What are the specific hazards of secondhand smoke? These five points need attention

Secondhand smoke can have a great impact on the health of the respiratory system. Frequent exposure to secondhand smoke is likely to induce lung cancer. Secondhand smoke can also cause cardiovascular diseases, and in severe cases, it can even induce myocardial infarction. In addition, secondhand smoke can cause hearing impairment and increase the risk of diabetes. If women often inhale secondhand smoke, it may also cause cervical cancer.

Many people have the habit of smoking in their daily life, and they are addicted to it. They will smoke whenever they have free time, regardless of the occasion. Smoking not only harms one's own health, but also causes people around to breathe in secondhand smoke, which is no less harmful than smoking directly. So, what are the specific hazards of secondhand smoke?
1. Induce lung cancer <br/>One of the hazards of secondhand smoke is that it can induce lung cancer. Secondhand smoke contains a variety of harmful substances such as tar and nicotine, which can inhibit the activity of respiratory cilia and affect the function of macrophages, causing edema and congestion of the bronchial mucosa, leading to various respiratory diseases, which may induce lung cancer over time.
2. Cause cardiovascular diseases <br/>The harm of secondhand smoke also includes various cardiovascular diseases. Secondhand smoke contains a large amount of carbon monoxide. If people stay in a secondhand smoke environment for a long time, they will inevitably inhale a large amount of carbon monoxide, which will cause hypoxia in the human body. In addition, the nicotine in secondhand smoke can cause blood vessels to become abnormal. Long-term hypoxia and blood vessel abnormalities can greatly increase the incidence of cardiovascular diseases, and in severe cases can induce myocardial infarction.
3. Cause hearing impairment <br/>Secondhand smoke can also cause hearing impairment. Secondhand smoke contains many toxic and harmful substances, which often have adverse effects on the blood flow of small blood vessels in the ear, causing organ hypoxia and accumulation of a large amount of toxic substances, which eventually damages hearing.
4. Increase the risk of diabetes <br/> Frequent exposure to secondhand smoke will also increase the risk of diabetes. Secondhand smoke will affect the body's tolerance to glucose, thereby increasing the body's blood sugar and greatly increasing the risk of diabetes.
5. Causes cervical cancer in women <br/>Secondhand smoke contains polycyclic aromatic compounds. Once these compounds enter the human body, they will cause cervical lesions. In severe cases, they will lead to cervical cancer, threatening women's life and health. In addition, various harmful substances in secondhand smoke will affect women's reproductive health, leading to irregular menstruation and early menopause, and even infertility.
