Have you noticed that we haven't seen the deep and quiet starry sky for a long time? Haven't breathed fresh air for a long time? With the development of industry, the air quality began to decline, which also made us far away from the nature we could get close to. Although air is indispensable to us, polluted air is harmful to our body. What harm will air pollution have?
Chronic lung disease
Speaking of the diseases caused by air pollution, lung disease is undoubtedly the first place in the world. Air pollution has become the main risk factor of chronic lung disease.
In one's life, the lungs have to deal with about 400 million liters of air in order to kick the dog with enough oxygen for the blood circulation system. However, the air pollution is serious, so we inhale a lot of toxic substances while inhaling oxygen. These substances seriously affect the human respiratory system. Most of the respiratory system is composed of membrane, which is very sensitive to chemical substances, especially in the air Ozone, metals or free radicals can directly destroy lung tissue cells. Because lung cells also release a variety of powerful chemical mediators when dealing with toxic substances, which lead to lung inflammation and lung function damage, and also affect the function of cardiovascular system and other organs.
heart disease
Air pollution can lead to heart disease, which is estimated to be a lot of unexpected. If we breathe into pollutants, it will be transported through the lungs to the heart, and these pollutants may cause cell degeneration and necrosis or inflammatory reaction; moreover, it will directly affect the beating frequency and contractility of the heart, and eventually develop into arrhythmia.
apoplexy
Stroke, commonly known as stroke, refers to a variety of causes of cerebrovascular damage, local or global brain tissue damage, causing clinical symptoms more than 24 hours or fatal.
The results show that environmental PM2.5 may increase the risk of stroke and may lead to stroke burden in low and middle income countries.
lung cancer
When talking about diseases, the most terrible one is cancer. Lung cancer is one of the most common malignant tumors in the world. One out of every four cancers is lung cancer. At present, it is generally recognized that the main causes of lung cancer are smoking and air pollution. Smoking is harmful to health on the box of each cigarette. We can avoid harm by not smoking, but we can refuse cigarettes Can reject air. The mortality rate of lung cancer is extremely high. There are 1.2 million new cases in the world every year, and almost one person dies of lung cancer every 30 seconds.
nervous system
The influence of air pollution on nervous system is caused by many aspects. The first is the transportation of blood, the second is the carbon monoxide in the air, which needs to be optimized instead of oxygen to combine with hemoglobin, resulting in insufficient blood supply to the brain and causing massive brain cell death.
insomnia
Lead to insomnia and irritability. Maybe you didn't expect that lead in the air is very easy to cause damage to the nervous system, which is memory impairment, reaction ability reduction, spatial abstract thinking ability weakening and sensory and behavioral function changes, and there will be fatigue, insomnia, irritability, headache, hyperactivity and other symptoms. If children ingest large amounts of lead compounds, it will also cause mental retardation. Air pollution has brought great harm to our health. If an air purifier is installed indoors, it will improve the air quality and keep away from the harm.
