Many people think that the main reason that will affect human health is that there are a lot of bacteria in the feces discharged by human body. When we flush the toilet, these bacteria come out, because there is no toilet cover, which affects our health, but this theory is obviously wrong, because many places have no toilet cover at all, especially places like public toilets, but people's bodies are still very healthy, so this theory is definitely wrong. 2. A very dirty environment may affect health.
Some people's toilets often don't flush, resulting in serious odor. There must be a lot of bacteria in such a toilet. People who go to the toilet in such an environment for a long time are prone to various problems. In addition, the toilet should be ventilated frequently, which can blow out some bacteria and reduce the impact on our human body. Therefore, flushing the toilet without the toilet cover will not affect human health, but if the toilet is not cleaned and treated frequently, it will really affect human health. In short, it will not affect human health if the toilet lid is not covered when flushing. What really harms human health is the bad habit of using the toilet, such as often not cleaning the toilet, which leads to stinking, frequent ventilation, a lot of bacteria in the toilet, and the bad habit of not washing hands frequently when using the toilet. These are all things that we need to correct.
