How about opening the window when the weather is wet?

1, it is best not to open the window. Under normal circumstances, it is easy to go out in wet weather when the rain increases. If you open the window, it is easy to increase the humidity of indoor air, leading to moldy food, clothes, furniture and other items. Living in a humid room for a long time is not good for your health. In addition, if the room is humid, it will be more conducive to the growth and reproduction of bacteria and viruses. Therefore, in wet weather, it is usually best not to open the window.

2. However, if there is virus in the air, ventilation will reduce the virus concentration formed by respiratory droplets in the air, so in this case, it is necessary to open the window for ventilation to reduce the risk of infection.
