Core Tip: [Many people are used to opening windows in the morning and evening. In fact, opening the window at this time will be counterproductive. Experts say that the reason why the window should not be opened in the morning is that the concentration of pollutants is still high at about 6 in the morning, while the temperature in the morning is low, the air pressure is high, and the tiny dust and bad gases in the air are pressed by atmospheric pressure. It is difficult to disperse to the high ground until it reaches the ground. Only when the sun rises and the temperature rises, the harmful gas will slowly dissipate. ]

When it is pressed by the atmospheric pressure to the ground, it is difficult to disperse to the high altitude. Only when the sun rises and the temperature rises, the harmful gas will slowly dissipate.
Before and after the dark, as the temperature drops, dust and various harmful gases begin to deposit on the ground, and it is not suitable to open the window for ventilation. The best time to open the window is 9-10 am and 3-4 pm. Because of the rising temperature during these two periods, the phenomenon of the countercurrent layer has disappeared, and the harmful gases deposited on the bottom of the atmosphere have dispersed.
