What is the harm of spitting to our human body?

Phlegm is a secretion of the respiratory tract, and when people breathe in unclean air such as dust, these harmful components contained in the air form phlegm in the body's respiratory tract, and finally are excreted through coughing. Even for people who are in good health, the phlegm they spit out is not clean.

According to scientific experiments, a mouthful of sputum contains 50 million germs, and people with respiratory diseases will produce a large amount of sputum when infected by pathogenic microorganisms, and the sputum coughed up in a day contains at least 3 billion germs. Diseases that may be transmitted through sputum include infectious atypical pneumonia, tuberculosis, epidemics, cholera, measles, etc. Some people spit, others have the opportunity to inhale pathogenic bacteria to get sick, because the pathogenic microorganisms in the sputum will evaporate into the air, and when the wind blows, the pathogens of these diseases will rise in the air, and other healthy citizens can easily "get sick" by breathing the air with these germs.

It was learned from the press conference of the National SARS Science and Technology Research Group that the SARS virus can remain active for a long time in the three excretions of sputum, feces, urine and blood. Under 24 conditions, the virus survives for 5 days in sputum and feces and about 10 days in urine.

This undoubtedly provides strong evidence for us to fight the act of spitting.

Of course, holding phlegm and not vomiting can also harm people. If the sputum is not excreted in time in the respiratory tract, it provides a breeding ground for bacteria to multiply, resulting in unsmooth exhalation and difficulty breathing, inducing coughing, and repeated coughing will cause changes in the alveoli and lead to low function; Phlegm also contains substances that constrict the bronchial tubes, causing bronchospasm; In some patients, the sputum is antigenic, which can trigger allergic asthma. Therefore, if you have phlegm, you should still "vomit quickly", but be careful not to spit it around.

When spitting, it is best to wrap it in a tissue and throw it in the trash.

Polluting the environment affects the mood and indirectly affects the psychology, and there are many bacteria in the phlegm, which are carried away by the wind and inhaled into the human body, affecting the physiology.

Examples of slogans that do not allow spitting:1. The royal life of the city Wei Mengling is responsible, and spitting is not virtuous.

2. Speak elegantly without spitting, and only then can you be a civilized Chinese.

3. Please do not spit on Mother Earth.

4. A phlegm stain on the ground, a stain on virtue.

5. Please put the spitting in a tissue and throw it into the trash.

The dangers of spitting.

The practice of spitting is uncivilized, because the sputum contains a lot of germs, such as bacteria, viruses, etc., if the tuberculosis patient, the sputum spit out is easy to carry the tuberculosis bacillus, and the bacteria are easy to spread through the respiratory tract into normal people, thus causing the spread of tuberculosis, and then affecting the health of the public.

Sputum is the secretion of the respiratory tract, and normal people do not cough up phlegm, only people with respiratory branch system diseases are infected by foreign pathogenic bacteria, will secrete a large amount of sputum, and sputum contains a variety of virions, easy to spread through droplets, infected to healthy people, so usually do not spit, in addition, pay attention to wearing masks when going out, and go to less crowded places.

Phlegm is a secretion of the respiratory tract, and healthy people generally do not have phlegm. However, if you have a respiratory disease, you can produce a large amount of sputum when you are infected by the pathogenic organism. The sputum that the patient spits out is equivalent to that of bacteria"Culture medium", a mouthful of phlegm will be"Stationed"Thousands of germs.
