Do you really understand HEPA filter?

What is HEPA
HEPA (High-Efficiency Particulate Air) is the most recognized high-efficiency filter material in the world. The particles having a particle diameter of 0.3 μm can be filtered, and the filtration effect is about 99.97% or more. That is to say: only 3 particles per 10,000 particles can penetrate the HEPA filter membrane.

How is the HEPA filter grade divided?
HEPA filters and the like are subdivided into G1-G4, F5-F9, H10-H14 and U15-U17 according to the current European scale. The best known H13 and H14 filters are high efficiency air filters.
The HEPA filter grade is subdivided according to the American ASHRAE rating. H11, H12, H13, and H14 are equivalent to the US M15, M16, M17, and M18 grades.
The unfolded area of ​​HEPA determines the quality of the filter, and its filtration efficiency is proportional to the expansion area. The smaller the unfolded area, the shorter the service life of the filter. On the contrary, if the area is too large, the wind pressure will increase and the air volume will be affected. Therefore, a HEPA filter that is more suitable for air purifiers must be accurately designed and adjusted several times to determine the final deployment area.

Indoor Air Quality

Indoor Air Quality

portable air purifier,home air purifier,green air purifier

Poor air quality can cause negative effects towards your health such as allergies, respiratory illnesses, and skin problems. Considering that we spend more than 90% of our time indoors, it’s important that indoor air is clean and pollutant-free to protect our health and wellbeing.

Indoor air quality statistics

According to the EPA, indoor air pollution is among the top 5 environmental risks to public health. In fact, indoor air quality can be up to 5 times worse than outdoor air quality!

Effects of indoor air pollutants towards your health may range from symptoms such as eye and throat irritation, to respiratory diseases that may arise from long term exposure to indoor pollution.

What is in indoor air

Indoor air could harbour a range of pollutants unseen to the naked eye. Airborne particles such as diesel exhaust, carbon, dust, smoke, fibres, and pollen easily enter the home through opened doors and windows.

Cooking odours, pet odours, chemicals, sink or drain smells contribute to an unhealthy variety of unpleasant and toxic household odours and gases.

Around the home, furniture, office equipment, cleaning supplies, paint, glue and varnishes are just some of the unhealthy Volatile Organic Compounds (VOCs) that are harmful to our long term health.

Not to mention, there could be a range of microorganisms such as bacteria, mould, and viruses, floating around our home!

Sources of indoor air pollutants

You may think your home air quality is perfectly fine, but these pollutants are well hidden from the naked eye. Some don’t emit a distinct smell or show obvious physical signs, so you barely notice them around your home.

However, the sources of these indoor air pollutants are everywhere in our home. Pollutants such as mould and mildew could be lingering in our bathroom and laundry room. We could also be exposed to Volatile Organic Compounds (VOCs) from paint, varnishes, upholstery, furnishing and carpets.

That’s why having an air purifier is so important at home. Air purifiers help to clean the air of unwanted pollutants. They are especially useful for those suffering from asthma or allergies.

Air purifier benefits

Air purifiers are appliances that filter out pollutants such as dust, pollen, viruses, bacteria, and odours from indoor air. With the help of air purifiers, we can improve indoor air quality and protect the health of ourselves and our families.Cleaner air provides long term benefits by reducing respiratory diseases and airborne infections caused by indoor air pollutants. Moreover, air purifiers also help to improve air circulation and eliminate mould spore buildup.Indoor air pollutants are harmful to long term health, so consider investing in an air purifier to improve indoor air quality at home.

Indoor air pollution, injury and cancer!

Indoor air pollution, injury and cancer!

portable air purifier,ozone air purifier,intelligent air purifier

In recent years, air pollution is serious, and the outside is often thick smog. The air quality monitoring webpage shows a red pass, and even a purple explosion! In the face of outdoor air pollution, you may choose to hide indoors and try to go out as little as possible. However, the indoor air actually has a variety of pollution, so don’t take it lightly. Let us look at the main sources of indoor air pollution.

Closed doors and windows can not stop PM2.5!

The first source of pollution is air pollution from the outside, with familiar particulate matter (PM). The suspended particles are measured in micrometers (μm), the suspended particles with a diameter of less than or equal to 10 microns are called PM10, and the suspended particles with a diameter of less than or equal to 2.5 microns are called PM2.5.

Why is this different? Because the damage of suspended particles to the human body varies according to their size. Our nasal filtration limit is about 30 microns, which can block hair and fine sand. The bronchial filtration limit is about 10 microns, which blocks pollen and mold. The limit of alveolar filtration is about 2.5 microns. PM2.5 is very small in size and can pass through the alveoli, directly into the blood circulation, which affects the whole body and causes a variety of injuries.

PM2.5 can adsorb harmful substances such as lead, cadmium, arsenic and manganese, which is very harmful to children. Because the proportion of children’s breathing and body weight is higher than that of adults, the time spent indoors is long. If there is too much indoor PM2.5, Children’s learning and language memory decline, it is difficult to concentrate, red eyes, dry itching, easy to have allergic conjunctivitis. The skin condition is worse and it is easy to redden and itchy. When the mucus of the respiratory tract increases, the bronchi will induce asthma. More than 50% of young children who die from pneumonia are associated with indoor air pollution.

The effect of PM2.5 on adults is also very comprehensive. In the respiratory system, it can cause asthma, lung cancer, and chronic lung obstruction. In the cardiovascular system, it is easy to cause angina, myocardial infarction, and arrhythmia. PM2.5 will increase our metabolism, gain weight and gain diabetes. PM2.5 also harms the brain, and it is easier to get diseases such as stroke, dementia, and neurodegeneration. The researchers found that for every 5 μg/m3 increase in PM2.5 exposure per year, the risk of death increased by 7%. Even in the case where the PM2.5 is lower than 25 μg/m 3 , there is such a correlation.

According to the World Health Organization, about 4.3 million deaths each year are related to indoor air pollution. Common causes of death include stroke (34%), ischemic heart disease (26%), chronic lung obstruction (22%), and pneumonia (12). %), lung cancer (6%).

The most troublesome thing is that the diameter of PM2.5 is much smaller than the gap between doors and windows. Even if the doors and windows are closed, the floating particles are completely open to the suspended particles. Stay indoors, still subject to the high concentration of PM2.5 outdoors!

Burning gas and candles inside will pollute the air.

The second source of indoor air pollution comes from indoor combustion. We cook in the house and warm in the winter. We need to burn gas stoves, stoves and other equipment. In the combustion process, carbon dioxide, nitrogen monoxide, nitrogen dioxide, sulfur dioxide, formaldehyde and the like are generated. If ventilation is poor, it may cause dizziness and headache.

Exhaust gases from steam locomotives often contain nitrogen dioxide (NO2), which enters the room through open windows. If the garage at home is next to the doors and windows, pay special attention to it.

A large number of volatile organic compounds (VOCs)

Have you ever smelled a taste when your home has just been renovated, just painted, or just put on new furniture?

Decorative partitions, cements, and furniture may have volatile organic compounds (VOCs). The most dangerous substance is formaldehyde. The formaldehyde is widely present in paints, coatings, partitions, wooden furniture and adhesives, especially high humidity and high temperature, which accelerates the volatilization of formaldehyde. Excessive exposure to formaldehyde can irritate the nose, throat, eyes, and skin, damage our respiratory tract, and are carcinogenic. These building materials and furniture may continue to release volatile organic compounds for months or even years.

Cleaning supplies are another source of indoor pollution. When cleaning the house, we will open the kitchen cleaner, the toilet cleaner, and wash it out. Then we will put a wax on the floor, put a fragrance in the toilet, or spray the insecticide in the corner. These daily necessities often contain volatile organic compounds, which easily irritate the skin and respiratory tract, and even affect the central nervous system, causing fatigue and dizziness, as well as liver and kidney function, causing chromosome damage.

Perfume, nail polish, nail polish, hair gel, deodorant, anti-mosquito, correction fluid, insecticide, brightener, computer, scented candle, etc., which are often used by everyone, are also sources of volatile organic compounds.

Spreading biological pollutants

In our living environment, bacteria, dust mites, molds, fungi and other organisms can be found everywhere, making people allergic or infected. For example, after heavy rain, wet carpets, walls, and ceilings may be moldy, and mold cells can be rotated around the city with the air. Bedding is not often changed, it will be mixed with a lot of dander and dust mites. At the toilets and sinks where water is accumulated, air conditioners, dehumidifiers, and air-conditioning filters are hotbeds of microbial growth. These indoor microorganisms may cause infectious diseases, which may cause allergies to adults and children, affecting the respiratory tract, skin, eyes, and nose. Waiting for health.

Cigarettes, incense burners, and aromatherapy are all sources of pollution!

Cigarettes release thousands of chemicals and compounds such as nicotine, tar, and carbon monoxide. Hundreds of these are toxic, and there are nearly one hundred carcinogens that can damage organs throughout the body. Not only smokers are smoked. People who are not smoking but smoke second-hand smoke are deeply affected. Nowadays, although there are regulations and regulations in public places, the family space should still pay attention. If the family wants to smoke, they must ask him to go outdoors and ventilate to avoid the smoke pollution of their families.

Incense burners and aromatherapy are of course also sources of indoor air pollution, and long-term exposure is definitely harmful to the health of the family.

Clean the air and work hard together!

After reading so many sources of pollution, everyone may be surprised. The original indoor air pollution is much more serious than we imagined, and it unwittingly infringes on our health. In order to reduce indoor air pollution, we must start from two aspects, one is to reduce pollution sources, and the other is to filter air.

Indoor air pollution is much more dirty than you think

Indoor air pollution is much more dirty than you think

ozone generator 220v,ozone generator,air purifier air home purifier

When it comes to air pollution, especially the office workers who live in big cities, they are familiar with the term ‘smog’. It can be said that everyone has learned the ability to ‘swallow the clouds and spit’ every day without knowing it. I don’t know how many harmful substances are sucked. Even those who have iron cores and lungs can’t help but absorb the “essence” of the heavens and the earth for a long time.

Outdoor air pollution cannot be ignored, and indoor air pollution should cause concern. Some people may be confused. The interior is a closed space. As long as the doors and windows are closed, how can it be polluted? Let’s see what factors are there.

Harmful substances such as formaldehyde generated in newly renovated rooms, and the emission of outdoor polluted air caused by air flow into indoors, indoor smoking, and other harmful gases, or the harmful gases generated by long-term closed doors and windows, cause indoor air pollution more than outdoor A serious and important factor.

With the development of science and technology, on the one hand, the indoor activities of human beings have greatly increased, and on the other hand, due to the serious pollution of indoor and outdoor air, they are always threatening human health. Indoor air pollution damage is not only our generation, but also affects our children. So, do you think air pollution has nothing to do with you? Do you still think that going out with a mask can avoid air pollution? Many people go out to wrap themselves very tightly, thinking that this can avoid pollution, but the indoors are also the focus of air pollution.

Life is breathing

A German man closed his breath for 22 minutes and 22 seconds, breaking the world record and not breathing in pure oxygen to close the air for 10 minutes and 12 seconds.

Breathing is invaluable for everybody we sit in. We inhale 12 cubic meters of air a day, which is equivalent to a 3 ton truck; and we breathe 28,800 times a day; we can not eat for 7 days, 3 Do not drink water in the day, but we can’t breathe for 3 minutes;

However, we spend 70% of the time indoors, for urban residents, 70% to 90% per day, home, office, shopping malls, cinemas, gyms, supermarkets, etc., so how is the indoor air to us? importance;

Cognitive Misunderstanding of Indoor Air Pollution

Misunderstanding 1: Cover the odor with air freshener

Air fresheners and perfumes can only mask the odor of pollutants. In fact, the original harmful pollutants still exist in the room, continue to affect and endanger the health of the body, and inferior air fresheners will become The source of indoor air pollution increases the degree of pollution.

Misunderstanding 2: There is odor and pollution

Among the toxic and harmful gases, some in the case of serious pollution, the concentration is greater than the human odor threshold, you can feel the obvious odor, some pollution due to their low concentration, the human sense of smell is not smelling of. At the same time, the complex smells of various substances mixed together are difficult to distinguish. Therefore, it is inaccurate to judge what pollution is by smell.

Misunderstanding 3: The use of environmentally friendly materials during renovation is not polluted.

Qualified materials mean that the content of toxic and hazardous substances is not exceeded, but not. Therefore, if the same material is used in a large amount in one room, the indoor air quality may be unqualified or even exceed the standard due to the additive effect.

Misunderstanding 4: Indoor planting can purify the air

It is generally believed that green plants have the effect of purifying air, sterilizing and vacuuming, and removing toxic substances. However, the action of plants is characterized by slow speed, long time, and very limited absorption. Some plants can produce some unpleasant smells indoors, pollen or consume oxygen in indoor air, but increase indoor air pollution.

Misunderstanding 5: Harmful gases come from renovation

This is an incorrect view. For example, the main source of ammonia is concrete with additives such as antifreeze, and ammonia can be released from human waste; cigarette smoke and kitchen smoke can produce formaldehyde, benzene, TVOC, etc. Contaminants. In China, due to the large number of applications of various benzene-containing solvents, the common presence of benzene in indoor and outdoor ambient air is relatively low. Relatively speaking, the proportion of benzene pollution generated by cigarette smoke is relatively low, but this indicates that the degree of indoor air pollution in China is more serious.

Misunderstanding 6: Purify the air inside the car with perfume

After the new car leaves the factory, the concentration of toxic gas in the car is high, and the volatilization time can last for more than 6 months, which can cause dizziness, nausea, drowsiness, cough, sneezing and other discomforts, and even lead to serious diseases such as leukemia. At present, many perfumes are not naturally extracted.

Misunderstanding 7: Fortunately

Everyone’s physical fitness and resistance adaptability are different. Not all people will develop in the same harsh environment, so some people are lucky. This is not true. According to surveys of relevant international organizations, indoor air pollutants that are harmful to health are found in 30% of new and rebuilt buildings in the world, and 68% of diseases are caused by indoor air pollution.

Indoor indoor air pollution

Indoor indoor air pollution

home oxygen generator,air home purifier,air purifier air home purifier

When it comes to air pollution, the first thing that people think of may be smog, PM2.5, dust, and formaldehyde, but they often overlook important points: microbial contaminants such as bacteria, fungi, and viruses. According to a report in the Journal of the Royal Society of B (Biosciences), the microbes that we ‘co-located’ include more than 7,000 bacteria and more than 2,000 fungi, many of which may induce various acute infectious diseases. Pathogenic bacteria. Indoor bacterial contamination is a serious threat to human health and can cause various diseases such as various respiratory diseases, asthma, and building syndrome.

Biological pollution

Definition: Pollutants, allergens and other pathogens and allergens that are harmful to humans and organisms pollute water, gas, soil and food, affecting biological production and endangering human health. For example, pollution caused by bacteria, aphids, SARS viruses, and avian influenza viruses.

Characteristics of biological pollution:

First, it is difficult to predict, and it is difficult to predict when and where foreign creatures will invade.

Second, the incubation period is long. After an alien invasion, the incubation period lasts for several years, even decades. Therefore, it is difficult to be discovered and it is difficult to follow up.

The third is destructive, unconsciously, various rashes, viral infections, etc. appear on the skin.

Biological pollution can be divided into: according to different species:

Animal pollution (mainly harmful insects, parasites, protozoa, aquatic animals, etc.)

Plant pollution (weed is the most common contaminant species, as well as certain tree species and algae, etc.)

Microbial contamination (including viruses, bacteria, fungi, etc.).

source:

Indoor biological pollution includes bacteria, fungi (including fungal spores), filter viruses, dust mites, Legionella, animal dander and biologically active substances, Escherichia coli, Staphylococcus aureus and the like.

Biological pollution can be divided into four categories:

First, mold, it is the main cause of allergic diseases

The second is pollen from plants, such as the sycamore pollen mentioned above.

The third is bacteria and viruses carried by humans, animals, soil and plant debris.

The fourth is dust mites and hair and dander from cats, dogs and birds.

Raw material pollution

In the early stage of collection and processing of food raw materials, many bacteria are often attached to the surface, especially fruits, vegetables, meat and aquatic products with damaged surfaces. Cooking utensils and tableware are contaminated.

Processing pollution

Processed foods are mostly packaged foods, generally cleaner, but also subject to secondary pollution. When the sanitary condition of the kitchen is poor, the bacteria floating in the air will settle to the surface of the food; during the cooking process, if you do not pay attention to the separation of raw and cooked, the bacteria will be transferred from the fresh food or semi-finished products to the cooked food, causing the food to cross. Pollution; food cooking and processing personnel can directly or indirectly cause bacterial contamination of food through their hands, clothes, respiratory tract, hair, etc. if they do not pay attention to personal hygiene or infectious diseases; seasonings used in cooking and processing (such as soy sauce) ) and if water contains bacteria, it can also cause bacterial contamination of food.

Indoor pollution

For example: air conditioning pollution

When the air conditioner circulates through the air duct, the bacteria and microorganisms carried in it gradually become more and more, and a secondary pollution source is formed, which causes the bacteria to multiply.

Food contamination

Harmful microorganisms and parasites or eggs contaminate food, which can cause food to spoil or produce toxins, poisoning people after eating, or causing parasitic diseases.

Indoor air quality has always been a public blind spot for public awareness

Indoor air quality has always been a public blind spot for public awareness

ozone generator price,ozone generator price,ozonizer

Tsinghua University released the ‘National Indoor Indoor PM2.5 Air Pollution Research Report’, which was jointly initiated by the Department of Electronic Engineering of Tsinghua University, the Building Environment Monitoring Center of Tsinghua University and the Southern Weekend Green News Department.

The indoor PM2.5 intake is 4 times that of the outdoor; during the sampling period, there is 1/3 of the time, and the indoor air is at the ‘pollution’ level. Under the same external conditions, the indoor level of the PM2.5 above the 17th floor is the best, and the indoor level below the 8th floor is the worst. The indoor level of the office environment is slightly better than the living environment.

Recently, indoor PM2.5 air pollution has gradually received attention from all parties. At the end of 2014, researchers in Shenyang sent professional testers to check indoor PM2.5 for free in the registration family, and planned to collect 1,000 survey samples. In early 2015, Wuxi began to set up 75 monitoring in 17 public places in the city. Point, detecting indoor air quality; in Barcelona, ​​Spain, the micro-assembly laboratory (Fab Lab) is also engaged in the collection of relevant air quality data, the laboratory director Thomas Diez told Southern Weekend reporters, the laboratory is collecting worldwide Volunteers recently installed two sensing devices in China.

However, the traditional detection method has the problem of poor generalization. ‘What we have been very annoyed in the past is how to obtain the indoor air data of the country, the research and testing by researchers everywhere, the personnel and the cost are too high,’ said Mo Jinhan, an associate professor at the School of Architecture at Tsinghua University.

In the eyes of Zhang Lin, who has been researching wireless sensor networks, sensors and big data, coupled with low-cost and cloud-calibrated technology innovations, offer new possibilities for large-scale, all-weather environmental data monitoring.

‘The significance of air quality big data lies in the fact that we no longer use a small number of sampling tests to estimate the overall situation. Instead, we directly conduct a panoramic tracking and investigation of the participants’ lives, which is equivalent to giving the public a more accurate perception of the air. The ability of quality.’ Zhang Lin, the research project sponsor and associate professor of electronic engineering at Tsinghua University, said that the original intention of his research was to encourage the society to use environmental data instead of emotional judgment to look at environmental issues. In addition, they also use the cloud calibration function to reduce the error of small sensors.

PM2.5 has become one of the important causes of high asthma

PM2.5 has become one of the important causes of high asthma

electric generator,ozone generator,chinese made generator

In recent years, the incidence of asthma has been on the rise, especially in children with increased incidence of asthma. Respiratory experts explain that this has a lot to do with the increasing air pollution in recent years, and PM2.5 is an important cause of high incidence of asthma.

Why is the prevalence of asthma high? Respiratory experts explain that this has a lot to do with the increasing air pollution in recent years, and PM2.5 is an important cause of high incidence of asthma. Especially in the continuous smog weather, the number of patients who came to see a doctor in the respiratory department of major hospitals increased significantly.

First, know asthma

Asthma is bronchial asthma, which is often referred to as ‘cracking disease’, ‘air urgency’ and ‘asthma disease’. It is the most common chronic non-specific inflammatory disease in the airway and is the most common chronic disease in the world. One.

The pathogenesis of chronic airway inflammation in asthma is complex, mainly related to allergic reactions and abnormalities in immune regulation. In a popular way, it is allergic or sensitive to the airway, resulting in recurrent cough, wheezing, difficulty breathing, chest tightness and other symptoms, mostly at night or in the early hours of the morning. These symptoms can be relieved by themselves or quickly relieved by treatment.

In addition to typical bronchial asthma, there is a special type of asthma that varies from cough, which is easily overlooked or misdiagnosed, namely ‘variable asthma.’ Its main symptoms are coughing only, paroxysmal and irritating dry cough at night, and patients usually have no obvious upper respiratory tract infections and fever before coughing, and are often misdiagnosed as bronchitis. If the child has a cold or cough, parents should be careful if they have asthma. Many parents mistakenly treat asthma as a cold and delay treatment.

Asthma and rhinitis are sisters

Pay attention to asthma and pay attention to allergic rhinitis. Allergic rhinitis is closely related to asthma. The survey found that 80% of asthma patients with allergic rhinitis, most asthma patients have asthma or simultaneous onset of rhinitis. Asthma and rhinitis belong to an airway, which is also a chronic inflammatory disease of the airway, thus supporting the idea that ‘one respiratory tract, one disease’ is a sister. Allergic rhinitis is also a risk factor for asthma, so early treatment of allergic rhinitis Can reduce the incidence of late asthma.

Second, how does smog induce asthma?

In addition to congenital genetic factors, the onset of asthma has a lot to do with the environment. Such as urban air pollution, home decoration, second-hand smoke, pets, carpeting, pollen, etc. can induce asthma. With the increase of urban air pollution, smog has become an important cause of high incidence of asthma.

A large amount of PM2.5 particles in the smog, the human nose and throat have been blocked, they can go down all the way into the bronchioles, alveoli, and then enter the capillaries through the alveolar wall, and then enter the entire blood circulation system. The most direct and most influential one is the damage to the respiratory system.

Sulfate, sulfur dioxide, heavy metals and various bacterial viruses carried in PM2.5 are easy to invade the human respiratory tract. A large amount of particulate matter enters the lungs and has a clogging effect on local tissues, which can reduce the ventilation of local bronchus, bronchioles and alveoli. The loss of ventilation function, particulate matter adsorbed by harmful gases can also stimulate or even corrode the alveolar wall. The most direct effect is that it is easy to cause respiratory tract irritation, poor breathing, chest tightness, dry cough, dry throat and itching, etc. Long-term inhalation is easy to cause rhinitis, pharyngitis, bronchitis and other diseases, and it is easy to cause chronic diseases such as asthma and chronic bronchitis. Acute attack.

Previously, a study in Hong Kong confirmed that the increase in air pollution was significantly associated with an increase in hospitalization rates in patients with allergic asthma. When the sulfur dioxide in the air increased to 10μg/m2, the relative risk of admission was 1.017. When the sulfur dioxide in the air increased by 10μg/m2, the proportion of acute allergic asthma hospitalization increased by 3.3%. Nitric oxide, ozone and atmospheric particulate matter can be used. Increasing the proportion of hospitalization for patients with allergic asthma increased by 5.5%, 5.9%, and 3.0%, respectively, suggesting that these four air pollutants are important factors in the aggravation of allergic asthma.

Third, how to prevent asthma in smog days

For people with a genetic history of asthma

1. Smog days to minimize going out or wearing a mask

When encountering dense fog weather, try to reduce your outing. If you have to go out, it is best to wear a professional anti-PM2.5 mask and try to use a version with a breathing valve. In addition to filtering some of the particles in the air, it can also warm the cold air and reduce the stimulation of the respiratory tract.

2. Determine allergens

To prevent asthma, first determine your body’s allergens. Dust mites, cats, dog skin scales, mold, pollen, milk, eggs, silk, feathers, moths, cotton wool, fungi, drugs, etc. are all important allergens. For patients with food-induced asthma attacks, first determine which food is allergic to it. You can go to the hospital for personal allergen testing.

3. Pay attention to climate change and prevent colds.

Winter and spring are the high incidence of asthma, the weather suddenly changes or the pressure is reduced, etc. Cold and cold and upper respiratory tract infection are the most common causes, so pay more attention to keep warm and prevent colds.

4. Pay attention to adjusting mood and avoid excessive fatigue.

Anxiety, sadness, over-excitement, and even laughter can also lead to asthma attacks. People who are psychologically vulnerable and have psychological barriers will feel abnormally heavy, nervous, and depressed in this weather. These people should pay attention to emotional regulation in the foggy days. You can listen to music and do something that you feel happy about. Maintain good exercise habits and daily routines, and don’t get too tired.

5. Drink plenty of water and eat more lungs and fruits and vegetables

For smoggy weather, choose a food that is lighter and rich in vitamins C and A. Eat more fresh vegetables and fruits such as spinach, tomatoes, carrots, oranges, grapes, kiwis, etc. Drinking plenty of water can also help the body to expel toxins.

6, cough, chest tightness, need medical attention

Children’s immune function is not perfect, it is more sensitive to external stimuli, and it is easy to cause asthma attacks in case of severe air pollution. Many children start to have cold symptoms at the beginning. Many parents think that their children only have a cold and don’t pay attention to it. When the acute episode comes to the hospital for treatment, it has often developed to the severity of breathing difficulties. Therefore, when the child has cough, chest tightness, sneezing, and spit white foam, the inhalation is relatively smooth, but you should seek medical advice if you have a bad breath. Otherwise, the terrible consequences of collapse may occur.

Have asthma in the family

1. Improve the living environment to avoid asthma

There are a large number of allergens in the living environment that can cause asthma attacks, such as dust mites and fungi. Therefore, it is necessary to improve the living environment and minimize the allergens. The bedroom should be simple, don’t hang fluffy jewelry, don’t put any good items such as carpets and fabric sofas, and don’t keep cats, dogs and other pets. Parents must not smoke.

Bed bedding should be exposed frequently, tapped, and washable bedding such as bedspreads, duvet covers, etc. should be cleaned frequently, and washed with hot water above 55 °C or even 100 °C to kill mites. If the economic conditions permit, the bedding should be replaced once every 2 to 5 years.

2. Adhere to the standard medication

Respiratory patients should insist on taking the medicine on time in the fog to avoid the disease. Pay attention to your body’s feelings and reactions, and seek medical advice if you feel unwell.

3. correct window ventilation

In the smoggy weather, avoid the traffic peaks in the morning and evening, and open the window twice a day for 20-40 minutes under static wind conditions. Increasing the humidity in the room, excessive drying in the room will increase the dust in the air.

4. In the diet, we must pay attention to the ‘six but not’ principle: eating should not be too salty, too sweet (chocolate), too greasy (animal fat), should not eat too much spicy, spicy and other foods, should not eat too much allergenic protein Food (milk, fish, seafood, etc.) should not be full.

5. Develop good habits, limit the amount of exercise, avoid overwork and mental stress, stimulation.

6.Install the air purifier

It is best to install an air purifier with PM2.5 particles in the home. It is good for removing PM2.5, and it can increase the relative humidity in the air and make it more comfortable to breathe.

First, PM2.5 is more harmful to patients with respiratory diseases

The most direct and most influential effect of PM2.5 on the human body is the damage to the respiratory system. Beginning in 2004, Pan Xiaochuan, a professor at the Peking University School of Medicine, began monitoring the daily average concentration of PM2.5 in the air. He found that the number of emergency patients in the nearby hospital respiratory system changed significantly as the value increased. Studies in previous years have shown that the number of patients with PM2.5 growth in hospitals with respiratory-related emergency-related diseases is positively correlated. For every 10 μg/m3 increase in PM2.5 daily average, the emergency volume is likely to increase by 0.5% to 1%.

The fine particles below PM2.5, the nose and throat of the human body can not stop, they can go down all the way into the bronchioles, alveoli, and then enter the capillaries through the alveolar wall, and then enter the entire blood circulation system.

PM2.5 is like a carrier that carries many harmful substances such as bacteria, carcinogens, polycyclic aromatic hydrocarbons, heavy metals, and so on. A large amount of particulate matter enters the lungs and has a clogging effect on local tissues, which can reduce the ventilation of local bronchus, loss of ventilation function of bronchioles and alveoli, and particulate matter adsorbing harmful gases can also stimulate or even corrode the alveolar wall. The most direct effect is that it is easy to cause irritation, cough, and difficulty breathing.

For patients with respiratory diseases themselves, inhaling excessive amounts of PM2.5 may result in decreased lung function, causing and aggravating asthma, rhinitis, and chronic bronchitis, which may cause lung sclerosis and toxic particles that remain in the alveoli. Eventually it will affect our epithelial tissue, inactivate the tumor suppressor gene, and induce lung cancer.

On October 17, 2013, the International Agency for Research on Cancer (IARC) at the meeting in Lyon had identified the atmospheric pollutant PM2.5 as a primary carcinogen (a definition of one level: a carcinogen for humans). At this point, in addition to affecting cardiovascular and respiratory diseases, PM2.5 will increase the risk of lung cancer.

Second, PM2.5 is more harmful to patients with cardiopulmonary disease

On February 20, 2013, a study published in the European Heart Journal showed that PM2.5 was positively associated with heart disease mortality. The higher the PM2.5 concentration, the higher the mortality rate of heart disease patients. . Patients with acute coronary syndromes will have an increased mortality rate if exposed to excessive 2.5 micron inhalable particulate matter in the air.

A previous US data study also confirmed the cardiovascular hazard of PM2.5. The study confirmed that for every 10 micrograms per cubic meter of PM2.5 daily increase, that is, for each 144 micrograms of PM2.5 inhalation (10 micrograms per cubic meter x 0.01 cubic meters x 60 minutes x 24 hours), the mortality rate of cardiopulmonary disease rises. 6% higher, lung cancer mortality increased by 8%.

When the PM2.5 content in the air increases, the absolute oxygen content decreases, and the amount of oxygen inhaled by the human body decreases. Because the pulmonary vesicles in the lungs are important parts of blood oxygen exchange, if the lungs are blocked by PM2.5 particles. , the function of exchanging oxygen with the pulmonary capillaries is reduced, and blood oxygen exchange is insufficient. The reduction of oxygen in the blood will cause a series of adaptive changes in the human body. Two prominent points, one is to ensure the oxygen supply of the human body, the blood flow will become faster in the blood vessel; the second is that the blood vessel membrane will become thicker, the blood vessel cavity will become narrower, and the risk of thrombosis will increase.

In addition to changes in the vascular membrane, many harmful substances carried by PM2.5, directly into the blood after inhalation, will directly damage the intima of the blood vessel, thereby thickening the vascular intima, causing stenosis, increasing blood pressure, etc., and increasing the thrombus. may. It even causes heart disease such as congestive heart failure and coronary artery disease.

In the haze days with high PM2.5 concentration, the sun is often blocked, the temperature is often low, some high blood pressure, coronary heart disease patients go from warm indoors to cold outside, the blood vessels expand and contract, and the blood pressure rises. high. The blood vessel wall of the elderly is very thin, and it is easy to cause stroke and myocardial infarction after the blood pressure is raised. In addition, upper respiratory tract infections caused by smog, pneumonia and other symptoms can easily induce heart failure in patients with heart disease, which can lead to shock or even death.

So, what protective measures should we take for such people?

What protective measures should be taken?

1.Try to reduce the door

Smog days should be minimized, or outdoor activities should be reduced. Try not to go to many places, such as supermarkets, shopping malls and hospitals. These places have poor air circulation and are prone to cross-infection of respiratory diseases. This type of group generally does not recommend wearing professional protective masks for a long time, because the masks of N90 and N95 series have large respiratory resistance, and there will be chest tightness and uncomfortable feeling after wearing. If you must wear it, you can consult a doctor first. At the same time, after going out, you should wash your face and bare skin immediately, or rinse your nose with water.

2.Tinstall air purifiers, plant green plants

It is best to install an air purifier with PM2.5 particles in the home. It is good for removing PM2.5, and it can increase the relative humidity in the air and make it more comfortable to breathe. For details on how to purchase an air purifier, please refer to the special content of my station.

Plants with relatively strong adsorption capacity can be planted in balconies, terraces, indoors, and large leaf plants can be selected as much as possible. Because of the large leaf area and many pores, it can not only adsorb PM2.5, but also increase the oxygen content of air. Such as green radish, evergreen, tiger skin, ivy and so on.

3.Do indoor cleaning

Such people spend more time indoors, pay special attention to cleanliness, wipe the tables and chairs with water in the house and mop the floor, because the humid air helps to reduce dust and fine particles floating in the air. In addition, the use of a humidifier, the placement of towels on the heater, the cleaning of sheets, pillows, etc. with a wet towel are all desirable methods of absorbing fine dust. In addition, use as little as possible air cleaning agents or insecticides, including aldehydes, benzenes and other pollutants.

Bed bedding should be exposed frequently, tapped, and washable bedding such as bedspreads, duvet covers, etc. should be cleaned frequently, and washed with hot water above 55 °C or even 100 °C to kill mites. If the economic conditions permit, the bedding should be replaced once every 2 to 5 years.

4.Light diet

In the diet, we must pay attention to the ‘six but not’ principle: eating should not be too salty, too sweet (chocolate), too greasy (animal fat), should not eat too much spicy, spicy food, etc., should not eat too much allergic protein food ( Milk, fish, seafood, etc.), should not be full.

Drink plenty of water, pay attention to light diet, use cold, steamed, boiled, marinated, etc. instead of fried, fried, fried. Eat more foods rich in vitamin C, vitamin A, protein and other nutrients to enhance their resistance.

5.Pay attention to adjust mood, avoid excessive fatigue

Anxiety, sadness, over-excitement, and even laughter can also lead to cardiovascular disease. People who are psychologically vulnerable and have psychological barriers will feel abnormally heavy, nervous, and depressed in this weather. These people should pay attention to emotional regulation in the foggy days. You can listen to music and do something that you feel happy about. It is necessary to maintain a scientific law of life, avoid overwork, ensure adequate sleep, and reduce psychological stress.

How much influence does smog have on sensitive people and how to prevent it?

How much influence does smog have on sensitive people and how to prevent it?

Studies have shown that increased incidence of allergies is closely related to air pollution. In smog, an increase in the concentration of PM2.5 in the air can cause various allergic diseases such as allergic rhinitis, asthma, eczema, erythema, itching, and diarrhea. So, how can sensitive people prevent allergies in the haze?

First, what is sensitive physique

Generally, people who are prone to allergic reactions and allergic diseases and cannot find the cause of the disease are called ‘sensitive physiques’. People with ‘sensitive physique’ can develop various allergic reactions and allergic diseases, such as allergic rhinitis, bronchial asthma, cough symptoms, itchy eyes or redness in the respiratory system; wind rash, eczema, angioedema, Red spots, itching phenomenon; digestive system may cause abdominal pain, nausea, vomiting, diarrhea, gastrointestinal bleeding, oropharyngeal itching, foreign body sensation and other discomfort.

Second, the cause of sensitive physique

The causes of sensitive physique can be divided into two categories, internal and external. The internal cause is mainly derived from the history of family allergic diseases, often caused by parents and lack of immune function of the body at birth; the external causes of sensitive physique are complex and diverse, mainly including food, drugs, cosmetics, chemicals, Pollen, pets, bacteria, air pollution, etc.

Third, the cause of the disease caused by sensitive constitution

The latest research shows that the formation of sensitive physique, as well as the onset of allergies, are related to the ‘healthy killer’ in the body – excessive accumulation of free radicals. The number of free radicals in allergic people is much higher than that of non-allergic people. Increasingly serious environmental pollution, chemical abuse and radiation problems will directly cause the accumulation of free radicals in the body.

Free radicals come from two sources: one is constantly produced in the body’s own oxidative metabolism; the other is environmental pollution, radiation, bad habits, etc., and will continue to generate free radicals. Free radicals can be called the source of all evils. The aging of the human body and the production of many diseases are closely related to it.

Free radicals form lipid peroxides that can damage biofilms, destroy cells, impede normal metabolism, accelerate aging, and cause such imbalances, allergies, refractory dermatitis, rhinitis, conjunctivitis, asthma, eczema, and myocardial infarction , gout, nephritis, cataracts and other diseases.

Fourth, the impact of air pollution on sensitive physical groups

Among many external factors, allergic diseases caused by air pollution account for a considerable proportion. Many studies have shown that increased incidence of allergies is closely related to air pollution. Increased concentrations of ozone and nitrogen oxides in the air can cause bronchoconstriction and decreased lung function, leading to allergic respiratory diseases such as allergic rhinitis and bronchial asthma.

PM2.5 is like a carrier that carries many harmful substances, such as bacteria, dust, heavy metals, etc., and when it enters the human body through the respiratory tract, the free radicals in the body will increase dramatically. Under normal circumstances, amino acids, vitamins and enzymes in the body can remove excess free radicals. However, in the case of high concentration of smog for a long time, a large amount of particulate matter is absorbed by the body, and free radicals in the body are increased, which cannot be removed in time, and will directly oxidize the human body. The mast cells and basophils cause the cell membrane to rupture and release histamine, which produces an allergic reaction. Therefore, improving the allergy will eliminate free radicals.

Pregnant women living in areas with severe air pollution for a long time are prone to low birth weight. Low birth weight is associated with a series of serious health problems, including postpartum imperfections, low immunity, heart and respiratory diseases, etc. One of the causes of allergies.

Five, how to prevent allergies

1.Go out wearing a mask

People with sensitive physique should wear masks when they go out, especially in foggy weather. You should choose a professional PM2.5 protective mask to minimize the crowds and plants and flowers to avoid contact with allergens.

2.The daily diet should be balanced

People with allergic physique should pay special attention to diet, try to eat less processed or refined, greasy, spicy food, and eat less sweets, these foods may aggravate allergic symptoms. Eat more foods containing vitamins A and C, which can scavenge free radicals and enhance the body’s immunity. Cabbage and citrus can resist allergies and should be eaten in daily life. Eat more calorie foods, you must not eat cold food.

3.To have good living habits

Wash your face and brush your teeth with hot water and change your laundry frequently. Keep the room clean, bedding and bed sheets should be washed frequently. Reduce outdoor activity time in the spring to prevent allergies to pollen. It is not advisable to keep pets and avoid contact with allergens from everyday life.

4.Exercise, enhance resistance

The living should be regular, do some physical exercise, relax and avoid emotional stress. Combined with the medicated diet to enhance immunity, it has a significant effect on improving allergic constitution.

5.The correct choice of skin care products

Allergic skin is extremely sensitive, so be careful when choosing skin care products. Do not use products that contain spices, alcohol, and fruit acids, which are irritating to the skin and cause allergies.

6.Use an air purifier

The air purifier helps to filter out all kinds of harmful substances and protect your health!

The elegant Paris also began to fall into the smog. After several days of air pollution, the French Prime Minister’s decision was to ‘oxygenate’ the city with a short-term traffic control policy.

Specifically, it includes: regional express trains in the Paris Region, subways, buses, bicycle rentals, etc., which will be used free of charge by the public; the three provinces in Paris and its surrounding provinces implement the restrictions on single and double numbers of motor vehicles. The limited line applies a small amount of 22 euros; it is forbidden to carry more than 3.5 tons of trucks and light vehicles without carburetor, and so on. Of course, the policy does not restrict the use of environmentally-friendly vehicles such as electric vehicles and natural gas vehicles, nor does it prohibit private vehicles that carry at least three people to encourage carpooling, while medical, fire-fighting, and food supply support the functioning of the city. Cars are not subject to this limitation.

In the days when only ‘Running can feel the wind’, suddenly the ‘running on the road’ was not allowed, and many French people felt inconvenient. The most intuitive role of car restrictions is to reduce vehicle emissions, but whether it can alleviate the smog in Paris is still controversial. In 1997, Paris also tried car restrictions, and the city air testing agency also used the remarkable effect of that time as a strong basis for this policy. Most Parisians also accept and comply with the government’s interim policy. In very days, I am afraid that no one will overestimate the attempts to protect public health, and once the weather is clear, some issues still need to be clarified and answered. For example, how big is the ‘contribution rate’ of automobile exhaust to smog? Will the limit line be the best choice for Paris? Is the timing of the restriction policy appropriate?

The same people who care about the ‘experience’ of Paris are those who are under the pressure of atmospheric pollution. They are also asking themselves, ‘What if I am?’ The answers often have common characteristics and case significance.
