Why Do I Always Have a Runny Nose and Sneeze?
Nasal discharge and sneezing can be caused by various reasons, with common factors including colds, allergies, and changes in climate or environment.
Colds: Colds are caused by viruses transmitted through cold air. When these viruses enter the respiratory tract, they can cause nasal inflammation, leading to nasal discharge and sneezing.
Allergies: Some people are sensitive to pollen, dust mites, and other allergic substances. When they come into contact with these substances, the immune system releases excessive histamine, causing an inflammatory reaction, which then leads to nasal congestion, nasal discharge, and sneezing.
Changes in Climate or Environment: Exposure to dry air or harmful substances may also irritate the nasal mucosa, resulting in excessive mucus secretion and frequent sneezing.
In short, nasal discharge and sneezing are caused by colds, allergies, or environmental irritants. Maintaining a good indoor and outdoor environment, having a healthy diet, and avoiding allergic substances can effectively alleviate these symptoms. If symptoms persist or worsen, it is recommended to consult a professional.
