In recent years, the air quality has seriously declined, and the haze weather has gradually increased. What are the hazards of smog to the human body?

1, smog hurts the lungs

The air quality drops in foggy days, and there are a lot of harmful substances in the air, which most easily affects the health of the respiratory system. Our human respiratory system is in the most frequent contact with the external environment, and harmful particles in the air will directly enter the respiratory system and then go to the lungs. Hazy weather weakens ultraviolet rays, and germs in the air are easily enhanced, which will be inhaled into the respiratory tract with air particles, causing infection.

2, the smog is sad

Medical research shows that harmful pollution particles in smog weather can cause symptoms of myocardial infarction, leading to myocardial ischemia or injury. It is suggested that people with heart disease must pay attention to protect themselves and avoid going out in foggy days.

3, smog hurts blood vessels

There are many pollutants in the air in haze weather, and the air pressure is reduced, which is easy to cause the emergency recurrence of cardiovascular diseases. When the fog is very heavy, the water vapor content in the air is high, so it is not easy to discharge the sweat in the overheated body when participating in outdoor activities, so there will be symptoms such as chest tightness, dizziness, emotional irritability and elevated blood pressure.

4, endangering the health of the respiratory system

Haze is a particulate matter that she can't see with the naked eye, but can enter the human body through breathing. If smog particles are deposited in the human body for a long time, it will have a great impact on our respiratory health and easily induce some diseases, such as asthma. Smog is also negative for lung function, which will lead to the decline of lung function.

5, increase the risk of cancer.

Hazy days will also become protective clothing for infectious diseases. The activity of some infectious bacteria and viruses will increase in foggy days, which will increase the incidence of some infectious diseases and greatly increase the chance of cancer.
