According to the results of the second National Disability Sample Survey, 2780 million, the hearing disability of adults and the elderly in China are more than 2000 million, and there are many cases of hearing loss, such as congenital deafness in children and major diseases of acquired infection. Degeneration of the elderly is a common factor. Loss of hearing can cause great troubles in life and work, and hearing loss is related to many factors. Smoking is one of them.
The Japan National Medical Center and other agencies surveyed 20 to 64 XIUX people working in eight companies. These companies have headquarters in the Kanto region of Japan. Investigators asked them to provide 50195 to 2008 years including smoking status. After the medical examination data and the follow-up investigation, the hearing has not decreased. The investigation continued until the spring of 2010. During this period, it was difficult for 2016 people to hear high-frequency sounds, and it was difficult for 3500 people to hear low-frequency sounds.
Taking into account the age and the presence or absence of hypertension, diabetes and other factors, the analysis shows that the more the number of cigarettes, the more obvious the trend of hearing decline. The risk of high frequency hearing loss is higher in people who smoke more than 21 per day compared with those who do not smoke. To be 70% higher, the risk of low-frequency hearing loss is 40% higher. At the time of the survey, there were already 5 years of non-smokers, and the risk of hearing loss was basically the same as that of non-smokers. Therefore, it can be presumed that the function of the inner ear cells is degraded due to the toxicity of nicotine and poor blood flow. E-cigarettes, which are now popular, also contain nicotine, which is expected to affect inner ear cells and increase the risk of hearing loss.
In addition, passive smoking is commonly known as “second-hand smoke”, and its harm to human health has increasingly attracted people’s attention. Although we generally know that secondhand smoke can cause damage to the health of the respiratory tract, its impact on hearing is little known. The British Broadcasting Corporation (BBC) reported that American researchers found that people who inhaled second-hand smoke for a long time had an increased risk of hearing loss.
In the study, researchers at the University of Miami and Florida International University looked at the hearing test results of 3307 non-smokers, some of whom had smoked before, while others never smoked. It was found that the risk of hearing loss in people who inhaled second-hand smoke increased by about 1/3, and those with the worst hearing loss were even more difficult to hear other people’s content in the presence of background noise.
Hearing tends to decrease with increasing frequency as you age. In addition, studies have shown that prolonged hearing loss increases the risk of developing Alzheimer’s disease.
Warm reminder: smoking is harmful to health, please try not to smoke. Pay attention to your body health every day, avoid long-term exposure to noise, eat a saturated fatty diet, and prevent senile cardiovascular disease. If you find hearing loss, you should seek medical advice promptly.
