New research from a team of British scientists have carried out a study of the causes of DVT or deep vein thrombosis. The condition kills thousands of Britons each year and has often been attributed to the conditions found on long haul flights, especialy when seated in economy seats that offer restricted leg room.

A recent Australian study calculated the risk of a dangerous incident whilst flying long distance at around one in 40,000 and around one in 2,000 long distance passengers will suffer a blood clot (the cause of DVT). Sitting for hours in seats with restricted leg room is primarily the cause and it was found that low air pressure and reduced oxygen did not affect people by causing blood clotting among healthy people. The test was carried out on two groups of people - one group on a simulated flight and another seated for eight hours at normal ground level pressure
