1、Wooden floor
The gaps in the wooden floor are rich in organic matter and warm and humid, which can easily become a breeding ground for harmful microorganisms. After the wooden floor is used for a period of time, there are several health hazards in the gap:
First, mold. It can cause nausea, vomiting, abdominal pain, etc. In severe cases, it can cause respiratory and intestinal diseases such as asthma and dysentery.
Second, dust mites. Dust mites are one of the main causes of allergic diseases.
Third, biologically active substances. Such as pet dander, hair, saliva, etc. provide good conditions for bacterial reproduction. There is also inhalable particulate matter. Bacteria attached to these particulate matter float in the air, and when they are inhaled by the human body, they can infect diseases.
