What is sudden deafness? Sudden deafness, also known as sudden deafness, is a kind of sensorineural deafness that occurs suddenly within a few hours for unknown reasons, which may be accompanied by tinnitus and vertigo, without any other cerebral nerve symptoms and signs other than the auditory nerve. The incidence of sudden deafness has been increasing in recent years, and compared with the previous situation of sudden deafness in middle-aged and elderly people, the number of students suffering from sudden deafness has increased significantly, and the incidence of sudden deafness is especially concentrated before the midterm and high school exams. This is due to the fact that students are under high pressure and nervousness before examinations, and their hearing is prone to sudden deafness in a short period of time. In addition, due to social development and accelerated pace of life, white-collar workers in companies are also prone to sudden deafness due to mental tension and work pressure. The age of sudden deafness is gradually decreasing from 45 years old or above to 20 years old or even younger. Patients mostly have monaural onset and bilateral sudden deafness is rare. There is no significant gender difference in the onset of the disease, no geographical or epidemiological clustering, and there are significant cyclical or seasonal characteristics. If left untreated, sudden deafness can lead to lifelong deafness and should be taken seriously. How to prevent sudden deafness This disease is partly related to viral infections and metabolic diseases, which need to be prevented from life, such as preventing colds and regulating diet, but prevention of gene mutation needs to be done from infants and children, for example, the side effects of additives in children’s small foods and the poisoning of car exhaust when taking children for a walk on the road can be triggering factors for gene mutation. In adults, most of them are related to mental trauma and excessive physical and mental fatigue. Do not let mental states and emotions such as sadness and worry, suspicion and depression interfere with your life. It is important to resolve the stress, conflicts and stimuli related to oneself positively and maintain a healthy state of mind to prevent the “weakness of the body on the disease”. To prevent sudden deafness, we should also strengthen physical exercise to reduce the formation of blood clots, not to smoke excessively, not to drink alcohol, and to relax after a stressful day at work and not to have fun all night. In addition, heart disease, hypertension and other diseases should be actively treated.
