The harm of spitting, what is the harm of swallowing phlegm

After the SARS epidemic, most people have realized the harm of "spitting", so how harmful is spitting? What diseases can be transmitted by infected sputum? If you have phlegm, how do you vomit?

According to experts, 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 spit out by the patient is equivalent to the "culture medium" of bacteria, and thousands of germs will be "stationed" in a mouthful of sputum.

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 be raised in the air, and other healthy citizens can easily "get hit" by breathing these air with germs.

At the same time, experts pointed out that holding phlegm and not vomiting can also harm people. If the sputum is not excreted in the respiratory tract in time, it provides a breeding ground for bacteria to multiply, resulting in unsmooth exhalation and difficulty breathing, which may develop into emphysema; Induce coughing, repeated coughing will cause changes in the alveoli leading 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, experts pointed out that if there is phlegm, it is still necessary to "vomit quickly", but be careful not to vomit everywhere.

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

Frequent spitting is harmful to the health of the body, and the appearance of this symptom is mainly considered to be due to chronic throat inflammation, or caused by chronic bronchitis. If it is not timed**, it will get worse and worse, especially if there is chronic bronchitis.

There are germs in the phlegm that can fly everywhere with the air, and if it is infectious, it will be infected if the body has poor resistance.

What is the harm caused by swallowing phlegm in the stomach too often? After listening to the expert analysis, I regretted it!

Sputum contains a large number of pathogens such as bacteria, viruses, fungi, etc. Respiratory infectious diseases, such as epidemics, tuberculosis, tracheitis, pneumonia, measles, pertussis and diphtheria, are transmitted through sputum and are very harmful. Tuberculosis is mainly transmitted through the air, especially in patients who excrete bacteria, and when coughing, the droplets sprayed carry tuberculosis bacteria, thus transmitting to healthy people; The second is the sputum spit out by tuberculosis patients, and the tuberculosis bacteria in the sputum attach to the dust, and the sputum is dry and flies with the wind, causing the spread of tuberculosis.

Some people have tested sputum stains in public places and found that 4% to 6% of the sputum contains tuberculosis bacteria. More than 10 tuberculosis bacteria can be found in each milliliter of sputum in patients with open pulmonary tuberculosis, which shows that the bacterial content is considerable.

All of this teaches us that we can't spit. Spitting is neither hygienic nor civilized, and it is very easy to transmit diseases, which is not only harmful to others, but also pollutes the living environment and causes harm to oneself.

Therefore, in order to make our living environment cleaner, healthier and better, we must pay attention to hygiene and develop a good habit of not spitting.
