There are the following rules for hearing hygiene. You need to wash your ears daily. This rule must be followed as rigorously as washing your face and body and brushing your teeth. It is necessary to wash it not under running water, but slightly taking it aside so that water does not get into the ear canal. Hygiene should include not only washing the sink itself, but also the space behind it. In the crease where the ear is attached to the head, a large amount of dirt and germs accumulate, which under certain circumstances can lead to infectious diseases of the ears.
