Long flights are tiring, especially finding a comfortable sitting position on the plane is a big challenge. The small seats and limited leg space make many passengers feel that "crossing their legs" to make themselves relax a little. However, physical therapist Bethany Tomlinson recently warned that this seemingly harmless posture may bring health concerns. According to a study from the UK, more than one-tenth of adults have questions about the issue, and sitting still on the plane for a long time will make these pains even worse. Tomlinson said that he would avoid tumbling his feet when taking the opportunity, "this will affect blood circulation and increase the risk of deep static embolism (DVT)."

Deep static embolism is a blood block caused by long-term sitting and may be life-threatening at severe times.

Tomlinson recommends that passengers keep their legs raised as much as possible during the flight, and change their seating position to maintain blood flow. If there is a foot pedal under the seat in front, it can be used to raise their legs slightly. Relax your shoulders when sitting and lean your back against the seat to help support your body and reduce pressure.

In addition to adjusting the sitting position, she also recommends that passengers spend some time standing and performing simple movements to reduce pressure when waiting or redirecting, and can shift the weight between the feet, slightly sway the knees, and do some simple stretching to avoid excessive pressure from the lower body.

For long flights, she recommends moving her body every 1 to 2 hours on the machine to prevent stiffness or dysfunction, especially the knees, ankles and hips. Simple seating exercises can be done during flights, such as leeward stretching, shoulder slimming, or knee-to-leg holding, etc. These actions can help promote blood circulation and reduce DVT risks.

"The correct sitting posture and simple serene movement during the flight are important for keeping the serene flexible." Tomlinson reminds that keeping physical activity during the flight is not crossing your legs, so as to give the serene and circulation system a healthy choice.
