When you take a long trip, you want to get up and stretch your legs, right? Besides keeping you from feeling stiff and sore, this simple act can also lower your risk of having a blood clot, a potentially dangerous health problem.\nBlood clots and travel can be linked, especially if you have certain risk factors. By learning some basic facts and tips, you can make sure you stay healthy and keep your risk of blood clots low.\nWhat Is a Blood Clot?\nBlood clots form normally when you injure a blood vessel, like from a cut or bruise. To keep you from losing too much blood, small pieces of cells, called platelets, stick together to form a clot. Once you have healed, your blood clot usually dissolves on its own.\nClotting helps your body heal itself, but some medical conditions, behaviors, and situations can cause dangerous blood clots to form. This can be life-threatening if a clot moves and blocks blood flow to your brain, heart, or lungs.\nTravel and Blood Clot Risks\nTrips of four hours or more \u2014 whether they\u2019re by plane, boat, train, bus, or car \u2014 can raise your risk of having a blood clot.
