have you found that we haven’t seen the deep and quiet starry sky for a long time? Haven’t you breathed fresh air for a long time? With the development of industry, the air quality began to decline, which also kept us away from the nature we could be close to. Although air is essential for us, the polluted air endangers our body. What harm will air pollution do? Let’s follow and learn about it!
Chronic lung disease
speaking of diseases caused by air pollution, lung disease has undoubtedly taken the first place. Air pollution has become a major risk factor for chronic lung disease.
in a person’s life, the lungs need to process about 400 million liters of air in order to kick the dog with enough oxygen for the blood circulation system, but the air pollution is serious, so we inhale a large number of toxic substances while inhaling oxygen, which seriously affect the human respiratory system. Most of the respiratory system is composed of thin films and is very sensitive to chemicals, In particular, ozone, metals or free radicals in the air will directly destroy lung tissues and cells. Because when dealing with toxic substances, lung cells also release various powerful chemical mediators, leading to lung inflammation and lung function injury, and also affecting the function of cardiovascular system and other organs.
heart disease
air pollution will lead to heart disease, which is estimated to be unexpected for many people. If we breathe in pollutants, they will be transported to the heart through the lungs, and these pollutants may cause cell degeneration, necrosis or inflammatory reaction; It will also directly affect the beating frequency and contractility of the heart, and eventually develop into arrhythmia.
Stroke
stroke, commonly known as stroke, refers to cerebrovascular damage, local or overall brain tissue damage caused by a variety of reasons, causing clinical symptoms for more than 24 hours or fatal.
the results show that environmental PM2.5 may increase the risk of stroke and may lead to the burden of stroke in low and middle-income countries.
lung cancer
the most terrible disease is cancer. However, lung cancer is one of the most common malignant tumors in the world. One of every four cancers is lung cancer. At present, the industry recognized that the main causes of lung cancer are smoking and air pollution. Smoking is harmful to health on each box of cigarettes, We can avoid harm by not smoking, but we can refuse cigarettes but not air. The mortality rate of lung cancer is very high. There are 1.2 million new cases in the world every year, and one person dies of lung cancer almost every 30 seconds.
The nervous system
affects the nervous system. Air pollution affects the nervous system in many ways. The first is the transportation of blood, and the second is the entry of carbon monoxide in the air. It needs to be optimized to replace the combination of oxygen and hemoglobin, resulting in insufficient blood supply to the brain and large-area death of brain cells.
insomnia
causes insomnia and irritability. Perhaps you didn’t expect that the lead suspended in the air is very easy to cause damage to the nervous system, such as impaired memory, reduced response ability, weakened spatial abstract thinking ability, changes in sensory and behavioral functions, and fatigue, insomnia, irritability, headache, hyperactivity and other symptoms. If children ingest large amounts of lead compounds, they will also cause mental retardation. Air pollution has brought us great physical damage. If an air purifier is installed indoors, the air quality will be improved and the harm will be far away.
