In winter, the weather is cold, so I spend more time at home with the windows closed. However, if indoor air is not clean and dry, cold virus activity can become active and body resistance decreases, which can lead to colds. Always maintain proper temperature and humidity and ventilate frequently. I found out how to keep the air in the house warm and clean.

▫ Keep the room warm with the curtains, stick only to the glass.
In winter, the indoor temperature should be between 18 and 20 degrees Celsius. The curtains should be used with a thin layer of cloth and a thick layer of cloth. This is because thin cloth prevents  안전한토토사이트  cold energy from entering the room and thick cloth creates a warm layer of air. Also, the use of an insulated air cap, which is called a "baby," can prevent cold air entering the glass surface of a window and increase indoor temperature by preventing warm air from escaping outside. However, it is forbidden to even attach a window frame. If you block a window frame, it will not circulate air, so you should stick to the glass only because of mold.
