Why does eating hot and spicy food make your nose run?

When we eat hot food, the temperature inside our mouth rises rapidly, causing the temperature sensors in the surrounding nose and related areas to react, leading to vasodilation in order to regulate body temperature.

 

At this time, to regulate body temperature, blood flow to the nose increases, raising the temperature of the surrounding blood, which causes the nasal mucosa to produce substances, ultimately leading to a runny nose.

Why does eating hot food make your nose run?

 

When eating hot food, a runny nose often occurs more frequently during dry seasons or in dry air, as this phenomenon happens more easily when the nasal mucosa becomes dry or when there is less moisture in the air.

 

If this phenomenon continues to occur, you may need to suspect diseases such as allergies or bronchitis that cause excessive nasal discharge and take appropriate measures.

Therefore, the phenomenon of having a runny nose when eating hot food is usually a normal physiological response, but if these symptoms occur excessively, it is advisable to seek diagnosis and advice from medical professionals.

 

Additionally, it is important to always consume food at an appropriate temperature and to drink a suitable amount of fluids before meals to prevent dryness in the nose area.

 

​

The phenomenon of having a runny nose when eating hot food is a natural adaptation process of our body, but if excessive substance release occurs, more careful handling may be necessary.

 

Since there are various reasons for a runny nose, ranging from minor issues to serious illnesses, it is important to see a specialist if the symptoms persist or worsen.
