Seeing the "flying snow" in spring, many people's first reaction must be that "poplar flowers and elm pods have no talent, only to make snow flying all over the sky". Although it looks like snow all over the sky, it's really hard to breathe and cough. It's easy to cause allergies. Do you know what these white hairs are? How to prevent them in spring?
Willow and poplar are widely used in road greening in Henan Province, and the 'white wool' people see is the white wool on the seeds of poplar and willow.
After the female flowers are fertilized, they give birth to their own seeds. When the seeds are ripe, they will spread. At that time, they spread their white hair & lsquo; paragliders & rsquo; and flew far away.
It's worth mentioning that willows begin to age at the age of 20. The older the trees, the more catkins they will get.
These people need special attention!
The first are allergic rhinitis and respiratory diseases.
The allergy caused by catkins mainly occurs in the upper respiratory tract. When catkins are inhaled into the nasal cavity, they will cause strong irritation, runny nose, cough, asthma and other reactions, such as skin pruritus, conjunctival redness, etc., which will seriously affect sleep.
Because of the short respiratory tract and delicate skin, children are more likely to induce discomfort. In addition, parents need to pay more attention to children's poor awareness of protection.
