Prolonged rhinitis in children can cause narrowing of the nasal passages and affect ventilation, making them sleep poorly at night and open-mouth breathing. During the day, nasal congestion can cause poor mood and temper tantrums. It can also cause sinusitis, bronchitis, pharyngitis, otitis media, conjunctivitis, enlarged tonsils, and adenoid hypertrophy, which can affect breathing and lead to breathing and sleep disorders. Due to long-term open-mouth breathing, it is the child’s lips become thicker and teeth develop outward. In addition, children with rhinitis often have a lot of nasal mucus, because they can not blow their noses and stagnate in the nasal tract leading to otitis media, hearing loss, language development disorders and a lot of nasal mucus flowing backward into the abdominal cavity will stimulate the gastrointestinal mucosa, causing a loss of appetite leading to malnutrition, leading to various diseases and thus affecting the development of children.
