Travel-Related Thrombosis: Risks and Tips
I came across this article on venous thrombosis, where blod clots form usually on the legs, and hamper circulation. It’s a condition commonly associated with long air travel, but recent data shows that no matter what mode of transportation you use– by car, train, or plane– you are increasing your risks of suffering from this condition particularly if you’re on the go for a long period of time (long = about 4 hours).
Of course, some people are more prone than others. I’ve travelled 12-14 hour flights and drives without any complaint, other than tiredness and a numbed backside. Apparently, there are factors that may increase risks of contracting travel-related thrombosis:
- a mutation in one of the genes involved with clotting, called factor V Leiden
- a body mass index of more than 30 kg/m2
- height of more than 1.90 m (although people shorter than 1.60 m had an increased risk of thrombosis after air travel)
- use of oral contraceptives
You may want to read the manuscript describing the results of the study in the Public Library of Science, or see the feature report from Times UK.
However, we cannot refrain from travelling just becasue there are risks associated with it. No way! Here are some tips how you can lessen your risks of developing travel-related thrombosis:
- Take frequent breaks during the journey if you can, and strech out your legs. If you’re “trapped” in a plane, you can get up every now and then, and walk back and forth along the aisle. Some airlines also offer inflight programs showing some exercises you can do even while sitting. Main point is, move!
- Wear loose clothing, particularly when travelling in cramped spaces and during air travel.
- Drink enough water to prevent dehydration.
- You might want to check out stockings and socks especially designed to prevent thrombosis.
Still, these tips are no alternative to professional advice. If you think you are at risk, consult your doctor if you’re up to the long travel, and for specific steps and, possibly, medications you can take.

I do a lot of long distance driving and frequently have to stop for a stretch. It is good to keep you awake as the blood pools in your feet and once it has passed through the capillaries the pumping action of the heart is no longer moving the blood around. The only thing that moves blood back to the heart in the veins is a combination of 1 way valves and the compression of the regular muscles by which we move our limbs.

Thanks for the note, Mick. Frequent stops to stretch and move during long travel is really a must. It’s just something easily forgotten, especially during long flights. With driving, you’re at least obliged to stop for gas. In the plane, a lot just veg out and wait it out.
