Should you drink alcohol at high altitude? Here's what you should know

So, you’ve made it to a mountain lodge in Ladakh - India, the Alps - Switzerland, or the Andes - South America. The air is crisp, the view is jaw-dropping, and that glass of wine or whiskey by the fire is calling your name. But wait – should you actually drink alcohol at high altitude? While après-ski cocktails and summit champagne might sound romantic, your body’s reaction to booze up in the clouds can be trickier than you think. Let’s uncork the truth behind altitude and alcohol.

Alcohol + Altitude: A Double Whammy For Dehydration

Both alcohol and high altitudes are notorious for dehydrating the body. At elevations above 2,500 meters (8,200 feet), humidity drops, and you lose more fluids through respiration. Add alcohol’s diuretic effects, and you're basically sipping your way into a dehydration spiral.

What to Do:

  • Hydrate before, during, and after drinking.

  • Consider alternating alcoholic drinks with water.

You’ll Likely Feel Drunk – But You’re Not More Intoxicated

There's a long-standing myth that alcohol hits harder at high altitude. Technically, the alcohol content in your bloodstream (BAC) doesn't increase – but the symptoms might. Why? Lower oxygen levels can enhance the effects of alcohol like dizziness, fatigue, and impaired coordination.

Translation: You’re not drunk, you just feel like you are.

Alcohol Can Mask Symptoms Of Altitude Sickness

This is where things get serious. Acute Mountain Sickness (AMS) causes symptoms like headache, nausea, dizziness, and fatigue – all of which alcohol can either mimic or exacerbate. Even worse, drinking can dull your awareness of how badly altitude is affecting you.

Best Practice:

  • Avoid alcohol altogether in the first 24–48 hours at high elevation.

  • Let your body acclimate before reaching for that cold beer.

Sleep Quality Takes A Hit

You know how alcohol can mess with your sleep at sea level? Now picture it at altitude, where sleep is already harder to come by due to lower oxygen saturation. Drinking alcohol at elevation can further disrupt REM cycles, reduce breathing regularity, and leave you more fatigued the next day.

Tip: Save the nightcap for when you’re descending, not ascending.

Riskier Judgment In Riskier Terrain

Whether you're hiking up Machu Picchu or snowboarding in Zermatt, poor coordination and foggy judgment are not your friends at altitude. Alcohol can impair decision-making in situations where clarity is critical – not just for you, but for those around you.

Advice: Stick to celebratory toasts after your high-stakes activities.

Altitude Doesn’t Change Your BAC, But It Does Change Your Body

It’s important to note that while altitude doesn’t directly affect your BAC, physiological responses – like lowered oxygen saturation, increased heart rate, and slowed metabolism can make the experience of alcohol more intense.

Think of it as your body's way of saying: “Not now, buddy.”

But What If You Really Want to Sip Something?

If you're acclimatized, well-hydrated, and simply want to enjoy a drink with a view – go for it, mindfully. Opt for lower-ABV (alcohol by volume) drinks like beer or wine over hard liquor, and pace yourself.

Mountain Sipping Etiquette:

  • Choose quality over quantity.

  • Enjoy slowly and socially.

  • Never drink alone in remote areas.

Summing Up

In short, alcohol and high altitude don’t mix easily. While an occasional, mindful drink at elevation isn’t forbidden, it comes with caveats. Prioritize hydration, acclimatization, and common sense. If you're trekking, skiing, or climbing, delay that celebratory sip until you're safely back to a lower (or more stable) altitude.

Because let’s face it, no drink is worth altitude sickness, impaired judgment, or a sleepless night in a mountain hut.

Cheers (Responsibly), Even When You’re Up in the Clouds.
