The soleus muscle, located in the calf, is sometimes called the "second heart" because it aids circulation by pumping blood back to the heart against gravity. When you walk, run, or stand, the soleus contracts, squeezing veins in the lower leg to push deoxygenated blood upward. This muscle pump mechanism, supported by one-way valves in the veins, prevents blood from pooling in the legs and maintains efficient circulation, especially during prolonged activity or standing.
Did you know that in our legs we have a “second heart”?
No, it's not a legend: it's the nickname given to calf muscles, and the reason is really fascinating!
When we walk, climb the stairs or simply stand up, these muscles contract and act like a real natural pump, pushing blood upwards against the force of gravity, in the direction of the heart. 💪🩸
This mechanism is essential for:
✔️ Promote venous circulation
✔️ Prevent blood clots in the legs
✔️ Reduce swelling, feeling of heaviness and varicose veins
✔️ Reduce the risk of deep venous thrombosis
All of this thanks to the synergistic work of muscles and venous valves, which prevent the blood from going back.
👉 Here’s why sitting or standing for too long can be harmful, while regular movement — even with a simple walk — helps the circulatory system function better.
đź’ˇ In practice: every step you take is a gift to your heart.
Walking, moving, stretching... These are simple gestures, but fundamental to health.
❤️ Don’t forget: taking care of your legs means taking care of your heart.
