To date, there is no definitive method that can be used to reverse the progression of hearing aging. However, this does not mean that age-related deafness cannot be prevented. If elderly people can pay attention to preventive health care in their daily life, they can greatly slow down the aging process of hearing. The elderly should pay special attention to nutrition and supplement zinc, iron, calcium and other trace elements, especially zinc, which have significant effects on the prevention of senile deafness. According to a survey conducted in the United States, about 1/3 of people with senile deafness who took zinc supplements for more than half a year experienced varying degrees of improvement in their symptoms. Foods rich in zinc, such as sea fish and shellfish, are good for the prevention of age-related deafness. You can also choose to take some health supplements rich in multivitamins and trace elements, such as Jin Shier Kang, Sun Cun, etc. 2. Maintain emotional stability Elderly people have poor vascular elasticity, so emotional agitation can easily lead to vasospasm in the ear, and if accompanied by high blood viscosity, it will aggravate ischemia and hypoxia in the inner ear and eventually lead to hearing loss. We can use Ginkgo biloba remedy and Salvia officinalis remedy to improve microcirculation and achieve the purpose of health care and treatment. Avoid working and living in noisy places for a long time. Among the elderly deaf patients, there are more urban residents than rural residents, which may be related to the noisy urban environment, and the incidence is also higher among the elderly who live and work in noisy environment for a long time. Therefore, elderly people should try to avoid long-term noise stimulation, and when they encounter sudden noise (such as firecrackers), they should stay away from it as soon as possible to reduce the impact and damage of noise on both ears. 3. Quit smoking and alcohol Nicotine and alcohol can directly damage the auditory nerve. Long-term heavy smoking and alcohol consumption can also lead to the occurrence of cardiovascular and cerebrovascular diseases, resulting in insufficient blood supply to the inner ear and affecting hearing. Therefore, elderly people should quit smoking and drinking. 4. Strengthen physical exercise Physical activity can promote blood circulation throughout the body, and the blood supply to the inner ear will also be improved. Exercise programs can be chosen according to specific physical conditions, such as walking, jogging, tai chi, etc., but must be adhered to.
