Move Around on a Plane

When you're stuck in an airplane seat, your blood can pool in your feet, increasing the risk of developing a blood clot.

The American Council on Exercise suggests how to reduce your risk:

• If your flight is three hours or longer, take a walk through the cabin at least every 30 minutes when it's safe to do so.
• When sitting down, stretch your legs as much as possible.
• Make sure clothing fits loosely and comfortably.
• If you nap, don't sleep for longer than 30 minutes.
• Ask for water instead of caffeine or alcohol.
• If you have a layover, take a brisk walk through the airport.
