A Deep Vein Thrombosis (DVT) can be caused when blood is not returning to the heart properly and gathers - or clots - in the lower limbs. Long periods of inactivity or sitting in cramped conditions (such as on an aircraft) can hamper the normal flow of blood as the process of returning blood to the heart from the legs is normally assisted by the movement of the leg muscles.
A DVT is not actually dangerous in itself, it's the complications arising from it that can be life-threatening. If the clot detaches itself from the veins and makes its way through the bloodstream to the lungs, you could suffer from chest pains which are exacerbated by breathing and, in some cases, the coughing up of blood. In rare instances, if the clot is large, it can travel to the heart and lungs, interrupt blood flow and result in sudden death.
Using compression hosiery such as Scholl Flight Socks and Scholl Flight Socks Sheer reduces the risks associated with long haul flights by aiding the movement of blood in the veins.
Providing the extra support leg veins need, they effectively relieve that tired and achy feeling you can get, plus they can stop you getting swollen ankles meaning you arrive at your destination refreshed and ready.
For complementary methods of avoiding a DVT:
Although the risk is low, as the consequences can be so serious, everything you can do to prevent flight-related DVT is extremely important. Generally, you should wear Flight Socks, take every opportunity to exercise and drink plenty of water. Here are some do's and dont's for healthy travel:
Do -
Wear Scholl Flight Socks or Scholl Flight Socks Sheer throughout the entire journey (in fact, put them on before you leave the house or hotel)
Exercise your legs (and walk around when you can) and regularly rotate and flex your shoulders, feet and ankles
Keep well hydrated
Wear loose and comfortable clothing
Consult a healthcare professional if you are at all concerned about your legs or circulation
Don't
Drink excessive amounts of alcohol, tea, coffee or any other drink containing caffeine
Sleep in an uncomfortable position
Use a footrest if it leaves your calves dangling
Allow your calves to make prolonged contact with your seat
Place luggage where it may restrict movement of legs and feet
