In recent years’economy class syndrome’ has hit newspaper headlines warning us of the negative health implications of air travel.
This syndrome refers to a condition known medically as deep venous thrombosis(DVT). This is when blood clots form in the lower leg and calf area causing pain and swelling to the lower extremity. On its own a blood clot is not life threatening, but can become fatal if it gets dislodged and travels to the lungs.
So why does air travel put one at risk you may ask? Airlines in an attempt to maximise profits pack seats so close together that there isn’t enough room to move one’s legs. Also one tends to get dehydrated in flight, and the varying air pressure in the cabin does not help. Newer aircraft can take us over longer distances non-stop which means longer periods in cramped conditions.
Certain groups of people may be at particular risk.for example those who are overweight, have had recent surgery, are pregnant and those with a family history of blood clots.
Airlines have known about this problem for years and yet have done nothing to warn passengers for fear of a negative impact on air travel, which is at the end of the day, a business. The condition was highlighted a couple of years ago in the UK when a young girl in her 20’s collapsed and died after a long flight from Australia.
I have outlined a few sensible measures to reduce the risk of DVTs
(1) move around the seat and the cabin as much as possible.the air crew may not thank you for this
(2) flex calf muscles and rotate ankles at regular intervals
(3) drink plenty of fluid.avoid alcohol as this may further dehydrate you
(4) avoid boots or other restrictive shoes.soft shoes or trainers are ideal.
(5) flying long distances non-stop(for example London to Sydney) may save time; but I suggest it may be safer to break your journey.
The term’economy class syndrome’ is a bit of a misnomer, as it can occur no matter what section of the aircraft you fly.
If you have any concerns about your particular risk, it is probably wise to consult your doctor before you next fly.
Happy and healthy flying.
