Recently the haze in the north rose, “haze full of city swallowed buildings, cloud diffuse sky cover the sun. “Some places red warning, the whole city against haze. We talk about haze, so what harm does the haze do to the human body? 1, hurt lungs, get cancer Haze days on the whistle system has the greatest impact, which has become the consensus of most people. Secondly, hazy weather leads to the weakening of ultraviolet rays in the near-earth layer, which is easy to make the activity of airborne germs increase, and the fine particles will “carry” bacteria and viruses to the depths of the whoosh system, resulting in infection. 2, sad, get infarction Harvard School of Public Health proved that the hazy days in the particulate pollutants will not only trigger myocardial infarction, but also cause myocardial ischemia or damage. The United States investigated 25,000 people with heart disease or heart is not very good, found that PM2.5 increased by 10 micrograms / cubic meter, the patient’s death rate will increase by 10 to 27%. 3, brain damage, low IQ Make blood pressure rise, leading to stroke, myocardial infarction. The 65th Annual Meeting of the American Geriatrics Society has a conclusion that PM2.5 in the air increased by 10 micrograms / cubic meter, the human brain function will be aging for 3 years. 4, injury to the kidneys, but also hurt the sperm Because the genitourinary system is the body’s fastest metabolism of the organization, when inhaled by the outside world particles into the human blood circulation is the first to be affected by the genitourinary system, will cause a number of genitourinary pathologies, such as renal failure, uremia, spermatozoa, spermatogonium malformations, prostate enlargement, and so on. A study published in the Proceedings of the National Academy of Sciences of the United States of America pointed out that the haze weather in North China reduces the life expectancy of northern residents by 5.5 years on average. The 2016 World Health Statistics report released by the World Health Organization on May 19 in Geneva showed that the global life expectancy in 2015 was 71.4 years, and China’s life expectancy was 76.1 years. To give you a brief summary, if you live in a hazy city, people’s average life expectancy is 70 years, about 72 years if a woman, and about 67 years if a man.
