How to relieve nasal congestion in allergic rhinitis and improve nasal breathing

Allergic rhinitis nasal congestion can be relieved through methods such as saline nasal irrigation, intranasal corticosteroid sprays, oral antihistamines, precise avoidance of allergens, and regulating environmental temperature and humidity. The appropriate approach should be selected based on the severity of symptoms. If nasal congestion persists for more than two weeks or is accompanied by headache or reduced sense of smell, prompt medical attention is necessary.

1. Saline nasal irrigation: Irrigate the nasal cavity once or twice daily to remove residual allergens and inflammatory secretions, reduce nasal mucosal congestion and swelling, and gently improve airflow. This method is mild, non-irritating, safe, effective, and suitable for long-term use across all population groups as a foundational supportive measure.

2. Intranasal corticosteroid sprays: For example, mometasone furoate spray, which acts directly on the nasal mucosa to suppress allergic inflammatory responses and rapidly relieve nasal congestion. These should be used strictly according to the recommended dosage to prevent misuse, and consistent, regular use is required to maintain therapeutic effects.

3. Oral antihistamines: Such as loratadine or cetirizine, which block histamine-mediated allergic reactions, reduce nasal mucosal congestion, and improve airflow at its source. Select an appropriate formulation under medical guidance and avoid combining with other similar medications.

4. Precise allergen avoidance: Identify specific allergens through testing. During pollen season, minimize outdoor activities and wear protective masks. For dust mite allergies, regularly sun-expose bedding and maintain household cleanliness. For pet allergies, reduce exposure to animal dander. Minimizing contact with triggers helps prevent nasal congestion at the source.

5. Regulating environmental temperature and humidity: Maintain indoor humidity between 50% and 60% to avoid worsening discomfort due to dryness or excessive moisture. Avoid tobacco smoke, fumes, and irritating odors, and ensure good indoor ventilation to help alleviate nasal congestion.

Maintain daily nasal hygiene and avoid picking the nose. Follow a regular sleep schedule to boost immunity, consume a diet rich in vitamin-containing fruits and vegetables, and avoid spicy or cold foods that may irritate the nasal passages. Engage in moderate exercise appropriately to improve respiratory function and support sustained nasal patency.
