Your body is filled with “dead air spaces.” One of these dead air spaces is the air space within our middle ear. The middle ear is sealed by the eardrum and connected to the outer world by the Eustachian tubes running at the back of your throat.In normal everyday conditions, when the outside pressure is normal, the Eustachian tubes are closed. But as we descend in water, for instance, during a dive, the pressure of the surrounding water is higher than what we are used to on land. This causes the water to press against the eardrum bending it inward. To adapt our ears to this pressure difference, and restore the lost volume we must compensate by sending air into the inner ear through the normally closed Eustachian tube. Read More…
