Methods and skills of spitting correctly

1, you can spit on toilet paper, then wrap it and throw it in the trash can.

2. In the bathroom, you can also spit on the sink or toilet tray, but remember to wash away the sputum with water after spitting.

Through these healthy spitting methods, we can not only keep our polite image, but also avoid the harm of harmful substances in phlegm to our health, which can be described as killing two birds with one stone.

Extended data:

Spitting out phlegm can prevent harmful substances from being absorbed, but the wrong spitting method can also introduce harmful microorganisms into our surrounding environment.

When the sputum is exposed to the environment, the water in the sputum evaporates, which weakens protein's fixation of particulate matter and harmful microorganisms, so these harmful substances are more likely to enter the air and be inhaled by others.

For example, Mycobacterium tuberculosis can be suspended in the air for a long time, even in a room with poor air mobility for up to 5 hours.
