Too Much Sitting Can Kill You
November 2007
Many of us love to travel, whether by car, train, bus, or plane. But did you know that sitting still for long periods can be dangerous—even deadly?
The problem is an increased risk of deep blood clotting or deep vein thrombosis (DVT). The American Heart Association estimates that 1 of every 1000 Americans develops DVT each year.
DVT clots form deep inside the muscles, usually in the calf or thigh. Such a clot can "break off" and travel quickly to the lungs, with dire consequences. The most frightening aspect of a DVT is its "silence," the absence of noticeable symptoms to warn of its presence.
Experts agree: we need not be afraid to travel, but should observe these precautions to help prevent the formation of a DVT:
- When traveling by plane, particularly on a
long flight, it's important to keep moving the feet and legs to help increase blood flow.
Get up frequently, at least once an hour,
and walk down the aisle of the plane. Even when seated, be sure to move and stretch your legs periodically.
- When driving by car, take frequent rest stops to walk and stretch.
- Wearing compression hose helps maintain proper blood flow in the feet and legs, by exerting gentle pressure on the veins.
Studies have shown that wearing
compression hose can minimize the risk of developing a DVT. Compression socks that extend up to the knee are available for men, as well. These products are available at pharmacies and medical supply stores.
- Drink plenty of fluids to prevent dehydration, which reduces circulation to the feet and legs.
- Don't wear socks with a tight elastic band around the calf, as this constricts circulation.
- Don't sit with your legs crossed for long periods of time.
- Don't drink too much coffee; it reduces
blood flow.
If we run into each other while travelling, I'll be the guy wearing compression socks, drinking lots of water, walking up and down the aisle. |
