Spring haze serious child essential anti-mite mask

When the spring in the north falls, it is often accompanied by large areas of fog or dust. In recent years, pollution has increased unabated throughout the country, and many southern cities have also experienced severe haze. The child's respiratory system is fragile and is more vulnerable to dust and pollution. Mist and pollution have become topics that mothers need to understand.

Haze and pollution

Fog and haze were a kind of weather phenomenon at the beginning of their birth. There was no human intervention.

However, the significant increase in the number of east-central depressions in China in the last two or three decades is mainly due to anthropogenic emissions of atmospheric aerosols. Today, when haze has become a daily topic, no matter whether it is embarrassment or fog, it may not be able to escape the influence of human activities behind it. It is no longer a "natural" phenomenon.

The Beijing Environmental Protection Bureau has publicly stated that extreme adverse weather conditions, large pollutant emissions, and PM2.5 regional transmission are three major causes of heavy air pollution in Beijing. With the exception of the other cities where the smog phenomenon in Beijing is more serious, it can basically be attributed as such. In China, where industrial production is increasing, "pollutant discharge" is probably the most intuitive factor.

From the point of view of contaminants, PM1 in all regions contains PM1 (particles less than 1 μm in diameter). The components of PM1 include: organic carbon aerosols, sulfate aerosols, and nitrate aerosols. Among them, sulfate aerosols mainly come from coal-fired power generation and heating (especially in the north) of various parts of the country, and nitrate aerosols, in addition to the effects of coal combustion, also contribute to the contribution of motor vehicle fuel.

“Spring willow catkins, wheat straw in the summer, dust storms in autumn, and winter fog”, how children's health is guaranteed under this air condition has become a problem for every mother.

In the spring of the north, especially in windy weather, Yang Xu, catkins, and pollen have become nightmares for all kinds of people, especially allergies. For children, these stimuli are particularly susceptible to coughing, sneezing, rhinitis, and the like. Some children may have facial itching or even soreness due to catkins, pollen, and other irritations. If they inadvertently inhale into the nose or mouth, they may experience strong discomfort. In a long period of life in a lot of catkins, children's throat is easy to dry, red and swollen, for children who like outdoor activities, this phenomenon is even more vigilant.

In the days when there is no wind and wind, the haze, fog, dust, and sand have become new threats. A large amount of particulate matter is floating in the air, and even adults can feel uncomfortable to breathe. Seriously, they can also cause allergies and some respiratory diseases. Children are even more dangerous.

Choose a mask

In such hazy days, what are we to prevent flooding, dust, and allergy prevention measures to protect our children?—The most important thing is to wear a mask.

In bad haze days and catkins, try to avoid children's outdoor activities. But children love to play in nature, and they always have to be in the room. When you go out to play, pay attention to wearing a mask. General masks have little effect in protecting PM2.5, and can only do superficial exercises to protect children's respiratory system. Growing children and young children should purchase professional protective masks to prevent PM2.5 and other pollutants from harming the immature respiratory tract. Professional masks are slightly more expensive than regular masks, but they have significant effects in protecting various types of pollutants and pollen. For immature children, professional masks have become the only viable option.

At present, China does not have the prevailing standard for civil masks. N95 and N99 masks are special masks for protecting against dust bacteria and other harmful substances. N95 masks have a 95% efficiency for particles with a size of 0.3 microns and N99 masks with 99%. Masks are divided into a variety of styles, taking into account the protective effect of PM2.5 and PM1, mothers should try to choose N99 standard masks. Such masks can provide good protection even for adults. For children, this kind of good basic protection is a must.

General masks, such as medical masks, disposable masks, and silicone masks, will block air flow to a certain extent and cause poor breathing. Such masks are not suitable for sports wear and are not suitable for manual workers. The children's heart and lungs are not fully developed, and their breathing ability is even worse. Common masks will make them feel short of breath and breathless, but they may feel slightly uncomfortable, and they may increase the burden on the heart and lungs and affect the normal development of the respiratory system. It is reported that some brands of masks have been provided with air valves to ensure smooth breathing and have been designed to suit children and children.

In addition, allowing children to eat more fresh vegetables can play a protective role from the diet. The reason is not that vegetables can detoxify, but vegetables contain vitamin C and flavonoids and other antioxidants that help the body fight pollutant damage. Fruits and vegetables are already very healthy foods for children. There is "drink more water." Dry respiratory tract can increase children's discomfort, and urge children to replenish water at an appropriate time, which is an obligation for mothers.

To sum up, in order to protect children, it is necessary to purchase professional masks.
