Coughing in children when pulling out earwax is usually associated with irritation of the vagus nerve and is normal. The outer ear canal is rich in neurovascular tissue, including the vagus nerve. When parents pull out earwax for children, the digging spoon may stimulate the neurovascular tissues in the external ear canal, resulting in coughing when pulling out earwax, which is a normal neurological reflex of the human body, cough reflex, and the coughing phenomenon will disappear after stopping pulling out earwax, so parents don’t need to worry about it too much. Some children may also cough if they are overly nervous when pulling out earwax, but due to individual differences, some people do not cough. It is worth noting that parents should avoid pulling out earwax for children on their own, so as not to damage the mucous membrane of the ear canal improperly, which may cause pain and bleeding in the ear.
