How do boogers get into your nose?

Boogers, also known as nasal discharge or rhinorrhea, are a mixture of mucus, dust, dirt, and other particles that are trapped in the nose.

Here is how they form:

1. Mucus production: The inside of your nose is lined with a membrane that produces mucus. Mucus is a clear, sticky fluid that helps to trap dust, pollen, and other particles that you inhale.

2. Dust and dirt inhalation: When you breathe in, you also inhale dust, dirt, and other particles from the air. These particles can get trapped in the mucus in your nose.

3. Nose blowing: When you blow your nose, you expel the mucus and trapped particles from your nose.

4. Booger formation: If you don't blow your nose regularly, the mucus and particles can build up and form boogers.

Some factors that can increase booger production:

- Allergies

- Colds and flu

- Sinus infections

- Dry air

- Smoking

- Deviated septum
