Promotes Heart HealthOne of the amazing benefits of traveling is that it promotes physical activity, whether it is rushing through the airport, walking the streets of a foreign land, or climbing a mountain. Physical movement lowers blood pressure and the risk of heart disease and stroke.
Severe episodes (massive embolism) present with collapse, severe breathlessness, and central chest pain. Symptoms of VTE commonly develop during or immediately after a flight, often while still in the airport.
Air travel increases the risk of developing blood clots in the veins of the legs, which can then enter the bloodstream and block an artery in the lungs, a condition called pulmonary embolism. In some cases, the opening can allow the blood clot to enter the arteries of the brain, causing a stroke.
Blood clots can sometimes form in your legs during air travel because you are immobile for long periods of time, often sitting in cramped spaces with little leg room. The clinical term for this type of blood clot is deep vein thrombosis (DVT). The longer the flight, the more at risk you are for developing a clot.
The elderly are also at greater risk of deep vein thrombosis (DVT) on long-haul flights. Also known as economy class syndrome, DVT is a blood clot that forms in a vein deep in the body, usually in the lower leg or thigh. If the clot breaks free it can cause a serious problem in the lungs, called a pulmonary embolism.
