A few beers or cocktails after a long day on the slopes are a near necessity for many people’s ski vacations. But anyone who’s traveled from sea level to a mountain town like Breckenridge may have noticed that the alcohol seems to hit differently at elevation. Even a relatively normal night of drinking can leave someone feeling particularly rough the following morning. You’ve maybe even heard the claim that alcohol affects you more at altitude, but is that actually true or is it just another mountain myth?
Does Alcohol Actually Hit Harder at Altitude?
There are some conflicting claims about how elevation affects alcohol consumption. Research dating back to the 1930s suggested that two or three drinks at high altitude could have the same effects as four or five drinks at sea level. However,subsequent Federal Aviation Administration experiments reportedly found no correlation between elevation and alcohol potency.
That doesn’t mean drinking at altitude feels exactly the same. A 2026 review published in Signal Transduction and Targeted Therapy, titled Altitude Hypoxia and Hypoxemia, explains how higher elevations reduce oxygen availability and trigger physiological responses as the body attempts to acclimatize.
Alcohol doesn’t become chemically stronger at elevation. Instead the combination of reduced oxygen availability, dehydration, and overlapping symptoms can make its effects feel more pronounced.
Why Your Hangover Might Feel Worse in the Mountains
One major factor is that altitude sickness and alcohol consumption can produce similar symptoms. Acute mountain sickness can cause headaches, fatigue, nausea, and vomiting. These are also familiar symptoms of a hangover. The Center for Disease Control recommends avoiding alcohol and heavy exercise for the first 48 hours after you arrive at an elevation above 8,000 feet.
The overlap in symptoms can make a morning after drinking particularly unpleasant and potentially make it harder to recognize altitude sickness. Dehydration is another consideration. The California Department of Alcoholic Beverage Control explains that alcohol depletes bodily fluids and increases thirst, while altitude-related changes in breathing and fluid balance can also contribute to dehydration.
All of these factors can make recovering from a night of drinking feel especially difficult.
How to Avoid a Miserable Morning After Après-Ski
If you’re headed out on a high-altitude ski trip, it’s probably a good idea to take it easy with the après for the first few nights. Skiing can be a truly miserable experience if you’re fighting a brutal hangover, and you don’t want to be the person who misses several days of skiing because the booze hit you too hard.
Ultimately the science doesn’t support every popular claim about alcohol and elevation. Your beer doesn’t magically become stronger because you’re drinking it at 10,000 feet. But there are legitimate reasons to be more cautious with alcohol during a ski trip, particularly before your body has acclimatized.
