1, eat more Carrot 。 Carrot contains a lot of vitamin A. According to the study, this substance can promote the regeneration of the inner ear nerve cells. After three days of vitamin A, the hearing cells were regenerated, and the hearing increased significantly after seven days. Snail, oyster and chicken liver are also rich in vitamin A.

2, often eat iron containing food. Iron deficiency in the body can cause degeneration of erythrocytes and block the blood flow in the inner ear, resulting in hearing cell malnutrition. Eating more iron containing foods, such as crustaceans, animal liver, kelp, seaweed, Auricularia auricula and spinach, can increase blood oxygen concentration, correct the anoxia state of inner ear, improve blood circulation in inner ear, and maintain normal hearing.

3. Massage for hearing acupoints. There are two hearing aids on the ear. Earlobe The auditory canal is located at the depression of the posterior part of the ear, the anterior part of the ear, and the depression of the posterior part of the mandibular joint. Every morning and evening massage each time, 5~10 minutes each time, can increase the inner ear blood circulation, has the function of protecting hearing.

The sensitivity of the auditory nerve is closely related to the concentration of carbon dioxide in the air. When the room is closed and the carbon dioxide ratio is relatively high, the conduction of the auditory nerve will be blocked, so that the brain can not receive auditory signals. If there are more indoor green plants, especially Chlorophytum Chlorophytum and Cymbidium, the concentration of carbon dioxide will be inhibited, which is good for hearing acuity.
