A recent report has given thumbs down to the well talked about "economy class syndrome". It was told that there is no scientific evidence indicating that all those who are air travelling for long distances are under the risk of getting affected with blood clots.

Even those sitting in a window seats were told to be safer from any risk associated with blood clots, provided they are healthy. The revelation was made by a team led by Dr. Gordon Guyatt, a distinguished Professor of medicine at McMaster University in Hamilton.

The man is told to have thoroughly reviewed the guidelines on deep vein thrombosis, or DVT, before making the claim. It was made clear that those who are under the impression that air travelling is risky for many, must read the recent review. The team has made it clear that there is only significant risk for DVT patients if one is travelling for more than eight hours. It has been told that if one is too short or too long, they are more likely to be at risk.

"In both cases awkward positioning causes reduced blood flow which leads to stasis of the blood, increasing the risk of clots”, said guideline co-author Dr. Mark Crowther, of the department of medicine at McMaster.

Any healthy person sitting in a window seat is almost risk free. It is told that DVT triggers a blood clot in the deep veins, especially in the lower legs or pelvis, thereby inhibiting the smooth flow of blood to various parts of the body.

There are cases heard where no significant symptoms appear, however, legs get swollen, and even one suffers from pain.

It is necessary for those under the risk category to get up and move around during the flight so that reasonable risk could be reduced. Even the team has recommended calf exercises, wearing light compression stockings and sitting in an aisle seat for those under the risk, while other must stop worrying.
