Not being able to hear sound in your ears can be an inconvenience. However, sometimes there is no sound from the outside world at all, but there is always a sound in your ears, which is equally annoying. This condition is known as tinnitus. Tinnitus is a symptom of hearing disorder, which is a hallucination of sound or fictitious sound, such as buzzing sound, cicada sound, or sounds like bells, insects, birds, water, wind, etc. Tinnitus can be continuous or intermittent. What are the causes of tinnitus? “Chinese medicine believes that the kidneys are open to the ears, so if the kidneys are diseased, the ears may respond. However, the causes of tinnitus are very complex and cannot be attributed to kidney deficiency. Sometimes, tinnitus can be caused by liver fire, heart fire, phlegm, or invasion of evil toxins. Guo Jun, director of the male department of Xiyuan Hospital of the Chinese Academy of Traditional Chinese Medicine, said, “From the perspective of modern medicine, some tinnitus may be the precursor of a certain disease, such as tinnitus after streptomycin injection, which means ototoxicity has occurred; tinnitus in patients with hypertension or aggravation of existing tinnitus often indicates elevated blood pressure; prolonged use of drugs such as quinine and salicylic acid can also lead to tinnitus; tympanic membrane entrapment, turbidity, adhesions, perforation, and tympanic membrane entrapment, Tinnitus can also occur in patients with hypertension or increased tinnitus. Therefore, once the symptoms of tinnitus appear, patients should actively go to the ear, nose and throat specialists in regular medical institutions for detailed examination and treatment to avoid delaying the condition.” On the basis of receiving regular treatment, tinnitus can also be prevented and reduced by adjusting usual living and eating habits. 1, avoid noise pollution: sudden loud sound and long time noise exposure can lead to hearing loss and tinnitus, so high-risk groups (working in high-intensity noise environment) should pay special attention to noise protection, such as wearing protective earmuffs, earplugs, etc.. In addition, do not use Walkman headphones for a long time and at high volume. 2.Avoid mental tension and fatigue: If you are in a state of high mental tension or physical fatigue for a long time, it is easy to aggravate tinnitus, so it is beneficial to adjust the rhythm of work and relax emotionally. 3.Rational medication: When tinnitus patients visit the doctor due to other diseases, don’t forget to tell your doctor that you have tinnitus. This is because some medications can aggravate your existing tinnitus symptoms. 4.Change bad habits: Caffeine and alcohol often aggravate tinnitus symptoms; smoking can make blood oxygen drop, and inner ear hair cells are an extremely sensitive cell to oxygen, so lack of oxygen can cause damage to hair cells. Usually, we should pay attention to eating less fatty and sweet food to prevent accumulation of phlegm and aggravation of the condition. For those who have tinnitus with kidney deficiency, it is especially important to reduce the intake of warm and dry food. 5. Eat more iron-rich food: Iron deficiency tends to harden red blood cells and reduce the ability to transport oxygen, resulting in insufficient supply of nutrients to the ear and hearing loss. Iron supplementation can effectively prevent and delay the occurrence of tinnitus and deafness in middle-aged and elderly people. Common foods with high iron content include nori, shrimp skin, black fungus, black sesame, soy products, etc. 6, eat more food containing zinc: There are many factors that lead to tinnitus and deafness, and zinc deficiency is an important reason. The zinc content in the cochlea is much higher than that in other organs, and the zinc content in the cochlea is significantly lower in elderly people over 60 years old, which leads to hearing loss. Common zinc-rich foods such as fish, beef, chicken, eggs, seafood, apples, oranges, walnuts, cucumbers, tomatoes, cabbage, radishes, etc. 7, often eat foods with blood activation: foods that activate blood circulation can expand blood vessels, improve blood viscosity, and help maintain normal microcirculation of small blood vessels in the ear. Black fungus, leek, red wine, yellow wine, etc. can be consumed frequently.
