Always wet ears may be caused by physiological factors, congenital greasy ears, otitis externa and other reasons. 1. Physiological factors: For example, when taking a bath or washing hair, the water accidentally enters into the ear, or when in a high temperature or strenuous exercise environment, resulting in the body discharging excessive sweat and other physiological factors, can lead to wet ears. 2. Congenital greasy ears: When there is congenital greasy ears, the cerumen glands in the ear canal will secrete greasy secretions like water, resulting in wet ears. The secretion is yellowish in color and may form yellowish crusts in the ear canal or at the opening of the ear canal, which may be accompanied by itching symptoms. 3. Otitis externa: When digging the ear frequently, it will damage the hair follicles of the external ear canal and part of the ceruminous glands, which will easily induce chronic inflammation, and then lead to moist and itchy symptoms in the external ear canal. When the ear is always wet, you should avoid water in the ear, avoid pulling out the ear frequently, and avoid eating spicy and irritating food. At the same time, it is recommended to go to the hospital specialist consultation, through the otoscopy and other examinations to clarify the cause of the disease, for targeted treatment.
