What harm does smog do to the body

With the rapid increase in the number of private cars in my country, a large amount of exhaust gas is polluting our atmospheric environment every day. We can also clearly see from the weather forecast that there are more and more smog weather in my country every year. In fact, smog days are very bad for the respiratory system of some middle-aged and elderly people, and it is easy to bring them many chronic diseases. So what harm does smog do to the body?

What harm does smog do to the human body

First, it induces respiratory diseases. The composition of haze is very complex, with hundreds of particles of varying sizes. These particles enter the respiratory tract through human breathing and can cause respiratory diseases such as bronchitis and asthma.

Second, it causes cardiovascular and cerebrovascular diseases. In foggy weather, the low oxygen content in the air will accelerate the heartbeat and cause chest tightness and shortness of breath. It is especially harmful to the elderly.

Third, it causes various bacterial diseases. Because of the smog weather, the sunlight cannot reach the earth, or the sunlight is weak. This will cause bacteria, viruses and microorganisms on the ground surface to multiply rapidly, causing allergies and other diseases.

Fourth, the risk of cancer increases. As we all know, smokers are 60% more likely to develop lung cancer than ordinary people, and haze contains more harmful particles, so haze is more carcinogenic than smoking.

Fifth, it makes people feel depressed and irritable. People's mood is easily affected by the weather. When the weather is foggy and dark, and the air is polluted, people's mood will become depressed and irritable. Lack of energy in doing things.

Sixth, traffic accidents are prone to occur. Haze weather will reduce visibility, and in severe cases you can only see a few meters away. It poses a great safety hazard to pedestrians and vehicles on the road and is very dangerous.

I have explained to you the harm that smog does to the body. I hope that after reading this, you will try to avoid doing aerobic exercise outdoors when the smog is particularly severe in winter. Of course, I would also like to remind everyone that no matter how busy you are at work, try to take time to travel to the suburbs where the air is better to relax. This will not only relieve work stress, but also clean our lungs and protect our health.
