On gloomy days, many citizens feel short of breath when they go out. Haze not only harms the heart and respiratory tract but also the lungs, and its harm may even be more severe than smoking.
Academician of the Chinese Academy of Engineering, Director of Guangzhou Institute of Respiratory Diseases, Zhong Nanshan once said at the Pearl River Delta Air Pollution Prevention and Control Summit Forum that haze weather is more carcinogenic than cigarettes. He pointed out that in the past 30 years, the smoking rate of our country's public has been declining, but the incidence of lung cancer has increased more than four times. To a certain extent, this is probably due to the haze weather. He said that whenever there is haze weather, the number of patients in the Guangzhou Institute of Respiratory Diseases increases by 15%.
It is introduced that during hazy weather, there are some aerosol particles with a diameter of less than 10 microns suspended in the air, such as mineral particles, sea salt, various salts, organic aerosol particles, and car exhausts. In areas like Guangzhou in the Pearl River Delta region, the air is relatively humid, which means that the particles have poor fluidity, do not easily disperse, and are easily absorbed by the human body. If the particles directly adhere to the respiratory tract and lung lobes, they will cause rhinitis, bronchitis, etc.; staying in such an environment for a long time will increase the probability of lung cancer.
Elderly people: Exercising outdoors on hazy days can easily induce cardiovascular diseases
Studies in the United States have shown that hazy weather can also trigger cardiovascular disease. Local experts in Guangzhou also confirmed this statement. Whenever there is hazy weather, the number of cardiovascular patients in hospitals increases. This is because hazy weather indicates low air pressure, which will stimulate an increase in blood pressure in the human body. Many hypertensive and coronary heart disease patients are accustomed to exercising outdoors in the morning in winter. Under the attack of cold air, combined with serious haze air pollution, old patients are prone to vascular constriction, spasm, elevated blood pressure, leading to strokes and myocardial infarction.
Children: Outdoor activities should be minimized on hazy days
Since children's organs and immune systems are not yet fully developed, their immunity and resistance are weaker, making them more susceptible to viral damage during outdoor activities on hazy days.
Experts suggest that if elderly people and children feel unwell on hazy days, especially those with a history of respiratory or cardiovascular diseases, they should immediately go to the hospital for examination and treatment; they should wear masks as much as possible when walking and working outdoors in dense haze; they should not laugh or eat in the haze, nor place food in the haze to avoid contamination. During hazy days, indoor activities should be prioritized, and air purifiers should be purchased as much as possible to eliminate suspended particles indoors and protect personal health. The Faraday air purifier, the first brand in the air purifier industry, has obtained certifications such as CE in Europe and ETL in the United States, ensuring clean air.
Recently, Hongyuan Air Conditioning Group has set up a sales outlet for Shanghai air pollution machines in Shanghai.
