One of the ironies of modern life is that we can go anywhere in the world, but we often find ourselves immobilized in the process. There are a number of circumstances that render us immobile: long haul air travel - 4 plus hours (on a bad day, that might be just runway time!). Sitting in a traffic jam or driving to a distant destination. Long hours in front of the computer or TV. Any prolonged period of inactivity places us at risk for Deep Vein Thrombosis - a blood clot that can lead to health complications, even death.
The Insider is not sure why people in Great Britain are much more focused on DVT risk than Americans. In England you even can buy specific insurance for DVT. Airlines based in England are contemplating changes in seat design to reduce the risks. The threat of lawsuits might soon result in posted warnings for airline passengers.
Some people are more at risk for DVT than others. Here's a listing of risk factors, a broad net that encompasses most of us. (For more detail on these factors, check out the website).
: age - as people over 40 are at greater risk of DVT
: a past history of DVT
: a family history of DVT
: an inherited condition that makes the blood more likely to clot than usual
: recent surgery or an injury, especially to the hips or knees
: having recently had a baby
: having cancer and its treatments
: taking a contraceptive pill that contains oestrogen - but most modern pills contain a low-dose, which increases the risk by an amount that is acceptable for most women
: hormone replacement therapy (HRT) - but for many women, the other benefits outweigh the increase in risk of DVT
: treatment for other circulation or heart problems
Risk Transfer and Risk Mitigation
As with any risk, there are a number of ways to respond. Some people move immediately to risk transfer: get someone else to cover the potential loss. That's where the new insurance policies come in. If you die of DVT within 10 days of air travel, you collect 10,000 pounds. Congratulations!? This insurance is odd for several reasons: the risks are strongest after the 10 day eligibility period ends, so you might succomb from DVT but not collect anything. (Chaulk one up for the insurance actuaries!) In addition, because the insurance only pays for your death, it's really life insurance. Why bother insuring for just one potential source of your demise when a simple life policy covers you under virtually any circumstances? It's hard to imagine that DVT insurance is going to be a hot seller.
A more attractive alternative to insurance, we think, is the practical advice offered to people locked into a sedentary position: just get your blood circulating. On an airline, get up and move around. If you're driving in a car, or if you have a window seat on the plane, you can perform "traffic jam aerobics." If you are adverse to any suggestions of exercise, just make sure you stop and get out of the car for a stretch every two hours. It also helps to drink plenty of water and limit the consumption of alcoholic beverages and caffeine.
Here are some specific exercises, many of which will not be appropriate for the driver, unless the traffic is at a complete standstill:
Downward Foot Press: Press the balls of your feet down hard against the floor and raise your heels to increase the blood flow in your legs. Hold for five seconds and repeat 10 times. (Needless to add, avoid downward pressure on the accelerator!)
Shoulder Rolls: To ease the tension of sitting in one position for too long, lift the shoulders up towards the ears, roll the shoulders backwards and then down in as big a circle as you can manage. This will help to release tension in the upper back and neck, so is especially good if driving for long distances in stressful traffic.
Shoulder Press: Lift the arms to touch the car roof, take the arms outwards and back down, and repeat.
Elbow Circles: Place your fingertips on your shoulders and draw circles in the air with your elbows. Another great move to help release tension in the neck and upper back. (You might also get some interesting responses from other drivers.)
The bottom line is relatively simple. If you find yourself in a situation which severely limits your ability to move around, do something to engage the muscles of your arms and feet. A few simple risk mitigation steps will do the trick. As for the insurance, buy a lottery ticket instead. The likelihood of a payout is about the same.
