How can the trouble of "wutong catkins" be broken in the season of "everyone's body is hairy"?
2023-04-28
If you see me on the road, please don't misunderstand me. It's just because wutong catkins are flying into your mouth again. As spring gradually deepens, there are also many friends around who frequently sneeze and have a runny nose. After asking, we learned that it was the season when the wutong tree on the street began to fly... Experts from Wuhan No.4 Hospital provided the following reference for friends who were troubled by flying catkins during this period. The wutong tree with flying catkins is called "Platanus acerifolia", the greening tree species selected by domestic cities. In the north, poplar and willow trees are mainly used, and in the south, wutong and kapok are mainly used. Wuhan, which is neither south nor north, is mainly wutong, and a few areas have poplar and willow trees. Speaking of not too cold knowledge, the wutong tree you saw in Wuhan is called "Erqiu Platanus", which is commonly known as "French wutong". It is an imported variety, and it is different from the one in "wutong is also a drizzle". This thing grows fast, has strong shade, is durable and has a long lifespan... As a city street tree, it is almost perfect, and the only problem is flying catkins. There are two main sources of wutong catkins. One is the bud catkins falling off from the new leaves of wutong trees in the recent period. After the fruit ripens in May, a large amount of needle like flocs will be produced after the fruit ball ruptures. The expert once went to school in a school famous for "wutong rain", and after graduation, he lived in a street famous for wutong trees for a long time. He was very impressed with this thing. Compared with "clusters" of wutong catkins, willow catkins are "lumps", look more like cotton, and are more likely to be blown by the wind. Flying catkins themselves are not "toxic", but the three major hazards cannot be avoided. There have been many roast about flying catkins on social networks. I won't talk much about topics related to landscape technology and urban construction. Let's continue talking about health. Fei Xu itself does not have any so-called "toxicity", but they may be coated with various pollen, bacteria, fungi, dust, etc. during the flying process, and their impact on human health mainly includes the following aspects: ◎ Respiratory symptoms In the original novel of "The Legend of Zhen Huan", the emperor's cousin and favorite concubine Hu Yunrong died of severe asthma caused by Liu Xu under the design of Zhen Huan. Although it is the plot of a literary work, plant catkins can indeed cause greater distress for groups such as allergic individuals and asthma patients. Small flying particles carrying allergens can easily enter the respiratory tract, causing symptoms such as allergic rhinitis, sneezing, runny nose, respiratory edema, and even difficulty breathing. Considering that many people still have the habit of wearing masks, the probability of flying feathers entering the respiratory tract has been significantly reduced due to eye redness and swelling. However, most people do not wear goggles when they are free. Once flying catkins enter the eyes, improper handling may damage the cornea. Some allergic individuals may also develop allergic conjunctivitis, which may even affect their vision. Additionally, rubbing the eyes with unclean hands may further irritate the eyes and worsen the symptoms. After flying catkins enter the eyes, it is best to lower your head and close your eyes, let the flying catkins flow out with tears, or rinse with water. If you still feel unwell, seek medical attention in a timely manner. Some classmates said that I am afraid of allergies and have my goggles fixed. But recently, the weather has become increasingly hot, and the skin exposure of daily clothing has increased
