Will smog affect the oxygen content in the air? Why do you feel breathless in foggy days?

Haze will affect the oxygen content in the air, because the smog weather is due to the high concentration of PM2.5 (particles with a diameter less than 2.5 microns) in the air, which will block the tiny space in the air and reduce the oxygen content in the air.

At the same time, smog weather will make people breathless. This is because PM2.5 particles can enter the human respiratory system, causing inflammatory reaction of the respiratory system, leading to respiratory obstruction, dyspnea and other symptoms. In addition, smog weather will increase the incidence of cardiovascular diseases such as coronary heart disease and hypertension, and will also cause serious damage to air quality.

Therefore, in foggy days, you should try to avoid going out and pay attention to indoor air quality, such as using air purifiers and other measures to protect the health of yourself and your family. At the same time, the government should also strengthen environmental protection and control measures to reduce the impact of smog weather on human health.
