Neue Studie verrät, warum man im Flugzeug niemals Alkohol trinken sollte

For many holidaymakers, it is natural to start the summer with a few drinks. Whether you are already on the plane or have just arrived at your destination, a drink is often part of the ritual. After a few drinks at altitude, lean back in the plane and dream in a slightly tipsy sleepiness, it seems like the holiday has already begun.

However, recent research has shown that this common holiday behavior could be detrimental to your health. Experts are now advising you to rethink your in-flight drinking habits.

The effect of alcohol and low cabin pressure

Researchers in Germany have found that the combination of alcohol and the low cabin pressure at high altitudes can be a dangerous mix for your heart. The study, published June 3 in the journal Thorax, shows that blood oxygen levels drop and heart rates increase when passengers fall asleep after a few drinks.

The study, conducted by the Institute of Aerospace Medicine, examined 48 people between the ages of 18 and 40 over two nights to understand the effects of alcohol on a flight. Participants were tested in a sleep lab and a pressure chamber, with some consuming alcohol before bed.

Health risks of alcohol at altitude

The results show that alcohol combined with low cabin pressure leads to a drop in oxygen levels and an increase in heart rate, suggesting an underestimated health risk that can easily be avoided by drinking less during the flight.

The researchers recommend reviewing the rules for alcohol consumption on board. The combination of low oxygen concentration at high altitude and alcohol can affect sleep quality. It can also put a strain on the cardiovascular system and lead to low oxygen levels in the long term.

Recommendations for health-conscious travel

The authors of the study emphasize that even young and healthy people are significantly affected by alcohol consumption under hypobaric conditions. This can be particularly problematic for people with existing heart or lung diseases.

Dr. Elmenhorst, one of the researchers, says: „We were surprised by the strong effects. It is recommended not to drink alcohol during a flight. During sleep, oxygen saturation drops significantly, which can lead to a deterioration in health.“

Although young and healthy holidaymakers may not have serious heart problems, the increased heart rate and reduced oxygen saturation can aggravate existing medical conditions, so it is advisable to limit alcohol consumption during your flight to avoid unnecessary risks.
