Quick Answer
Drinking alcohol at high elevations is generally not recommended, as it can exacerbate altitude sickness symptoms, impair acclimatization, and increase the risk of dehydration and other complications.
Altitude Sickness Prevention and Alcohol
Drinking alcohol at high elevations can lead to dehydration, as it acts as a diuretic, increasing urine production. This can be particularly problematic at elevations above 8,000 feet (2,438 meters), where the air pressure is lower and the risk of dehydration is higher. Drinking 1-2 liters of water per day may help mitigate this effect, but it is still not a substitute for proper acclimatization.
Symptoms of Alcohol-Exacerbated Altitude Sickness
Symptoms of altitude sickness can be exacerbated by drinking alcohol at high elevations, including headaches, nausea, fatigue, and dizziness. In severe cases, alcohol can also contribute to the development of high-altitude pulmonary edema (HAPE) or high-altitude cerebral edema (HACE), both of which can be life-threatening. Monitoring symptoms closely and seeking medical attention immediately if they worsen or appear suddenly is crucial.
Treating Altitude Sickness in the Field
If you or someone in your group is experiencing symptoms of altitude sickness, it is essential to descend to a lower elevation as quickly and safely as possible. In the meantime, you can try taking Diamox (acetazolamide), a medication that can help alleviate symptoms and aid acclimatization. However, Diamox should only be used under the guidance of a medical professional, as it can have side effects and interact with other medications.
