Compared with everyone's concern about outdoor air pollution, the harm caused by indoor air pollution to health cannot be underestimated, because people stay indoors for more than 10 years. The World Health Organization has listed indoor air pollution as one of the top ten threats to human health.
Nearly half of the world’s people are exposed to indoor air pollution
According to reports, a year-long survey by the US Environmental Protection Agency pointed out that the air pollution level in many buildings is several times that of outdoors.
A set of data from the World Health Organization shows that nearly half of the world's people are exposed to indoor air pollution, which causes chronic lung diseases and tracheitis and bronchitis. Tens of thousands of deaths worldwide every year are closely related to indoor...
According to information released by the indoor environmental protection agency, indoor air pollution is mainly caused by serious excess of indoor harmful substances caused by indoor decoration pollution, furniture pollution, kitchen fume, and outdoor heavily polluted air inflow. These harmful substances mainly include Formaldehyde, benzene, ammonia and inhalable particulate matter, etc. Women and children are disproportionately affected by illnesses caused by indoor air pollution, which is linked to a greater degree of death from conditions such as ischemic heart disease, stroke, lung cancer and chronic obstructive pulmonary disease. Our survey in several cities found that the incidence of asthma in children has continued to increase over the years. The survey also showed that the increase in asthma is related to indoor pollution because people spend more time indoors.

Xia Qing, former vice president of the Chinese Academy of Environmental Sciences, analyzed that when outdoor haze is serious, Closing doors and windows will help improve indoor air quality. However, many times due to factors such as human activities and poor air circulation, the concentration indoors will be higher than outdoors, which will affect your health.
The China Academy of Building Research conducted a survey on several buildings in Beijing from 2009 to 2016, including gymnasiums, office buildings, shopping malls, hotels, R&D centers and other public buildings. The survey results show that when traditional centralized air-conditioning fresh air units are used in public buildings, if no air purification equipment is installed, the indoor concentration is almost the same as the outdoor concentration. When there are many people moving, the indoor concentration will far exceed the outdoor concentration. .

According to research results from the School of Architecture of Tsinghua University, when the doors and windows are closed, the indoor concentration is about one-half to one-third of that outdoors. Second, these particles are mainly concentrated in the particle size range of microns to microns, that is, those small-sized and highly toxic particles among outdoor pollutants will enter the room. Of course, this is also related to the airtightness of the building itself and the frequency of opening doors and windows.
In March 2019, Tsinghua University released its first public welfare research report on indoor pollution. The results show that compared with outdoor, indoor pollution has a more significant impact on people, and the amount of indoor inhalation is twice that of outdoor.
Can it be eliminated by eating in the lungs?
There are many folk remedies for removing poison from the body, such as duck blood detoxification, fungus detoxification and so on. But the cruel fact is that when food enters the digestive system and enters the respiratory system, the digestive system cannot expel these annoying guys in the respiratory system, and the respiratory system can't do anything to get rid of them, even if it coughs up phlegm, it won't work. It is impossible to completely eliminate it by eating!
But the good news is that people can comprehensively improve the body's immunity and protect themselves from being induced to various diseases when inhaling some haze. Traditional Chinese medicine emphasizes clearing the lungs and moistening dryness, so drinking more water is always best.
Should I wash my face more times after going home in hazy days?
The answer is that you must wash your face after returning home. Girls should remove makeup and then wash their face, but there is no need to cleanse too much, so as not to cause the skin to lose its natural oil barrier and become more fragile.
Girls who love beauty may wish to turn on the fresh air system while staying at home to enjoy fresh and healthy air!
