A hangover peaks when your blood alcohol level drops back to zero, typically the morning after drinking, and symptoms can linger for 24 hours or longer. There’s no instant cure, but several strategies can shorten your misery by addressing the specific things alcohol does to your body: dehydration, inflammation, low blood sugar, and wrecked sleep. Here’s what actually helps and what to skip.
Why You Feel This Bad
A hangover isn’t just dehydration. When your liver breaks down alcohol, it produces a toxic byproduct that triggers the release of free radicals. Your immune system treats these byproducts as foreign invaders and mounts an inflammatory response, flooding your bloodstream with the same signaling molecules that make you feel awful when you have the flu. Studies measuring these inflammatory markers in hungover people found that the higher the levels, the worse the hangover. That’s why you feel achy, foggy, and generally sick all over, not just thirsty.
On top of that, alcohol suppresses your liver’s ability to produce glucose, which can leave your blood sugar abnormally low the next morning. It also wrecks your sleep architecture: you may fall asleep faster, but alcohol suppresses REM sleep and causes fragmented, shallow sleep in the second half of the night. So even if you were in bed for eight hours, your brain didn’t get the restorative rest it needed.
Rehydrate With More Than Water
Start drinking fluids as soon as you wake up. Plain water helps, but if you feel weak, dizzy, or faint, a drink with electrolytes (sodium, potassium, and a small amount of sugar) restores what you’ve lost more efficiently than water alone. Sports drinks, coconut water, or oral rehydration solutions all work. Sip steadily rather than chugging a liter at once, which can trigger nausea.
Eat Something, Even If You Don’t Want To
Your blood sugar is likely low because alcohol interfered with your liver’s normal glucose production overnight. Eating a meal with both carbohydrates and protein helps stabilize it. Toast, eggs, oatmeal, bananas, or a simple sandwich are all good options. You don’t need a greasy diner breakfast specifically, but you do need calories. If nausea makes eating hard, start with something bland like crackers or a piece of fruit and work up from there.
Choose the Right Pain Reliever
This is where people make a dangerous mistake. Acetaminophen (Tylenol) and alcohol are both processed by your liver, and combining them can cause severe liver injury. The FDA explicitly warns against drinking alcohol when taking acetaminophen, noting cases of acute liver failure, transplant, and death. Even the morning after heavy drinking, your liver is still under stress. Avoid acetaminophen entirely while recovering.
Ibuprofen (Advil, Motrin) is a safer choice for headache and body aches. Aspirin is another option, though endoscopic studies show aspirin causes considerably more damage to the stomach lining than ibuprofen does. Since alcohol already irritates your stomach, ibuprofen is generally the gentler pick. Take it with food to reduce any additional stomach irritation.
Go Back to Sleep If You Can
Alcohol causes your brain to skip the most restorative phases of sleep, particularly REM sleep. In the first half of the night, alcohol pushes you into deep sleep unusually fast. But in the second half, it causes frequent waking and light, fragmented sleep. The result is next-day fatigue, impaired focus, and emotional irritability that have as much to do with poor sleep quality as with the alcohol itself.
If your schedule allows it, a nap of 20 to 90 minutes can help your brain catch up on some of what it missed. Even resting quietly in a dark room gives your nervous system a break from the sensory overload that makes hangovers feel worse.
What About Supplements and Ginger?
Ginger tea or ginger chews can help settle nausea, and it’s one of the better-supported natural remedies for an upset stomach in general. A small randomized crossover study of 25 healthy men found that red ginseng helped lower blood alcohol levels and reduced hangover severity scores, though the research is still limited. Neither of these is a miracle cure, but ginger in particular is low-risk and worth trying if nausea is your main problem.
What Doesn’t Work
“Hair of the dog,” or drinking more alcohol the next morning, delays your hangover rather than curing it. It temporarily raises your blood alcohol level again, which masks symptoms, but the inflammation and metabolic disruption continue underneath. You’ll feel worse later.
Coffee can help with the headache if you’re a regular caffeine drinker (since skipping it causes withdrawal headaches on top of everything else), but it’s a diuretic and can worsen dehydration. If you drink coffee, match it with extra water.
Dark Liquor Makes It Worse
Not all drinks produce equal hangovers at the same alcohol dose. Dark spirits like bourbon, whiskey, and red wine contain higher levels of congeners, which are byproducts of fermentation that add flavor and color. Experimental studies comparing bourbon (high congeners) to vodka (essentially no congeners) found that bourbon produced more severe hangover ratings. That said, the amount of alcohol you drink still matters far more than the type. Vodka in large enough quantities will still leave you miserable.
A Realistic Recovery Timeline
Most hangovers follow a predictable arc. Symptoms are worst in the morning when your blood alcohol hits zero, then gradually improve over the course of the day. Mild hangovers from a few extra drinks often clear up by the afternoon. Heavy drinking can produce symptoms that last a full 24 hours or longer, with fatigue and brain fog being the last to resolve since your sleep deficit takes more than one good night to fully recover from.
The most effective recovery strategy is also the simplest: fluids with electrolytes, food with carbs and protein, ibuprofen if you need it, and as much rest as you can manage. Your body is running an inflammatory response and trying to restore normal blood sugar and hydration at the same time. Give it the raw materials and the time to do that work.
