Cardiologists Say This Common Habit Is a Bl.ood Clot Risk

So Why Is Sitting Such a Big Deal?
It turns out that sitting for long stretches—whether during a 12-hour Netflix binge, a cross-country flight, or a regular day at a desk job—can cause blood to pool, especially in the lower legs. As blood isn’t moving, it becomes more likely to clot.

As per Dr. Danielle Belardo, a preventive cardiologist, regular movement encourages healthy blood circulation. “Your muscles help push blood through your veins. When they aren’t being used, blood flow slows down—and that’s where the danger begins,” she explains.

Dr. Mohanakrishnan Sathyamoorthy, another leading cardiologist, backs this up. He says that the condition known as venous stasis—where blood stays still in one spot too long—is among the key ingredients in the recipe for clot formation.

And here’s the kicker: you don’t have to be old or already sick to be at risk. Even healthy young adults can experience clotting problems, especially if their lifestyle includes long periods of immobility.

What Else Causes Blood Clots?
Though prolonged sitting is a big trigger, it’s not the only one. Below are some other major culprits:

1. Medical Conditions

Some conditions increase the likelihood of clotting. These include:

Can:cer and chemotherapy
Heart disease
Autoimmune disorders
Genetic clotting disorders (like Factor V Leiden)

2. Injuries or Surgeries

Major surgeries, especially involving the hips, legs, or abdomen, raise clotting risks. Why? Because recovery often involves long periods of bed rest—aka zero movement.

3. Hormonal Shifts
