Should I open or close the window in rainy days?

1. Close the window when it rains to prevent the room from getting wetter.

The humidity in the house is mainly due to the "moisture regain" of the weather. The phenomenon of "moisture regain" is manifested in the obvious increase of humidity in the air, which makes food, clothing, furniture and other items moldy. People who live in humid rooms for a long time are prone to diseases such as rheumatism, or make rheumatic patients ill or aggravate their illness.

3. The "resurgence" weather is conducive to the growth and reproduction of bacteria, which greatly increases the probability of human suffering from typhoid fever, dysentery, various digestive system diseases and skin diseases. In humid climate, sweat can't be completely absorbed by the air, and it gathers on the skin surface, which leads to the increase of body temperature and destroys the heat balance of the body. Humidity can also crack oily skin.
