It is said that flights over four hours double the chances of cattle class passengers developing deep vein thrombosis (DVT). The World Health Organisation (WHO) estimated in a study that over 6,000 people are at risk of DVT due to continuous long haul air travel.
A Canadian paper released the report saying, “The obese, women on birth control pills and those with blood clotting disorders are also more susceptible, as are frequent travellers and those who take very long journeys. Without regular muscle contractions, blood starts to pool in the legs and can create conditions for a clot, or thrombus, to develop in deep veins. Thrombosis can be symptom-free or trigger cramps, soreness and swelling in affected areas.”
Although chances are still relatively low for healthy travellers, it may be a good idea to wear compression stockings during long flights. Keeping the blood flowing throughout a flight will significantly aid in prevention and maintaining vein health.
