Itchy
nose, stuffy nose, runny nose, sneezing.. Allergic rhinitis attacks are miserable. Experts say that allergic rhinitis induced by pollen in summer and autumn has passed its peak, but patients with a history of allergic rhinitis still need to take precautions because of the extended pollen season and stronger pollen sensitization this autumn.
“Weed pollen is the main pollen allergen in autumn. The pollen particles of Artemisia, Humulus and Ambrosia are small and easy to disperse with the help of dry air.” Zhou Weikang, an expert from the National Health Science Popularization Expert Bank and chief physician of Allergy Department of Chongqing People’s Hospital, said that when the air is dry and the relative humidity is less than 50%, there are two or three levels of wind conditions, which are more suitable for the spread of weed pollen. Yin Jia, chairman of the Allergy Physicians Branch of the
Chinese Medical Association, said that global warming and greenhouse effect would lead to prolonged pollen season, increased pollen production and increased sensitization. Rainstorms and floods in some parts of China in summer and autumn this year may cause Humulus scandens, which likes humid environment, to grow vigorously and prolong the pollen season. In September and October, a large number of Humulus scandens pollen spreads in northern China, which can easily cause severe allergic rhinitis and even allergic asthma.
“At present, the peak of allergic rhinitis induced by pollen in summer and autumn has passed, but due to the extension of pollen season, some people still have symptoms.” Yin Jia said that in addition, allergic symptoms occur outdoors in autumn, especially in places with more green plants, not necessarily pollen allergy, but also allergic rhinitis induced by mold, because the concentration of mold is very high in places with soil and plants. How to prevent allergic rhinitis in autumn in
daily life? The expert suggests, when outdoor come back, usable brine or clear water rinse nasal cavity and face; Pay close attention to indoor air quality and humidity, humidifier can be used when necessary; Hold to proper motion, ensure enough Morpheus; Clean household environment regularly, often sweep the place that dust mite and pollen gather. Sun Chen, a resident dermatologist at
Peking Union Medical College Hospital, said that for patients with allergic rhinitis, avoiding contact with allergens is the most basic and effective treatment. Other treatments include the systematic use of antihistamines and the use of nasal sprays containing corticosteroids or antihistamines.
