Every year in April and May, many areas in the north will appear flying white silk. Some people think that this is the romance of spring and summer, and for people who are prone to allergies, flying in the sky is like a disaster.
In addition to letting you go out and being "pasted", what other health risks are there? Life Times (search for "LT0385" in WeChat to follow) interviews experts to save you surrounded by flying feathers.

How "dirty" is the flying feather?
Flying feathers are mainly plants of willow family, elm family, birch family, cypress family, pine family and other plants. The flying feathers in the sky are all from female strains.
These "flocs" are seeds, which are spread out with the help of wind and insects to complete reproduction. Flying feathers are distinctly seasonal and cyclical, and are a harmless natural phenomenon in themselves.
But in this white "hair", in addition to fibers and pollen, there are dust, bacteria, fungi and so on in the air.
The city is lined with high-rise buildings, and the space between buildings will form a microclimate, and the flying feathers will spin in such a "whirlpool", floating and falling.
In addition, the urban road network is encrypted, the green space is relatively reduced, and the ability to retain flying feathers is reduced, making it difficult to deposit on the ground, and the flying feathers have become very "difficult".
Flying feathers bring 4 health problems
There is a "flying season" in both the north and the south. In the north, most of the flying feathers last from April to mid-May, mainly willow feathers, while in Nanjing, from April to June, the autumn fruits of the tung trees mature and crack, forming a "drizzle rain".
Some people cause allergic reactions after inhaling the fly feathers, and have symptoms such as sneezing and runny nose, mainly because of the pollen, dust, etc. contained in the fly feathers, which have nothing to do with the fly feathers themselves.
But excessive flying feathers do have a certain impact on people with allergies.
Respiratory symptoms
The elderly, children and people who originally suffer from respiratory diseases react particularly strongly to Yang Shu and Sycamore Tidbits, and there will be symptoms such as itching in the nasal cavity and throat area, continuous sneezing, runny nose, respiratory edema, and difficulty breathing.
The eyes are red and swollen
Flying feathers may make the eyes red, swollen and itchy. Do not rub your eyes with your hands after developing allergy symptoms.
The skin of the unpasted hands may be stained with allergens such as pollen and insect mites, which will cause more and more itchy rubbing, aggravating irritation and redness.
Itchy skin
Itchy skin after contact with Yang Shu is a physical irritation, not an allergic reaction.
If it only shows itchy skin, no rash, scratches or wheals after scratching, it may be artificial urticaria, which is not related to allergies, and it is necessary to go to the dermatology department of the local hospital as soon as possible.
Security risks
The accumulation of yang and willow silk may also bring safety hazards. Once the willows flying around are ignited, the fire will spread rapidly.
To demonstrate the dangers of willow burning, firefighters did an experiment:

Firefighters remind that you must not light willows. When parking vehicles, it is necessary to clean up the willow wool and surrounding combustibles in time.
Wu Zunyou, chief expert in epidemiology at the Chinese Center for Disease Control and Prevention, made it clear that in more than two years of research, no flying feathers have been found to adsorb the new crown virus, and there have been no reports of infections caused by flying feathers so far.
Allergy-prone physique 4 tricks anti-flying feathers
Everyone wears a mask during the epidemic period, which can help avoid the "invasion" of flying feathers. In addition to going out to do a good job of protection, in the flying season, experts remind people who are prone to allergies to pay attention to the following points:
1
Don't go out during high-incidence periods
When the weather is clear, generally 10:00 to 16:00 is the high incidence of flying. People with allergies should try to avoid going out at this time.
When going out, you should wear a mask, protective goggles, scarf, etc.; wash your face in time after returning home, rinse your nasal cavity, change your clothes, and the clothes you wear outside can be hung on the porch or entrance, and do not bring them into the bedroom.
2
No need to rub your eyes and nose with your hands
Flying feathers into the eyes bring discomfort, many people will not be able to resist rubbing. The skin of the unpasted hands may be stained with allergens such as pollen and insect mites, causing the rubbing to become more and more itchy, aggravating local irritation and redness and discomfort.
The correct way to deal with it is to close the eyes, the head is slightly lowered, the eyes will shed tears after being stimulated by the fly, then blink your eyes again, let the foreign body flow with the tears, or wash it with water.
If the floc falls on the skin, mouth, nose, etc., do not rub it with your hands, wash your face with water, or gently wipe it with a paper towel.
3
Do not open the screens
Try not to open the window when there is a flying feather, so as not to fly into the house. If there is a flying feather into the room, you can spray water to avoid it from floating around into the respiratory tract, and wipe the surface and ground of the furniture, or use a vacuum cleaner to clean it in time.
When driving, try not to open the window to avoid flying into the car.
4
Do not leave clothes outside
In the severe period of fly floc, it is best to dry clothes indoors, otherwise it is easy to let clothes, sheets, sheets, etc. contaminate fly floc, and aggravate allergic reactions after use.
People with more severe allergic reactions can choose anti-allergic drugs such as desloratadine tablets, levocetirizine tablets, etc. Itchy and red skin can be used for topical medications such as deonider cream, mometasone cream, and butyclohydric acid cream.
Children can use drugs such as Uzoll ointment and Qiangyue cream. If the condition is serious, it should be treated in the hospital in time. ▲
