Last call for your airplane cocktail? Researchers are urging for restrictions on in-flight alcoholic beverages due to the potential harm they can cause to passengers’ heart health. A recent study published in the respiratory journal Thorax revealed that the combination of alcohol consumption and cabin pressure at cruising altitude can lead to negative effects on napping passengers’ hearts.
The study, conducted by researchers from the Institute of Aerospace Medicine in Germany, found that even in young and healthy individuals, alcohol consumption combined with the conditions of being on a plane can lower the amount of oxygen in the blood and raise heart rate for an extended period. This can pose a risk of health complications and medical emergencies, especially among older individuals and those with pre-existing medical conditions.
To investigate further, the researchers conducted tests on a group of 48 people between the ages of 18 and 40. Half of the participants napped in a sleep lab under normal conditions, while the other half slept in an altitude chamber designed to mimic the cabin pressure of a plane at cruising altitude. On different nights, both groups went to bed sober and on another night, they consumed alcohol before sleeping.
The researchers monitored each person’s heart rate, blood oxygen saturation levels, and sleep stages and efficiency. They discovered that alcohol consumption, combined with cabin pressure and sleep, resulted in lower heart rates and decreased oxygen levels in the bloodstream. Even young and healthy individuals experienced these effects at increased levels when the factors were combined.
The study authors emphasized that the combination of alcohol intake and sleeping under hypobaric conditions can put significant strain on the cardiac system. They also noted that individuals with cardiac or pulmonary diseases, as well as those with sleep apnea and respiratory issues, should abstain from drinking for 12 hours before and during their flight.
Based on their findings, the researchers suggested changing regulations to restrict access to alcoholic beverages on planes. They concluded that the consumption of alcohol on board is an underestimated health risk that can be easily avoided. They emphasized the importance of informing practitioners, passengers, and crew members about the potential risks and considering alterations to regulations regarding alcoholic beverages on airplanes.
In light of these findings, it is clear that indulging in alcoholic beverages during a flight may have more detrimental effects than previously thought. Not only can it lead to decreased oxygen levels in the blood and increased heart rate, but it can also exacerbate symptoms in individuals with existing cardiac or pulmonary conditions. Therefore, it is advisable for all passengers, regardless of age or health, to refrain from consuming alcohol while on board. By prioritizing passenger safety and well-being, airlines can contribute to a healthier and more comfortable travel experience for everyone.
