Some people, walking and falling apart; some people, listening and going deaf. Sudden deafness! Sudden deafness is a sudden onset of sensory nerve deafness of unknown cause, also known as violent deafness. This disease usually comes on quickly, with some people losing their hearing instantly, while others experience it within a few hours or days. Young people with hearing problems mostly think that they can recover in a few days after resting, not knowing that this delay is a direct cause of difficulty in restoring hearing to normal levels. The effectiveness of treatment for this disease is closely related to the time of consultation and should be treated as an emergency, within a week, and the sooner the better, as delayed treatment may lead to lifelong deafness. Mental stress is the main cause! Mental stress is one of the main causes of hearing “loss”. In the past, sudden deafness due to mental stress was mostly in people over 40 years old, but now it is spreading to young and middle-aged people. There are two peak age groups of people who suffer from ear disease due to competitive factors: high school students, college students and successful people between the ages of 35 and 60. They all have a strong competitive mentality, and their energy is often in overdraft, so they are prone to sudden deafness when they are tired for a long time without rest. Young people can also suffer from hearing loss or sudden deafness due to long-term exposure to noisy environments such as KTV and discos, and improper use of MP3s. Reduce the psychological stress! Mental health problems of children and adolescents are prominent in China. At present, China has made remarkable achievements in economic construction, but the phenomenon of only child, the increase of single-parent families, poor parenting, fierce social competition, environmental pollution, the phenomenon of new immigrants, the pressure of parents looking forward to their children and the bad social environment are all factors that seriously affect the mental development and health of children and adolescents in China. The psychological development and health level of children and adolescents are very worrying.
