The Effects of Wine at High Altitudes

Many resorts at high altitudes offer wine as refreshment.

High altitudes can cause a number of health problems, including feelings of exhaustion, shortness of breath, headaches or heart palpitations. When wine, or any alcohol, is added into the equation with increased elevation, the probability of problems is drastically increased. It is widely recommended not to drink alcohol for the first 48 hours after traveling to altitudes of over 5,280 feet, or 1 mile.

Increased Rate of Absorption

Since there is less oxygen in the environment at high altitudes, the body begins to create more red blood cells to be able to absorb more oxygen. These extra red blood cells also absorb ingested chemicals at a rapid rate. Alcohol, blood thinners and barbiturates will have a magnified effect on the body. These effects are more pronounced for the first 48 hours. After the body adapts to the oxygen-starved environment, the rate of absorption will decrease.

Dehydration

High altitude is known to cause dehydration. Alcohol also causes dehydration. When you are drinking alcohol at high altitudes you are going to have both of these negative effects simultaneously. It is recommend to drink a glass of water for every glass of wine consumed at low elevations. At high elevations, make sure to space out a couple of glasses of water in between glasses of wine. This will allow the body to sufficiently hydrate itself.

Decreased Cognitive Performance

High altitude alone can decrease cognitive performance, until the body acclimates. A person will react slower and reason slower until the body starts absorbing enough oxygen. These are very similar to the regular effects of consuming alcohol. Combined together, high altitude and alcohol cause serious risks when driving a motor vehicle or operating heavy machinery. Unfortunately, the ability to realize these risks while under the influence is hampered. Make sure to have a sober driver or a taxi service ready when planning to drink at high altitudes.

Increased Chance of Altitude Sickness

There is an increased chance of altitude sickness when consuming alcohol. The symptoms of altitude sickness are severe headaches, dizziness, confusion, nausea, blue lips, vomiting, pressure in the chest, rapid breathing and increased heart rate. With the presence of any of these symptoms, medical attention should be sought immediately. If possible, oxygen should be administered through a mask or nasal catheter. The person with these symptoms should be encouraged to sit and relax and avoid any physical activities.
