In the metabolic process, the human body itself is a source of pollution because its tissues and organs can produce a large amount of metabolic waste. Studies have shown that during sleep, people's respiratory tract can discharge 149 kinds of harmful substances such as carbon dioxide, and 171 kinds of chemicals can be discharged from skin pores. It has been determined that even a healthy person can discharge nearly 10 billion bacteria and viruses by breathing, talking, coughing, etc. in one night. If you have a cold, pneumonia, fart, etc., the pollution will increase. Especially in winter, the doors and windows are closed and the ventilation is poor. These chemical pollutants fill the entire room.
When people are quilt, the water discharged from the body is evaporated, and the quilt is dampened by different procedures, so that the chemical substances discharged by the human body can not be dissipated as quickly as possible on the quilt. If they are stacked immediately after getting up, these harmful chemicals are wrapped in the quilt and absorbed by the body when they are used at night, which adversely affects human health.
Therefore, do not stack and tidy the bed immediately after getting up, but turn the quilt with your hand, so that the quilt is facing outward, the door and window are opened and ventilated, so that the moisture and chemical pollutants on the quilt are naturally emitted. After washing your face and brushing your teeth, you can make your bed and fold the quilt.
