In order to prevent and delay hearing loss, we should pay attention to the following points: (1) Noise prevention in daily life. If you are exposed to various noises such as machine roar, workshop noise and human voice noise for a long time, the tiny blood vessels in the inner ear will often be in a state of spasm, the blood supply to the inner ear will be reduced, and the hearing will drop sharply. Therefore, try to avoid or reduce noise interference. (2) Maintain a good mental state. If you are often in a state of irritability, you are prone to hearing loss. So, try to keep yourself relaxed and happy. (3) massage. Massage the wind point in the depression of the earlobe and the posterior high bone, the auditory point in the depression of the anterior lower part of the tragus and the posterior edge of the mandibular joint process can increase the blood circulation of the inner ear and protect hearing. Massage once every morning and evening for 5- 10 minutes, and it will be effective if you persist for a long time. (4) pay attention to medication. Otototoxic drugs, such as gentamicin, streptomycin, kanamycin, neomycin, etc. , should be avoided as much as possible. These drugs are easy to cause ototoxicity and damage hearing, especially for patients with neurological deafness. (5) It is best not to dig your ears. Frequently digging ears with ear spoons and matchsticks can easily hurt the ear canal, cause infection and inflammation, and may also damage the eardrum. When the ear is itchy, you can gently wipe the ear canal with a cotton swab dipped in a little alcohol or glycerin, or take vitamin B, C and cod liver oil orally. (6) tonifying the kidney. Traditional Chinese medicine believes that the kidney opens in the ear, and hearing loss is closely related to kidney deficiency. So you can eat more kidney-tonifying foods, such as walnut porridge, sesame porridge, peanut porridge, pig kidney porridge and so on. These foods are quite beneficial to protecting hearing.
