Avoid high-salt foods
“Unhealthy foods packed with salt can cause constipation, which puts pressure on the venous system,” says Dr. Navarro. So as inviting as that Popeyes chicken or Chick-fil-A looks during your two-hour layover in Atlanta, maybe just opt for a salad.
Keep the area under your seat clear
So, you thought you’d be clever and pack two weeks’ worth of clothes into your “carry-on” and stuff that oversized bad boy in the overhead bin. But wait, now your “personal item” is full of books, computer gear, and stolen copies of SkyMall, and it’s taking up all the room under your seat. Which means no room to exercise your feet. Shell out the $25, check a bag, and save yourself the blood clots. Or, bring fewer copies of The Da Vinci Code.
