Why sneeze? Know what science tells… (Sneezing Scientific Reason)
- There is a very sensitive layer (Nasal Mucosa) inside our nose.
- When dust, pollen, smoke, virus, bacteria or any strong smell irritates this layer, the nerves present there immediately send an alert to the brain.
- The brain’s “sneeze center” (primarily part of the brainstem) sends messages to the body to sneeze.
- After this, the lungs take a deep breath and the muscles of the chest, throat and face together suddenly create strong pressure.
- Air comes out at a very high speed through the nose and mouth, due to which foreign particles also come out.
- That means sneezing is a cleansing process of the body, which protects our respiratory system.
