Can you open windows for ventilation on foggy days?

Haze weather affects each of us. In such weather, we will feel a sense of panic, which will have a serious impact on our bodies. Because in haze weather, there are many harmful components in the air. The harmful substances that enter the human body through breathing will cause harm to the human body. Therefore, we must take good protection in haze weather. Can we open windows for ventilation on haze days?

Whether to open the windows on foggy days is indeed a dilemma. Experts recommend opening the windows at least twice a day: in the morning when you wake up and before you go to bed at night. Not opening windows on foggy days can certainly reduce the harm of PM2.5, but if the oxygen content in the air is insufficient, people will feel difficulty breathing. In the face of life's basic need for oxygen, the harm caused by PM2.5 will certainly not be taken into consideration. Generally speaking, the time of day when the air quality is relatively good is before going to bed at night. The air in the morning is generally more humid, making it more comfortable for people to breathe.

In addition, people will bring microorganisms and bacteria when they return home from outside, people will exhale carbon dioxide indoors, furniture, decorations, etc. will release various toxic and harmful gases, and smoking and cooking will also produce pollutants. If you don't open windows for ventilation, the amount of microorganisms and bacteria in the house will gradually accumulate and even exceed that of the outdoor air. Therefore, it is necessary to open windows for short periods of time for ventilation on foggy days. Staff at the Provincial Environmental Monitoring Station recommend that when outdoor air pollution is not very serious, windows can be opened for ventilation twice a day for 20 minutes each time under calm wind conditions. But avoid rush hours in the morning and evening and when strong winds cause dust. If there are continuous pollution days, you can hang a wet towel near the screen window when ventilating, which can play a filtering and adsorption role.

The above is about whether we can open windows for ventilation on foggy days. In such weather, we must pay attention to protection. We must also regulate our daily diet. It is also necessary to eat more foods that are good for the lungs. In addition, we must try not to go out in foggy weather and we can take measures such as wearing masks.
