Make Air Travel Safer: Walk

Read Transcript

You have your boarding pass and passport, but before you claim a seat in the waiting area take a walk. Hi, I'm Dr. Vanda Wright. Long flights, cramped seats and age are all risk factors for deep vein thrombosis or DVT. That's a blood clot in a deep vein. Now there's no proof that walking around prevents DVT but it can't hurt.

Neither can doing those anti-clotting plane seat exercises found in many in-flight magazines. And if you are over 40 and your flight time is longer than four hours you should stroll the plane isles every couple of hours. Why? When you're immobile blood flow slows and clots may form. That can cause scary problems if say a clot breaks loose and gets into your lungs. Here are other common sense tips before you board.

Take two baby aspirins with a glass of water before boarding to make your blood platelets less sticky and helps prevent clots. Drink water to stay hydrated. Skip alcohol if possible. Definitely don't have more than one. Wear compression stockings. And lastly relax, stress can encourage blood clots.
