Why does a child have a runny nose even though he doesn’t have a cold?

In daily life, children are prone to catching colds. For example, they may catch a cold if their body is slightly cold, and then they will start to have a runny nose. However, sometimes children have no cold symptoms at all, but they have a runny nose constantly. In fact, there are many reasons for children's runny nose. In addition to colds being an important reason, there are also many other factors such as allergies, especially the following reasons are very common.

Why does a child have a runny nose even though he doesn’t have a cold?

1. Cold air stimulation

The cold air invades the lungs and the body responds by defending itself. Like sweat and tears, snot is a way to regulate heat and cold in the body. The weather is cold in winter, and the cold wind irritates the baby's airway, making it easy for a runny nose to occur. This is why babies often have a runny nose in winter. At this time, if the baby only has a runny nose and no other uncomfortable symptoms, parents do not need to worry too much. At this time, the mother only needs to let the baby drink plenty of hot water or wash the baby's face with hot water, and the baby can enhance his ability to resist cold. If over time, the cold has blocked the pores and sweat cannot be discharged, then the mother can boil water with ginger, green onions and cinnamon to remove the cold.

2. Cold

In the early stage of a baby's cold, the nasal discharge is mostly clear water, which gradually turns into purulent discharge after 3 to 5 days and then gradually heals, but the discharge will continue during this period. As the cold heals, the purulent components in the mucopurulent nasal discharge will gradually decrease. If your baby has a runny nose after catching a cold and having a fever due to the cold wind, it means that the condition has improved. A runny nose at this time may not necessarily be a bad thing. You can take some cold medicine that is suitable for your symptoms. My baby drinks Aichang.

3. Allergic rhinitis

If a baby has allergic rhinitis, he will usually have clear nasal mucus in large amounts, and he will sneeze frequently and have an itchy nose. This is mostly seasonal, especially severe in winter, and most babies with allergic rhinitis will also suffer from asthma. Parents should carefully observe their baby's symptoms.

4. Sinusitis

If your baby has yellow watery discharge from his nose with a noticeable foul smell, especially if he has a cold and the illness lasts for more than 10 days and he still has sticky, purulent nasal discharge, you should consider whether he has sinusitis. At this time, parents should take the baby to the hospital for a sinus X-ray or CT scan to rule out the possibility of a sinus cyst. This is usually caused by the mother's long-term inattention to the child's runny nose.

In addition, frequent runny nose may be caused by a lack of vitamin A and vitamin B, and treatment with these two vitamins can be effective.

What should be noted most is that some children with nasopharyngeal lymphadenopathy also often have a runny nose, but they also have symptoms such as severe snoring, dull face, and flat nose, which can seriously affect their development and posture. They should be treated in time, and parents should pay attention to it.
