Lessons from the Heart

In a time of so much noise, one of our biggest challenges is to find signal. In a sea of information - what is meaningful, what is true, what is clarifying? The question of what we choose to center is an important one. Luckily, we have to listen no further than our own heart to hear something vital.

Let us consider what the physiology of the heart might teach us about love and connection.

The heart is the vital center of our physical body, ever sending and receiving the life blood of our being. The potential action of all cells in the body depends on a phenomenon we would do well to acknowledge: depolarization. As charged particles exchange across the membrane of a cell, the electrical gradient shifts, triggering a cascade of events that allow cells to do their work. Without exchange, the membrane becomes a wall, polarity escalates, and the environment becomes hostile to healthy and coordinated life. The next part is just as important: the gradient inverts, the ions efflux, repolarizing the membrane to allow the cycle to occur again. The ebb and flow of ions, the collection and powerful release of blood from the heart, the trade of oxygen and carbon dioxide within the lungs, the breath in, the breath out - all a rhythm and a dance reflecting the universal principle of exchange.

The muscle cells within the human heart are special. Unlike smooth and skeletal muscle cells, their features allow them to synch together. The lub-dub of a healthy heart is a song of coordinated depolarization and the harmonized opening and closing of the valves that maintain the fluid boundaries within the chambers. Heart cells are also special in that they will beat on their own. However, the rate, rhythm, and strength of a heartbeat is a conversation (another exchange) between the nervous system and the heart itself. We can tune into and read this conversation when we measure heart-rate variability.

By design, the heart is a powerful, steady, and receptive organ. What better seat for the uniting and harmonizing force of Love to reside within the body? On a day when we will see hearts everywhere, let us remember what the physiology of the heart tells us about depolarization, receptivity, and vital exchange. Happy Valentine’s Day!
