What are the hazards of smog weather and preventive measures

Haze weather is a weather condition that has frequently occurred in recent years. It is also a natural phenomenon that causes environmental damage. In such weather, we will feel particularly depressed. While affecting our mood, it will also have serious harm to our bodies. We must pay attention to it, especially to understand the harmfulness of haze and how to prevent it. Let us take a brief look at it below.

During haze weather, the main organs that are harmful to human health due to air pollution include the respiratory tract, throat and lungs. At this time, the bacteria, viruses and fungi may be adsorbed on suspended particles smaller than 2.5 microns and enter the respiratory tract with breathing. If they grow and multiply in the throat, pharyngitis or chronic pharyngitis may occur. If they grow and multiply in the respiratory tract, respiratory tract infection may occur. If they enter the trachea, bronchi and lungs, they may cause tracheitis, bronchitis and pneumonia.

Because of the high concentration of air pollutants and low air pressure in smog weather, but sometimes the relative humidity is not too low, if people are outdoors, it is difficult for the human body to sweat, which can easily cause chest tightness and high blood pressure in the elderly, and induce acute attacks of cardiovascular and cerebrovascular diseases.

It is recommended to pay attention to personal protection and wear a mask in time during foggy and smoggy weather. It is best to use N95 type masks, which can achieve a filtration efficiency of 95% under the testing conditions specified by NIOSH standards, and most viruses, bacteria and molds can be filtered out. If this type of mask is not available, you can also use an ordinary cotton mask and spray a small amount of clean water on the outside of the mask (just until it is moist), which can also achieve better filtering effect. This will protect your health from the harm of smog weather.

There are many substances in the air during haze weather that are harmful to the human body. In such weather, we should try to reduce the opportunities and time of going out, especially we should take protective measures when going out. In addition, we should also pay attention, especially to protecting the environment, and not let the haze weather become more serious.
