Heart Beat: Stock these for a long journey
Stock these for a long journey
Planning a long trip by plane, train, bus, or car? A pair of special support stockings that squeeze your legs might be a good travel companion.
Sitting still for long periods, especially in the cramped confines of an airplane or other vehicle, can cause blood to pool in the legs and feet. In addition to swelling your feet, sluggish blood flow back to the heart can cause small blood clots to form. Most of these go unnoticed, broken apart by the body's natural clot busters. In some people, though, they can plug a vein and block blood flow (this is called a deep-vein thrombosis), leading to leg pain. A clot that breaks away and travels to the lungs (a pulmonary embolism) is a potentially life-threatening medical emergency.
