How to prevent smog

1. Try to reduce the frequency of going out. The indoor air quality is better than the foggy weather outside.

2. Wear a mask. Choose a mask specially developed for smog. Compared with other masks, these anti-fog masks will have better effects.

3. Close the doors and windows. Because the pollutants in the air are difficult to dissipate in foggy days, doors and windows should be closed in foggy days to avoid outdoor fog entering the room to pollute the indoor air and induce acute respiratory and cardiovascular diseases.

4. Reduce exercise. A large amount of particulate dust floats in the smoky air. Once pm2.5 is inhaled into the lungs, it cannot be discharged. Reducing exercise can reduce the frequency of deep breathing and the probability of respiratory diseases.

5, pay attention to diet. Patients with chronic respiratory diseases, especially the elderly, should keep scientific life rules, avoid overwork and drink plenty of water. Pay attention to a light diet, eat less irritating food, eat more tofu, milk and other foods, and supplement vitamin D when necessary.

Extended data:

Do not prevent the harm of smog:

1, the impact on the respiratory system.

Haze particles can directly enter and attach to human respiratory tract and alveoli. In particular, submicron particles will be deposited in the upper and lower respiratory tract and alveoli respectively, 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, smog weather will make the condition acute or acute. Staying in this environment for a long time will also induce lung cancer.

2. Influence on cardiovascular system.

Hazy days also have a serious impact on cardiovascular and cerebrovascular diseases, which will hinder normal blood circulation, lead to cardiovascular diseases, hypertension, coronary heart disease, cerebral hemorrhage, and may also induce angina pectoris, myocardial infarction and heart failure. And cause pulmonary heart disease in chronic bronchitis.

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, affecting reproductive capacity.

Studies have shown that the success rate of sperm in vitro fertilization may be reduced in 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.
