The 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
- Common misconceptions.
- 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.)
