Since last winter, Shandong has seen a number of hazy weather, which has affected people’s travel and health to varying degrees. So, in daily life, hazy days on human health and what is the impact? Haze is a large amount of dust, smoke particles, salt powder and other impurities floating in the air near the ground layer of air, once inhaled from the respiratory tract, will be deposited in the human alveoli, alveolar deposition of dust and smoke is dissolved into the bloodstream, which can easily cause blood poisoning. The undissolved part is absorbed by the cells and easily destroys the cells causing pneumoconiosis. Other harmful substances contained in the haze such as sulfur dioxide mainly stimulate the human respiratory tract, which is more harmful to people. When the haze is severe, the pollutant impurities within it can make people’s central nervous system lesions, cause pulmonary edema or chronic bronchitis, especially when people inhale into the lungs, which can lead to emphysema and lung cancer in severe cases. Jinan City Hospital of Traditional Chinese Medicine Otorhinolaryngology Shao Jianmin “air pollution is more terrible than SARS” —- Zhong Nanshan Of course the human body itself has the first line of defense against air pollution —– nasal mucosa. Nasal mucosa can effectively filter particulate matter in the airflow under the condition of maintaining its own certain humidity and temperature, and respiratory cilia can also run mucus, particulate matter, bacteria and so on. So due to the combined effect of the cilia clearance system as well as the immune system. Under normal circumstances, a sterile environment can be maintained. Then we as otolaryngologists should give you more effective care – “Huanglian oil”, the hospital’s ace of the topical self-preparation, pure traditional Chinese medicine preparations, it is our nasal mucosa to play, warming, humidification, moisturizing effect, to maintain the nasal mucosa of the relatively sterile The nasal mucosa is maintained in a relatively sterile environment. When we return home, we can touch Huanglian oil to our nose to increase humidity and relieve dryness. When we go out, we use Huanglian oil to resist dust, smoke particles, salt powder and other impurities in the outdoor air. Always maintain the normal function of the nasal mucosa, to play his best role. And it is easy to carry, good sense of medicine, no side effects. It can effectively resist the hazy weather.
