What happens when you put pepper in your nose?

1. Irritation: The pepper's active compound, capsaicin, binds to receptors in the nasal passages called TRPV1 receptors. These receptors are responsible for detecting heat and pain, so the capsaicin triggers a sensation of burning or stinging.

2. Sneezing: The irritation caused by the capsaicin also triggers a sneezing reflex. Sneezing is a natural protective mechanism that helps expel foreign particles from the nasal passages.

3. Runny nose: The irritation from the capsaicin can also cause the nasal passages to produce more mucus, leading to a runny nose.

4. Inflammation: In some cases, putting pepper in your nose can cause inflammation of the nasal passages. This can lead to swelling, congestion, and difficulty breathing.

5. Pain: In severe cases, putting pepper in your nose can cause intense pain. This is more likely to occur if you have a history of nasal allergies or sensitivities.

If you accidentally get pepper in your nose, it is important to rinse your nasal passages with water and blow your nose gently. If you experience any severe pain or difficulty breathing, seek medical attention immediately.
