 Why does spicy food make our nose run?


  Ever experienced a runny nose after eating your favourite spicy and hot food? But shy does your nose run?

  During breathing, the hair and mucus trap harmful substances, thus prohibiting them from entering deep inside the body.  Now, spicy food items contain chemicals called capsaicin and allylisothiocyanate.

  When we eat such food items, the capsaicin and allylisothiocyanate travel through the pharynx and reach our nose.

  Here, the chemicals activate the heat sensing receptors, thus causing inflammation in our nose and irritation of the mucus. Hence, as a defense mechanism more mucus is produced in our nose to get rid of these chemicals, thus making our nose run.
