What strategy could effectively reduce the risk of deep vein thrombosis during long air travel?

Staying hydrated during the flight and wearing compression stockings are both effective strategies for reducing the risk of deep vein thrombosis (DVT) during long air travel.

Hydration plays a crucial role in maintaining adequate blood volume and circulation. When traveling on long flights, individuals may become dehydrated due to the low humidity in the cabin environment, which can lead to thicker blood. Staying well-hydrated helps to ensure that blood flows more easily through the veins, minimizing the risk of clot formation.

Wearing compression stockings is another important measure. These stockings are designed to apply graduated pressure to the legs, which helps to promote venous return—the flow of blood back to the heart. By preventing blood from pooling in the lower extremities, compression stockings can significantly lower the risk of DVT formation.

In summary, combining adequate hydration with the use of compression stockings provides a comprehensive approach to minimize the risk of DVT during extended periods of immobility, such as long flights. This combination not only addresses the mechanical aspects of blood flow but also considers the physiological changes that can occur during air travel.
