In the spring season in northern regions, it's common to experience widespread fog or dust. In recent years, pollution has continued to rise across the country, and even many southern cities have faced severe smog problems. Children’s respiratory systems are delicate and more vulnerable to dust and pollutants. Fog and pollution have now become essential topics for parents to understand and manage.
Originally, fog and haze were natural weather phenomena with no human involvement. However, over the past few decades, the increasing number of low-pressure systems in central and eastern China is largely due to human activities, such as the emission of atmospheric particulates. Today, when smog has become a daily concern, both fog and haze are influenced by human actions, no longer purely natural occurrences.
According to the Beijing Environmental Protection Bureau, three main factors contribute to severe air pollution: extreme weather conditions, high levels of pollutant emissions, and the regional transmission of PM2.5. This situation is not unique to Beijing; similar issues occur in other cities, often linked to industrial growth and increased emissions.
PM1 particles, which are smaller than 1 micrometer in diameter, consist of organic carbon, sulfate, and nitrate aerosols. Sulfate mainly comes from coal-fired power plants and heating, especially in northern areas, while nitrates also stem from vehicle exhaust.
The saying “spring willow fluff, summer wheat straw, autumn dust storms, and winter fog†reflects the seasonal challenges. Ensuring children's health in such conditions has become a major concern for mothers.
During spring, especially on windy days, willow fluff, catkins, and pollen can cause serious issues, particularly for allergic children. These irritants may lead to coughing, sneezing, and nasal inflammation. Some kids might experience facial itching or discomfort if they inhale these particles. Prolonged exposure can cause dryness and swelling in their throats, making outdoor activities even riskier.
On days with little wind, smog, dust, and sand have become new threats. The presence of fine particulate matter in the air can make breathing uncomfortable for adults, and even more dangerous for children, potentially causing allergies and respiratory issues.
To protect children, wearing a mask is one of the most effective measures. On hazy days or during pollen season, it's best to limit outdoor activities. However, since children love playing outside, masks should be worn whenever they go out. Regular masks offer limited protection against PM2.5, while professional masks provide better defense for young, developing respiratory systems.
Currently, China lacks a unified standard for civilian masks. N95 and N99 masks are designed for dust and bacteria protection, with N95 offering 95% efficiency against 0.3-micron particles, and N99 offering 99%. For children, choosing an N99 mask is ideal, as it offers strong protection against various pollutants.
Standard masks like medical or disposable ones can restrict airflow, making breathing difficult. This is especially problematic for children, whose hearts and lungs are still developing. Wearing such masks may lead to shortness of breath and affect their normal development. Some brands now offer masks with ventilation valves for easier breathing, tailored for children.
Additionally, encouraging children to eat more fresh vegetables can help protect them from pollution. While vegetables don’t detoxify, they contain antioxidants like vitamin C and flavonoids that support the body’s defenses. Drinking enough water is also important, as it helps keep the respiratory tract moist and reduces discomfort.
In conclusion, to ensure children's safety in polluted environments, investing in a professional mask is essential. It provides the best protection for their sensitive respiratory systems.
