Airline travel can cause foot swelling and potential risks associated with it
Long flights can take a toll on our physical well-being, and this is particularly true for our leg veins. According to a report published by Liter.kz, prolonged vertical positioning during long flights can lead to health challenges.
One of the key issues is venous stasis, a condition where blood flow in the lower legs slows down. This can cause vein dilation and increased venous pressure. Over time, this can increase the risk of deep vein thrombosis (DVT), where blood clots form in deep veins. These clots can potentially travel to the lungs, causing a life-threatening pulmonary embolism (PE).
The risks are heightened by factors such as cramped seating, reduced leg movement, low cabin humidity, dehydration, and lower oxygen levels in the airplane cabin. These conditions together slow venous return from the legs and promote clot formation.
People who are overweight, pregnant, smokers, have a history of clots, or certain health conditions are at higher risk.
Fortunately, there are steps passengers can take to mitigate these health issues. Wearing compression stockings can support venous return and reduce clot risk. Staying hydrated is crucial for maintaining blood volume and reducing blood viscosity. Taking regular breaks to stand and walk along the aisle can promote circulation, while doing in-seat leg exercises like foot flexes and leg raises can activate the "second heart," helping push blood back towards the heart.
Avoiding alcohol, sleeping pills, or excessive caffeine can also help, as these substances can contribute to dehydration and immobility. For those with known vein problems or risk factors, consulting a healthcare professional before flying is advisable.
The symptoms during long flights, such as feet feeling tight, ankles swelling, and legs feeling heavy, are often due to the disruption of water-electrolyte balance and the decreased function of the muscle-vened pump. The function of this pump may decrease during long flights, leading to venous stasis. This can result in edema, an increase in the volume of the foot, ankle, or distal part of the calf. However, edemas caused by long flights are usually temporary and disappear completely after a night's rest.
Dr. Vera Larina, a medical doctor, explains the health challenges posed by long flights, particularly for leg veins. By being aware of these risks and taking the necessary precautions, passengers can ensure a safer and more comfortable journey.
- To reduce the risk of health challenges during long flights, consider wearing compression stockings, as they can support venous return and decrease clot risk.
- Maintaining a hydrated lifestyle during a flight is crucial for keeping blood volume adequate and reducing blood viscosity.
- While traveling, incorporating frequent breaks to stand, walk, flex feet, and raise legs can promote circulation and activate the "second heart," helping with blood flow and reducing clot risk.
