of the most effective things you can do is go back to sleep. The sleep you got last night was fragmented and low-quality because alcohol shortened your time in REM sleep and caused more frequent wake-ups. A nap, even a short one, gives your brain a chance at the restorative sleep it missed. Keep the room cool and dark, and set an alarm if you’re worried about sleeping too long and throwing off your nighttime schedule.
The Recovery Timeline
Hangover symptoms typically start about 8 hours after your last drink and peak around 14 hours after, which for most people means the worst hits mid-morning. The full duration averages about 18 hours from your last drink, or roughly 12 hours after waking up. So if you wake up at 8 a.m. feeling terrible, expect gradual improvement through the afternoon, with most symptoms clearing by evening.
This timeline varies based on how much you drank, your body size, and what you were drinking. Darker spirits like brandy, rum, and red wine contain higher levels of compounds called congeners, chemical byproducts of fermentation that make hangovers worse. Brandy contains nearly 4,800 mg per liter of one congener (methanol), compared to just 27 mg per liter in beer. Vodka and lighter drinks tend to produce milder hangovers because your body doesn’t have to process as many of these extra compounds on top of the alcohol itself. One study found that bourbon, which is high in congeners, caused noticeably worse hangovers than vodka at the same alcohol dose.
What Doesn’t Work
“Hair of the dog,” or drinking more alcohol, delays your hangover rather than curing it. You’re simply resetting the clock and giving your body even more to process later. Coffee is a mixed bag: caffeine can help with headache and alertness, but it’s also a diuretic that may worsen dehydration, and it can further irritate your stomach. If you do drink coffee, keep it to one cup and drink water alongside it.
IV hydration services have become trendy, but for an ordinary hangover, they’re expensive overkill. Drinking fluids with electrolytes achieves the same rehydration for most people. Your body is well equipped to recover on its own once you give it water, food, rest, and time.
