Smoking has become the patent of most men, like a habit, no matter where you have time, you want to smoke one. And we all know that smoking is harmful to health, but we must tell you that second-hand smoke is more harmful. Second-hand smoke, also known as passive smoking and environmental tobacco smoke, refers to a mixture of smoke released by the burning end of cigarettes or other tobacco products and smoked by smokers. It is also the most widespread and serious indoor air pollution, and it is the leading cause of death worldwide. Studies have pointed out that second-hand smoke has more than 4,000 kinds of harmful chemicals and dozens of carcinogens such as tar, ammonia, nicotine, aerosols, PM2.5, and strontium-210.

Especially those who have smoked for a long time, people who have not quit smoking, or people who have become accustomed to smoking. Whether you are at home or at work, you can smoke without moving. The smoke in the house or office is full of smoke, as if in the fairy world. Second-hand smoke in a full house, whether it is your family, a colleague, or your own second-hand smoke, is more harmful to your health. Second-hand smoke is no less harmful to passive smokers than active smokers, especially for children and young people. According to the survey, in China, the main victims of passive smoking are women and children. Although they do not smoke themselves, they often suffer second-hand smoke from others in their homes and public places.

One experiment: in a smoking room of 120 square meters, 6 people smoked. In 30 minutes, the average concentration of PM2.5 in the smoking room was 737.62 micrograms per cubic meter, which was 67 times higher than that of the national air quality standard. A safety value that goes far beyond human health. This experiment proves that if someone smokes indoors, even if they use ventilation or set up any type of smoking area indoors, they can’t reach the requirement of full smoke-free. Second-hand smoke does not have the so-called ‘safe exposure’ level.

So, you smoked yourself and don’t go to harm your family. Recognize the dangers of second-hand smoke from family members?

How much do you know about the hazards of PM2.5?

How much do you know about the hazards of PM2.5?

air purifier hepa,air purifier hepa filter,uv air sterilizer

With the frequent smog and PM2.5 vocabulary in the network and media reports, I believe many people are no strangers to PM2.5, but how much do you know about the real harm of PM2.5? In addition to knowing that it can cause respiratory diseases such as cough and asthma, do you know that it may even damage the reproductive system and affect fetal development?

1.The respiratory system

As we all know, PM2.5 is the most direct and most influential to the human body. 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. We can imagine that the sand in the eyes and the eyes will be inflamed. Deep in the respiratory system is also a sensitive environment. Fine particulate matter stays in the respiratory system as a foreign body for a long time, which also causes inflammation of the respiratory system. Causes cough, difficulty breathing, rhinitis, rhinitis, exacerbation of asthma, and chronic bronchitis.

2.Cardiovascular system

PM2.5 enters the lungs through the respiratory system, and 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.

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%.

3.Affecting fetal development caused by defects

A survey from northern Bohemia conducted a study of pregnant women exposed to high concentrations of PM2.5 and found that high concentrations of fine particulate contaminants may affect fetal development. PM2.5 is attached with many harmful substances such as heavy metals and polycyclic aromatic hydrocarbons, which cause maternal blood toxicity, which may lead to intrauterine growth retardation and low birth weight, as well as congenital functional defects. Toxic substances can also pass through the placenta and directly poison the fetus. Premature infants, neonatal mortality, especially in early pregnancy.

An article published in the US Environmental Health Outlook magazine shows that researchers at the University of California analyzed the birth weight of more than 3 million newborns in 14 regions of nine countries and found that pregnant women living in areas with severe air pollution are prone to low birth weight ( Low birth weight infants refer to infants weighing less than 2.5 kg at birth). The higher the degree of airborne particle contamination, the higher the chance that a pregnant woman will give birth to a low birth weight. For every 10 micrograms per cubic meter of PM2.5 concentration, the birth weight of newborns is reduced by 8.9 grams, and the chance of becoming a low birth weight is increased by 3%.

Low birth weight is associated with a range of serious health problems, including postpartum imperfections, premature death, heart disease, affecting brain development, childhood asthma, and decreased lung function in adulthood.


Inhalation of excessive PM2.5 can lead to decreased lung function, triggering and aggravating asthma, rhinitis, chronic bronchitis, and severe lung sclerosis, toxic particles that remain in the alveoli, which will eventually affect our epithelial tissue and cause tumor suppressor genes. Inactivated, induced 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.

5.Hurt the skin

The skin is the largest organ in the body, communicating with the outside world through breathing. Because it is exposed to the air for the longest time and the largest area, there is a certain amount of damage when exposed to smog for a long time.

PM2.5 adsorbs harmful substances such as heavy metals and microorganisms. When these particles are stained on the skin, they will cause irritation to the skin and hinder the normal breathing and detoxification of the skin. Staying in the skin for a long time will clog the pores, and the skin will become dull and rough, causing skin conditions such as acne, acne, itching, and severe skin diseases such as dermatitis, eczema and urticaria. Therefore, the continuous smog weather for many days is also an important reason for the increase in the number of hospital dermatology clinics.

6.Triggering mental illness

Most people may have such experiences. They feel comfortable and energetic in sunny weather, while in the rainy weather they feel depressed and unable to do spiritual work.

The haze weather is low and the visibility is poor. It is easy to cause people to be lazy and depressed. The impurities in the air cause people to have difficulty breathing and chest tightness. These bad symptoms also affect mental health. The inconvenience of travel can cause people to suffer depression, psychological quality is poor, patients with obsessive-compulsive disorder, physical disorders and suspected illnesses are prone to psychological problems. In addition, the lack of sun exposure in the haze days, the body’s happy hormone melatonin is contained, so people are prone to seasonal mood disorders and even induce depression.

Melatonin has an inhibitory effect on life activities, causing depression, lowering body temperature, slowing heartbeat, and lowering blood pressure. At this time, the brain and the body will enter the rest state and start the sleep mode. As the sun exposure time in the autumn and winter seasons is gradually shortened, the melatonin content in the human body increases, causing the concentration of excitatory transmitters in the body to decrease, the excitability to decrease, and causing a depressed emotional response. Therefore, patients with depression are prone to morbidity, and many people in the normal population will experience depression.

Why buy an air purifier for your child?

Why buy an air purifier for your child?

air purifier machine,air purifier hepa filter,air purifier odor eliminator

Does your child’s child often have a cold and cough? The highest incidence of children aged 0-14 years is respiratory diseases, such as respiratory infections, pneumonia, bronchitis, etc., accounting for 51.87%.

Why is the incidence of respiratory diseases in children so high?

This is due to the direct communication between the respiratory tract and the outside world. In addition, the children’s respiratory tract and immune function are insufficiency, and the body’s resistance is low, so the incidence of respiratory diseases is the highest.

In the indoor environment, which pollution has the greatest impact on children’s health?

  1. Second-hand smoke (38.30%)

Second-hand smoke has more than 4,000 kinds of harmful chemicals and dozens of carcinogens such as tar, ammonia, nicotine, aerosols, PM2.5, and strontium-210, which can cause asthma, pneumonia, lung cancer, and high blood pressure.

  1. There have been renovations in the family within three years (30.11%)

The attention pollutants for decoration are formaldehyde, followed by some volatile organic compounds. Formaldehyde has been identified as a carcinogenic and teratogenic substance by the World Health Organization, and children are expected to develop leukemia in an environment containing formaldehyde.

  1. Cooking does not use exhaust fan (23.50%)

The cooking fumes are classified into two types, particulate matter and gaseous pollutants, including various aldehydes, polycyclic aromatic hydrocarbons, etc., which easily damage the lungs and even induce lung cancer.

At present, it has been found that the air purifier can effectively reduce the number of colonies in the air in the maternal and child wards, and can also significantly reduce the content of dust mite allergies in the air. For allergic diseases such as asthma and rhinitis, air purifiers have a good preventive effect. Therefore, the purchase of an air purifier at home is very helpful for children’s respiratory health.

What do you know about indoor air pollution? What role does the air purifier play?

What do you know about indoor air pollution? What role does the air purifier play?

air purifier hepa filter,negative ion generator,air purifier

Under the ravages of indoor air pollution, more and more indoor air problems have been reported by the media. The respiratory health problems of the whole people are at the forefront. People are paying attention to indoor air quality safety and recognizing the importance of health and the environment.

So, what are the indoor air pollution?

1.Organic pollutants

First, formaldehyde is mainly derived from building materials, furniture, various adhesive coatings and synthetic fabrics. Among them, mainly from wood-based panels. Formaldehyde is a volatile organic compound that has a strong pungent odor.

Second, the benzene and benzene series toluene and xylene are colorless and aromatic, and are present in the vapor state in the air. In the interior decoration, due to improper selection of decoration materials or unreasonable construction process, it is easy to form indoor benzene and benzene-based pollution.

Third, volatile organic compounds (VOCs) are mainly derived from interior materials, fuels, and the like.

2.Inorganic pollutants

First, heavy metals, heavy metals in the air are present in atmospheric particulates, while atmospheric particulates with a particle size of less than 10um contain high levels of heavy metals.

Second, gaseous inorganic pollutants have a strong pungent odor and are highly soluble in water, mainly from additives and brighteners in interior decorative materials.

3.Biological pollution

Biological pollution is mainly caused by the moisture and mildew walls in the living room, domestic garbage, pets, indoor flowers, carpets, air conditioners, furniture, etc. The main pollutants are bacteria and germs.

What are the hazards of indoor air pollution to the human body?

1.Causing frequent respiratory diseases

Indoor air pollution can lead to acute and chronic changes in lung function, which can increase the filtration of respiratory symptoms, such as bronchitis and asthma.

2.Increase allergic diseases

A common symptom is allergic rhinitis. The most serious allergic disease caused by allergens and stimuli in the air is allergic asthma, which can be caused by allergens or irritants in indoor air pollutants.

3.Carcinogenic effects

Smoke, cockroaches, polycyclic aromatic hydrocarbons, asbestos, benzene and formaldehyde, and certain insecticides all have carcinogenic effects. Although the true hazard to human health is not clear, there is a potential hazard, so their concentration should be minimized in indoor air.

4.Poisoning the central nervous system

It is well known that nerve cells of the central nervous system do not have the ability to regenerate, and usually toxic damage is irreversible. Therefore, harmful substances such as formaldehyde and smog are more harmful to the central nervous system than most other tissues.

5.Endangering cardiovascular and cerebrovascular

Indoor harmful gases such as second-hand smoke and carbon monoxide can cause cardiovascular symptoms and cardiovascular diseases, leading to increased morbidity and mortality of cardiovascular diseases.

How to avoid the danger of indoor air pollution?

1.Decoration choice of environmentally friendly materials

Those who are preparing to decorate new houses pay attention to the environmental protection of interior decoration materials, because a considerable part of indoor environmental pollution is caused by improper materials used in the decoration process, such as inferior fiberboard, plywood, paint, paint, adhesive, furniture, carpet, etc. A large amount of organic gas pollutants will be released. Therefore, in the decoration process, try to use formaldehyde-free viscose, benzene-free thinner, formaldehyde-free large core board, veneer, etc., to improve the indoor air quality level after renovation.

2.Often open window ventilation

Frequent ventilation and ventilation are the most economical way to prevent indoor environmental pollution. Regardless of whether there is anyone in the house, it should be ventilated as much as possible. On the one hand, it is conducive to the discharge of indoor pollutants, and on the other hand, the toxic and harmful gases in the decoration materials can be released as soon as possible.

3.Using an air purifier

Selecting an effective indoor air purification facility, air purification devices with different functions, such as air purifiers, can be selected according to different pollutions of living room, kitchen and sanitation. The air purifier promotes the circulation of air through the ventilation system, and the air to be filtered flows into the 3-4 layer filter from the air inlet, adsorbs and decomposes the formaldehyde molecules in the air, and reduces the pollutants in the air through continuous circulation. Finally, the purpose of purifying the air is achieved.

4.Maintain a certain humidity and temperature in the indoor environment

Humidity and temperature are too high, most of the pollutants are emitted from the decoration materials quickly, which is disadvantageous when there is a person indoors, and the humidity is too high, which is beneficial to the proliferation of microorganisms such as bacteria. However, when there is no one in the house, for example, when taking a trip, some measures can be taken to increase the humidity.

In summary, indoor pollutants are diverse and can cause harm to various organs of the human body. For health, we try to choose ventilation. When it is not convenient to ventilate, we can use air purifier to remove indoor pollution and improve indoor air quality. To ensure quality of life.
