Frequent nasal congestion in newborn babies is often attributed to their weakened immune system and the special and delicate physiological structure of the nasal cavity. Additionally, the presence of respiratory tract infections and nasal cavity-related diseases can also increase the likelihood of nasal congestion in babies. When parents notice nasal congestion in their children, they can improve the situation by properly cleaning the baby's nose or keeping them warm, allowing the nasal cavity to return to its unobstructed state.
1. Immunity deficiency: Children with low immunity and poor resistance are prone to colds and other illnesses when not properly kept warm.
2. Physiological factors: Compared to adults, children's maxillary and skull bones are not fully developed, making the nasal cavity more sensitive. Exposure to cold air or airflow with a high bacterial load can directly stimulate the nasopharynx, causing congestion and swelling of the blood vessels and mucosa, increasing nasal secretions and scabs, further narrowing or even blocking the already narrow nasal cavity.
3. Disease factors: Respiratory tract infections are common causes of nasal congestion in children. Additionally, nasal conditions such as nasal polyps, deviated nasal septum, nasal foreign bodies, or tumors can also lead to nasal congestion in babies.
4. Medication factors: Medications that cause congestion of the nasal mucosa, such as the antihypertensive drug reserpine taken by pregnant women, can also lead to nasal congestion in newborn babies.
