Breathing exercises may rewire tongue control — a pilot study puts the idea to the test

This pilot study investigates whether a brief bout of respiratory muscle training can alter the brain's control over tongue muscles in healthy adults. Twenty participants will perform breathing exercises using devices that resist inhalation or exhalation, and researchers will measure tongue-muscle responses using transcranial magnetic stimulation. The goal is to uncover the neural link between breathing exercises and oral motor control, which could inform future treatments for conditions like sleep apnea and swallowing difficulties.
