If you’re sitting for hours on end each day, cardiologists have a clear message: stop the sedentary streak—your life may depend on it.
According to the National Blood Clot Alliance, over 900,000 Americans develop blood clots annually, and 274 people die each day from them. While clotting is a normal biological process, trouble begins when clots form unnecessarily in the veins or arteries, potentially traveling to the lungs, heart, or brain.
The No. 1 lifestyle habit doctors say you must quit? Prolonged inactivity.
“Staying still for too long—whether on a plane, at your desk, or on the couch—can lead to blood pooling in your legs and a dangerous condition called stasis,” explains Dr. Jayne Morgan, cardiologist and VP of medical affairs at Hello Heart. Regular movement keeps circulation flowing and reduces the risk of clot formation.
Dr. Mohanakrishnan Sathyamoorthy agrees: “Physical activity is essential. Even short walks or stretching breaks every hour make a huge difference.”
Other key prevention tips include:
- Stay hydrated. Dehydration thickens your blood and increases the risk of clotting, especially in the summer.
- Know your risk factors. Obesity, smoking, pregnancy, diabetes, and immobility all increase susceptibility.
- Watch for symptoms. Sudden swelling or pain in one leg, shortness of breath, chest tightness, or coughing up blood are red flags.
- Consult your doctor. Early diagnosis and treatment can prevent life-threatening complications. Simple tests and short-term blood thinners can resolve issues safely.
Bottom line? Get up, move often, drink plenty of water, and consult your doctor. Don’t wait for symptoms to take blood clots seriously—prevention starts today
