Healthy ear knowledge

Our ear, which consists of three parts: the outer ear, the middle ear, and the inner ear. The outer ear receives sound from the outside world and causes the tympanic membrane to vibrate along the ear canal. The vibration of the tympanic membrane in the middle ear causes the three small bones of the hammer bone, stapes and anvil to vibrate and transmit the sound to the inner ear, which can generate nerve impulses that travel along the auditory nerve so that the sound information is transmitted to the brain. The ear is the auditory organ among the five senses of the human body, it can feel all kinds of sounds in nature, if hearing loss, hearing disorders will seriously affect the learning and life of individuals. In fact, many ear diseases can be prevented in life. Here are some ear care measures related to daily life. When washing hair or bathing, prevent water from flowing into the ear. Because the skin and tympanic membrane are soaked in water and stimulated by cerumen (often called earwax), it can easily cause otitis externa. If you have a perforated eardrum, water entering the ear will inevitably cause a recurrence of otitis media. The actual fact is that you can find a lot of people who have itchy ears, and when they get itchy, they always want to take it out for a while. If you pick up a small black hairpin and pull it out of your ear, it will easily cause ear infections if the hairpin rusts. If you have a cotton swab, it seems to be much more hygienic, but if the cotton swab is not completely sterilized during the process of ear pulling, it still won’t work. Careless ear-tucking can cause damage to the ear canal and tympanic membrane, and sometimes complicate infections and cause hearing loss. Physical examination is required before swimming. 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. Stay away from noise and continuous high intensity sound. In our daily life, the sound of car whistles, stereo sound in KTV and music sound in MP3 will mostly hurt our ears. V. Stay away from ototoxic drugs Ototoxic drugs are drugs that may cause structural damage to the inner ear, which can lead to temporary or permanent hearing loss, and can also cause more damage to existing sensorineural hearing loss. If you already have a sensorineural hearing loss, regardless of what caused it, you are more likely to experience increased hearing loss once you have taken ototoxic medications. Such as streptomycin, gentamicin, kanamycin, etc. Sixth, avoid striking the head and not to palm the ear, striking the head can be complicated by hearing damage, while palm striking the ear can cause rupture of the eardrum, life, due to external strikes that cause damage to the ear function is not uncommon. Seven, when blowing the nose to master the correct method of nasal blowing 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. If you have a cold, upper whistle infection, or eustachian tube dysfunction, you should not travel by air, as this may cause aviation otitis media, ear pain, tympanic membrane congestion, middle ear effusion, or even hearing loss. 9. Beware of other diseases systemic diseases that can cause deafness, such as hypertension and arteriosclerosis, but also kidney disease, diabetes, hypothyroidism, etc. Patients with these diseases should be monitored. Age-related deafness is a manifestation of the aging process of the human organism in the auditory organs. The age of its appearance and the speed of its development vary from person to person and are related to heredity and various harmful factors (including diseases) experienced throughout the life course. Therefore, elderly people should have their hearing tested regularly. If you have discomfort in your ears, you should go to a professional doctor for regular checkups and not handle it blindly by yourself. Especially for the elderly and children, those with high blood pressure, hyperlipidemia, diabetes, and cardiovascular disease have a high incidence of cochlear dysfunction and should be treated promptly to prevent circulatory disorders and slow down the rate of hearing loss. Only healthy ear use so that we can better protect our hearing and return our ears to a clear world.
