The harm of secondhand smoke

The harm of secondhand smoke

Smoking is harmful to health, and secondhand smoke is even more harmful. The following hazards need to be paid attention to, so you may want to learn more about them!

1. Secondhand smoke harms the brain. Secondhand smoke exposure causes the most direct damage to children's lungs and brain. Children's brain cells have a high metabolism and require a large amount of oxygen, but they cannot get enough oxygen in the smoke, which has a greater impact on brain cells.

2. Secondhand smoke also harms the lungs. Children's bronchial tubes are relatively straight, and the toxins in the smoke can easily enter the alveoli and accumulate in the alveoli, affecting the airway mucosa, ventilation function and immune function. If children are exposed to cigarette smoke for a long time every day, the risk of lung cancer in adulthood is three times that of children who are not exposed to passive smoking. It can also increase the risk of airway diseases such as chronic obstructive pulmonary disease, coronary heart disease, and affect heart function.

3. Secondhand smoke hurts the stomach. Frequent exposure to secondhand smoke, after nicotine enters the stomach, can easily cause problems with the digestive system. In particular, the more you smoke, the greater the damage to the stomach mucosa. Over time, the chance of gastritis will increase.

4. Secondhand smoke also harms the liver. The liver is an important detoxification site in the body. After the toxic substances contained in secondhand smoke enter the body, the liver needs to detoxify. If you are surrounded by secondhand smoke for a long time, the more toxic substances you inhale, the slower the lipid metabolism rate will be, which will cause a great burden on the liver.

5. Secondhand smoke also harms the ears. According to surveys, if people are often exposed to secondhand smoke, the chance of hearing loss will increase by 30% compared to normal healthy people. This is mainly because all organs in our body are connected. After the harmful substances in the smoke enter the body, it will cause damage to our eardrums, and hearing will easily decline over time.

Since secondhand smoke has so many harmful effects, stay away from it and persuade people around you not to smoke. It benefits others and yourself, and it is important to take care of your health!
