Alcohol on an airplane can be dangerous
Above the Clouds, One Craves Something. Even a Glass of Champagne or a Few Beers. It is common for people to do so. However, this can become a health risk, especially during long flights. The combination of alcohol and the low cabin pressure is problematic.
Starting a vacation with a glass of champagne or calming nerves before flying - alcohol is a common occurrence in airplanes. However, this can become a health risk, especially during long flights. The problematic aspect is the combination of alcohol and the low cabin pressure.
You may have noticed that alcohol affects you differently in the air. A glass of wine in the sky can feel like two or even three glasses on the ground. The air pressure conditions in an airplane cabin play a significant role. They can lead to a faster absorption of alcohol into the blood, intensifying its effects. Additionally, the low cabin pressure reduces oxygen saturation in the blood - the effects of alcohol are further intensified.
Another issue: dehydration. The air in airplane cabins is extremely dry, which already contributes to rapid dehydration of the body. Alcohol also contributes to dehydration and can worsen this effect. Dehydration can lead to symptoms such as headaches or fatigue.
Consequences for the Heart
According to a study published by the Institute for Aerospace and Space Medicine in June 2024, the combination of alcohol, sleep, and reduced pressure conditions in an airplane cabin during a long-haul flight reduces the oxygen level in the blood (to around 85 percent) and increases heart rate (to approximately 88 beats per minute during sleep). Sleep quality was also significantly reduced. This effect was observed in young and healthy individuals and represents a significant burden on the heart.
Another aspect: Alcohol can impair judgment and self-control. In the confined and stressful environment of an aircraft, this can quickly become a stress factor - for example, if passengers behave aggressively or uncooperatively after consuming alcohol. This can also pose serious safety risks - for example, in emergencies or turbulence.
Many airlines have guidelines regarding alcohol consumption on board. For instance, most airlines do not allow passengers to bring alcohol purchased outside the airport onto the plane.
During the journey, the dry air in the cabin can exacerbate alcohol's dehydrating effects, leading to symptoms like headaches or fatigue. Furthermore, the combination of alcohol and low cabin pressure can increase heart rate and reduce oxygen levels in the blood, posing potential health risks, especially for young and healthy individuals.
