　我们人体自身的机能会随着年龄的增加而逐年下降，耳朵作为人体的一部分，自然也无法逃脱这个规律。只是不同的人因为个体差异以及生活习惯的不同，有的40岁左右听力就开始下降，而有的很大年纪了还耳聪目明。经过研究发现，科学的养生能够延缓听力下降发生。下面就让Jinghao为您分享一下听力保健方面的知识：

One keeps optimism: when people are emotionally excited, the secretion of adrenaline will increase, causing sputum in the small arteries of the inner ear, slow blood flow in small blood vessels, which will lead to blood circulation disorder, insufficient oxygen supply to the inner ear, and then suddenness deaf.

Second, adjust the diet structure: in daily life, you should eat more foods rich in zinc, iron, calcium, which can effectively expand the micro-vessels, thereby promoting the blood supply to the inner ear and preventing hearing loss.

1, pay attention to the addition of iron.

People over the age of 45 should pay attention to iron supplements. Iron-rich foods mainly include seaweed, shrimp skin, jellyfish skin, black fungus, black beans, black sesame seeds, coriander, and day lily.

2, add more zinc-rich foods

Although zinc is small in the body, it has a great effect. Studies have shown that people with tinnitus and deafness have zinc deficiency in people with 1/3, and people with 45 or older have to take 15 mg zinc per day to maintain the balance of zinc in the body. Zinc-rich foods include animal liver, whole grains, nuts, eggs, sea cucumbers, and oysters.

3, pay attention to supplement foods rich in vitamins

Vitamin C and vitamin E have the effect of increasing the dismutase of the human body, promoting the utilization of oxygen, improving the blood flow of the distal end, and protecting the inner ear. Vitamin D can promote the body’s absorption of calcium. Medical research has found that many elderly people with tinnitus are closely related to the lack of calcium in the blood. These elements are mainly contained in animal livers, eggs, mushrooms, and white fungus.
