Why You're Probably at Risk for Blood Clots
by Cate Stevenson, BA 

The latest health news around inactivity is not pretty. In fact, researchers at the Massachusetts General Hospital say that sitting too much could up your risk for a potentially deadly blood clot by as much as three-fold. The researchers say that their study is the first to prove that an inactive lifestyle increases the risk of developing a "pulmonary embolism." A pulmonary embolism happens when part or all of a blood clot that forms in the deep veins of your legs travels through your bloodstream to your lungs.

The study included 69,950 female nurses who were followed for 18 years. Every two years, the study participants provided details about their lifestyle habits. Women who spent most of their time sitting (more than 41 hours a week outside of work) were two times more likely to develop a pulmonary embolism than those who spent the least time sitting (less than 10 hours a week outside of work).

The link between levels of physical activity and pulmonary embolism risk remained conclusive even after accounting for such factors as age, smoking, and body mass index.
Not surprisingly, the research team also found a link between physical inactivity and high blood pressure and heart disease.

How can you prevent a pulmonary embolism? The answer is simple: stay physically active. Here are four activities that can keep you moving and using your muscles and circulatory system:

1. Ride your bike. Cycling is great for getting your legs pumping and blood flowing to your heart.

2. Go for a walk. Walking is the simplest, most effective way to stretch and keep your circulation working efficiently.

3. Jump in a pool. Swimming can take the weight off a sore back or knee while giving your muscles and heart a workout.

4. Play a team sport. Anything goes here -- baseball, hockey, soccer -- it doesn't matter. Just get out there and get active!

Remember to get your doctor's advice before starting any new exercise program or sport.

One final note: when travelling and sitting for long periods, get up and walk around if you can and do calf muscle exercises on a regular basis while en route.
