1、 Cold Air 'Ambush' Low-temperature winter air directly stimulates the nasal mucosa, causing vasoconstriction and decreased immunity, providing opportunities for bacteria and viruses.

2、 Dry Environment 'Test' Frequent indoor heating significantly reduces air humidity, making the nasal mucosa dry and fragile and losing its normal defense function.

3、 Virus and Bacteria 'Festivities' Winter is the peak season for respiratory diseases such as colds and influenza, and viruses and bacteria spread faster, increasing the incidence of rhinitis.

4、 Allergens 'Dormancy' Although there are relatively fewer allergens in winter, indoor dust mites, pet dander, and mold may still trigger allergic reactions, aggravating rhinitis symptoms.

02. Preventive Measures

2、 Maintaining Humidity Use a humidifier or place a basin of water to keep the indoor air moist. Avoid using heating for extended periods; regularly open windows for ventilation to keep the air fresh.

3、 Boosting Immunity Maintain a balanced diet and eat foods rich in vitamins C and E, such as citrus fruits, strawberries, and nuts, to enhance the body's resistance. Engage in moderate exercise and get enough sleep to improve the body's immunity.

4、 Personal Hygiene Wash your hands frequently and avoid close contact with people who have colds. Regularly clean your home environment to reduce the growth of dust mites and bacteria.

5、 Avoiding Allergens For known allergens such as dust mites and pet dander, try to avoid contact. Keep your home clean, and regularly change bed linens and pillowcases.

1. Nasal irrigation: Using saline to irrigate the nasal cavity helps clear nasal secretions, allergens, and bacteria, keeping the nasal cavity clean.

2. Steam therapy: Inhaling steam (such as hot water steam or steam baths) softens nasal secretions and relieves nasal congestion. Be careful to avoid burns.

3. Dietary adjustments: Drink plenty of water to keep your body hydrated. Avoid consuming excessive amounts of irritating food and drinks, such as spicy food and alcohol, to avoid aggravating nasal inflammation.

4. Massage and warm compress: Gently massage the sides of your nostrils to promote blood circulation. Applying a warm towel to your nose can help relieve nasal congestion and pain.

5. Medication: Use anti-allergy drugs, antibiotics, or nasal sprays under the guidance of a doctor to alleviate rhinitis symptoms.
