Why is the outside of my nose itchy?

If the outside of your nose is always itchy, you may consider it as a skin disease, because the triangular area of ​​the nose is relatively sensitive, and the thickness of the cornea is thinner than other skin. Lack of moisture may lead to dry skin and inflammation, causing itching on the outside of the nose. You need to be careful about possible inflammation and skin stratum corneum disease, and you need to actively treat it.

Why does my nose itch?

Itchy nose often occurs in our daily life. Whenever our nose itches, we always like to scratch it with our hands to relieve the temporary discomfort. So, what exactly causes an itchy nose? Next, we will analyze it from the perspective of traditional Chinese medicine.

Dry and itchy nose is called "nasal dryness" in traditional Chinese medicine, which often induces patients to pick their noses and cause small nosebleeds. In this case, don't pick your nose with your hands frequently.

An itchy nose is a common symptom of rhinitis, and specifically it is the most important symptom of dry rhinitis. Traditional Chinese medicine calls it "dry nose". The disease is more common in people with weak constitutions and those who often inhale unclean gases. Patients feel dryness and discomfort in their noses, or a tingling or foreign body sensation, which often induces them to pick their noses, causing small amounts of nosebleeds. The occurrence of dry rhinitis is closely related to climate and occupational factors. It is caused by long-term stimulation of the nasal mucosa, which leads to atrophy of the mucus glands and reduced secretion, resulting in dryness of the mucosa and even superficial erosion.

Spring in the north is windy and dry, and the human body easily loses a lot of water through sweating and breathing. In addition, the weather change is unpredictable, which makes it easy to "get angry". Many people's nostrils are very dry and itchy, so they can't help but pick their noses with their hands. As a result, the more they pick, the more itchy it becomes, and even bleeding.

In addition, the air in spring is full of pollen. Coupled with the windy and dry weather, dust and animal fur also float in the air. These are allergens. When people come into contact with these allergens, they can easily develop allergic rhinitis.

Based on the reasons for itchy nose analyzed above, let’s now find out what we should do if our nose itches?

1. Avoid contact with allergens

(1) The number of dust mites in the room should be less than 20/m2; maintain the relative humidity of the living space below 60%, but too low (such as below 30%-40%) will cause discomfort; sweep the carpet; wash bedding and curtains. Mite allergens are soluble in water, and washing textiles can remove most of the allergens; use air purifiers and vacuum cleaners with filters.

(2) Avoid allergens during the corresponding pollen allergy season.

(3) Patients who are allergic to animal fur should avoid allergens.
