Haze cannot be metabolized. When people inhale into the nasal cavity, some of them will enter the alveoli, leading to respiratory infection. In the long run, it will seriously lead to lung cancer! The other part will directly flow into the blood, which is very harmful to people's health!
It is best to wear professional protective equipment when going out in severe haze weather. Some time ago, on the road to health, you could use an air purifier for the nose of the smog star. I hope you will adopt it!
