Not To Open Windows Frequently in Cold Winter

In the cold winter, there is always heating installation at home so that the whole room would be more warm. As usual, in the night, people would close all the doors and windows to keep the heating at home while in the daytime, they often open the windows to ventilate for a long time. In their viewpoint, the air indoor should be changed frequently.

I am sure too many people would have the wrong viewpoint that the indoor temperature will decrease in cold winter when opening windows to ventilate, and then the wooden furniture are not easy to crack. In fact, with the high temperature in air, there are more moisture at the same time, which is saturated in many cases. In other words, believe it or not, the humidity indoor is too much higher that that outside. The real reason for furniture crack is the humidity, not the temperature. At this time, if you open all the windows to ventilate, the cold air will enter room and as a result the room would become more dry. It is wise to reduce ventilation time and keep constant humidity indoor.
