Generally speaking, people’s hearing starts to decline at the age of 60. Although this is a natural law, the age of onset and the rate of progression of senile deafness varies from person to person, and many centenarians are still deaf and bright. It is obvious that the occurrence of senile deafness is closely related to a person’s physical condition and health. Hearing is also related to the environment in which it is located and the degree of damage suffered. So, how to prevent or postpone the occurrence of deafness? 1. Avoid noise stimulation, reduce the stimulation of heavy musical instruments, listen to headphones and watch TV at a lighter volume, so as not to disturb or harm yourself. 2. Actively prevent and treat hypertension, hyperlipidemia, osteoarthrosis and endocrine diseases, and those who are able to do so should have regular physical checkups. The treatment of cardiovascular disease, osteoporosis and diabetes in the elderly as prescribed by the doctor can reduce the comorbidities. 3. Use ototoxic drugs with caution: As people grow old, their metabolic functions weaken and the excretion of toxic substances metabolized by drugs also weakens, and their tolerance decreases and sensitivity increases. 4. Eat less animal fat and offal, and eat more food rich in trace elements and vitamin C and E to improve the activity of SOD (superoxide dismutase) in the body and remove disease-causing free radicals. Vegetables, fruits, onions, ginger, garlic, etc. are good for health. 5, quit smoking and alcohol and other bad habits. 6, adhere to exercise, every day should do some ear, eye organs of health exercises. 7.When you find some hearing loss, you can take neurotrophic drugs and vasodilators. Sudden deafness should be treated promptly under the guidance of a physician. Inflammatory ear diseases should be treated early to avoid future problems.
