Can the stench of the toilet seriously affect health?

Foul smell is harmful to human health, foul smell is a malignant stimulus to the human cerebral cortex, long-term stay in the foul smell environment, will cause people to produce nausea, dizziness, fatigue, loss of appetite and other symptoms. A foul-smelling environment can also worsen a disease.

The smell mainly comes from:

1) gases expelled from the gastrointestinal tract;

2) the decomposition and decay of sweat and organic matter on the skin;

3) Clothes, shoes, bedding and furniture items are unclean, moldy and rotten;

4) Stored grain, moldy and rotten;

5) The house is too close to the factory, garbage station, toilet and septic tank, which affects the cleanliness of indoor air due to air pollution.

In order to prevent foul odor pollution and improve human health, it is necessary to do a good job of personal hygiene and environmental hygiene, frequent ventilation, and frequent washing and drying of clothes and bedding.

The stench of the toilet may be volatilized by human feces. I've been thinking that manure is good for crops, because it's rich in a variety of nutrients, so it's good for the human body. Chinese have always been convenient in foul-smelling toilets, as if there is no big problem.

Is it because of the absorption of nutrients? Please discuss and advise.

Dizzy! I think it stinks so much, and it's not cool when it's convenient!

No, but who would love to stink?
