What are the hazards of haze weather?

Haze is a general term for fog and haze. Haze is a weather phenomenon, also known as haze, which refers to a large number of tiny dry dust particles such as dust, sulfuric acid, nitric acid, organic hydrocarbons, etc. floating in the air evenly, which makes the air turbid, blurs the vision and deteriorates the visibility. If the horizontal visibility is less than10000m, the sight distance obstacle caused by this non-aqueous aerosol system is called haze or haze.

Pm2.5 is closely related to smog. It has a great influence on the human body. PM2.5 will penetrate the protective structure of respiratory tract, penetrate into bronchi and lungs, directly affect the ventilation function of lungs, induce pulmonary sclerosis, asthma and bronchitis, and lead to cardiovascular diseases; PM2.5 particles can carry viruses, bacteria, radioactive dust and heavy metals in the air, which have a serious impact on respiratory system, cardiovascular system, immune system, fertility, nervous system and heredity. Weaken people's collective resistance and induce the onset of cancer. It seriously hinders the development of children's lung function and accelerates the death of the elderly with weak constitution.

How to protect yourself from the influence of PM2.5? The first is to wear an anti-fog mask when going out in foggy weather. When indoors, in foggy weather, the smog carrying PM2.5 will enter the room through the gap in the window, and indoor catering fumes will lead to indoor air pollution. How to keep the indoor air fresh? How to make yourself less affected by PM2.5? Clean up the environment at home first, and use energy-saving doors and windows, because the sealing effect of energy-saving doors and windows is very good, which can reduce the direct entry of outdoor air into the room, and then install a fresh air system on the windows. When you want to change the fresh air, you don't need to open the window, just use the fresh air system. The fresh air system can filter the outside air into the room and make the indoor air clean.
