RiskThe risk of air travel thrombosis is just beginning to be understood. Gianni Belcaro's LONFLIT studies are finding that 3% of air travelers on long flights (10 hours or more) develop clots. Among frequent business travelers, LONFLIT IV found 4.5% developing one or more clots per year, about fifty times as many clots as found in a non-flying population. Most of these clots dissolve naturally, but the few that don't are still a huge public health problem. Some people are more likely to develop injurious clots than others. In the following pages, we discuss: - Risk Factors - Pilots - Athletes - Common misconceptions. Avoid:- Wearing anything that can restrict circulation, like a knee brace. - Crossing legs for more than a few minutes. - Sleeping, especially if you have any risk factors such as athletic training. If sleep is unavoidable, try to find a place where you can lie horizontal and/or arrange for someone to wake you after a short nap. - Alcohol, caffeine, and water. (See Hydration page.) |
