1. Secondhand smoke may not only damage children's respiratory system, but also cause secretory otitis media. If you are exposed to secondhand smoke for a long time, a large amount of nicotine contained in the smoke can enter the lungs with breathing, affecting the respiratory system, and at the same time flow to all parts of the body through blood exchange, causing secretory otitis media. Moreover, long-term exposure to second-hand smoke can easily affect heart function.

Secondhand smoke is smoke released from the burning end of tobacco products, also known as passive smoking. Tobacco burning will release tar, nitrogen, nicotine and other harmful chemicals, including carcinogens. Long-term inhalation of secondhand smoke can also cause certain harm to the body. Because it mainly enters the body through breathing, it is very harmful to the respiratory system, and children may have symptoms such as cough and expectoration. At the same time, after nicotine enters the blood, the small blood vessels spasm, which leads to the hardening of the arterioles supplying blood to the inner ear, resulting in insufficient blood supply to the inner ear, which makes the mucosal veins of the middle ear dilate and stagnate, and enhances the permeability of the blood vessel wall. Tympanic leakage can easily cause secretory otitis media, and children will have symptoms such as hearing loss, earache, tinnitus and deafness.

In addition, because the surrounding people smoke and are exposed to second-hand smoke in childhood, nicotine metabolites will be detected in their blood samples, and harmful components can cause changes in blood flow, blood vessels, blood pressure and heart rate in the body, thus causing arterial vascular damage and affecting heart function. Secondhand smoke is harmful, not only to children, but also to the cardiovascular system of adults, increasing the incidence of coronary heart disease, hypertension and other reproductive system diseases such as infertility. At the same time, smoking has a great influence on yourself. It is recommended to quit smoking as soon as possible, which is good for your health and the health of your family.
