Hangover Recovery: What Actually Works
There is no hangover cure, only time and supportive care: NIAAA says symptoms fully resolve on their own, usually within about 24 hours, as your body clears alcohol and its byproducts. In the meantime, sip water and an electrolyte drink, eat a real meal to correct the blood sugar drop alcohol causes, sleep, and skip acetaminophen if you have had several drinks recently since combining the two raises the risk of liver damage. Hair of the dog and sweating it out do not work and can make things worse.
Know there is no shortcut cure Expect most symptoms to resolve within about 24 hours as your body clears alcohol and its byproducts
NIAAA states plainly that time is the only thing that fully resolves a hangover; treating it as a repair job you can rush is how people end up reaching for things that do not work.
Drink water and an electrolyte drink through the morning About 500ml on waking, then steady sips (not large volumes at once) over the next few hours; add an electrolyte drink if you are also nauseated or vomited
Alcohol suppresses vasopressin and increases urination, causing mild dehydration that contributes to thirst, headache and fatigue. This helps those specific symptoms; a 2024 review found overall hangover severity is largely independent of hydration status, so treat this as supportive, not a fix.
Eat something with protein and carbohydrate as soon as you can stomach it A normal meal-sized portion; go bland (toast, crackers, eggs, banana, broth) if nauseated, then eat normally once you can
Alcohol can drop blood sugar, which contributes to the shakiness, dizziness and fatigue of a hangover; eating addresses that directly.
Use ibuprofen with food, not acetaminophen, if you've had several drinks in the past day Standard label dose of ibuprofen taken with food; avoid acetaminophen (Tylenol) if you've had 3 or more drinks in the past 24 hours
Getting this choice wrong is the one real medication risk in a hangover, not a comfort preference.
Prioritize extra sleep, even a nap, once you're rehydrated and fed Sleep in if you can; a short nap later is fine if the night's sleep was fragmented
Drinking fragments the second half of the night's sleep even though you fall asleep fast, and fatigue is a core hangover symptom; extra sleep is one of the few things that directly restores it.
Skip 'hair of the dog' and sweating it out No more alcohol, and no intense workout or sauna until you're rehydrated and feel normal again
NIAAA warns another drink can temporarily mask symptoms while prolonging the underlying hangover. Alcohol is cleared by the liver over time, not through sweat, and exercising dehydrated and nauseated adds strain without speeding anything up.
Recognize the signs of alcohol poisoning and get emergency help Repeated vomiting, confusion, seizures, slow or irregular breathing (fewer than 8 breaths a minute), pale or bluish skin, low body temperature, or being unable to wake someone: these are medical emergencies. Call for help immediately; do not wait for it to pass.
Alcohol poisoning can be fatal and can look like 'just a bad hangover' early on; this is the one step where waiting is the wrong answer.
NIAAA is direct that there is no cure for a hangover other than time.
