In autumn, individuals with allergic constitutions are prone to pollen allergies. Many are unaware of the causes behind autumn pollen allergies, mistakenly attributing them to colds resulting from poor physical constitution.In northern China, the primary sources of autumn pollen allergies are wind-borne pollen from weeds like mugwort, hop, ragweed, groundsel, and goosefoot. These airborne pollens inevitably enter the human body. While healthy individuals feel no effects from inhaling wind-borne pollen, those with allergies experience intense, excessive immune reactions.When pollen adheres to the mucous membranes of the respiratory tract or the conjunctiva of the eyes, triggering inflammatory reactions of varying severity, allergic individuals develop symptoms like conjunctivitis and rhinitis. Severe cases may progress to sinusitis, otitis media, asthma, or even plant-based food allergies. Without timely and effective treatment, patients' quality of life can be severely compromised.
Due to climatic and geographical factors, even the same type of pollen exhibits temporal and quantitative variations in distribution across different regions. Therefore, after undergoing allergy testing and identifying specific allergens at an allergy clinic, patients can determine the temporal and spatial distribution patterns of that pollen. Based on their residential location, they may opt for treatment in a different region—essentially "escaping" through travel. If such options are unavailable, attention should be paid to the following lifestyle details:
Prioritize indoor activities.Keep doors and windows closed to minimize airflow. Households with the means can use fresh air systems or air purifiers to further reduce pollen particle density per unit volume of indoor air. When driving, keep car doors and windows closed and use the internal air circulation mode.
Protect yourself during outdoor activities.During pandemic prevention periods, wearing masks and pollen-blocking glasses is essential whether protecting against COVID-19 or pollen allergies. Studies show that pollen-blocking glasses reduce eye conjunctival contact with pollen particles by approximately 65% compared to not wearing them. Comfortable pollen-blocking masks effectively adsorb and filter autumn pollen, providing significant respiratory protection for allergy sufferers.
Choose optimal times for outdoor activities.Pollen concentrations typically peak in the afternoon. If outdoor activities are unavoidable, try to go out during off-peak times—preferably in the early morning, evening, or after a light rain when pollen levels are lowest. Note that thunderstorms are ineffective at cleansing airborne pollen particles and can cause them to swell and break into smaller, more allergenic fragments. Therefore, avoid going out before or after thunderstorms.Patients with pollen allergies may remove masks or glasses more frequently to wipe nasal discharge or tears, making personal hygiene especially crucial during pandemic prevention periods. Additionally, promptly wash hair and change outer clothing upon returning home to remove pollen particles adhering to hair and garments.
If allergy symptoms persist despite these measures, seek guidance from a healthcare professional for effective, standardized anti-allergy medication.Common medication types include: nasal or inhaled corticosteroids, nasal or oral antihistamines, oral leukotriene antagonists, decongestants, and traditional Chinese medicine. Each patient's specific treatment plan is not fixed; it requires a healthcare professional to determine and adjust medications based on the severity of pollen allergies and actual symptoms.Patients experiencing initial or mild symptoms may first use over-the-counter medications under the guidance of a professional pharmacist. If these prove ineffective or provide poor relief after 1-2 weeks, consultation with an allergist is recommended. For individuals with prolonged autumn pollen allergies, unsatisfactory medication control, or reluctance toward long-term drug use, desensitization therapy may be considered.Doctors administer subcutaneous injections of pollen vaccines in progressively increasing concentrations based on the patient's skin test reactions to allergens. Once the target maximum concentration is reached, a fixed maintenance dose is administered while monitoring efficacy. The total treatment course typically lasts no less than three years, with an efficacy rate of approximately 80%.
