You keep the inhaler in the backpack. You know the action plan by heart. You have seen the pediatrician, maybe the pulmonologist or the allergist. They have done the breathing tests, talked about triggers, and adjusted the medication. The inhaler does its job in the moment. But the flare-ups keep coming back, and you find yourself bracing for the next one.
Here is what most families have not been told: breathing is not only a lung function. It is a neurological function. The phrenic nerve drives the diaphragm, your child's main breathing muscle. The nerves to the lungs and airways come off the thoracic spine. The vagus nerve helps regulate the inflammatory response that decides whether airways stay calm or stay reactive.
