My brother, father, and I suffer from what we call "sneezing attacks." Sneezing constantly for 10-15 minutes with about 20-30 seconds between each sneeze. It is hysterical to an observer, but torture to the sneezer.

I hate it when you feel a sneeze coming, but it leaves

[dm_nimbus]

Turns out it's snot so easy to explain...

[tristanyt]

I force myself to sneeze just to make my head relax.

[NerdBigTimeRush]

If sneezing occurs to get irritants out of your nose, what happens when you "lose" a sneeze?

[Alice-cvqg]

Literally I was on my phone and I sneezed. Then I thought WHY DID I SNEEZE?! Why do we sneeze?! And then I came here to check out why 😅😁♥️

[iotaslair]

So what about people who sneeze more than once within a few seconds?

[SinisterSi]

What did the mushroom say after it sneezed? My cilia!

[megakev]

Why do you sneeze when looking at the sun?

I tried to sneeze through my nose once. I'm never trying it again. It felt like my nose was about to explode.

I love science like this. All these little things we dont actually understand about how and why our body works.

[aliyahabdussamd]

me: *sneezes once*

me: *sneezes twice*

me: *sneezes three times*

Uh oh, I feel another one coming ha-ha-HACHIOOSISOSOSO

[deelots]

I never sneeze. Sneezing is not normal

[ChaoticMoonNbd]

As a chronic sinusitis sufferer who is now pregnant and dealing with sinusitis at this exact moment, this was fascinating.

[JonathanAcostaValverde]

Through the nose? Sure, if you want to burst your eardrums and pop your eyes out of their sockets... LOL

[eagleeye]

I've been sneezing every three minutes for the last six days!
So much so that I am watching this video!

[ainulkabir]

*My sneeze ain't exit my nose, it be exiting my throat.*

[ReverseHigher]

I sneezed right before this video came on my "Watch Later" playlist. Cool timing, universe.

My nasal cavity has a scar adhesion in it from surgery, meaning only part of it works and only one nostril is 'open' the other is sealed over by scar tissue(in my head not on the surface that would look awful) this means when i sneeze i also sneeze out of my mouth because my one nostril cant remove the air fast enough making my tongue get pushed up and down as the air forces its way past so i sound like a chainsaw exploding which is never a good sound to make especially during lectures.

[musclebrainsmartypants]

This was way more interesting than I thought it would be!
