What are the disadvantages of smog to the body? How to prevent inhalation of smog in foggy days?

Under normal circumstances, people often try to avoid going out in foggy days, because going out is greatly affected by smog. But even so, many people still don't know the specific harm of smog to the human body and how to effectively prevent smog. So what are the disadvantages of smog to the body? How to prevent inhalation of smog in foggy days?

1, the harm of smog to human body

Induce respiratory diseases

The composition of smog is very complicated, and there are hundreds of kinds of particles. These particles enter the respiratory tract through human breath, which will cause respiratory diseases such as bronchitis and asthma.

Cause cardiovascular and cerebrovascular diseases

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

Cause 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.

Increase the risk of cancer

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.

Make people depressed and irritable.

People's mood is easily influenced by the weather. Haze The weather is gloomy and the air is dirty. People's mood will also become depressed and irritable. Lack of courage in doing things.

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.

2. The method of smog self-protection

1, reducing going out is the most effective way to protect yourself, 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.

2. You can temporarily reduce morning exercises and try to go out at 10- 14. At the same time, drink more water, smoke less, stay away from "second-hand smoke" and reduce the burden on organs such as lungs and liver.

You can open a crack in the window to prevent the wind from blowing in directly, and the ventilation time should be half an hour to one hour at a time.

Protect special people

In response to the smog weather, the elderly, children, outdoor workers (such as traffic police and construction workers), pregnant women and patients with chronic diseases are treated separately according to the differences in age, occupational nature and special physiological status.

the aged

Old people spend more time indoors, so they should pay special attention to cleaning. Old people who are used to sweeping the floor with brooms might as well use vacuum cleaners, carpets, rags and sofa cover to clean in time. Traditional cooking methods, such as frying and frying, often produce a lot of oil smoke and pollute indoor air. It is recommended to cook at home by steaming and cooking.

children

Children's physical development is incomplete, and dust and particulate matter in foggy weather will directly infringe on their health through their respiratory tract, which is easy to cause respiratory diseases such as colds, coughs, rhinitis, bronchitis and asthma. The protection of children is carried out in the following aspects.

First of all, through school publicity and knowledge popularization, children have a direct relationship and sensory understanding of smog weather and its impact on health.

Secondly, raise parents' awareness of children's methods.

Thirdly, reduce outdoor activities and change outdoor activities into indoor activities, thus reducing the impact of smog on children.

In addition, in daily life, there are more dust and bacteria on the surface of plush toys. Try to play with children as little as possible or clean them frequently, so that children's activities can be kept away from heavily polluted traffic arteries, and they can live in places facing the street to avoid opening windows for ventilation during peak hours.

Outdoor worker

The persistence of smog weather will make many people feel uncomfortable outdoors, but generally speaking, we spend less time outdoors and spend most of our time indoors. But for workers who need to work outdoors for a long time, such as construction workers, sanitation workers, traffic police, etc. They are exposed to smog for a longer time and have a greater exposure. Therefore, it is necessary to emphasize and attach importance to the protection of outdoor workers against haze weather.

pregnant woman

Pregnant women should rest properly, avoid overwork, ensure adequate sleep and reduce psychological stress. At the same time, pregnant women should not rest blindly, but should exercise properly and maintain an optimistic mood.

1, eat more foods containing zinc.

2. supplement vitamin C.

3. Improve the relative humidity of indoor air.

Chronic disease population

Smog can make people with respiratory diseases such as asthma, chronic bronchitis and chronic obstructive pulmonary disease feel short of breath, chest tightness and other discomfort, which may cause lung infection or acute exacerbation. Diabetic patients are more likely to catch a cold because of their weak resistance. PM2.5 is very destructive to patients with chronic diseases such as cardiovascular and cerebrovascular diseases, which will increase the heart burden of patients with heart disease and induce cerebral infarction.

It is best to reduce going out in foggy days, and it is recommended to wear a mask with good protective effect when going out. However, not everyone is suitable to wear a mask.

Patients with respiratory diseases, especially those with dyspnea, artificially create respiratory disorders after wearing masks. Patients with heart disease, emphysema and asthma are not suitable for wearing masks for a long time. It is suggested that patients with chronic diseases avoid going out shopping and participating in various outdoor activities in the morning fog, drink plenty of water and pay attention to rest. If you feel unwell, go to the hospital as soon as possible.

Protection of professional voice users

Professional voice users, such as teachers, lecturers, singers, presenters, salespeople, etc. You often need to use your voice, which is the high incidence of throat diseases, and throat problems are more likely to occur in foggy days. It is suggested that the use of sound should be reduced as much as possible in foggy days, so that the sound can be fully rested. Wear a mask when going out, keep the indoor temperature and humidity, drink plenty of water, and drink some traditional Chinese medicine instead of tea to prevent and treat discomfort in the throat, which usually has a protective effect on sound.

3. How to raise lungs in foggy days?

1. Moisten the lungs with water

Chinese medicine says that dryness and evil are easy to hurt the lungs. Now the gap between climate change caused by air pollution and other problems is too big. For example, dry autumn is easy to take away water and cause damage to lung mucosa and respiratory tract. Therefore, hydrating is an important measure for lung maintenance. Drink at least 500ml more water every day than in other seasons. You can also pour hot water into the cup, inhale it through the nose at the mouth of the cup, and directly "shoot" the water into the respiratory tract, every time 10 minute, 2 ~ 3 times a day, to maintain the normal humidity of the lungs and respiratory tract.

2. Treat colds in time

If you catch a cold without thorough treatment, you will easily get pneumonia. So pay attention to rest when you catch a cold. If it is serious, you need to see a doctor to prevent cold sequelae.

Step 3: Do chest expansion exercises.

Advocate abdominal breathing: stretch your arms, expand your chest as much as possible, and then breathe through your abdomen, which can increase your vital capacity, especially for patients with chronic obstructive pulmonary disease and emphysema. Avoid staying in a warm room all the time, you can get some hot and cold stimulation.

Step 4: Do more back massage.

Straighten your back, close your eyes slightly, relax, and pat the center and sides of your back 30 times with your hands empty. When you beat your back, you should beat the center of your back first, and then beat the left and right sides from bottom to top. This method can dredge the qi in the chest, dredge the meridians on the back of the spine, and at the same time has the function of strengthening and nourishing the lungs.

Massage the nose

Pat your chest gently half an hour before going to bed every night to protect your heart and nourish your lungs. Specific methods: people sit up straight, keep their upper body straight, naturally separate their knees, put their hands lightly on their thighs, naturally relax, close their eyes slightly, and eliminate all distractions in their brains; Raise your hands when inhaling for a long time, and slap your palms on both sides of your chest from top to bottom; When exhaling for a long time, pat your chest with your palm from bottom to top. The time of each tap is 10 minute. Don't get up immediately after filming, but sit in a chair and breathe normally for a few minutes before getting up.

Smile more.

For the respiratory system, laughter can dilate the lungs. When people laugh, they will unconsciously take a deep breath, clean the respiratory tract, make breathing unobstructed, expand vital capacity and improve lung function.
