Why is there a higher risk of blood clots in the legs while on a long flight?


Is it just simply because of the fact that you’re sitting down for a long time without moving? I would think that the 3-4 hours I spend sitting on the couch playing video games would also give me that same risk. Or is it something to do with the altitude?

It’s mostly the sitting

You’re in a cramped space and you don’t really move. Even though you might sit still on your chair at home you do still move about. Even if you don’t do it consciously you still shift around and adjust – but you don’t really do this on a plane

But the changes in pressure do alter the oxygen levels in your blood as well which does create an additional level of risk.
