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.
