Scientists from Harvard Medical School say that a passenger who sleeps during a flight can harm his hearing..

It is reported that a passenger who sleeps during a flight may experience hearing problems.. During the entire flight, the aircraft can change the flight altitude, and this leads to ear congestion.

The reason for this phenomenon is the pressure, which outside does not correspond to the pressure inside the ear itself.. Note that you can get out of this situation with a yawn or a sip..

Note that when an airplane passenger is asleep during the flight, they cannot equalize ear pressure in this way.. As a result of this, the auditory canal will not pass sounds to the eardrum and this will lead to auditory barotrauma..

To avoid such injuries, experts advise not to sleep at the moment when the plane is climbing or landing..
