Haze's harm to individuals and society

Haze's harm to individuals and society

Smog is harmful to individuals and society. In today's society, different degrees of smog have appeared in various cities. Smoke is a combination of fog and haze. In many areas, fog and haze are used as disastrous weather phenomena for early warning and forecasting. What harm does smog do to individuals and society?

Haze harms individuals and society 1 1, and the risk of cancer increases.

As we all know, smokers are 60% more likely to get lung cancer than ordinary people, and smog contains more harmful particles, so smog is more likely to cause cancer than smoking.

2, causing various bacterial diseases

Because of the foggy weather, the sun can't shine on the earth, or the sun is weak. This will cause bacteria, viruses and microorganisms on the ground to multiply rapidly, causing diseases such as allergies.

3, prone to traffic accidents

Hazy weather will reduce visibility, only a few meters can be seen clearly. It is very dangerous for pedestrians and vehicles on the road.

Step 4 damage blood vessels

When the air pressure in dense fog is relatively low, people will feel irritable and their blood pressure will naturally rise. In addition, in foggy days, the temperature is often low. Some patients with hypertension and coronary heart disease suddenly go from warm indoor to cold outdoor, and blood vessels expand with heat and contract with cold, which will also increase blood pressure, leading to stroke and myocardial infarction.

5. Brain injury

Smog not only harms organs, but also affects the nervous system invisibly. According to experts, the 65th annual meeting of the American Geriatrics Association concluded that when PM2.5 in the air increases 10 μ g/m3, people's brain function will age for 3 years.

6. Lung injury

Smog weather has the greatest impact on the respiratory system, which has become the common sense of most people. The respiratory system has the most frequent contact with the external environment and the contact area is large. Hundreds of atmospheric particles can directly enter and adhere to the upper and lower respiratory tract and lungs of the human body, most of which will be inhaled by the human body.

The United States investigated 25,000 people with heart disease or bad heart, and found that with the increase of PM2.5, the mortality rate of patients would increase 10 μ g/m3.

7, cause cardiovascular and cerebrovascular diseases

Hazy weather, low oxygen content in the air, will make people's heart beat faster and make people feel chest tightness and shortness of breath, especially the elderly.

8, induce respiratory diseases

The composition of smog is very complicated, with hundreds of particles entering the respiratory tract through human breath. It can cause respiratory diseases, such as bronchitis and asthma.

How to reduce the harm of smog to people

1, vitamins and trace elements

Many vitamins and trace elements play an important role in preventing air pollution and maintaining heart and lung health, including vitamins C, E, A, β-carotene, and trace elements such as selenium and zinc. They have the function of regulating immunity. Foods rich in the above vitamins and trace elements include fresh fruits, vegetables, grains, meat and seafood.

2. Ensure drinking water

Drinking enough water can replenish body fluids in time, increase blood circulation and promote metabolism. At the same time, maintaining adequate drinking water and body fluid balance is helpful for the skin to form a complete sebum film and has certain resistance to air pollutants entering through skin contact.

3, adequate sleep, moderate exercise

High-quality sleep can fully repair and adjust the immune system and help improve the human immune system. After noon 10, you can exercise properly to strengthen your physique and improve your immune function.

4. Improve immunity.

Improving yourself is a safer and more powerful way to prevent the harm of smog. Immunity is the body's own defense mechanism, used to identify and eliminate any foreign objects (viruses, bacteria, etc.). ) invades from the outside, and has the ability to identify and deal with mutant cells and virus-infected cells in vivo.

Immune function is like a guardian of our human health. Only by improving immunity can we effectively prevent smog, radiation and other harm to us.

5. Minimize the entry of harmful gases.

Reducing going out in foggy days is the most direct way to reduce the harm of smog, especially for patients with cardiovascular and cerebrovascular diseases and respiratory diseases.

Remember to wear a mask when you go out, and don't open the window to reduce the pollution to the respiratory tract. Try not to open the window when upgrading in foggy days. If you really need to open the window for ventilation, try to avoid the morning and evening smog peak hours when opening the window. You can open the window a crack to prevent the wind from blowing in directly. Ventilation time should be half an hour to one hour at a time.

Haze does harm to individuals and society 2 1. Effect on respiratory tract

The smog contains nearly 20 kinds of harmful fine particles and toxic substances. Because of their small size, they can directly enter different parts of the human body from the nostrils, thus causing different symptoms.

For example, it is prone to throat inflammation, affecting the normal gas exchange in the lungs, or other respiratory diseases. Some patients with respiratory diseases are not suitable for exposure to smog, because it will worsen their condition.

Second, carcinogenicity.

Because smog is a mixture of various pollution sources, some toxic and harmful substances it carries contain carcinogenic polycyclic aromatic hydrocarbons, which can induce cancers such as lung cancer. In addition to polycyclic aromatic hydrocarbons, there are other carcinogenic compounds. In areas with serious industrial pollution, the probability of cancer will increase.

Third, it affects traffic.

As we all know, the visibility of smog weather is very low, and it is difficult for people to see things in the distance. Therefore, you should be extra careful when driving in foggy weather to avoid traffic jams or traffic accidents. Or reduce the number of times you go out in foggy days to avoid accidents.

As can be seen from the above, smog is very harmful and affects people's psychology and life. So what should we do to effectively avoid the harm of smog?

1. Reduce the frequency of going out and wear a mask when going out. In foggy days, everyone should go out as little as possible, and be sure to wear masks or other protective tools when going out. Avoid staying outdoors for a long time. After coming home from work, clean exposed skin, especially mouth and eyes, pay special attention to personal hygiene, open windows less and go out less.

2. Pay attention to diet and exercise. The improvement of immunity is particularly important, so everyone should supplement vitamins in moderation, drink more water and eat more fruits and vegetables. And pay attention to physical exercise, insist on indoor physical exercise for half an hour every day. Friends who have the habit of doing morning exercises can choose to exercise indoors or after the sun comes out. This can maintain the needs of the body and enhance the immunity to the virus.

Smog weather is very harmful to human body, so everyone should pay more attention. There are many reasons for smog, but in the final analysis, it is the deterioration of environmental problems. All of us should pay attention to environmental protection and low-carbon environmental protection in peacetime, which not only improves the environment, but also benefits ourselves. Why not?

Haze harms individuals and society by 3 1 and easily induces cardiovascular diseases.

The foggy weather is low, the humidity is high, the human body can't sweat, and the probability of inducing heart disease will be higher and higher. Smoke contains a lot of particles. These particles, including harmful substances such as heavy metals, will cause nasal diseases such as rhinitis, pulmonary sclerosis and even lung cancer once they enter the respiratory tract and stick to the alveoli.

Infectious diseases have increased.

Hazy weather will also lead to the weakening of ultraviolet rays in the surface layer, which can enhance the activity of infectious bacteria in the air and increase infectious diseases.

3. It is not conducive to children's growth.

In foggy days, due to the decrease of sunshine, insufficient ultraviolet radiation for children, insufficient production of vitamin D in the body, and greatly reduced absorption of calcium, rickets in infants and young children will be seriously caused, which will slow down the growth and development of children.

4. Affect mental health

Experts point out that continuous foggy days have an impact on people's psychology and body. Psychologically speaking, foggy days will give people a feeling of depression, which will stimulate or aggravate the state of psychological depression. In addition, due to the weak light and low air pressure in foggy days, some people will feel lazy and depressed in foggy days.

5, upper respiratory tract infection

The persistent smog weather has enveloped more than 65,438+00 provinces in China. Hazy weather, a large number of harmful substances such as dust particles and smoke particles floating in the air will cause harm to the human respiratory tract. Once inhaled by the human body, a large number of particles, dust, pollutants and viruses will stimulate and destroy the respiratory mucosa, dry the nasal cavity, destroy the defense ability of the respiratory mucosa, and bacteria will enter the respiratory tract, which is easy to cause upper respiratory tract infection.
