Runny nose, itchy eyes, and sneezing—what's the cause?

Generally, symptoms such as runny nose, itchy eyes, and sneezing may be caused by weather changes, foreign body irritation, viral colds, allergic rhinitis, sinusitis, or other factors. If discomfort occurs, seek medical attention promptly. Detailed analysis is as follows:

1. Weather Changes

When temperatures suddenly change or one remains in a cold environment for a prolonged period, the nasal passages and eyes might be stimulated by cold air, triggering sensitive reactions such as runny nose and sneezing. The eyes may also feel itchy due to dryness or cold wind irritation. It is important to keep warm, avoid prolonged exposure to cold environments, and engage in appropriate exercise to enhance immunity.

2. Foreign Body Irritation

Inhaling dust, smoke, or tiny particles into the nasal passages, or having foreign objects such as sand, eyelashes, or debris contact the eyes can stimulate the nasal passages and eyes, causing sneezing, runny nose, and itchy eyes in an attempt to expel the foreign substances. It is recommended to promptly clean any foreign bodies from the nose and eyes.

3. Viral Cold

Exposure to rain or cold, sudden climate changes, and similar factors may lead to viral colds. Viral infections cause inflammatory reactions in nasal mucosa and eye tissues, resulting in increased secretions and sensations of itching. Symptoms such as sore throat and cough may also appear. Under the guidance of a qualified physician, medications such as Isatidis Radix Granules, Bupleuri Decoction Granules, or Wind-Cold感冒Granules may be used for treatment.

4. Allergic Rhinitis

Allergic rhinitis is related to exposure to allergens. When allergens enter the body, the immune system mistakenly identifies them as harmful substances and mounts an excessive response, releasing chemical mediators such as histamine. This can lead to nasal mucosal congestion and increased secretions, while also stimulating eye tissues and causing itching. Symptoms such as nasal congestion and watery nasal discharge may also occur. It is recommended to follow medical advice and use medications such as Azelastine and Fluticasone Nasal Spray, Triamcinolone Acetonide Cream, or Budesonide Spray for treatment.

5. Sinusitis

Sinusitis is an inflammatory condition of the sinus mucosa, usually caused by bacterial infection. Inflammation causes increased secretions within the sinuses, which drain through the nasal passages as nasal discharge. The inflammation may also affect the eyes, causing itching, and may be accompanied by headaches and facial tenderness. Treatment should follow medical advice and may include medications such as Tongqiao Nasal Inflammation Tablets, Biyuanshu Oral Liquid, or Amoxicillin Capsules.

In daily life, ensure adequate sleep, which helps enhance the body's resistance and promotes recovery from illness.
