About International Hangover Day
International Hangover Day is observed on the first Saturday of August each year, falling the day after International Beer Day, which is celebrated on the first Friday of August. In 2026, International Hangover Day falls on Sunday, 2 August. It is a lighthearted, tongue-in-cheek observance that acknowledges the morning-after consequences of celebrating International Beer Day with perhaps a little too much enthusiasm.
How to Celebrate International Hangover Day
Whether you’re genuinely nursing a hangover or simply enjoying the day off, here’s how to make the most of this gloriously low-key occasion:
- Drink plenty of water – Alcohol is a diuretic, meaning it causes the body to lose more water than it takes in. Rehydrating is the single most important step in hangover recovery. Aim for at least two litres throughout the day.
- Eat a restorative breakfast – A full cooked breakfast replenishes electrolytes and blood sugar. Eggs contain cysteine, which helps break down acetaldehyde, the toxic byproduct of alcohol metabolism. Toast provides simple carbohydrates for a quick energy boost.
- Try a sports drink – Sports drinks containing electrolytes (sodium, potassium, magnesium) can help restore the mineral balance disrupted by alcohol consumption more quickly than water alone.
- Rest and take it easy – International Hangover Day is not a day for ambition. Plan nothing more demanding than a gentle walk, a favourite film, and a long nap.
- Try a traditional hangover remedy – Every culture has its own hangover cure, from Japanese miso soup and Korean bean sprout soup to the British “Full English” and the Mexican michelada. Use the day to explore international hangover wisdom.
- Reflect on balance – Use the day humorously but also honestly to reflect on your relationship with alcohol. International Hangover Day is funny precisely because most people have been there, but it’s also a gentle nudge toward more mindful drinking in future.
- Support a friend – If someone you know had a big night, check in on them. Drop round with supplies, make tea, and sit with them through the suffering. Solidarity is the unofficial theme of the day.
- Share your hangover cure – Post your most reliable hangover remedy on social media and start a conversation about the universal experience of the morning after.
What is International Hangover Day?
International Hangover Day is a humorous annual observance that follows International Beer Day, celebrating (or commiserating about) the experience of a hangover with solidarity and good humour. It is not a medically endorsed event, but a culturally resonant one: almost every society that consumes alcohol has developed its own vocabulary, folklore, and remedies around the hangover, and the day acknowledges that shared human experience.

The History of International Hangover Day
International Hangover Day’s origins are tied directly to those of International Beer Day. International Beer Day was founded in Santa Cruz, California, in 2007 by Jesse Avshalomov, a beer enthusiast, with the intention of celebrating great beer, toasting to brewers and bar staff worldwide, and enjoying the shared pleasure of craft ales, lagers, and stouts. The first Friday of August was chosen for its association with the end of the working week and the start of the weekend.
It was essentially inevitable that the day after International Beer Day would become International Hangover Day. The connection is so logical that multiple independent sources are credited with formalising the idea, though no single founder is definitively recorded. The day gained considerable traction online in the 2010s, helped by the humour and shared recognition of anyone who has ever celebrated a little too enthusiastically. An alternative origin story credits a group of friends in Australia who first posted about a “Hangover Day” tradition as a humorous response to New Year’s Eve festivities, a tradition that was subsequently mapped onto the post-International Beer Day weekend.
National Hangover Day, the US domestic version, is observed on 1 January, making it one of the few occasions in the awareness calendar to be entirely self-explanatory in its timing.
Fun Facts About International Hangover Day
- The scientific term for a hangover is “veisalgia”, derived from the Norwegian “kveis” (uneasiness following debauchery) and the Greek “algia” (pain).
- A 2015 study in the journal Alcohol and Alcoholism found that the best predictor of hangover severity was not the type of alcohol consumed but the total amount of alcohol and whether any sleep was disrupted.
- The concept of a “hair of the dog” (drinking more alcohol to cure a hangover) has no scientific basis but persists in popular culture across many countries.
- International Beer Day was founded in Santa Cruz, California, in 2007 by Jesse Avshalomov, making International Hangover Day almost as old.
- Approximately 75% of people who drink to intoxication will experience at least mild hangover symptoms, according to researchers at the Alcohol Hangover Research Group.
- The economic cost of hangovers in the United States, in terms of lost workplace productivity, has been estimated at approximately USD 77 billion annually by the National Institutes of Health.
Why International Hangover Day Matters
International Hangover Day is, at its heart, a celebration of solidarity and shared human experience. Almost everyone who drinks has had a morning when they swore they’d never drink again, and there is comfort in knowing that experience is universal. The day also provides a gentle, humorous prompt toward more mindful drinking: if the day after is this unpleasant, perhaps the calibration of the night before needs some adjustment.
