Deep Vein Thrombosis in Air Travel:This condition involves the development of blood clots in the deep veins of the legs, often occurring during or shortly after long flights, particularly in economy class where space is limited, and leg movement is restricted. The primary cause is prolonged immobility, which leads to blood pooling in the legs and increases the likelihood of clot formation. Factors like the seatbelt sign and crowded aisles exacerbate the lack of movement.Additional risks include reduced oxygen pressure and dehydration. Cabin pressure changes can lower blood oxygen levels, and the dry cabin air contributes to dehydration. Consuming coffee, tea, and alcohol—known diuretics—further dehydrates passengers.This syndrome isn't exclusive to economy class. Regardless of seating class, all travelers are advised to stay hydrated and keep their legs active by walking when possible and regularly stretching their ankles, knees, and hips to reduce the risk. Deep vein thrombosis is a serious condition that can lead to severe health complications, including death.
