Do you know the harm of haze to human body?

        Haze, is a combination of fog and haze. Smog is common in cities. In many areas of China, fog is combined with haze as a severe weather phenomenon for early warning and forecast, collectively known as "haze weather". Haze is the result of the interaction between specific climatic conditions and human activities. The economic and social activities of the high-density population will inevitably emit a large amount of fine particulate matter (PM 2.5). Once the emission exceeds the atmospheric circulation capacity and carrying capacity, the concentration of fine particulate matter will continue to accumulate. At this time, if affected by the static and stable weather, it is very easy to cause large-scale haze.

        Smog consists mainly of sulfur dioxide, nitrogen oxide and fine particulate matter, which combine with fog to make the sky momentarily dark and gray. Particulate matter, abbreviated as PM, is the fine particulate matter monitored by Beijing authorities. It is a pollutant particle with an aerodynamic equivalent diameter of 2.5 microns or less. The particles themselves are not only a pollutant, but also carriers of toxic substances such as heavy metals and polycyclic aromatic hydrocarbons. (Excerpt from Baidu Encyclopedia)

Haze weather is also a huge harm to the human body, the haze of these large particles and pollutants, as well as haze days brought by chain problems, are eroding people's health, such as:

• Haze weather to reduce going out, to avoid going out when the fog is thick; If you must go out, it is recommended to wear a mask with good protective effect;
  
• For people who are more sensitive to air, drink more water and pay attention to rest. If you feel unwell, go to the hospital as soon as possible.
  
• Indoor ventilation should be avoided during rush hours, and air purifier with appropriate power should be equipped to effectively improve air cleanliness.
  

In order to deal with haze, reduce the discomfort it brings to our body, and prevent potential health risks, it is necessary to take special protective measures:

• Inducing respiratory diseases: Hundreds of particles of different sizes in the haze air are brought into the respiratory tract by human breathing, which will cause bronchitis, asthma and other respiratory diseases;
  
• Cause cardiovascular and cerebrovascular diseases: haze days lead to low oxygen content in the air, will make the human heart beat faster, and then produce chest tightness, shortness of breath, cause cardiovascular and cerebrovascular diseases, especially for the elderly more harm;
  
• Cause a variety of bacterial diseases: haze weather blocks sunlight penetration, so that surface bacteria, viruses, microorganisms multiply rapidly, causing allergies and other diseases;
  
• Increased cancer risk: Smoggy air contains harmful particulate matter that may be more damaging to lung function than smoking;
  

In November 2013, the World Health Organization declared air pollutants to be "one of the most dangerous environmental carcinogens" on Earth. A large number of cases and pathology have shown that air pollution has an effect on myocardial infarction and stroke. Every breath of air we breathe should be valued for the health of us and the next generation.

Snow Mountain Clean value is to make the environment as bright and clean as snow mountain. We hope to bring clean air to more people, help more people realize the right to breathe freely, make polluted air nowhere to escape, and make every corner of the world fresh and beautiful.
