Question

Why do we have running noses when we have a cold?

Answer 1

Hint: Runny nose is a result of catching a cold and it usually occurs when our immune system is allergic to certain conditions like pollen grains or change in weather, flu, sinus, common cold, etc.

Complete answer: A stuffy or congested nose occurs when the tissues lining it become swollen. The swelling is due to inflamed blood vessels.
1. The chemical histamine is partially responsible for triggering these symptoms as it can cause inflammation in the nasal passages and airways, resulting in either a blocked or runny nose.
2. The end result is swelling of the nasal passages as well as extra secretion of fluid from the tissue lining the nose and sinuses, to varying degrees.
3. If swelling occurs in the narrow airways in our nose, we experience a blocked nose, and the extra secretions produced to appear as mucus, giving rise to a runny nose.
4. Anti-histamines are the first of the conventional medicines that a seasonal allergy sufferer may use as these reduce the chemical response in the body which aggravates the symptoms.
5. Home remedies like taking hot steam with menthol also help in running nose and block the nose.

Note: A diet with herbs, spices like garlic, cloves, ginger, etc. and honey should be taken that boosts the immune system easily.
Massaging the body with some hot oil also helps to get relief from it.
Precautions must be taken by covering the nose from dust and allergens to avoid it.
