When inhaled, inhalable particulate matter can accumulate in the respiratory system and cause many diseases. Exposure to coarse particulate matter can damage the respiratory system and induce asthma. Fine particulate matter can cause heart disease, lung disease, respiratory disease, reduce lung function, etc.
Therefore, for sensitive groups such as the elderly, children and people with pre-existing heart and lung diseases, the risk is greater.
The finer the particles, the greater the harm to the human body, the particles with a particle size of more than 10 microns can be absorbed by the nose hair, and can also be discharged from the human body through coughing, while the inhalable particles with a particle size of less than 10 microns can be deposited in the lungs with human breathing, and can even enter the alveoli and blood. The highest rate of deposition in the lungs is particulate matter with a particle size of about 1 micron. These particles are deposited on the alveoli, damaging the alveoli and mucous membranes, causing chronic fibrosis of lung tissue, leading to cor pulmonale, aggravating asthma, causing a series of pathologies such as chronic nasopharyngitis and chronic bronchitis, which can be life-threatening in serious cases.
Particulate matter is particularly harmful to children and the elderly.
Inhalable particulate matter also has a strong adsorption capacity, is a "carrier" and "catalyst" for a variety of pollutants, and can sometimes become a collection of multiple pollutants, which is the main culprit of various diseases.
According to relevant data, the inhalable particulate matter diffused in the air is very small, which can reach and be deposited directly in the lungs, directly participate in blood circulation, and cause considerable harm to the human body. If the human body inhales large amounts of inhalable particles, it can cause respiratory symptoms such as shortness of breath, cough, etc., and aggravate existing respiratory diseases and damage lung tissue. Older people and children, including those with chronic pneumonia, heart disease, colds or asthma, are the most vulnerable to inhalable particulate matter.

Smoking can lead to heart disease, and smokers' lungs are black, so you can check it online and quit smoking slowly. What used to be ten a day can become nine a day, and so on. Quit smoking.

Smoking can cause coronary heart disease, and the nicotine, tar and carbon monoxide in tobacco can also slow down the blood flow in the coronary arteries, reduce blood flow, and aggravate the occurrence of myocardial ischemia.

You're going to have to ask the doctor about that.
-
Long-term smoking may lead to tracheitis, high blood pressure, heart disease, stroke, myocardial infarction, laryngeal cancer, lung cancer, pelvic osteitis, colon cancer, cataracts, vision loss and other diseases.
Smoking refers to the act of inhaling the gases produced by the combustion of tobacco into the body through the mouth, and is an unhealthy lifestyle habit.
Cigarettes contain not only nicotine but also polonium-210, and long-term smoking can lead to a series of incurable diseases.

Smoking is a bad habit that is harmful to human health. Modern medical science has proved that tobacco will release more than 1,000 kinds of compounds when burned, most of which are harmful to the human body, and there are no less than 44 kinds of carcinogens. Such as cigarette tar, nicotine (such as nicotine), carbon monoxide, aldehydes (such as benzaldehyde), amines (such as benzidine), etc.
Recent studies by Japanese scholars have shown that the smoke also contains the most toxic compounds known to date"Dioxins"。They can cause and worsen various diseases, such as cancer, pneumonia, tracheitis, high blood pressure, hyperostosis, various cardiovascular and cerebrovascular diseases, asthma, and infertility. According to the World Health Organization, about 10 million people worldwide die each year from smoking-related diseases.
Adolescents are in the period of growth and development, and the mucous membranes of the respiratory tract are easily damaged, and smoking is more harmful. According to the survey, people who start smoking at the age of 15 have a 17-fold higher incidence of lung cancer than non-smokers. Therefore, the code of conduct for primary and secondary school students in our country stipulates that students are not allowed to smoke.

Smoking is not only harmful to health, but if there are 4 manifestations of the body, please pay attention to it.
-
pharyngitis, laryngitis, chronic rhinitis, nasopharyngitis, tracheobronchitis, emphysema, coronary heart disease;
laryngeal cancer, lung cancer, stomach cancer, esophageal cancer;
vaso-obliterans of the lower extremities;
-
It can cause a variety of diseases such as cancer, cardiovascular disease, respiratory disease, etc.
-
After experts came to the conclusions: pharyngitis, laryngitis, nasopharyngitis, tracheobronchitis, emphysema, coronary heart disease;
laryngeal cancer, lung cancer, stomach cancer, esophageal cancer;
-
As soon as I smoked, I could cause lung cancer.
-
Lung cancer. Esophageal cancer.
and cardiovascular and cerebrovascular diseases.
-
In other words, as long as you smoke second-hand smoke will increase the probability of developing various diseases, but the most dangerous are cardiovascular and cerebrovascular diseases and various cancers.
For more information, please refer to the Bulletin on the Health Consequences of Exposure to Used Tobacco Smoke.

What are the dangers of long-term secondhand smoke?
-
With the improvement of living standards, the incidence of cardiovascular disease is getting younger and younger, and it is not very strange to get coronary heart disease at the age of 30.
However, coronary heart disease must be diagnosed by coronary angiography, and it is a little arbitrary to make this diagnosis just by doing an electrocardiogram.

Said yes, but no one died, and now the "scientists" said that the scary instant noodles are not eaten, causing cancer, smoking and drinking alcohol, causing cancer, this and that, you can't eat at all, people are still alive, remember, people have an immune system, my grandfather is 80 years old, his hair is barely white, more than half a catty of liquor a day, 1--2 boxes of cigarettes, and his body is good+
