What are the hazards of spitting?

In the street and life, we can see some people spitting everywhere. In fact, spitting is a very bad habit. Today, I will tell you about the dangers of spitting.

1. First, according to scientific experiments, one mouthful of sputum contains 50 million germs. People with respiratory diseases will produce a lot of sputum after being infected by pathogenic microorganisms, and the sputum coughed up one day contains at least 3 billion germs. All kinds of respiratory diseases may be transmitted through sputum.

2. Second: Many people will say that we are healthy people, and there are no bacteria and viruses in our sputum. Actually, this statement is quite wrong. There are many bacteria in everyone's stomach. Whether you are sick or not, bacteria will exist.

3. Third: Of course, if you hold your breath and don't spit, it will also harm people. Sputum is not discharged in time in the respiratory tract, which provides a hotbed for bacterial reproduction, leading to poor exhalation, dyspnea, induced cough, repeated cough will change alveoli, leading to low function and lung diseases.

Matters needing attention

So when there is phlegm, our best way is to wrap it in paper and throw it in the trash can, which will not affect our health and prevent the spread of diseases.
