What should I do in foggy weather?

It is not recommended to open the window for ventilation in the morning and evening in foggy weather. It's best to wait until the sun comes out before opening the window for ventilation.

Step 2 wear a mask when you go out

You can wear a mask when you go out, which can effectively prevent dust particles from entering the body. Cotton masks are the best because some people are allergic to non-woven fabrics, while cotton masks are generally not allergic and easy to clean. When you come back from going out, you should wash your face and expose your skin immediately.

3. Drink more "lung-clearing and dust-removing" teas such as Tongplatycodon grandiflorum tea, Tongshen tea, Tongplatycodon grandiflorum granules and orange stalk soup.

Tongplatycodon grandiflorum tea has the functions of clearing fire and filtering lung dust, which can significantly enhance the ability of alveolar cells to expel toxic fine particles and effectively assist the human body to expel harmful substances such as PM2.5 particles accumulated in the body.

4, the right amount of vitamin D.

In winter, there is more fog and less sunshine. Due to insufficient ultraviolet radiation and insufficient vitamin D in the human body, some people will experience mental laziness and depression. If necessary, you can add some vitamin D.

5. Eat lightly and drink plenty of water

The diet in foggy days should choose light and digestible foods rich in vitamins, drink plenty of water and eat more fresh vegetables and fruits, which can not only supplement various vitamins and inorganic salts, but also play a role in moistening the lungs, resolving phlegm, relieving cough, strengthening the spleen and tonifying the kidney. Eat less irritating food and eat more pears, loquats, oranges, oranges and other foods.

6. It is best not to go out and do morning exercises.

Smog weather is a "health killer" for patients with cardiovascular diseases, especially the elderly with respiratory diseases and cardiovascular diseases. It is best not to go out in foggy days, and it is not suitable for morning exercise, otherwise it may induce diseases and even heart attacks, which may be life-threatening. Experts pointed out that foggy days are the "dangerous period" for patients with cardiovascular diseases because foggy days are depressed and the oxygen content in the air drops, which makes people feel chest tightness easily. The wet and cold fog in the morning can also cause cold stimulation, which can easily lead to vasospasm, blood pressure fluctuation and increased heart load. At the same time, some pathogens in fog can cause headaches and even induce diseases such as hypertension and cerebral hemorrhage. Therefore, people with cardiovascular diseases, especially the elderly and infirm, should not go out in foggy days, let alone do morning exercises in foggy days to avoid danger.

Haze is a general term for fog and haze. Haze is a weather phenomenon, also known as haze, which means that a large number of tiny dry dust particles, such as dust, sulfuric acid, nitric acid and organic hydrocarbons, float in the air evenly, which makes the air turbid, blurs the vision and deteriorates the visibility. If the horizontal visibility is less than10000m, the sight distance obstacle caused by this non-aqueous aerosol system is called haze or haze. When water vapor condensation intensifies and air humidity increases, haze will turn into fog. Because of the deterioration of air quality, the phenomenon of smog weather will increase and the harm will increase.
