As elevation will increase, air strain decreases, which means much less oxygen enters your physique with every breath. For most individuals it is just briefly uncomfortable however, in excessive instances, extreme mountain illness may very well be deadly.
It sounds ugly, however Paul Nicolazzo, the president of the Wilderness Medication Coaching Middle, stated: “There’s actually no motive to be afraid of going to excessive altitudes, so long as you perceive what you are coping with and obey some very guidelines. very fundamental.”
Know the signs
Mountain illness has 4 common signs: headache, gastrointestinal discomfort (nausea and lack of urge for food), fatigue/weak spot and dizziness/vertigo.
Many individuals get a morning headache from the altitude, when “your cranium feels too small for the pounding,” stated Steve Home, founding father of Uphill Athlete, an organization that gives endurance coaching. at excessive altitudes.
Additionally it is frequent to have issues sleeping at excessive altitudes. This occurs partially as a result of the a part of your nervous system accountable for maintaining you awake has come into play to boost your respiration price, Nicolazzo stated.
Take note of elevation
The 2 major elements of mountain illness are how excessive you go and how briskly you get there. Individuals with larger peak sensitivity would possibly begin to really feel uncomfortable round 1,524 meters above sea degree, which is the peak of locations like Denver and Johannesburg. In keeping with the Facilities for Illness Management and Prevention, anybody who travels above 8,000 ft above sea degree could also be prone to altitude illness.
Actual adventurers—like, say, those that climb the Himalayas or Mount Kilimanjaro—usually know that they’re heading to excessive altitudes. However the elevation of locations like Mexico Metropolis (about 2,400 meters), the highest of Haleakala in Maui (3,000 meters), Cusco (about 3,500 meters), and even Santa Fe, New Mexico (2,100 meters) might come as a shock to Travellers. To know what to anticipate, examine the elevation of your vacation spot beforehand on Google Earth or the USGS Nationwide Map Viewer.
Hearken to your physique
When you’ve got a situation akin to coronary heart illness, coronary heart failure, hypertension, hypercholesterolemia, atrial fibrillation, lung illness, COPD, bronchial asthma, or sleep apnea, you need to begin paying shut consideration to how you are feeling even when you find yourself about 1,500 meters above sea degree. .
When you’ve got a pre-existing situation or have had problem with excessive altitudes earlier than—or in case you are going someplace above 3,000 meters in altitude—contemplate visiting a specialist that can assist you put together and advise you on the principle medicines. which are used to forestall mountain illness, akin to Diamox (acetazolamide) and dexamethasone.
Enhance elevation whereas sleeping
Touring to excessive altitudes is a bit like operating a marathon: you may do higher should you take it little by little.
For example you are going snowboarding at a resort that is at a excessive altitude. Take into account step by step sleeping at the next altitude, because the important issue—for altitude functions—is the place you’ll spend the evening.
In case you’re touring from sea degree to Breckenridge, a Colorado ski resort at about 9,000 ft, spend an evening in Denver first, at 5,000 ft, stated Peter Hackett, founding father of the Denali Medical Analysis Mission and an altitude specialist. By doing so, he defined, “the incidence of headache is nearly halved. In order that little further time it takes to get to 2,700 meters to sleep generally is a large assist.”
Do not eat that greasy steak
Nicolazzo recalled that when he labored as a ski patroller, he would see conduct so frequent—and one which undoubtedly worsens mountain illness—that native cabins would put up warnings about it. There have been individuals who traveled from sea degree, drove to the ski areas close to Taos, New Mexico (which is about 7,000 ft above sea degree), “ate a steak, a baked potato with bitter cream and many butter,” and one or one other cocktail. Then the subsequent day they felt horrible.
To stop that from occurring to you, swap the steak and additional butter for extra carbohydrates, since fat and proteins require extra oxygen out of your physique to metabolize.
And if you are going to have a cocktail, make it only one: Alcohol and different depressants can decrease your oxygen degree, particularly whereas sleeping, Hackett stated.
Above all, drink loads of water. Staying hydrated will assist your kidneys work higher, Nicolazzo defined, which can assist you acclimate to the altitude and hopefully keep away from a headache.

On the extra extreme finish of the spectrum, if left untreated, mountain illness can result in high-altitude pulmonary edema, through which fluid builds up within the lungs, or, extra not often, high-altitude cerebral edema, through which fluid accumulates within the mind. Each circumstances will be deadly.
“There are three cures for mountain illness: go down, go down, go down,” Home stated. Anybody who seems disoriented or seems to have problem respiration or strolling — signs of great diseases akin to high-altitude pulmonary or cerebral edema — ought to come down instantly, Hackett stated. “Simply taking place a couple of thousand meters is what they want. And that may save your life.”
