1. Stop the habit of ear-pulling. Ear pulling can cause damage to the ear canal and tympanic membrane, and sometimes complicate infections and cause hearing loss. 2. Prevent water from flowing into your ears when you wash your hair or take a bath. Because the skin and tympanic membrane are soaked in water, plus the stimulation of cerumen (often called earworms and earwax), it can easily cause otitis externa. If the original tympanic membrane is perforated, water entering the ear can cause a recurrence of otitis media. 3. Physical examination is required before swimming in summer. If you have otitis externa, otitis media, cerumen embolism in the external ear canal, or tympanic membrane perforation, you should swim only after corrective treatment. 4. In case of trauma to the ear or frostbite, infection should be strictly prevented, especially Pseudomonas aeruginosa infection, because this bacterium can cause auricular cartilage periostitis, cartilage necrosis and eventually lead to auricular deformity (cauliflower-like ear). 5.Stay away from noise and explosion sites (including firecrackers) because louder noise can cause noise-induced deafness and explosive sound can cause blast deafness. 6.Stay away from tobacco, alcohol and ototoxic drugs (such as streptomycin, gentamicin, kanamycin, etc.) because they have toxic effects on the auditory nerve. 7, Viral infections (such as measles, mumps, ear shingles, etc.) are often complicated by sensorineural deafness, and preventive measures need to be taken in time. 8. Avoid blows to the head and even more so palm strikes to the ear. The former can cause hearing damage, while the latter can cause rupture of the eardrum. 9, when blowing the nose to master the correct method of blowing the nose: should be left and right nasal cavity one by one, do not pinch the left and right nostrils closed at the same time to blow the nose, because the rear of the nasal cavity and the middle ear cavity has a cavity (pharyngeal tube) connected, blowing the nose improperly can drive nasal secretions into the middle ear cavity, causing otitis media. 10.People who have colds, upper respiratory tract infections or eustachian tube dysfunction should not travel by airplane, otherwise it may cause aviation otitis media, ear pain, tympanic membrane congestion, middle ear effusion and even hearing loss. 11. Systemic diseases that cause deafness, such as hypertension and arteriosclerosis, kidney disease, diabetes and hypothyroidism can also cause deafness, so patients with these diseases should be monitored for hearing. 12. Age-related deafness is a manifestation of the aging process of the human organism in the auditory organs. The age of appearance and the rate of development vary from person to person, and it is related to genetics and various harmful factors (including diseases) experienced throughout the life course. Therefore, the elderly should have their hearing tested regularly. 13. Hearing screening should be routinely performed on newborns, and early intervention and treatment should be provided when hearing impairment is detected. If you can follow the above health care measures, many ear diseases will stay away from you and your hearing will be protected, so that the wonderful sound will always be with you.
