The phrenic nerve, responsible for controlling the diaphragm muscle, can also sense things as it has both motor neurons and sensory neurons. These neurons control the contraction of muscles allowing our lungs to expand when we inhale.
This podcast discusses how inhales and exhales control heart rate and how the physiological sigh can help calm you down. It also talks about heart rate variability and how box breathing can help balance heart rate.

Brian McKenzie shares insights about breathing, including common mistakes and techniques to improve your respiratory system.
