"Comfortable Sleep Even in Economy Class"... Trend Goes Viral
Experts Warn: "Could Lead to Pulmonary Embolism"
Overseas, a trend known as the "In-Flight Sleep Challenge," in which people curl up and sleep in airplane economy class seats, is spreading via social networking services (SNS). However, experts are warning that this practice not only poses health risks but also violates aviation safety regulations.
On December 26 (local time), international media outlets such as Fox News reported that such videos have recently been posted on TikTok and Instagram.
The challenge involves sitting in an airplane seat, pulling one's knees up toward the chest, and wrapping the seatbelt around both legs to secure the body while sleeping. Some users claim that this posture "recreates the feeling of curling up in bed, improving sleep quality," and introduce it as a secret to deep sleep.
These videos have quickly gone viral, racking up millions of views, and travelers who frequently take long-haul flights have responded that "you can sleep comfortably even in cramped economy class seats." Not only influencers but also ordinary passengers are sharing themselves mimicking this posture, solidifying it as a kind of challenge.
However, opinions among medical professionals and aviation safety experts are divided. They point out that maintaining a curled-up position with legs bent for an extended period can impede blood circulation in the lower body, increasing the risk of deep vein thrombosis-commonly known as "economy class syndrome." There is also the possibility that a blood clot could travel to the lungs, resulting in life-threatening pulmonary embolism.
Dr. Carole Lieberman, a psychiatrist, stated in an interview with Fox News that this is "a very dangerous trend that causes the legs to be extremely tense and twisted," adding, "You are creating an environment where blood clots can easily form." She also warned that pressing the legs against the abdomen can impair digestive function or put strain on the cardiovascular system, potentially causing arrhythmia.
Safety concerns have also been raised. Sara Nelson, president of the Association of Flight Attendants-CWA in the United States, emphasized, "Seatbelts must be worn low and tight across the waist, and this is a regulation, not a choice." She warned that "failure to comply with crew safety instructions may result in a fine of up to $35,000."
Former flight attendant Jacqueline Whitmore also advised, "This posture may violate in-flight etiquette," and added, "Even if you have no choice but to curl up, you should be careful not to inconvenience other passengers."
