Why can I open the window to sleep when I sleep?

The reasons why you can open the window to sleep when you are asleep are as follows:

1. Don't close the window completely. Many people think that when you turn on the air conditioner at home, you must close the windows. In fact, this is wrong. The most important thing in the house is air circulation. Try to breathe fresh air, so that people will have spirit.

2. Don't open the window in the morning and evening. Generally, don't open the window before 9: 00 a.m. and around 6: 00 p.m. because of the air at these two times. The relative quality will be worse.

3, open the window on a foggy day. Many people will choose to close the window when there is zero smog, but this is not right. They should open the smaller windows properly. If the quality of the space at home is not good, don't buy an air purifier to promote indoor air circulation.

4. Don't open the window when sleeping. Usually, the bedroom space is relatively small, and we sleep for a long time. We must not open the window, and we must open the window when we sleep, which is very beneficial to our spirit.
