Your Body Has a Second Heart Hidden in Your Feet

Every time your foot touches the ground, something happens inside you that has nothing to do with walking — you're pumping blood. Not with your actual heart, but with a second one hidden inside the sole of your foot. Most people go their entire lives without ever learning it exists. In this video, you'll discover why gravity makes returning blood from your feet a completely different problem than sending it down, how the plantar venous plexus works as a mechanical "foot pump" with every step, and why standing still for too long can leave you lightheaded when this hidden system goes quiet. You'll see why one of the most physically demanding parts of your circulation isn't happening in your chest at all.
