What effect does smog have on people's lives?

(1) on the respiratory system.

The composition of fog is very complex, including hundreds of atmospheric chemical particles. Among them, aerosol particles with the diameter less than 10 micron are the most harmful to health, such as mineral particles, sea salt, sulfate, nitrate, organic aerosol particles, fuel, automobile exhaust, etc., which can directly enter and adhere to human respiratory tract and alveoli.

Submicron particles are deposited in the upper respiratory tract, lower respiratory tract and alveoli, causing acute rhinitis and acute bronchitis. For patients with chronic respiratory diseases (such as bronchial asthma, chronic bronchitis, obstructive emphysema and chronic obstructive pulmonary disease), smoking can cause acute or acute attacks. Staying in this environment for a long time will also induce lung cancer.

(2) Effects on cardiovascular system.

Haze also has a serious impact on cardiovascular and cerebrovascular diseases, which will hinder normal blood circulation and lead to cardiovascular diseases, hypertension, coronary heart disease, cerebral hemorrhage, angina pectoris, myocardial infarction, heart failure and other symptoms, such as chronic bronchitis and pulmonary heart disease.

When the fog weather pressure is relatively low, people will feel restless and their blood pressure will naturally rise. On the other hand, the temperature in foggy days is usually low. Some patients with hypertension and coronary heart disease suddenly changed from indoor warmth to outdoor cold. Vasodilation and contraction can also increase blood pressure, leading to stroke and myocardial infarction. Therefore, patients with cardiovascular diseases must be treated carefully in time.

(3) Hazy weather will also lead to the weakening of ultraviolet rays in the near-surface layer, which will increase the activities of infectious bacteria in the air and increase infectious diseases.

(4) It is not conducive to children's growth. In foggy days, due to the decrease of sunshine, insufficient ultraviolet radiation for children, insufficient vitamin D production in the body, and greatly reduced calcium absorption, it may lead to rickets in infants and children's growth is slow.

(5) Affect mental health.

Experts point out that even cloudy and foggy days will have an impact on people's psychology and body. From the psychological point of view, vague days will lead to depressed mood, thus stimulating or aggravating the state of psychological depression. In addition, some people may feel lazy and depressed in fog because of poor light and low air pressure caused by fog.

(6) affecting reproductive capacity.

Studies have shown that the success rate of in vitro fertilization is very low for people who have been exposed to high concentrations of polluted air for a long time. The researchers also found a link between toxic air and the decline of male fertility.

20 13 1 1.5 The Green Paper on Climate Change: Climate Change Report (20 13) jointly issued by China Academy of Social Sciences and China Meteorological Bureau points out that the smog weather in China has generally increased in the past 50 years. Among them, the number of foggy days decreased significantly, the number of days increased significantly, and the process of persistent phlegm increased significantly.

Haze weather will have a significant negative impact on climate, environment, health and economy, such as acid rain and photochemical smog in urban atmosphere, which will reduce atmospheric visibility and hinder air, ground and land traffic; Increase mortality and chronic diseases, worsen respiratory and heart diseases, change lung function and structure, affect fertility and change the immune structure of the body.

Extended data:

The hazy weather should be:

1, do your own protection. Wear a high protective mask that suits your face. Wash your face, rinse your mouth and clear your nose after going out, and remove the pollution residue attached to your body. Besides facial cleaning, clean the exposed parts of the body.

2. Go out less and do less morning exercises. Reducing quitting is the most effective way to protect yourself. Especially the elderly, children, pregnant women, patients with heart disease, patients with respiratory diseases and other people who are sensitive to pollution, it is best to reduce outdoor activities in foggy days.

3. Open as few windows as possible. Try not to open the window in smoky weather. If it is really necessary to open the window for ventilation, try to open the window with smoke when 10~ 14 days is light. The time should be half an hour to an hour, not too long.

4. Eat a reasonable diet and drink plenty of water when you encounter foggy days. Chrysanthemum, olive, lily and Ophiopogon japonicus can be added. Making Chinese herbal tea containing antitussive ingredients can alleviate the problem of dry cough and reduce air pollution and lung damage.

Chinese medicine believes that warm and dry things are easy to get angry after eating. Smog is more harmful to the body, so try not to eat spicy food that is easy to get angry. I suggest you eat less light food, and you can eat some tremella, lily, pear and so on. These foods have the effects of nourishing yin, moistening lung, clearing heart fire and calming nerves. After eating, the human immunity is enhanced, thus enhancing the vitality of the lungs and reducing the harm of smog to the body.

5. Pressing the Xiang Yingke point of the acupoint is the "feeling place" and "stopping place" of the body surface. Massage can usually be used to wrap the face and dispel the cold at the top, thus enhancing the ability to resist external evils. Sticking sputum every day can also be used as a method to prevent nasal discomfort. Xiang Ying acupoints are located in the depressions on both sides of the nose, and the massage intensity is appropriate.

6. Purify indoor air. You can plant some green plants to purify the air indoors, such as aloe, cactus, green radish, chlorophytum, tiger skin, bamboo and so on.
