Should I open the window or close it when it rains?

Windows should be closed when the weather is wet.

Generally speaking, it is recommended to close the window in wet weather, although there is more water vapor in the air in wet weather than usual. But the moisture content indoors is still less than that outdoors. Opening a window easily leads to outdoor air flowing into the room, which leads to the increase of indoor humidity. After closing the window, it can avoid internal and external air circulation to a certain extent, thus reducing indoor humidity and avoiding rheumatic diseases such as arthritis caused by moisture infection. In addition, it can also prevent indoor food and clothing from becoming moldy due to excessive moisture.

But it doesn't mean that wet weather doesn't open the window, the air doesn't circulate, and the bacteria in the air can't dissipate, which will also have an impact on our human body. Therefore, after closing the window for 2-3 hours, properly open the window to maintain air convection. In addition, 1- It is best to open the window at 2 pm 15-30 minutes. At this time, the temperature is relatively high and there is less water vapor in the air.

We will find that if there is wet weather, it is usually when it rains continuously. Before the rain, the water vapor content in the air itself was relatively high, and there was no sunlight, which caused the water vapor in the air not to dissipate completely. Reaching a certain level will make us feel particularly wet and uncomfortable.
