Brits getting on planes this summer have been urged to spend £2.60 to avoid a common in-flight issue. Mobility experts are urging travellers to reconsider one seemingly harmless habit that could pose serious health risks on long journeys.
Lee Cartwright, mobility expert at Mobility Solutions Direct, says crossing your legs while seated on an aircraft can significantly reduce blood circulation, increasing the risk of developing deep vein thrombosis (DVT) – a potentially life-threatening condition caused by blood clots forming in the deep veins of the leg.
“Crossing your legs during a flight might seem harmless, but it’s actually one of the worst things you can do for your health while travelling,” said Lee Cartwright. “When you remain in the same position for several hours, particularly with your legs crossed, blood flow is restricted, placing additional strain on your circulatory system.”
Deep vein thrombosis most commonly develops in the legs and can become extremely dangerous if a clot breaks away and travels to the lungs, causing a pulmonary embolism. While DVT can affect anyone, older travellers are particularly vulnerable.

“As we age, our circulation tends to slow, muscle strength declines and the valves inside our veins become less effective at returning blood to the heart,” Cartwright explained.
“Many older adults are also living with conditions such as diabetes or cardiovascular disease, both of which can further increase the likelihood of blood clots developing during long periods of inactivity.”
Long-haul flights lasting more than four hours are generally considered to carry a higher risk, but experts stress that even shorter flights can reduce circulation if passengers remain seated for extended periods.
Fortunately, preventing circulation problems while flying is relatively straightforward. Cartwright recommends keeping both feet flat on the floor rather than crossing the legs and moving regularly throughout the flight.
To help maintain healthy circulation, travellers are encouraged to stand up and walk along the aisle every hour when it is safe to do so. If leaving the seat isn’t possible, simple exercises can still help stimulate blood flow.
“Try flexing your feet, rotating your ankles or gently lifting your knees every 30 minutes,” Cartwright advised. “These small movements encourage circulation and can reduce stiffness during the flight.”
Remaining well hydrated is another important step, as dehydration can contribute to thicker blood and reduced circulation. Experts also recommend avoiding prolonged periods of immobility before and after flights, where possible.
For those with existing circulation problems or anyone considered at higher risk of DVT, wearing graduated compression socks may also provide additional support by promoting healthy blood flow and reducing swelling in the lower legs. These can be purchased online from £2.60 per pair.
Travellers should also be aware of the warning signs of deep vein thrombosis after flying. Symptoms can include throbbing pain in one leg, swelling, warmth around the affected area, red or darkened skin, or swollen veins that feel hard or tender to the touch.
Anyone experiencing these symptoms should seek prompt medical advice, particularly if accompanied by chest pain or difficulty breathing.
