Whenever I yawn I temporarily lose the ability to hear. Why does this happen?
In: Biology
Your inner ear, mouth, and nose are connected as a way to equalize air pressure; otherwise severe air pressure differences (e.g. ascending in a high-speed elevator or plane) will cause extreme pain or even rupture the thin eardrum.
When you open your mouth widely (or learn to flex specific jaw muscles), eardrum mechanism “disconnects” to equalize pressures safely.
