Are you used to the toilet lid?

A study by New York University once found that the cyclone generated when the toilet is opened to flush can lift the microorganisms in the toilet up to 6 meters into the air, and then these microorganisms "freed" from the toilet can roam in the air, It is likely to end up on your daily utensils such as towels and tooth cups.

Are you so scared that you quickly put the toilet lid on? This habit is good, but there is no need to panic too much. Because the experimental conditions are somewhat different from reality after all. Although the siphon toilet used in the experiment is a very common type of toilet, it is easy to generate a cyclone when flushing, but not all microorganisms can take advantage of the trend to "swing up". Those who can escape smoothly are either "nail houses" in the toilet, such as Salmonella bacteria that have been attached to the surface of the sewer for a long time; or some microorganisms that are rich in lipids and can float on the water surface. The experiment uses a mixture of microorganisms and feces or culture fluid, in which the microorganisms are in a relatively free suspension state and are naturally easier to spread.

Even if some microorganisms "jailbreak" successfully, they are not all dangerous guys, and the number is quite limited. In a few cases, the toilet cyclone may bring out some pathogenic microorganisms. For example, when your stomach is infected with Mycobacterium tuberculosis and causes diarrhea, the bacteria may remain on the surface of the toilet water and spread with the cyclone. In addition, the SARS virus may also be transmitted by this way.

To sum up, daily use of the toilet cover does not have much effect, but if it is vomiting, diarrhea and other excrement that may be caused by pathogenic bacteria, it is best to cover it. If you are really worried, covering the toilet and disinfecting it regularly can reduce potential health threats.
