Long-distance travel boosts blood clot risk

A new study suggests that traveling long journeys may significantly increase the risk of developing potentially life-threatening blood clots. Scientists now say long-distance journeys can triple the chances of getting a leg clot. The analysis shows the risk rises the longer the trip -- 18 percent higher risk for every 2 hours of travel, and 26 percent higher risk for every 2 hours of airplane travel.

Researchers suggest drinking lots of water and frequently moving around while traveling long distances can help reduce the risk of blood clots.

The study appears in the Annals of Internal Medicine.
