Have you ever noticed your ankles swelling after a long flight, train, or bus journey? Sitting for hours without moving can cause fluid retention in your legs, making them feel heavy, tight, and puffy. In rare cases, swollen ankles may also be caused by blood clots called deep vein thrombosis (DVT). Understanding why fluid retention happens and how to prevent blood clots can help travellers stay comfortable and safe during long trips.
Why Your Legs Swell During Travel
When you sit for a long time, blood flow in your legs slows down. This can cause fluid to leak into the tissues, leading to swollen ankles and feet. Shoes and socks may feel tight, and your legs can feel heavy or uncomfortable. For most travellers, this type of fluid retention is harmless and goes away after moving around. Women, older adults, and people on long journeys are more likely to notice swelling.
When Swollen Ankles Could Be Serious
Sometimes, ankle swelling can be a sign of DVT, a blood clot in the deep veins of the leg. Watch for pain, warmth, redness, or swelling in one leg. Travellers at higher risk, such as those with previous clots or limited mobility, should consult a doctor before long journeys. Simple steps such as moving your legs, staying hydrated, and wearing compression socks can help reduce the risk.
