Here's what you can do to relieve, or even prevent, the common discomforts of air travel. Swollen legs is a condition almost every airline passenger experiences. It can manifest as puffiness around the ankles or an uncomfortable tautness, or even cramps, in your calves. When you move about, your leg muscles contract, promoting blood flow. Sitting still throughout a flight causes blood to pool in your veins, making it difficult for fluid to move from body tissue back into the vessels.
Experts suggest stretching before, during and after the trip.
Shift your weight from one foot to another. While seated, elevate your feet and rotate your ankles to keep blood circulation going. Change positions in your chair. Whether you are sitting or standing, squeeze your buttocks together and hold for five seconds, then release. Avoid salty snacks just prior to and during your flight.
