1. What is the Connection Between Flying and Deep Vein Thrombosis (DVT)?
Prolonged immobility and dehydration during flights can increase the risk of deep vein thrombosis (DVT). When you remain seated for extended periods, especially on long-haul flights, blood flow in your legs can slow down, potentially leading to the formation of blood clots. Dehydration, common in the dry environment of an airplane cabin, further contributes to this risk by making the blood thicker and more prone to clotting. This condition gained attention after reports of travelers developing DVT, often referred to as “economy class syndrome,” highlighting the need for preventive measures to maintain healthy blood circulation during air travel. According to the World Health Organization (WHO), prolonged sitting, whether on a plane, train, or car, can double the risk of DVT, emphasizing the importance of staying active and hydrated during long journeys.
1.1 Why Does Flying Increase DVT Risk?
Flying increases DVT risk due to several factors, including prolonged sitting, low cabin humidity, and decreased air pressure. Prolonged sitting restricts blood flow in the legs, while low cabin humidity leads to dehydration, thickening the blood. The reduced air pressure in the cabin can also affect blood circulation, further elevating the risk of clot formation. According to a study published in The Lancet, the risk of DVT increases with flight duration, with longer flights posing a greater threat.
1.2 What is Economy Class Syndrome?
Economy Class Syndrome refers to the increased risk of DVT associated with prolonged immobility in the cramped seating of economy class on flights. The term gained popularity due to reports of travelers developing blood clots after long-haul flights in economy class, where limited legroom restricts movement and contributes to poor circulation. It is important to note that DVT can occur regardless of the class of travel, and the primary risk factor is prolonged immobility. The Centers for Disease Control and Prevention (CDC) recommends regular movement, hydration, and compression socks to mitigate the risk of DVT during flights.
2. What are the Pros and Cons of Taking Aspirin Before Flying?
Taking aspirin before flying has potential benefits, such as reducing blood clot risk, but also involves risks like increased bleeding and stomach upset. Aspirin’s blood-thinning properties can help prevent clot formation during long periods of immobility.
