If you don’t open the windows for ventilation for a long time, some bacteria will breed, endangering people’s lives and health. So when is the best time to open the windows for ventilation? Let me give you a detailed introduction below.

Many people are accustomed to opening windows for ventilation in the morning and evening. In fact, opening windows at this time will be counterproductive. Experts say that the reason why it is not advisable to open windows in the early morning is that around 6 o'clock in the morning, the concentration of pollutants is still very high, and the temperature in the early morning is relatively low and the air pressure is high. The tiny sand and dust, bad gases in the air are pressed by the atmospheric pressure close to the ground and are difficult to dissipate into the sky. Only when the sun rises and the temperature rises will the harmful gases slowly dissipate.
