Travelers should think twice before having a glass of wine on a flight and then falling asleep. A recent study published in Thorax found that consuming alcohol before sleeping on a plane could lead to a drop in blood oxygen levels and an increase in heart rate. The air in the cabin of a plane already has less oxygen than normal, and alcohol can further reduce oxygen levels, along with sleep.
The study, conducted by the Department of Sleep and Human Factors Research at the German Aerospace Center, involved healthy adults sleeping in a sleep laboratory and a hypobaric altitude chamber that mimicked airplane conditions. The participants who consumed alcohol experienced a drop in blood oxygen levels, higher heart rates, and lower quality sleep.
Dr. Marc Siegel, a medical expert, emphasized that the combination of alcohol, sleep, and high altitudes can have negative effects on the body, especially the heart. It’s important to stay hydrated while flying, as alcohol is a diuretic and the dry cabin air can be dehydrating. Dr. David Campbell also warned against alcohol consumption before or during flights, especially for individuals with certain health conditions.
Dr. Adam Scioli suggested alternative ways to manage stress and reduce anxiety while flying, such as deep breathing and mindfulness. He also advised staying hydrated, eating a healthy meal, and managing stress during takeoff and landing to avoid cardiovascular issues.
Overall, it’s essential to be mindful of the potential risks of consuming alcohol before sleeping on a plane, as it can impact blood oxygen levels and heart rate. Taking precautions, staying hydrated, and finding alternative ways to manage stress can help mitigate these risks and ensure a safer and more comfortable flight experience.
