|At one time or another everyone has pondered the exact mechanics behind a sneeze. With every breath inhaled, we take into our body tiny particles of dust and irritants.
As air moves up the nasal cavity, nose hairs and mucus collect these ‘rogue’ particles. Your body is triggered to shut the epiglottis (at the back of the throat) contract the chest and let out a huge sneeze! ‘Photic sneezers’ are those who feel they have to sneeze when they look into bright light – this is hereditary on one side of the family.
Sternutation, the act of sneezing, is actually good for the body, as it keeps the bronchial tubes that carry air from your nose to your lungs clear, and in good working order. This is particularly beneficial when your nose is clogged during a cold or flu – as a powerful sneeze can clear the nose in milliseconds!
