The central urban area and southern urban area of Beijing entered the flying catkin period from April 7 to 10. Later in the northeast and northwest of the city, the catkins began to fly from April 8 to 11.
According to the Beijing Center for Disease Control and Prevention, poplar flowers are not flowers and willow catkins are not catkins. They are a mixture of the seeds released from the cracked capsules of willows and the attached hairs (flocs) on the seeds. In fact, willow catkins are the process of willow mother trees using wind to spread seeds.
These flocs can cause allergy in some sensitive people. When people touch willow pollen and small flying catkins, they will cause allergic reactions, and the main symptoms include itching, redness, swelling, tears, etc; The respiratory tract is characterized by clear runny nose, stuffy nose, frequent sneezing, itchy throat, cough, etc., and even asthma and asthma may occur in severe cases; Allergic symptoms such as dryness, redness, itching and wheal may also appear on the skin.
Beijing Disease Control Tips——
How to fight against flying catkins?
1. Sensitive people should be free from allergens
Like other allergies, sensitive people should be free from allergens and stay indoors during the day as much as possible. Flying catkins will last from half a month to one month, usually at noon. Sensitive people should try to avoid going out at this time. Even if they want to do outdoor activities, they should also be relieved when there are few willow catkins, such as in the morning and at night, after rain.
For indoor ventilation, close the screen window, pay attention to indoor hygiene, wet cleaning, and open the air purifier if necessary.
2. Pay attention to protection when going out
[Anti wadding into nose]
The flying catkins are small and easy to be inhaled into the nasal cavity, and then nasal congestion, runny nose and sneezing come one after another, which can even lead to more serious respiratory symptoms or diseases such as asthma and asthma.
Sensitive people need to wear masks for protection when going out. When using masks, they should follow their instructions. When wearing masks, they must completely cover the nose, mouth and chin. Keep the masks closely fitted to the face. The better the tightness, the better the protection effect.
[Anti wadding]
Flying catkins into the eyes are difficult to remove, which will cause redness, swelling and tears in the eyes of sensitive people. A large amount of dust and bacteria carried on the eyes will also cause inflammation.
Wear gauze, goggles, glasses, etc. when going out, especially those who go out on a bike, which increases the chance of flying catkins getting into the eyes. Be sure to protect your eyes.
[Wrap yourself]
For people with sensitive skin, try to avoid contact with flying catkins, otherwise the skin will itch and become inflamed. When going out, you should "wrap" yourself, wear hats, long clothes and trousers, and try to avoid direct contact between skin and flying catkins.
After the skin is stained with flying catkins, it is necessary to remove them in time, and it is better to wash them with warm water to help prevent allergy or reduce allergic symptoms.
Do not scratch when the skin has allergic symptoms. Gently tapping, cold compress, and applying antipruritic drugs can alleviate the symptoms.
3. Clean in time and pay attention to safety
After going out and returning, wash your hands first, clean your nose and face at the same time, and clean the flying catkins on your coat in time.
During the high incidence period of willow catkins, timely clean or spray water to wet indoor catkins, especially those attached to the surface of heating appliances such as electric heaters, furniture and floor surfaces; The room can be cleaned in time with a vacuum cleaner.
Regularly clean the interior of the car, and timely clean the flying catkins and dust.
Pay attention to fire safety. It is strictly prohibited to throw cigarette ends and ignite flying catkins with open fire.
Tips:
