Eli5: What happens when you sneeze? And why does it happen multiple times?

416 views

I’m one of those weirdos that enjoys a good sneeze, but I don’t understand what happens when you sneeze. Why does our body react in such a way? And why do we have it built into our systems? And why do they often come in multiples?

It’s your nose ejecting unwanted material. A [good sneeze](https://www.nationalgeographic.co.uk/science-and-technology/2020/04/see-how-a-sneeze-can-launch-germs-much-farther-than-6-feet) can blast whatever pathogen is up your nose up to 27 feet away. I can’t find a link now (sad face) but a bunch of researchers simulating a house party, dropping blue dye in their nostrils and irritating their noses to create sneezes covered the whole room in “germs” in a frighteningly quick time.

Two things puzzle me:

1. Why do I always sneeze twice?
2. Why are women’s sneezes so comparatively mild?
