Why Do We Sneeze

The video explores the reasons behind sneezing, initially explaining it as a reflex to expel irritants and excess mucus. It delves into the role of cilia, tiny hair-like structures in the nose, which help reset the nasal environment after a sneeze. A study showed that cilia become highly active post-sneeze, acting like a broom to clear the nasal passage. However, in people with sinusitis, this cilia activity is impaired, suggesting a potential area for treatment development.

What differences were observed in the cilia of sinusitis sufferers compared to healthy individuals?

Why might chronic sinusitis be related to the cilia's inability to reset after a sneeze?
