Once that “fasten your seatbelt” sign goes off, be sure to get up and move around to prevent deep-vein thrombosis (DVT), the formation of blood clots in your legs that can result from sitting immobile for long periods. (DVT can be life-threatening if a clot breaks off and travels to the lungs.)
To avoid it, move around the cabin every 60 to 90 minutes. And if you tend to get clots, talk with your doctor about support hose.
