Why Does Hypothermia Lead to Bradycardia?: An Explanation of the Heart's Response to Cold

As core body temperature drops, heart rate decreases proportionally, with some studies in therapeutic hypothermia showing a reduction of around 10 beats per minute for every degree Celsius lost. This slowing, known as hypothermic bradycardia, is a direct and predictable physiological response to cold exposure, explaining why hypothermia leads to bradycardia.
