Boring Facts About the Heartbeat to Fall Asleep To

In this calm and deliberately boring episode, you'll listen to hundreds of quiet facts about the heartbeat — the small, steady contraction that has been repeating inside your chest since before you were born. You'll hear how a tiny cluster of cells called the sinoatrial node fires an electrical signal that tells the entire heart when to squeeze, how the familiar "lub-dub" sound is really just valves opening and closing in sequence, and how your heart adjusts its pace all on its own without you ever having to think about it. There are facts about the Dutch physician who built the first electrocardiograph in a machine that weighed 270 kilograms, the blue whale whose heart slows to just two beats per minute during a deep dive, and the reason a newborn baby is calmed by the sound of a pulse it spent nine months listening to in the womb. You'll learn how the heart feeds itself in the tiny pause between beats, why athletes' hearts beat slower than average, and what happens to your heart rate during the deepest stage of sleep. None of it is especially urgent or complicated. Tonight, as you listen, you can simply rest inside the thought that even the most ordinary subject contains more quiet details than anyone could ever notice at once.
