It's hard to escape the spring, why are you still allergic in autumn?
"It's already autumn, why are you allergic again?" Many people think that pollen allergies only occur in spring. In fact, autumn is also the season for pollen allergies.
According to Guan Kai, assistant to the director of the Allergy Department and deputy chief physician of Peking Union Medical College Hospital, many people do not know the cause of "autumn pollen allergy". When they encounter symptoms of sneezing and runny nose, they think it is "heat cold" or "chronic cold". ".
In fact, the pollen that easily causes allergies is not the fragrant, colorful ornamental flowers, but the pollen of trees or weeds.
Experts say that in the north where allergies are common, the main source of pollen allergy in autumn is the wind-pollinated pollen of wormwood, humulus, ragweed, Kochia scoparia, quinoa and other weeds. These pollens are unavoidably spread through the air by wind. The ground is sucked into the body.
Ordinary people do not have any perception of inhaling wind pollen, but for people with allergies, they will have a strong and excessive immune response.
Runny nose, sneezing, itchy skin... When pollen attaches to the respiratory mucosa and conjunctiva of the human body to cause inflammation, people with allergies will have symptoms of conjunctivitis, rhinitis, and severe sinusitis, otitis media, asthma, etc. The problem is that some patients have gradually developed allergic reactions to plant-derived foods.
If you do not get timely and effective treatment, it will cause serious damage to the quality of life of the patient, and reduce the efficiency of work and study.

Desensitization treatment is the only way to change the natural course of allergies
Allergic symptoms should be treated with effective and standardized anti-allergic drugs under the guidance of a professional doctor.
Guan Kai reminded that the specific medication plan of each patient is not static, and it is necessary for a professional doctor to decide the medication according to the patient's pollen allergy and actual symptoms and adjust it in a timely manner.
During the epidemic, patients with first onset or mild symptoms can use over-the-counter drugs under the guidance of a professional pharmacist. If the use is ineffective or not effective for 1-2 weeks, they should go to the allergy department for treatment.
In addition, experts said that desensitization treatment is a vaccine treatment method for allergic diseases, and it is also the only treatment method recognized by the World Health Organization that can change the natural course of allergic diseases.
If the symptoms of autumn pollen allergy sufferers last a long time each year, the medication control is not satisfactory, or they are unwilling to use medication for a long time, desensitization treatment can be considered.
But desensitization treatment is a long process, the total course of treatment is usually no less than 3 years, but the effective rate can reach about 80%.

Pollen allergies, can't cause it, only hide!
The best way to prevent pollen allergy is to avoid allergens as much as possible.
Guan Kai said that even if the pollen of the same species is distributed in different regions, there are differences in time and quantity. Therefore, after allergic patients have identified the allergen, they can pay attention to the pollen concentration broadcast in each region, choose different places for treatment, and borrow for business or travel. Hide for a while".
In addition, pay attention to these details in daily life:
1. Mainly indoor activities.
Patients with pollen allergies should close doors and windows to reduce air flow, and use an air purifier to reduce indoor pollen concentration.
When driving out, the doors and windows should also be closed, and the air circulation mode should be adopted.
2. Outdoor activities need protection.
During the epidemic prevention and control period, whether it is anti-coronavirus or anti-pollen allergy, you should try to wear a mask when you go out, and you can also wear anti-pollen glasses.
Experimental results show that wearing anti-pollen glasses can reduce about 65% of the pollen particles in contact with the eye conjunctiva.
3. Choose time for outing activities.
Pollen concentration tends to be higher in the afternoon. When you go out for activities and go out at the wrong time, try to travel in the morning, evening or after light rain when the pollen concentration is the lowest.
It should be noted that thunderstorms are poor in cleaning pollen particles in the air. Do not go out before and after thunderstorms.
4. Pay attention to personal cleanliness.
After going home, you should wash your hair and change your coat in time to remove the pollen particles adsorbed on your hair and clothing.
