Millions of people fly every day, but not many know about a dangerous air travel-related health risk known as deep vein thrombosis (also known as DVT or “economy class syndrome”). The serious health condition, which happens when long periods of inactivity like flying lead to the formation of a blood clot in the leg, affects travelers of all ages — especially those who are on long-haul flights or long train and car trips that call for passengers to stay seated for several hours at a time.
Fortunately there are several ways to prevent DVT, including obvious things like wearing compression stockings and not so obvious things like drinking wine. For a full list of travel tips that can help reduce your risk of forming blood clots in your legs during long flights, as well as the typical symptoms of blood clots in the legs, click through the gallery above.
