Should the windows be opened or closed when the weather is humid?

Window should be closed when the weather is humid.

Generally speaking, it is recommended to close windows in humid weather, although in humid weather, the air contains more water vapor than usual. However, the moisture content indoors is still less than that outdoors. Opening windows can easily cause outdoor air to flow into the room, causing the indoor humidity to increase. After closing the windows, the circulation of air inside and outside can be prevented to a certain extent, thereby reducing indoor moisture, and preventing the human body from developing rheumatic diseases such as arthritis due to moisture infection. In addition, it can also prevent indoor food and clothing from becoming moldy due to exposure to excessive moisture.

But this does not mean that if the windows are not opened in humid weather, the air will not circulate and the bacteria in the air cannot be dissipated, which will also have an impact on our human body. Therefore, after closing the window for 2-3 hours, you can open the window appropriately to allow air to maintain convection. In addition, it is best to open the windows for 15-30 minutes between 1 and 2 pm. At this time, the temperature is relatively high and there is relatively less moisture in the air.

We will find that if wet weather occurs, it is usually when it continues to rain. Before it rains, the water vapor content in the air is relatively high. Coupled with the lack of sunlight, the water vapor in the air cannot be completely dissipated. When it reaches a certain level, it will make us feel extremely wet and uncomfortable.
