If the nose is thick and runny, it is often considered to have rhinitis or sinusitis. It is usually heavier in the morning and relieved in the afternoon. Treatment is usually based on local anti-inflammatory and anti-allergic treatment, and local vasoconstrictors can be used in the nasal cavity to shrink the nasal mucosa, which helps to keep the nasal cavity open and facilitate the outflow of nasal mucus. In life, pay attention to keep warm, avoid cold and exertion, participate in physical exercise appropriately, improve the body’s immunity, and minimize colds. Drink more water, eat less spicy and stimulating food, and avoid inhaling irritating odors.
